Don’t take our word for it

Was shocked as I did not expect it to be so TINY! It is literally the size of two lipsticks. Charges my phone from 0 to 50% in about 25 minutes and that’s pretty impressive for a little guy. Just bought another for my wife. Great Job!

I love it! I have to tell a little story about it. A few weeks ago we had a hurricane and I wanted to record videos with my iPhone and brought a Pix Mini with me to be on the safe side. When taking out the iPhone, I lost the power bank in the storm on the beach (where the arrow is pointing).Two days later we looked for it and found it again! Despite the storm and the sand and the rain, it was perfectly intact and had lost none of its function. Excellent!

The only powerbank I carry now. Love the tiny size and weight, I have completely stopped using my old bulky powerbank already!

What Is a Power Bank? Everything You Need To Know About Charging On The-Go

Running out of battery can be a big problem, especially when you might not have access to a wall outlet to charge your phone. Cue power banks! A power bank can keep your phone full of battery without an outlet, so you’ll never have to miss a selfie opportunity or a call from your mom. It’s time to get charged up to learn all about power banks, from their purpose, the different types, and why you need one!

What is the Purpose of a Power Bank? Top

The purpose of a power bank is to recharge battery-powered electronics when you’re on-the-go! A power bank can be small enough to fit in your or they can be larger with a higher capacity.

Power banks are used to charge cell phones, tablets, speakers, and even laptops! If you can plug it in a wall to charge, chances are a power bank can charge it.

When Was the First Power Bank Made? Top

The first portable power bank was created in 2001 by a Chinese company called Pisen. The original design was two AA batteries pieced together by a circuit! It made its public debut at the Las Vegas International Consumer Electronics Show.

The first power bank was bulky and had a short battery life. Today, there are much more sophisticated and compact designs with far superior battery life. Most modern power banks can fit in the palm of your hand and charge your smartphone several times before running out of battery.

Who Invented the First Power Bank? Top

The first power bank, the Power King, was invented by a Chinese company called Pisen. An Antarctic Expedition Team requested a portable charger for their video cameras and other devices. Cold temperatures would compromise the battery life of their equipment, so a power bank was a necessity for the trip.

What Are the Different Types of Power Banks? Top

Power banks come in a variety of different shapes and sizes. Some power banks have multiple uses in addition to charging your electronic devices!

The different types of power banks include:

  • Block power bank
  • Credit card power bank
  • Keychain power bank
  • Wireless power bank
  • Flashlight power bank
  • Speaker power bank
  • Novelty power bank
  • Bluetooth earbud power bank
  • Lantern power bank
  • Solar power bank
  • High capacity power bank

Block Power Bank

Block power banks are one of the most common types of portable chargers. The blocks can come in the shape of a slim rectangle, a log, or a wider rectangle. This type of power bank is great for keeping in your bag or backpack for those moments when you need some extra juice on-the-go.

Credit Card Power Bank

A credit card power bank is a portable charger with a slim rectangular design, hence its name. This kind of power bank fits comfortably inside your without feeling bulky. The discreet design allows you to slip it inside small places like a wallet or padfolio without taking up a ton of room.

Keychain Power Bank

You never know when you might find yourself with a phone on low battery and no wall outlet. A keychain power bank is compact enough to add to your keyring and take with you everywhere! The next time you need a quick charge, you’ll have your power bank easily accessible.

Wireless Power Bank

Keeping track of cords can become a nuisance. A wireless power bank works by simply resting the back of your phone on top, and letting your battery charge. Before you get a wireless power bank, be sure your device is compatible with this type of charger.

Flashlight Power Bank

If you go camping, fishing, or hiking, a flashlight power bank is a necessity. Not only does the flashlight provide safety at night, but it can also charge your phone. It’s also a good idea to keep a flashlight power bank in your home in case of a power outage.

Speaker Power Bank

Next time you head to the beach or to a picnic, don’t forget to grab a speaker power bank. Keep your phone charged while listening to your favorite playlist with this compact power bank. It’s also handy for bike rides or while working on an outdoor project.

Novelty Power Bank

There are some power banks that don’t look like a power bank at all, like this Rubik’s Cube! The best part is you can twist the colored blocks while your phone charges. It’s still compact and fits in the palm of your hand, so you don’t have to worry about running out of space in your bag.

Bluetooth Earbud Power Bank

This power bank not only works as a portable charger for your phone, but it’s also a port to store and charge wireless Bluetooth headphones! One end of the power bank has the connection to charge your device, and the other has two slots for the earbuds.

Lantern Power Bank

Anyone who is outdoorsy will want a lantern power bank. Use the light when you need it, and then charge your phone at the same time. With this power bank, you can use a charging cable, or you can place your phone on top to wirelessly charge it.

Solar Power Bank

Go green with a solar power bank! Leave your power bank in the sun to charge it up, and then connect it to your phone. A solar power bank is great to use over an extended period because you don’t have to worry about needing a wall outlet to recharge it.

High Capacity Power Bank

High capacity power banks provide a lot of power and have a battery with 20,000 mAh or higher. These power banks can charge multiple devices at once, or one device multiple times before needing to be charged.

There is truly a different type of power bank to satisfy every need. Whether you end up having one favorite or multiple models for different occasions, a power bank is always a good item to keep on hand.

What Does mAh Mean? Top

mAh means milliamp hour. It is a unit of measurement used for electric power, specifically for batteries. A battery that has a higher mAh will have more power and battery life.

For rechargeable batteries found in power banks, the mAh shows how much charge the battery can hold, and how long it can power another electronic before needing to be charged.

How Do I Know My Power Bank Capacity? Top

Before you invest in a power bank, you’ll want to know how long the battery will last. Knowing the capacity of your power bank will help you make sure you get one that will meet your needs. Use the equation below to find the approximate battery life of your power bank.

If your power bank has 10,000 mAh, you would divide that by the mAh of the device you want to charge. A quick online search can tell you the mAh of your device if you aren’t sure or can’t find the battery. For example, an iPhone XS uses a 2,658 mAh battery. Using the equation, it would take 3 hours and 7 minutes of charging your iPhone XS before your 10,000 mAh power bank ran out of battery life.

Which Type of Power Bank is Best? Top

The best type of power bank will have a mAh that is higher than the device you want to charge. The larger the battery is on your phone or other electronic device, the more power you’ll need from your power bank to charge it.

For example, if your electronic device has a battery with 2,000 mAh, you’ll want to get a power bank that has at least 2,000 mAh or more. That way, you’ll be able to get at least one full charge for your device without having to recharge the power bank.

What Is the Difference Between a Power Bank and a Portable Charger? Top

There is no difference between a power bank and a portable charger. Both names can be used to refer to the exact same battery pack you use to charge a device.

A power bank has several nicknames including:

  • Battery pack
  • Fuel bank
  • power cell
  • Back-up charging device
  • Wireless charger
  • Portable charger

Regardless of the name you want to use for your power bank, you’ll be thankful you have it handy when your electronic device needs some extra juice!

What Power Banks Are Allowed on Planes? Top

According to the Transportation Security Administration, power banks containing a lithium ion battery must be packed in a carry-on bag. The reason why power banks are not allowed in checked bags is because the battery contains potentially hazardous flammable materials.

The Federal Aviation Administration (FAA) does not allow any type of battery onboard an aircraft that exceeds 27,000 mAh. Keep these guidelines in mind before flying and be sure to properly pack your power banks!

What Are the Advantages of Power Banks? Top

Now that you know what a power bank is, you might be wondering if a power bank is worth it. There are several advantages to having a power bank you should consider before getting your own.

The advantages of power banks include:

Easily Portable

Most power banks can fit in the palm of your hand, making them easy to take with you anywhere! You won’t have to worry about it taking up too much space in your bag or

Customizable

Power banks come in a variety of colors and styles you can choose from. You can also add different designs to your power banks to make it your own.

Affordable

You don’t have to spend an arm and a leg to get a quality power bank. Most power banks are under 20 and will keep your phone charged whenever you need it.

Reusable

Each time you need to charge your electronic devices, you don’t have to get a new power bank. You can recharge and reuse the same power bank over and over.

Fast-Charging

We don’t always have time to wait for our phone battery to charge. Thankfully, you can take a power bank with you to quickly charge your phone on-the-go.

Reduces Worry of a Dead Cell Phone

Power banks are an accessory worth having! If you have smartphone or other electronics that you need to keep charged, then you’ll want to have a power bank with you.

The Bottom Line

A power bank can make a huge difference while camping, traveling, or attending a festival. It can help prevent your phone, tablet, or other electronic device from running out of battery. You never know when you might be stuck without a wall outlet, so keeping a power bank nearby can save you in the long run.

The Best Power Banks of 2023

We tested power banks from Nitecore, Goal Zero, Anker, and more, to help you find the best model to keep your phone, tablet, laptop, or other gadgets charged.

In 2023, nearly every gadget and gizmo that we use has a battery. Our phones are the primary example, but nearly everything — from headlamps to headphones — has built-in rechargeable batteries.

As a result of our rechargeable world, portable power banks have become a standard part of everyday life. When traveling, power banks offer convenient on-the-go charging that eliminates the need to hunt down an outlet. For outdoor enthusiasts, compact power banks go along on every camping trip, thru-hike, and bike-packing journey.

In recent years, power banks have improved exponentially. As we all grow increasingly reliant on our electronic devices, power banks have become smaller, lighter, and more capable than ever before.

To compile this list of the best power banks, we combed the market for the most popular, innovative, and well-regarded models — and then conducted extensive testing at home and in the field to determine the best model for every need and budget. We charged phones, cameras, laptops, and even other power banks. We dropped and lightly abused over a dozen models to determine durability and longevity. In the end, we were left with a clear understanding of which models are worth their weight and price tag. These are the best power banks on the market today.

To learn more about what to look for when purchasing a power bank and our rigorous testing process, check out our comprehensive Buyer’s Guide, Comparison Chart, and FAQ sections below.

Nitecore NB10000 Gen II

Pros

  • Impact-resistant and generally durable
  • Lightweight with a thin profile
  • Charges quickly
  • Low-power setting for sensitive devices

Cons

Now in its second generation, the Nitecore NB100000 (60) is a lightweight, no-frills power bank that seriously impressed during testing. This minuscule unit is one of the smallest 10,000 mAh banks on the market. It fits easily in any. and it weighs just over 5 ounces — excellent stats for a power bank that fully charged an iPhone 13 to 100% two and a half times — exactly as the brand claims.

The NB10000 isn’t the most heavy-duty or luxurious power bank on the market, but it simply performs well in every category without any major flaws or weaknesses. Sure, the battery power indicator light isn’t the most precise, but that’s a nit-picky criticism in a compact power bank. Ultimately, the NB10000 provides reliable portable power for charging small devices.

Our 2-foot drop test didn’t leave a scratch on the Nitecore’s carbon fiber exterior, so we especially recommend this power bank for outdoor use. It’s light and packable enough for ultralight thru-hiking, and it contains enough power to keep a phone charged for quite a long time — depending on phone use, of course.

Compared to the first generation of the NB10000, the second generation offers increased USB-C output for faster charging. It also has a “low current mode,” which is useful for sensitive devices with small batteries such as Smart watches and Bluetooth earbuds.

If you need to charge two devices at once — the NB10000 has you covered. Additionally, it has “pass-through charging,” which allows users to tap into the NB10000’s outputs while it is plugged into a wall outlet.

Charmast 10400 mAh Power Bank

Specs

  • Capacity 10,000 mAh
  • Weight 6.6 oz
  • Size 3.56 x 2.44 x 0.87
  • Outputs USB-A (2x), USB-C (1x)
  • Inputs Micro USB, USB-C
  • Included cables USB-A to USC-C, USB-A to micro USB

Pros

  • Versatile charging configuration
  • Good value
  • Compact
  • The power bank itself recharges quickly

Cons

For 23, this.sized Charmast power bank is an excellent affordable option for recharging small devices around the house and during weekend getaways. Sure, there are less expensive power banks of this size on the internet, but this one actually works and has great quality for the price.

With two USB-A outputs plus an in/out USB-C and a micro USB output, this Charmast works with all sorts of cables. It can theoretically charge up to three devices at a time, though it will drain very quickly under that kind of strain. During our testing, it delivered power to headphones, smartphones, and smartwatches in a timely fashion. It pumped an iPhone 13 from 0 to 100% and again from 0 to 92% in a single full charge. Compared to similarly-sized power banks, the Charmast reloads quickly when plugged into a wall outlet with its included cable.

Though this unit is a bit bulkier and heavier than our top overall pick, it still fits easily into a without fuss. The plastic casing doesn’t boast any listed waterproofing stats, but it held up perfectly well to our drop test with only minor scuffing.

Goal Zero Sherpa 100PD

Specs

  • Capacity 25,600 mAh
  • Weight 1.5 lbs.
  • Size 7.7 x 3.81 x 1
  • Outputs Wireless, USB-C (1x)
  • Inputs USB-A (2x), USB-C (1x)
  • Included cables 39 USC-C to USB-C cable

Pros

  • Powerful enough for charging laptops and tablets
  • Durable casing
  • Wireless charging

Cons

During our testing for this roundup, we focused primarily on compact.sized power banks in the 10-20k mAH range. Though these small devices are great for charging small devices on the go, they aren’t suitable for larger devices like laptops.

The Goal Zero Sherpa 100PD (199) is larger than most power banks on this list. It weighs 1.5 pounds, and it won’t fit in a That said, it’s still relatively compact, and it’s the perfect choice for airline travel or car camping, especially when a charged-up laptop is essential.

Compared to the smaller banks we tested, the Sherpa boasts several significant upgrades. First, it offers wireless charging. Just set a compatible smartphone or another device on the charging pad and it’ll power up sans cable.

A small display screen keeps the user informed on outgoing wattage, remaining battery life, and more. It’s far more informative than the standard series of indicator lights that most small power banks have.

The Sherpa charged an iPhone 13 from dead to 100% a whopping seven times using a USB-C to USB-C cord. The brand advertised eight full charges, but this figure depends on many variable factors. In any case, the Sherpa is about four times more powerful than most 10k mAh power banks in this regard. Using the wireless charging surface, the phone fully charged in about 100 minutes.

The Sherpa fully charged a MacBook Air over two times before it ran out of steam — more than enough for a weekend of off-grid computing.

Dark Energy Poseidon Pro 10200

Specs

  • Capacity 10,000 mAh
  • Weight 9.6 oz.
  • Size 6 x 3.25 x 0.63
  • Outputs USB-C (1x), USB-A (1x)
  • Inputs USB-C (1x)
  • Included cables 3′ USB-C to USB-C cable

Pros

  • Extremely durable
  • Built for extreme conditions
  • Waterproof and fully submersible

Cons

In terms of durability, the Dark Energy Poseidon Pro (120) is miles ahead of nearly every other power bank. According to the brand, it can be fully submerged in water for up to 45 minutes, frozen for four weeks, and dropped from 75 feet in the air. Though we didn’t test these bold claims exactly, we used and abused the Poseidon Pro for several weeks, dropping it in the snow, tossing it loose into a backpack, and making no attempt to protect it from harm. It continues to look and perform like new.

This power bank’s bulletproof nature does come with a slight weight increase. It’s about 3 ounces heavier than other power banks with comparable capacity. Still, that’s a small price to pay for reliable power in extreme conditions. If you’re heading to the ends of the earth, this is the right power bank to pack.

All power inputs and outputs on the Pro are hidden beneath a rugged mini door. A small LED flashlight sits next to the USB-A and USB-C ports. Four battery indicator lights relay the key information that users need.

We managed to squeeze two full charges out of the Pro with an iPhone 13 — competitive stats in the 10k mAh category.

Goal Zero Flip 24

Cons

This Goal Zero Flip 24 (30) is one degree smaller than the common 10k mAh power bank size class. It’s about the same size as a 15-pack of gum, and it charged an iPhone 13 twice (almost, 81% on the second charge). It’s great value for 30, and it adds valuable peace of mind on long hikes and bike rides.

Unlike most power banks on this list, the Flip 24 only has USB-A input and output. It’s not surprising for such a small bank, but it might be annoying for folks without a compatible cable. Plus, USB-C charging tends to be faster than USB-A. The Flip 24 will charge your phone slower than most other options on this list.

On the plus side, the Flip 24’s built-in USB-A stick is quite convenient. It plugs directly into compatible ports and charges right up without a cord. The battery indicator lights light up when the user pressed the USB stick, which doubles as a button — product design panache.

For phones, earbuds, and smartwatches, the Flip 24 is a nifty little backup battery. If you need to charge larger devices, go with a power bank with greater capacity.

Anker PowerCore III Elite

Specs

  • Capacity 25,600 mAh
  • Weight 1.3 lbs
  • Size 7.22 x 3.24 x 0.94
  • Outputs USB-A (2x), USB-C (1x)
  • Inputs USB-A (1x), USB-C (1x)
  • Included cables USB-C to USB-C

Pros

  • Lots of power capacity in a small package
  • Simple design
  • Intuitive single-button interface

Cons

Anker has a solid reputation for simple, long-lasting, and fast-charging power banks. The PowerCore III Elite (160) boasts an impressive 25,600 mAh of capacity — an excellent figure for a power bank that’s only about seven inches long.

Most power bank users can get by with 10k mAH — a perfectly suitable capacity for a weekend’s worth of phone and earbud charging. The PowerCore III Elite is a major step up — it contains more than double the capacity of most of the power banks on this list. It’s potent enough to charge laptops and tablets, and it still manages to fit into most pants s.

Of course, the extra capacity has to come from somewhere. The PowerCore III weighs 1.3 pounds. That’s a bit heavy for backpacking. Still, compared to similar capacity power banks like the Goal Zero Sherpa 100PD, the PowerCore is relatively svelte.

The PowerCore III fully charged an iPhone 13 just over six times. Anker claims it can charge three devices simultaneously. During testing, it easily charged two smartphones at the same time.

The PowerCore dented easily during our 2-foot drop test, but it went on working without issue. It’s a great compact choice for photographers or remote workers on the go.

Hinovo Magnetic Charger

Specs

  • Capacity 5,000 or 10000 mAh
  • Weight 4.5 oz. (5,000 mAh version)
  • Size 4.09 x 2.75 x 0.35
  • Output Wireless charging via magnetic connection
  • Input USB-C (1x)
  • Water resistance Unknown
  • Included cables USB-C to USB-C (1)

Cons

This compact power bank magnetically adheres to the back of compatible smartphones to deliver power on the go. Instead of waiting while your phone remains plugged into a cable, the Hinovo magnetic power bank (39) goes where you go. It’s fully mobile, and highly convenient.

Our Editor-in-Chief has been living with the Hinovo for months, and he appreciates its ease of use and straightforward design. The slim 5,000 mAh version immediately doubles a smartphone’s battery life without much-added bulk. The major downside of the Hinovo is that it’s only compatible with certain phones that are MagSafe compatible.

If you’re in for a long phone-intensive workday or cross-country Wi-Fi enabled flight, the Hinovo provides reliable assurance that your phone will survive the trip.

Otterbox Fast Charge

Cons

The Otterbox Fast Charge (35) is available in three sizes: 10k, 15k, and 20k mAh. We tested the 10k version, though all three models have the same design and two-port layout. With just one in/out USB-C and one USB-A put out, it’s a simple and effective power bank that works best with smartphones and small devices.

The “Fast Charge” Moniker sets up high expectations. This power bank fully charged an iPhone 13 from dead to 100% in just over 90 minutes. While this stat is competitive for a small power bank, it’s about the same as several other top performers on this list. This Otterbox is a reasonably fast-charging product, but it’s on par with its peers on this list, not necessarily superior.

Compared to the more durable options we tested, the Fast Charge has an all-plastic casing that feels a bit delicate and cheap to the touch. It survived our drop test and continued to function, but it just doesn’t have the feel of excellent build quality. Still, it’s a perfectly usable power bank.

The 15k version (45) is a nice middle ground between common power bank sizes. We expect it could charge a newer iPhone three or four times, a meaningful improvement over the 10k version.

BioLite Charge 80 PD Powerbank

Cons

  • Battery indicator is not super precise
  • Battery indicator doesn’t turn off while charging

This unassuming powerhouse came to be one of our tester’s favorite power banks by accident. After getting his sleek, lightweight Anker charger stolen on a recent climbing trip, the BioLite Charge 80 PD (80) — his backup bank — found its way into his backpack on several ultralight treks and long road trip adventures.

It takes a lot for a power bank weighing over a pound to end up in a backpacking kit, but for super remote excursions where energy efficiency was a must, this thing was a lifesaver for our tester. Despite its 16.4-ounce weight, it can charge a smartphone over 5 times (tested with an iPhone 11), a tablet twice (tested with an iPad Pro), and even a computer once (tested with a MacBook Pro).

While you don’t need all these devices on a backpacking trip, this is a welcome power source for road trips, wilderness photo/video shoots, or international travel. And, for those backpacking jaunts that have you off the grid for five days or more, it’s hard to beat the power-to-weight ratio that this delivers.

The two USB-A Quick Charge and single USB-C PD ports offer exceptionally fast charging. The bank also only takes 4.5-5 hours to soak up a full charge, which is better than some other models with similar capacity we’ve tried. Its durable plastic shell gives this an indestructible feel, and we haven’t noticed a scratch on it after many miles of rough use.

With a 20k mAh capacity, it has the inherent cons of being quite heavy and comparatively large, but is on par with other banks in its category. We do find the battery indicator to be somewhat lacking. It is a bit hard to gauge exactly how much power is left, and we don’t like that the light remains on while charging. Some energy could be saved by having it switch off after it’s been plugged in for a second, and it can get annoying at night if it’s not covered up.

These slight gripes aside, we think that the BioLite Charge 80 PD delivers reliable power in a packable, durable design. If pure ultralight minimalism is what you’re after, there are better options out there. But, for the adventurer in need of a bit more juice on their excursions for multiple devices, this would be a solid pick.

OKZU C10002Y

Cons

This ultra-slim 10k power bank (26) is marketed as a power source for electrically heated outerwear, but it also works perfectly well for all sorts of small electronics. It charged an iPhone 13 to the brims three times before needing a recharge itself — a great showing for a bank that weighs just 6.8 ounces.

We found that the C10002Y gets warm to the touch when plugged into the wall, but this is likely just a result of the thin plastic casing — not a major concern. Speaking of the casing, this definitely isn’t the most rugged power bank on our list. It feels like one significant chest-height drop onto a hard surface would be the end of it. We held our breath during the 2-foot drop test, and though it did survive, it sustained minor visible damage.

Four indicator lights convert battery levels — including one light that turns green when “fast mode” is engaged. Interestingly, this light turned green while charging an iPhone via the USB-C port, but not when charging earbuds via a USB-A port. It seems there is some kind of sensor in the OKZU that engaged fast charging mode when the receiving device has a compatible battery. Neat.

Generally, this is yet another sweet little power bank. It’s mega thin, and hardly detectable when sitting snugly in a Plus, it’s affordably priced at just 26.

Lion Trek Portable Solar Generator

Specs

  • Capcity 27,000 mAh
  • Weight 2.1 lbs
  • Size 8.54 x 5.47 x 1.57
  • Outputs USB-A (2x), USB-C (1x), 12V AC (1x)
  • Inputs USB-C (1x)
  • Included cables Wall outlet to USB-C

Pros

  • Features an AC outlet for charging larger devices
  • Durable casing
  • Easy-to-read display

Cons

In both size and capacity, the Lion Trek Power Bank (229) is the largest power bank on this list. At 2.1 pounds and 8.5 inches long, it takes some liberties with its self-described “portable” nature. Still, this power bank justifies its size with a massive 27,000 mAh of capacity and a handy AC power outlet. Unlike most of the options on this list, the Lion Trek packs enough power for laptops, tablets, and small appliances like lamps, TVs, and coffee grinders. It’s the perfect size for a long-term solo road trip — especially when paired with a compatible solar panel.

We’ve been testing the Lion Trek for several months. Though it’s a bit too big and inconvenient for airline travel, it’s been our go-to power bank for car camping. On a single full charge, the Lion Trek recharged an iPhone 13 nine times. It kept a MacBook Air alive for three days of frequent use. According to its display, the Lion Trek only used 5% of its total battery life to fully charge a pair wireless earbuds.

For some folks on the go, an AC outlet is a must-have. The Lion Trek is one of the smallest banks to include one. Additionally, the unit houses two USB-A outputs and one in/out USB-C port. For mobile remote workers, the Lion Trek can function as an ultra-compact solution for the solar-powered off-grid lifestyle.

Why You Should Trust Us

Every power bank on this list has earned its place through rigorous hands-on testing in the same real-world scenarios you’re likely to face. In the winter of 2023, author Austin Beck-Doss didn’t plug his phone or laptop into a single wall outlet for several months. Instead, he charged his devices exclusively via power bank. Through daily use and a series of standardized tests at home and in the field, Austin assessed the durability, performance, and capacity of innumerable brands and models. The recommended products on this list are the very best money can buy.

Power bank brands make lots of lofty claims about capacity, durability, and performance. Instead of simply trusting the statistics written on the side of the packaging, Austin put manufacturer claims to the test. Every power bank was fully charged to determine exactly how many times it could fully charge an iPhone 13 before depleting. Austin also measured the total time that each depleted power bank took to fully recharge once plugged into a wall outlet.

Our durability test involved prolonged regular use indoors and out, and a standardized drop test. Every bank was dropped exactly 2 feet onto a hard concrete surface to simulate the classic electronics fumble that we all experience from time to time. Some power banks ceased to function after a single drop. Of course, none of those models made the list.

Buyer’s Guide: How to Choose a Power Bank

For better or worse, most folks today feel a wave of concern when their smartphone battery drops below 20%. Phones, tablets, laptops, and other portable electronics pack a lot of utility — and we’ve grown reliant on them to conduct our everyday affairs.

pixy, mini, compact, power, bank

Power banks are physical stop gaps that prevent dreaded cases of DPS (dead phone syndrome). Whether you forgot to plug in overnight, or you’ve been traveling all day without access to an outlet, power banks are a lifeline for you and your portable electronics.

These days, power banks come in all shapes and sizes — from mini units that can dangle from a keychain to 25-pound behemoths. On this list, we focused on the most popular category: personal-use portable power banks. Portable is a subjective term. For this list, we only considered products that weigh about 2 pounds or less and fit easily into any backpack.

In this comprehensive buyer’s guide, we break down everything you need to know about power banks; capacity, charge times, inputs, outputs, solar capability, you name it. Our hope is that by using this guide, you’ll be able to hone in on the perfect portable power bank to suit your everyday needs.

What Is a Power Bank?

A power bank is a rechargeable battery that can transfer power to other electronic devices. Power banks are like wall outlets that you can take with you. Simply plug in your phone or laptop via a standard USB-A or USB-C cable, and boom, you have instant portable power. People carry power banks for the same reason remote freight drivers carry extra cans of gasoline: If the main supply runs out, there’s extra fuel on board.

Size and Capacity

Powerbanks are available in many sizes. The smallest power banks are small enough to fit on a key chain and typically will only deliver a quick hit of power per charge. The largest power banks in existence can charge EVs — but those aren’t exactly portable.

Generally, power bank capacity is measured in milliamps per hour — mAh. This unit indicates how many milliamps of electric current a given power bank can deliver per hour.

All smartphone manufacturers utilize different batteries and charging systems. The working capacity of any power bank entirely depends on the device it is charging. Most fully charged smartphones contain 3,000 to 4,000 mAh, That means, on paper, a 10,000 mAh power bank can recharge a smartphone about three times.

Most of the power banks on this list hold around 10,000 mAh — a standard size for recharging small devices like smartphones, Bluetooth headphones, and smartwatches. Though brands often claim their 10,000 mAh power banks can recharge smartphones five, six, or seven times — they rarely live up to those claims.

Smartphone batteries are becoming larger and more efficient. In our experience, 10,000 mAh power banks will charge a modern smartphone between two and three times. On this list, the Nitecore NB10000 is the most impressive 10k mAh power bank that we tested. It fully charged an iPhone 13 two and a half times.

If you are looking for a power bank for something like a long backpacking trip, it’s important to find an appropriate weight-to-capacity ratio for your adventure. You’ll also want one that fits comfortably in your backpacking backpack, and doesn’t add too much bulk to your kit.

Compact 10k power banks are rightfully popular. They fit easily into most s, and they have plenty of capacity to keep a small device or two alive for a few days.

The next standard portable power bank size is 20,000 mAh. Not all power banks in the 20k range will have a capacity of exactly 20,000 mAH — that’s just a handy benchmark figure. Naturally, 20k power banks are bigger and heavier than their 10k little siblings. Most 20k banks weigh at least one pound and are roughly the size of a small tablet or jumbo candy bar.

Though 20k power banks are a bit cumbersome for everyday carry, they offer much more utility. Most banks of this size can fully recharge a smartphone six or more times. Plus, many 20k power banks can charge multiple devices at the same time. If you’re looking for a power bank to charge multiple personal devices over the course of a multi-day backpacking trip, 20k is your best bet.

Power banks above 20k mAh start to get fairly heavy and less portable, but they’re great for folks looking to charge a larger device such as a laptop on the go. If you’re searching for a bank that can handle the demands of laptop charging, around 20k mAh is the bare minimum capacity you should consider. On this list, the Goal Zero Sherpa has an impressive capacity of 25,600 mAh. The Lion Trek is another excellent high-capacity power bank — and it even sports a standard three-prong AC outlet.

Charge Times and ‘Fast Charging’

The best power banks are quick to store power and equally quick to dispense it. Combined with the appropriate modern charging cable, all of the power banks on this list perform well in this aspect.

These days, many devices including phones, power banks, tablets, and cables claim to support “fast charging.” In reality, there is no universal standard for what “fast charging” really means. Each individual device has specifications that determine how much wattage delivery it can handle. Every element in the charging system — phone, power bank, and cable — plays a role in the rate of power delivery.

All batteries operate with a specific amount of voltage and can input and output a maximum amount of current. Fast-charging power banks have the ability to quickly pump more power into the receiving device.

For example, early iPhones came with a 5W power adaptor in the box. Those 5W adaptors took over two hours to charge standard smartphones. On this list, the speedy OtterBox Fast Charge delivers 18W power — it can fully charge an iPhone 13 in just over 90 minutes.

In general, any charging source that can deliver around 15w or more could be considered “fast charging.”

While fast charging is highly sought after, it can also be a detriment to your long-term battery health. Certain small devices such as headphones and fitness watches have relatively low maximum tolerable power delivery.

If you charge a pair of earbuds with a superpowered fast-charging wall port or power bank, it can cause irreversible damage to the battery life of those headphones. Many modern power banks — such as the OKZU C10002Y and the OtterBox Fast Charge — can decrease their output to meet the needs of a small device or fragile battery.

To choose the perfect power bank for your personal devices, check the device’s USB PD (power delivery) Power Range. For example, if a device’s USB PD Power range is 15-27W, pick a bank that delivers power within that range.

Types of In/Out Ports

Nearly all small electronic devices including smartphones, smartwatches, tablets, earbuds, headphones, and laptops charge via one of three standard input ports: Micro USB, USB-A, and USB-C.

Micro-USB ports are growing obsolete, but they’re still relatively common on power banks today. USB-A ports are typically used as outputs, though some small power banks such as the Goal Zero Flip 24 do have USB-A inputs, which eliminate the need for a charging cable.

The most common kind of input port is USB-C — the same port found on all modern iPhones. USB-C ports are easy-to-use, efficient, and durable.

Power banks only need a single input charging port, but it’s handy to have multiple types of output ports. On this list, the Lion Trek Power Bank has an impressive variety of outputs including USB-A, USB-C, and an AC outlet. Though it’s great to have plenty of output options, power bank users will mostly use USB-C ports.

Wireless Charging and Magnetic Power Banks

Some larger power banks are equipped with wireless charging capability. On this list, the Goal Zero Sherpa 100 PD comes with a wireless charging pad that can deliver up to 15w of power to compatible devices. In general, wireless charging from a power bank will be slower than using a cable, but it’s highly convenient in certain situations.

Some power banks attach directly to smartphones via magnetic connection. These power banks are compact units that typically pack just enough power to recharge a compatible smartphone a single time. On this list, the Hinovo Magnetic Charger is a highly functional and convenient option. It essentially doubles your phone’s battery — no cable required. Of course, only some smartphones are magnetic charging enabled.

Pass-Through Charging

If a power bank has “pass-through charging,” it is able to take in and distribute power at the same time. Pass-through equipped power banks can charge devices while plugged into a wall charger — a handy feature when you’re in a hurry. Many power banks on this list have pass-through charging, including our top pick the Nitecore NB10000.

Durability and Waterproofing

Depending on your needs, durability and waterproofing may be top priorities. If you plan to use your power bank for outdoor applications such as hunting, backpacking, and off-roading, we recommend that you pick one that’s built to withstand more rugged use. On this list, the Dark Energy Poseidon Pro 10200 is a rugged standout. It is waterproof, drop resistant, and immune to extreme temperatures.

Unlike the Poseidon Pro, most power banks aren’t built to withstand harsh treatment or exposure to the elements. For longevity’s sake, we recommend keeping your power bank relatively warm and fully dry. To preserve the integrity of the battery, power banks should be plugged in and charged once every few months.

FAQ

If treated properly, the power banks on this list should perform reliably for several years. All batteries degrade with time and regular use. Most modern power banks can be fully charged and discharged about 1,000 times before they no longer function. For most users, this equates to 3-5 years’ worth of use.

All of the power banks on this list are relatively small and portable. The majority of power bank users pick 10,000 mAh power banks, a good choice for recharging a personal smartphone. Compact 10,000 mAh power banks like the Nitecore NB 10000 offer a nice balance between utility and portability. They fit in a pant. and they pack enough power to keep a smartphone alive for several days without a wall outlet.

If you plan to charge larger devices like a tablet or laptop, we recommend sizing up to the 20,000 mAh range. These power banks typically weigh 1-2 pounds, and they’re still compact enough for hiking, traveling, etc. On this list, the Anker PowerCore III Elite has a strong battery that easily recharges a laptop — or multiple small devices at once.

Most small portable power banks can be carried onto an airplane. According to TSA, power banks cannot be kept in checked luggage. Certain airports don’t allow passengers to travel with more than 27,000 mAh in total battery storage.
