Best Anker power banks: top 5 picks in 2022. Anker charger power bank

The Best Power Banks of 2023, Tested and Reviewed

If I have the choice between a device that uses conventional batteries or one that uses rechargeable batteries, I’ll always go with rechargeable. But that means I need to maintain that device, which is why a portable power bank comes with me on nearly every trip. Over the past month, I’ve tested a dozen of the top rated power banks, and from that initial pool, I’ve narrowed it down to the six best power banks.

It doesn’t matter if I’m spending time outdoors or traveling, I’ll need to recharge something, and will inevitably use a power bank. My picks for the best power banks have been used while in the outdoors as well as for everyday use and holiday travel. They’ve juiced up headlamps, GoPros, my iPhone, and even other power banks. After all that field testing, here are my findings and recommendations for the best power banks.

  • Best Overall:Anker PowerCore Slim 10,000 mAh
  • Best Solar:BigBlue 28-Watt Solar Charger
  • Best for Fishing:Anker Solar
  • Best Small:Goal Zero Flip 12
  • Best for Backpacking:Anker PowerCore Essential 20,000 mAh
  • Best for iPhones:Anker Powercore Magnetic 5K

How I Tested the Power Banks

I tested the power banks in three ways: First, I timed how long it takes them to fully charge and how many times they fully charged my iPhone 11 Max. Then over a one-month period I carried these portable chargers during outdoor activities in several states, on long road trips, and a fishing trip in North Carolina. During that month I subjected them to heat, cold, and water to test their durability. Finally, I weighed and measured each power bank to provide you with accurate specs.

Here are the attributes I used to evaluate the power banks:

  • As advertised (Do the chargers do what the manufacturer advertises?)
  • Number of charges and charge time (How many times does it charge a phone? How long does it take to charge?)
  • Use in the field (Is it practical to use while hunting, fishing, camping, hiking or backpacking?)
  • Durability (Can it hold up to abuse?)
  • Weight (Ounces are pounds, and pounds are pain.)

Best Overall: Anker PowerCore Slim 10,000 mAh

Key Features

  • 10,000 mAh
  • 3-hour charge time
  • Charges an iPhone twice
  • One USB port
  • Micro USB and USB-C input
  • Weight: 8.4 ounces
  • Length: 6 inches
  • Width: 2.75 inches
  • Depth:.5 inch

Product Overview

If you’re looking for an all-around solution, consider the PowerCore 10,000 mAh. It’s a happy medium between a small charger like the Goal Zero Flip 12 and the PowerCore 20,000 mAh. If you are going out for the day or an overnight trip, it provides plenty of juice with two phone charges. It’s also light and small enough to not take up space in a pack or

The Anker PowerCore went through three key tests: a timed charge, testing how many times it would charge my iPhone 11 Pro Max, and using the power bank in the field. One of my favorite features of this power bank is how fast it charges. In a few hours, you can bring it from dead to fully juiced and ready to hit the field. It’s fast charging ability also makes it an excellent candidate to pair with a solar panel like the BigBlue 24 watt.

In my testing, the Anker PowerCore charged my phone twice. That’s two times with the phone on and in use. So, if you keep your phone off while it’s charging, you can expect the power bank to last longer—Anker rates it at two-and-a-quarter iPhone 12 charges. I most often use this charger when I’m going to be out all day and will need to charge my phone once, along with another device like a GoPro. It would also be ideal for a two-to.three day camping trip where you need to charge your phone twice.

The Anker PowerCore is slim and light enough that you can carry it in a for everyday carry. It’s also perfect for carrying in a daypack or sling bag. Mine has been with me hunting, fishing, and traveling—it’s yet to let me down.

Best Solar: BigBlue 28-Watt Solar Charger

Key Features

  • 25 Watt
  • 3 USB ports
  • Charges a phone in about 3 hours of full sun
  • Charges a 10,000 mAh power bank in 6 hours
  • Weight: 1 pound 9 ounces
  • Length: 11.125 inches
  • Width: 6 inches
  • Depth: 1.375 inches
  • Size

Product Overview

There are a lot of portable solar chargers on the market, and they range in price as much as they do in effectiveness. The BigBlue is the best solar power charger that actually works and it’s affordable. You have to manage your expectations when it comes to these small solar panels and while three hours to bring a phone to full charge seems like a lot, I think it’s pretty impressive.

Here’s the context of my testing. I tested this solar panel in the fall when the sun sits low in the sky. The first hour of the charge the panel received partial sun. I managed the position of the panel throughout the day to keep it aligned with the sun.

The first test was to see how long it took to charge a Goal Zero Flip 12, which is good for one full phone charge. That test took three hours, which is how long it takes to charge the Flip 12 when plugged into the wall. The next test was to see how long it takes to charge my pick for the best power bank, the PowerCore 10,000 mAh. After six hours in the sun the power bank was at full power.

When you’re in the field, you probably don’t have time to sit around for six hours waiting for a power bank to charge. But, that’s not the best way to use this charger. In my opinion, using the solar panel to maintain battery life rather than fully charge a device is the best use. For example, if you are glassing in the morning, you can roll out your solar charger and plug in a device. Let’s say you stay put for just an hour, that’s enough time to charge a phone 30 percent. By charging your devices a little at a time throughout your time in the field you can make your powerbank or batteries last much longer.

Best for Fishing: Anker Solar

  • Water resistant
  • Solar charging
  • 20,000 mAh
  • Two USB ports
  • One USB-C port
  • Needs to be charged overnight
  • Charges a phone four times
  • Weight: 1 pound
  • Length: 6.875 inches
  • Width: 3.625 inches

Product Description

I used the Anker Solar on a few upland bird hunting trips and a trip chasing false albacore in North Carolina making this the best power bank for fishing. While chasing albies, we had one bad weather day with a lot of chop. If I wasn’t wearing a rain suit, I would have been drenched. The Anker Solar was subjected to the same salt spray and it handled it just fine. It also had plenty of power to keep my phone, and GoPros fully charged during the ten hours of fishing. After I got off the boat, I grabbed a quick dinner before heading out on kayaks for fishing dock lights at night. That few hours wasn’t enough time to get the Anker Solar back to even half charge, which is the main downside.

If you plan to use this charger for backpacking or hunting, the weight and bulk are something to consider. The Anker PowerCore 20,000 mAh is considerably lighter and smaller, but it lacks the solar charging and weather protection the Anker Solar offers. Personally, I’d rather take the PowerCore for those applications, and think the Solar shines for fishing applications.

One of the questions you probably have is: does the solar panel on this powerbank work? If you plan to use the solar panel to fully charge your power bank, you’ll be waiting a while. I tested the solar charging capabilities by placing the power bank in full sun for six hours and did not see a measurable difference in charge. However, I think if you keep this charger in the sun all day, the battery will last longer than if you didn’t have the solar panel. So, consider it more of a battery extender, rather than a charger like the BigBlue.

Best Small: Goal Zero Flip 12

Key Features

  • 3,350 mAh
  • One USB port
  • One full phone charge
  • Three-hour charge time
  • Weight: 2.6 ounces
  • Length: 3.75 inches
  • Width:.625 inch
  • Depth:.625 inch

Why it Made the Cut

This power bank weighs nothing, has a small footprint, and has enough juice to completely charge your phone.

Product Description

This Goal Zero small power bank won’t take up space in your pack and has enough juice to bring your phone from dead to fully charged. For overnight or day trips, it’s my top choice. I also like keeping this best small charger in my carry-on to keep my phone charged while traveling.

The biggest con is that its square shape makes it uncomfortable to carry in a front But, it’s at home in a cargo. fanny pack, or day pack. My favorite features of the Flip 12 are it charges quickly and it doesn’t need a charging cable—the USB is built in. I also think it’s a great companion to a solar panel like the BigBlue.

Best for Backpacking: Anker PowerCore Essential 20,000 mAh

Key Features

  • 20,000 mAh
  • Up to five phone charges
  • USB-C and Micro USB input
  • Two USB output ports
  • 11 hours to fully charge the power bank
  • Weight: 12 ounces
  • Length: 6.25 inches
  • Width: 2.875 inches
  • Depth:.5 inch

Product Description

This is a power house for charging devices. Whether you’re on a short trip where you need to charge a bunch of devices or a long trip where you need to just keep a phone juiced, this is the best power bank. It weighs less than a pound and it’s easy to carry thanks to its slim profile and beveled corners.

The biggest con of the 20,000 mAh PowerCore is it takes a long time to fully charge. But, the negatives end there. The two USB ports allow you to simultaneously charge two devices. I used it to charge my phone and headlamp each night during a weekend outing. During a November fishing trip, I left the 20,000 mAh PowerCore outside in freezing temperatures. The power bank didn’t lose a bit of charge, which has been my experience with all my Anker power banks in cold weather. Granted, my cold weather in Virginia is different from Fairbanks, Alaska’s cold weather.

Best for iPhones: Anker Powercore Magnetic 5K

Key Features

  • Wireless charging
  • USC-C output and input
  • 5,000 mAh
  • Charges in three hours
  • Charges a phone once
  • Magnetic charging works with iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max
  • Weight: 4.6 ounces
  • Length: 3.625 inches
  • Width: 2.437 inches
  • Depth:.625 inch

Product Description

The PowerCore Magnetic 5K is a great size for everyday carry. It’s super lightweight and charges a phone fast using a USB-C charger. But, don’t buy this charger unless you have an iPhone, preferably a 12 variant, and a compatible magnetic case. If you don’t have a compatible magnetic case, you’ll have to remove your case to use the magnetic feature and you’ll be disappointed in the strength of the magnet.

But, if you do invest in a magnetic case, it’s a great wireless charger for outdoors use. Other wireless chargers aren’t practical for outdoor use because they need to be laid flat to maintain contact with your phone. But, the magnetic power bank from Anker snaps to your phone and stays connected even in a cargo or your best backpack. You get the benefit of not needing to bring a charging cable and a continuous charge while you use your phone. I find this charger is ideal for all day sits, or days when I’m running OnX continuously.

How to Choose a Power Bank

Power banks are a lot like other outdoor gear, there’s a trade off between features and weight. You can get more capability, but you’ll pay for it in size and weight. You’ll have to decide how much capability you need and how much weight you’re willing to carry.

Here are more things you’ll need to consider when buying a power bank or solar charger.

What is a mAh and how much do I need?

A spec you’ll often see is mAh, which stands for milliamps hour. The mAh spec is a measurement of power over time, the higher the mAh the more power the battery contains. To fully charge a phone you’ll need 3,000 to 5,000 mAh.

Watts

A watt is a measurement of rate of energy transfer. So, when shopping for portable solar chargers keep in mind that the more wattage the more power the panel can provide. I’d recommend at least a 24-watt solar charger.

Are solar chargers practical?

If you’re in an area where you can provide a solar charger full sun, and leave it all day to charge a power bank or device, they are practical. But, you can’t expect a solar charger that fits in your to work well because you need surface area to effectively charge.

I found small solar panels to work best for maintaining battery life, rather than being used to fully charge a device. The main issue is that portable solar panels are small, and can only gather so much electricity. What they can do is lengthen your phone or power bank’s life. When you stop to glass or cook lunch, lay out your panel and let it charge the device for a few hours. Even if it’s a few percent increase in battery life, it’s free energy and a few percent here and there can add up over a week’s trip. If you get an extra 25 percent out of our powerbank I count that as a win.

Solar panels are also bulky and heavy. For example, the BigBlue weighs 1.5 pounds, and the 20,000 mAh PowerCore weighs less than a pound. You can pack two 20,000 mAh charges that would charge a phone ten times total and weigh the same as a BigBlue.

Waterproof power banks

Why didn’t I include any waterproof power banks? The rugged power banks that are fully waterproof and shock resistant come at the penalty of being heavy and bulky for the amount of power they provide. I’d much rather drop my power bank in a dry bag than carry the extra weight of a waterproof power bank. It’s also worth pointing out that while your waterproof power bank might survive a submersion, your phone won’t.

Best Anker power banks: top 5 picks in 2022

Having a good portable power bank could make the difference between getting the call for that dream job and not; between binge-watching your favorite Netflix series during a long flight and staring at the seat in front of you; between conveniently navigating your way through a foreign country and having to gasp ask people for directions.

In other words, having a phone with a dead battery is not fun. Thankfully, we have power banks – an essential accessory for anyone who spends lots of time out and about… or just likes to use their phone snuggled in bed even while it’s charging. And Anker is the company making some of the best power banks on the market.

But what is the best power bank for you? How do you pick one and how do you make sense of all the technical specifications attached to every different model? Worry not as we’re here to help!

  • Anker 737 Power Bank – best overall
  • Anker 733 Power Bank – 2-in-1 wall charger and power bank
  • Anker 525 Power Bank – a more compact solution
  • Anker 633 Magnetic Battery – wireless, for iPhones with MagSafe
  • Anker 511 Power Bank – compact and lightweight

With all that being said, we’ve compiled here a list of the best Anker power banks to help you choose which one to get for yourself.

Anker 737 Power Bank

The Anker 737 Power Bank is the first one on our list for a reason: it has a huge 24,000mAh battery capacity and on top of that, it allows you to charge three devices simultaneously. The generous 24,000 mAh battery can charge an iPhone 13 completely almost 5 times, a Galaxy S22 – 4 times and a half, or can even charge 1.3 times a MacBook Air with M1 from 2020! That’s an epic amount of battery life you can carry around in a relatively compact form.

But that’s not all this power bank has going for it. It features a Smart Display which shows you important metrics like how much battery it has left, how much time it has until it’s charged, as well as other useful metrics such as Battery Health and battery cycles. If you need ultra-fast charging, you’ll be delighted to learn that the Anker 737 supports 140W fast charging (your device should support that, keep in mind), which can charge a MacBook Pro 16-inch to 50% in just 40 minutes.

Anker 737 Power Bank (PowerCore 24K)

Featuring a 24,000mAh battery capacity: charge up iPhone 13 almost 5 times or a 2021 iPad Pro 12.9 1.3 times.

Anker 733 Power Bank

Another great power bank from the Series 7 power banks by Anker is the 733. It has a 2-in-1 design and can be used as a fast charger when connected to a wall outlet, or as a 10,000mAh battery bank when you’re on the go. And, on top of that, you don’t need a separate power brick to charge the power bank itself! Additionally, it is widely compatible with iPhones, Samsung Galaxy phones, Pixels, and other devices, and can charge 3 devices simultaneously.

And, on top of all of this, the Anker 733 Power Bank features Active Shield 2.0, which ensures there won’t be any issues with temperature: it monitors temperature daily 3,000,000 times! An epic power bank, we might add!

Anker 733 Power Bank: get 15% off now until November 15

65W power bank that can also be used as a wall charger. You can charge 3 devices simultaneously. Right now, until November 15, you can get 15% off using code ANKER1111 (apply it in the cart).

Anker 525 Power Bank

If you need a more compact solution, the Anker 525 is a great option. It still has a 20,000mAh battery, so it’s quite capable of delivering enough battery for your phone despite being a more compact option than the ones we listed above.

It may be an older model, but its reliability and compact design are why it is listed as a part of the best Anker power banks that you can get right now. It has a 20W USB-C port which can fast-charge your iPhone, and it also features an 18W USB port for when you need to charge a second device.

Anker 525 Power Bank (PowerCore 20K): save 18

A more compact solution with 20,000mAh. 20W USB-C port to fast-charge your iPhone, and an 18W USB port for a second device. Right now, Anker has a great deal on it and you can save 18 with code WS7DQUI047.

Anker 633 Magnetic Battery

If you’re looking for something different than your standard power bank, the Anker 633 Magnetic Battery is one option to look into. However, keep in mind that you can take advantage of its magnetic capabilities only with an iPhone, which supports MagSafe, such as an iPhone 12 and above. It has a 10,000mAh battery and uses magnets to attach to your iPhone – and charges it wirelessly.

On top of that, it has a built-in kickstand so you can charge your phone and place it in a way that’s easy-to-view – on a table, for example. And, last but not least, it sports a compact and trendy design with multiple color options to choose from.

Anker 511 Power Bank

For an ultra-compact and lightweight solution, we have the 5,000mAh Anker 511 Power Bank. It is relatively smaller, and despite having a bit less in terms of battery capacity, it entices with its compactness. For a little (but much-needed) battery life, the Anker 511 Power Bank is more than enough. And, it is a cheaper solution in case you’re on a budget.

But that’s not all this power bank has going for it. It also has built-in prongs that you can use to plug it into a wall outlet and use it as a charger.

How to choose the best Anker power bank for you

Choosing the best Anker power bank for you is a process that requires you to take into account several aspects:

  • How often do you plan to carry it?
  • How much mAh do you really need?
  • Do you need the power bank to be able to charge simultaneously more than one device?

Let’s address why those (and similar questions to ask yourself) are important. First off, some Anker power banks can be quite heavy (bigger battery capacity, or mAh, means heavier power bank), so if you’re the type of person to carry around a lot of stuff, you should take into consideration the added bulk and weight.

Additionally, you should think do you really need to charge simultaneously three devices, or do you need it only for your phone? Basically, if a power bank can charge more devices at the same time, it will have more ports – and this can make it more expensive. Think about how many ports you need exactly and, if you need it just for your phone, you can go for a solution that has only one port.

On the other hand, the mAh is important to be able to figure out how many charges you will be carrying with the power bank. Each power bank has its battery capacity listed in the specs. The higher the number, the more juice it can store. For example, a more unassuming option (like the 5,000mAh Anker 511) will be able to charge your phone completely just once or one and a half times, depending on your phone’s battery capacity, while big solutions (like 24,000mAh ones) will offer several charges, needed for people with a more busy schedule and more time outside (and heavier phone use when out!).

How we pick the best Anker power bank

The power banks that we listed here are picked across a wide Anker portfolio in order to answer most people’s needs. We’ve selected all-out Anker power banks for busy people and people who need to charge more devices, like phones and smartwatches, simultaneously on the go. But that’s not all – we’ve also thought about people who use their phone less often and would like to just have a piece of mind when out and about so that they won’t run out of battery.

That’s why we’ve picked the best power banks for both use cases. We’ve also taken into account the bulkiness, the extras, the price (for what you get) and even the looks.

Do Anker power banks work with both Android and iPhone devices?

Anker power banks are famous for offering wide compatibility with different devices. All the power banks here (except the MagSafe wireless one) are compatible with Android phones and iPhones. Of course, you need to have a cable with the respective connector to charge your iPhone or Android phone. Most of the power banks listed here come without a cable for your phone, so do check that in the What you get section on Anker’s website for the power bank you have in mind.

On top of that, many of the solutions Anker offers can also charge tablets and, some of them, even laptops.

Are Anker power banks safe for my phones?

Yes. Anker takes safety seriously and virtually all its charging products are equipped with a technology called MultiProtect, which monitors voltages to ensure your devices and you are protected and safe. Additionally, the more expensive power banks we’ve selected include the ActiveShield 2 technology, which also monitors the temperature to prevent overheating when charging. You can read more about Anker’s MultiProtect here.

The Best Portable Chargers and Power Banks for 2023

Who It’s For

If you spend a lot of time outdoors, this is among your best choices for keeping your devices running while off of the grid. In other words, it’s camping approved.

What Size Battery Do You Need?

On the.friendly front, most smaller batteries have a capacity of around 5,000mAh, which is typically enough to top up most phones once.

Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery.

Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide (Opens in a new window) that can give you an estimate.

In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty.

What’s the Difference Between Power Input and Output?

You’ll find three types of ports on today’s portable batteries:

Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB.

Nearly all batteries include a standard USB-A port (output). This is for plugging in USB-A-to-micro-USB, USB-A-to-Lightning, or USB-A-to-USB-C cables for charging your iPhone or Android device.

Some batteries include built-in output cables and these generally have micro USB, USB-C, or Lightning connectors.

The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables.

Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common.

If you picked up an iPhone 13 or iPhone 14 and were surprised by the lack of an included wall charger, see our article on charging your iPhone.

What Is Fast Charging?

Another factor to consider is how quickly a power bank can charge your device. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity that flows from the battery to the connected device, while voltage is the amount of potential energy. Multiplying volts by amps gives you wattage, the measure of total power. To make devices charge faster, most manufacturers either vary the voltage or boost the amperage.

Today’s devices support a wide range of Rapid-charging technology, such as Qualcomm QuickCharge, USB Power Delivery, or proprietary fast-charge systems.

Quick Charge works by increasing voltage rather than amperage. This standard typically allows you to charge supported phones to 50 percent capacity in 30 minutes, which is especially helpful when you need power in a pinch.

Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways.

The most common devices (Apple iPhones and Samsung Galaxies) support charging rates of 27W and 45W, respectively. It’s best to look for batteries that can support charging in that range.

Is Pass-Through Charging Safe and Useful?

Pass-through charging is another feature to consider; with it, you can charge devices and the portable power bank simultaneously. That’s convenient if both your phone and backup battery are running on empty. You shouldn’t encounter any safety issues if the manufacturer of the portable battery you buy advertises pass-through charging as a feature, but the power output might change in this mode.

How Does Wireless Charging Work?

Wireless charging has become popular because it allows you to power up compatible devices without a cable. Qi is the dominant standard for compatible Android phones (up to 18W) while Apple iPhones rely on MagSafe charging (up to 15W). iPhones will charge wirelessly on Qi chargers, but only at 7.5W.

Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home.

Should You Buy a Battery Case Instead of a Power Bank?

If you find that you often forget to carry your backup battery when you need it most, you should consider a dedicated battery case instead. These combine the portability and protection of a case with additional battery capacity to keep your phone topped off at all times.

There are several drawbacks. First, they have limited additional capacity on board. Second, they are limited in terms of the number of phones they support (mostly just iPhones, Galaxies, and Pixels). Third, you can’t charge much else with them.

The Best Wireless Chargers

Why fumble around for a charging cable when you can rest your phone on a wireless charging pad? Whether you’re an Android user or an iPhone fan, check out our roundups of the best wireless chargers and the best MagSafe chargers to help you cut the cord.

Amazon just dropped a huge sale on Anker charging accessories — save as much as 60%

A cellphone that’s on 1% while you’re stuck in traffic. A tablet that runs out of juice during a long and dreary commute. A laptop that decides to die while you’re trying to get work done on the go. These are all unpleasant scenarios that teach you never to leave home without a spare charger. Luckily, you can save up to 60% right now on select Anker charging accessories — including lightweight power banks, durable cords and more.

Anker 321 Power Bank (PowerCore 5K)

This compact power bank is perfect for keeping in a bag for an emergency charge — and even better, it’s 25% off.

I don’t know how many people have this same issue, but its always a battle for me to get daughters (ages 20 22) to take power banks with them when they go on their adventures (travel, concerts, etc.). I have at least 10 Anker power banks (including all of the latest). But I can’t get them to take of them with them because they are too big. They wont take either of the two MagSafe chargers i have either because although small, it means they have to remove their MagSafe wallets. But this one is finally small enough that now I win that debate! said one parent. So that peace of mind alone gets a five star rating from me! And because it’s an Anker, I don’t have the same fears I would have from any of the no name small chargers. So it’s only good for 1 charge for an iPhone 12, but that a lot better than zero. For me, that’s the whole point of this.

Anker 626 Magnetic Battery (Blue)

The kickstand with battery connects magnetically to your phone so that it stays charged and at the perfect viewing angle.

With enough juice to give almost a second full charge, this magnetic battery snaps securely to your phone and doubles as a stand. Keep your phone at the perfect viewing angle and within easy reach while it charges. It comes with a 24-month warranty to cover any potential damage. In addition to purple (shown), it’s also on sale in blue and white.

Love the color! Love the size! Love the power it has! Have I said I love this charger? one ecstatic customer said.

Anker 100W USB-C 2-Port Charger for MacBook Pro/Air

This charger is meant for MacBooks, but it will work with almost any device. And right now, it’s nearly 60% off, which makes it a fantastic deal — especially if you’ve ever looked at the price of a replacement Mac charger.

I really like this charger because it is so powerful. I can use my laptop and charge my S22 Ultra in record time. It has a nice solid feel to it. Foldable plug to slip easily into a backpack or laptop bag, said one on-the-go user. I wish it was a little smaller for traveling, but I imagine that is the price you pay for having 100 watts of power. I own many Anker products and this does not disappoint.

Anker Portable Charger

This 10,000mAh power bank can charge your phone from zero to full at least once and, depending on the model, sometimes twice.

This handy Anker Portable Charger is compatible with most modern devices and provides an extra 10,000mAh of charge. That equates to basically a full charge for your phone. An iPhone 12 can actually get two full charges, but newer devices with higher power requirements may only get one. Still, that’s a full charge without being tied to an outlet.

This charger is the answer for a quick, portable and reasonably sized charger. Great for traveling, at the beach or anywhere that an accessible method for charging is unavailable, one user said. The size is comparable to most cell phones and is perfect in a. backpack or purse. Comes with a mesh carry bag, a USB-C to USB-C cord along with a USB-C to USB cord.

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of 25 or more.)
