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.)

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.

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.

RAVPower 90W Power Delivery Portable Charger Charging Chromebook (Image credit: Ara Wagoner / Android Central)
Today’s phones and tablets are more powerful than ever, but despite more power-efficient processors, it’s not uncommon to find yourself needing to charge up at times when you aren’t near a wall outlet with a portable charger or power bank. A high-capacity battery pack that is 20,000mAh and higher is ideal for people who need a lot of juice while on the go, and while they may not fit into your. they’re necessary for keeping your devices topped off. Our top pick is the RAVPower 90W Power Delivery Portable Charger. Here’s why it’s the best high-capacity power bank, along with other great alternatives if you need something even bigger.
Reasons to avoid
Anker is one of the biggest names among power banks and chargers today. It’s built that name thanks to exemplary build quality and long-term durability and recently announced new technology to further improve on the best Anker power banks on the market. The Anker 737 Power Bank is a major upgrade from previous generations with 24,000mAh in a very compact package. But don’t mistake its small size for small power. It can pump out up to 140W of juice and recharge at the same rate. This means that this power bank can charge phones, tablets, and power-hungry laptops with no trouble.
24,000mAh is on the lower end of the high capacity spectrum, but it can still recharge a smartphone four to six times on a single charge or recharge most USB-C laptops from empty to full at least once. If you are using more than one port, it is worth keeping in mind that the USB-A port is capped at 18W regardless of what the USB-C port is doing. But those high-powered USB-C ports will still kick out up to 122W when using both simultaneously.
This beefy bundle isn’t lightweight, but nothing over 20,000mAh is. The Anker 737 Power Bank is compact enough to easily slip in and out of a backpack while rushing around an airport or convention. While it doesn’t come with a USB-C charger, it does include a high-quality USB-C to USB-C cable capable of handling the high wattage. You also get a helpful display showing battery percentage, what the output or input rate is and how long until the battery is drained or full.
Reasons to avoid
When it comes to charging multiple devices quickly with a power bank, you don’t need tons of ports, just a few ports that all charge at decent speeds. If you need a big, beefy battery that you can still fly with, the Sherpa 100PD is just under the FAA’s 100Whr limit, and it’s just what you need to keep a laptop or camera topped off while working on the road.
The main port here is a 60W USB-C Power Delivery Port, which will give your laptop a quick recharge and recharge faster once you reach your destination and plug it back in. You also get two USB-A ports for smaller peripherals and a Qi wireless charging pad on the top of the bank.
Goal Zero is a brand you might not have heard of before since it tends to deal with solar and portable power solutions. However, because it’s geared towards outdoor tech, you can rest assured this is a battery pack that will not leave you hanging. The Sherpa 100 PD is about half the size (and half the price) of the Sherpa 100 AC, so make sure you grab the newer PD model!

Let’s say that you want an overwhelmingly huge battery pack with no concern about its price or size. If that’s the situation you’re in, the MAXOAK Power Bank 50000 hits all the right notes.
The 50,000mAh capacity here is enormous, and while you may not think you need that much battery, it comes in handy for long road trips, hurricane season, and other situations in which you’re without access to power for a prolonged period of time. With such a big battery, you could charge an iPhone X up to 16 times.
For phones, tablets, and other mobile gadgets, you have two USB-A ports at 2.1A and two USB-A ports at 1A. MAXOAK’s battery pack is also a great choice for laptops, as there are 20V and 12V DC outputs.
MAXOAK’s pack won’t be going in your anytime soon, but you can easily toss it in a backpack and have hours upon hours of charge time to take with you anywhere.

Our editor Harish Jonnalagadda tests a lot of power banks, and two of his recent favorites are the Shargeek Storm 2 and Storm 2 Slim. He called the latter his new favorite because of its portability and 130W charging speed, but even though it could just make our list at 20,000 mAh, we’re more focused on high-capacity power banks here, so we’ll go with the standard Storm 2 for this list.
The Storm 2 has four ports, including a DC outlet with a variable voltage you can control via the built-in screen, which also shows ports in use, battery charge level, and thermals. As Harish noted, 25600mAh is just under the 27,000 maximum allowed on carry-on luggage, and the Storm 2’s 579g weight gives a pretty solid size-to-capacity ratio.
You can use up to three of the four ports at once; below is the breakdown of how much power you get per charge:
- USB-C1 USB-C2: 65W 30W
- USB-C1 USB-A: 65W 18W
- USB-C2 USB-A: 30W Max
- DC USB-C2: 65W 30W
- DC USB-A: 65W 18W
- USB-C1 USB-C2 USB-A: 65W 25W
- DC USB-C2 USB-A: 65W 25W
Perhaps the coolest thing about the Shargeek Storm 2, aside from its powerful wattage, is its transparent and distinct look, something techies will find pretty distinct from power banks’ usual look.

If you’ve played in the rugged power space for any amount of time, you’re bound to be familiar with Jackery and its eponymous Explorer Series. These power stations come in sizes ranging from 160Whr all the way up to 100Whr, but after reviewing the Explorer 300, we think it hits the sweet spot in Jackery’s current lineup for three reasons:
- The Explorer 300 has a USB-C Power Delivery port, while the 500 and 240 do not.
- You get both AC wall plugs and a car outlet, which many camping appliances runoff.
- 300Whr is a good capacity without getting super expensive or too heavy.
Unlike the RAVPower, Jackery goes for the traditional toolbox style where all the ports go on the front, and all the power cells sit in the bottom and back with a box, honking handle up top that’s easy to grab and easy to carry from a car to campsite and back again. There are two AC plugs here that can be used to charge electronics and run smaller appliances like a camp fridge or a TV, but it’s not rated for higher-wattage electronics like the Explorer 500 and 1000. When used with lower-wattage devices, it also has an automatic shutoff, meaning you can’t trust it to stay on all night with a CPAP machine.
Like Goal Zero, Jackery makes solar panels perfect for recharging this power station when you’re out in the woods for that three-week sabbatical, but also, like Goal Zero, those solar panels will come at a steep premium. If you need to recharge the Explorer 300 in a hurry, though, you can combine the 60W Power Delivery charging with the included 90W wall charger to recharge to 80% in two hours.

There are battery packs in a league of their own, and there’s the Fanttik Evo 300. Not everyone needs to spend this much money on a battery pack, but if you want one of the most powerful options out there and have the money to afford it, this is it, chief.
The Fanttik Evo 300 is less of a battery pack and more of a lunch box-sized emergency power station. You get plenty of ports and surge output up to 600W, which powers more substantial things through the AC outlet and car socket for a day or two.
Going back to the port selection, you have a lot to choose from, including:
- 12V DC car socket
- Two 110V AC output
- Two USB-A 3A ports
- Two USB-C ports, one rated at 60W PD
- DC input combines with USB-C for faster recharging
While it is on the expensive side and a bit cumbersome, the after reviewing the Fanttik Evo 300, it became clear it’s one of the best options for having a reliable power source during power outages, emergencies, and long camping treks. As an added point of comfort, the power station has a large LED room light to ensure you are never left in the dark, checking all of the boxes for why everyone should own a portable power station.

One of the best use cases for a power bank is using it as a power source while camping, hiking, or on other outdoor adventures. If this is the primary scenario in which you’ll be using your new power bank, we recommend checking out the BLAVOR Solar Charger Power Bank.
For people who spend a lot of time outdoors, one of the best features of this battery pack is solar panels on the top that allow it to recharge using the sun. Solar recharging isn’t the fastest, but it is nice to have. If you need to recharge the BLAVOR more quickly, you do so via USB-C or Micro-USB. This bank has a single USB-C 18W Power Delivery port, two USB-A ports (one 9V/2A, one Qualcomm QuickCharge 18W), and there’s even a 10W Qi wireless charging pad so that you can charge four devices at once.
An IPX5 rating offers ample protection against splashing water, there’s a built-in LED flashlight to help you see at night, and the 20,000mAh capacity should be plenty of battery for most weekend adventures.
Balancing size and sensibility: What makes the best high-capacity power banks
You’ll be happy no matter which battery packs on this list you choose, but at the end of the day, if you want a portable power bank that offers high-power output and isn’t going to be a beast to carry around, the Anker 737 Power Bank is the way to go. It allows you to charge three devices at once, it comes with a high-quality cable and has a helpful display to see the battery status. While this power bank isn’t going to come cheap, it offers impressive capabilities that will likely handle your mobile power for years to come.
We think the best value pick is the RAVPower 90W Power Delivery Portable Charger with its 30,000mAh capacity. It’s the most affordable entry on this list, and yet it also hosts one of the highest charging speeds and will still fit easily in your backpack or suitcase (so long as you aren’t getting on a plane). Yes, it only has two ports, but unless you consistently need to charge 3-4 devices at once, why pay for ports you on’t need?
How to choose the best high-capacity battery pack
While battery packs are seemingly simple gadgets, there are quite a few different things you should consider before buying one.
Sure, you could go out and buy the biggest one you see, but if you take the time to understand the little differences between everything, you’ll end up with a battery pack that truly fits your needs and works the best for your specific workflow/lifestyle. Once you have determined what you’ll be using the mobile power solution for, you can decide if a high-capacity power bank is for you or if you should go with one of the best portable power stations.
How much battery capacity do you actually need?
Perhaps the most important thing to consider before buying a battery pack is its capacity — in other words, how big of a battery it’s packing.
Since we’re dealing with high-capacity packs, we’re only looking at 20,000mAh or higher options. As such, any of the picks on this list will be able to charge your smartphone multiple times and still have some leftover fuel in the tank.
For comparison’s sake, most smartphones today have batteries that vary in capacity from around 3,500 and 4,500mAh. If you’re planning on using your battery pack to charge your phone, tablet, or headphones, something with a capacity of around 10,000-15,000mAh should be enough so long as you’re getting home to an outlet by the end of the day. If this sounds like a better fit for you, you might want to consider a more compact power bank.
So, why do power banks with capacities of 30,000mAh and more exist? There are a couple of good reasons:
- For people that want to charge a larger device, such as a laptop, having a big capacity will ensure you have access to enough power.
- For backpacking or other outdoor adventures where outlets are few and far between, a high-capacity bank ensures you can keep your phone charged and your lifeline alive, as well as power small camping appliances.
- If you live somewhere prone to severe weather like hurricanes or tornadoes, a power station-style high-capacity portable charger like the Anker 757 PowerHouse will ensure you can stay connected while waiting for the electrical grid to be repaired. That also applies to whether you experience a serious personal emergency like a house fire.
Why USB-C is so important
We’ve talked a lot about USB-C Power Delivery throughout this article, but let’s take a step back for a second and explain why it’s so important and why you should get a USB-C battery pack.
USB-C is essentially the better-in-every-way evolution from those Micro-USB ports that used to be prevalent on just about every Android phone for charging. Not only does USB-C benefit from the fact that it’s reversible (meaning there’s no wrong way to insert it), but it’s also considerably more powerful: Power Delivery can be used to charge at speeds up to 100W or beyond, such as the 140W speeds on our overall pick, the Anker 737 Power Bank.
Here’s the thing, though — not all USB-C ports are created equally. Most USB-C ports come with the Power Delivery standard (often referred to as PD), which signifies that a USB-C port offers considerably faster charging and data speeds. So if a USB-C port only offers 15W, that’s a USB-C port that is not USB-C, and you should skip it.
As such, when you’re looking to charge a device that has an extraordinarily big battery, not just USB-C but also Power Delivery is a must. Not only are a lot of newer devices moving to Power Delivery ports, but it’ll also cut down quite a bit on recharge times.
How to Use a Power Bank: Here’s Everything You Need to Know
You know that anxious feeling when the “low battery” notification pops up on your screen? There’s something about it that can send your mind into a tailspin. Even worse, sometimes you don’t have your charger, and you’re nowhere near an outlet! Luckily, there’s a handy tool out there to keep you fully charged: the power bank. If you’re looking to learn the basics of power banks, you’ve come to the right place. Let’s get right into it!
How to Charge a Power Bank Top
Charging a power bank is pretty straightforward, especially since most of them come with instruction manuals. However, if yours didn’t come with one, you can still charge it without breaking a sweat!
Here is the best way to charge a power bank:
- Attach the cable to the power bank.
- Connect the other side of the cable to your power source.
- Your power bank should begin charging.
- Once charged, unplug the power bank from the wall and your phone.
- Step 1: Attach the Cable Attach the cable that came with your power bank to the device itself. Most of the time, the port that connects to your power bank is a micro USB.
- Step 2: Plug Into Power Source Next, plug in the other side of the cable (usually a standard USB) into your wall plug or your computer. Some wall outlets even have USB ports built in, so if you have one of those nearby, you won’t need a wall adapter!
- Step 3: Start Charging Your power bank should start charging. If it has an indicator light, keep a close eye on it. Once it is fully charged, all the indicator lights will illuminate.
- Step 4: Unplug the Charger Unplug the charger from the wall or your computer once all indicator lights are illuminated.
How Often Should You Charge a Power Bank? Top
A general rule of thumb is that the more you charge your power bank, the shorter the lifespan of the device. You should charge your power bank only as often as is necessary. If you use your power bank sparingly, at least charge it once every 3 months to keep the battery active.
Can I Use My Phone While Charging? Top
There shouldn’t be any harm in using your cell phone while it is charging. You may notice your phone getting a bit warm, but this is expected. It’s worth noting, however, that using your phone while it is charging may not result in a 100% charged battery since you are actively using the power source before the charge is complete. If you want your cell phone to be fully charged, it’s best to leave it alone while it powers up!
Why Do Some Power Banks Take Longer to Charge? Top
Some power banks take longer to charge because larger batteries have a bigger capacity to store energy. For example, a high capacity power bank with 20,000 mAh can take up to 40 hours to charge fully. Smaller power banks with 4,000 mAh may only take a couple hours to charge.
Think of it like a shot glass versus a tall drinking glass. It’s going to take a lot longer for a drinking glass to fill with water than it will for the shot glass!
How Long Should You Charge a Power Bank? Top
You should only charge your power bank for the amount of time it takes for it to get a full battery. Once the device is fully charged, you should unplug it from the power source. You can check the user manual to find out how your power bank indicates it has been fully charged, but most of them have some sort of light that shows the amount of power left in the battery.
The amount of time it takes for a power bank to reach its full capacity varies depending on the type. A heavy-duty power bank will take longer to charge than a smaller one. Generally speaking, it takes between 1 to 2 hours for a power bank to become fully charged!
Did You Know?
There are super powerful power banks on the market that allow you to power larger devices like televisions, curling irons, and oscillating fans!
Can I Charge My Power Bank Overnight? Top
You should avoid charging your power bank overnight whenever possible. It is unlikely to cause significant damage, but there is still a chance it could reduce the lifespan of your battery over time.
For lower-quality power banks, leaving your power bank plugged in after it is fully charged can cause overheating, especially if they are left to charge in direct sunlight. The safest option is to always unplug your power bank once it has reached full capacity!
How Can You Make Your Phone Charge Faster? Top
If you ever find yourself in need of a quick battery charge for your smartphone, there are a few steps you can take to make your phone charge faster. Always make sure your charging cables are plugged all the way in and your power bank has enough power to charge your phone.
Here are some tips to make your phone charge faster:
- Turn on airplane mode
- Don’t use your phone while charging
- Turn your phone off
- Use a high-capacity power bank
- Don’t use a wireless charger
Turn on Airplane Mode
Putting your phone on airplane mode is a surefire way to reduce charging time. This is because the setting turns off your phone’s Wi-Fi, Bluetooth, and cellular capabilities, which are all settings that drain your power! When your device is on airplane mode, it’s consuming less power, which makes for a quicker charge.
Don’t Use Your Phone While Charging
Using your phone while it’s charging is going to increase the amount of time it takes for your battery to be fully powered. It may be difficult to resist the urge to send that text message or check Instagram, but it’s worth the sacrifice if you want your phone to be fully charged!
Turn Your Phone Off
This strategy works similar to airplane mode because it turns off all the components in your phone that would otherwise be using your battery. When your phone is powered off, it’s able to reach a full charge much faster. Keeping your phone on while it’s charging is like trying to sleep while you’re hungry or thirsty—it’s going to be much more difficult!
Use a High-Capacity Power Bank
Some power banks are more powerful than others. The heavy-duty ones are going to make your phone charge much faster than the smaller ones! However, not all phones can handle a high-powered portable charger. It’s best to contact the manufacturer of your cell phone to see what they recommend. Charging your battery with too much power is never a good idea!
Don’t Use a Wireless Charger
Wireless chargers are a genius invention, but they’re not the best option if your goal is to charge your phone quickly. Plugging your phone in directly to a power bank or outlet is the quickest way to bring it back to life because it’s directly connected to the power source!
At the end of the day, any way you can prevent your phone from using battery while charging will ultimately help it charge faster! You might also notice your phone charging slowly with a low-capacity power bank. Be sure that your phone and power bank are compatible for the most efficient charging.
How Long Do Power Banks Last? Top
The amount of time a power bank lasts varies from product to product, but on average, a power bank should last at least a couple hundred charging cycles.
If you use your power bank frequently, you’re going to consume more charging cycles than someone who only uses their power bank occasionally. There are more durable power banks out there than can last upwards of 1,000 charging cycles, but most of the smaller ones on the market have a lifespan of 200 or 300 cycles. The age of the power bank also has a significant impact on how long it lasts. As the batteries inside of the device age, they become less effective.
How to Store a Power Bank Top
Power banks should always be stored in a cool location that isn’t exposed to direct sunlight, such as a desk drawer. According to Battery University, batteries achieve optimum service life if used at 68 degrees Fahrenheit, or slightly below that temperature.
If you store your power bank in direct sunlight or a warm environment like the glove box in your car, it won’t last as long. It’s also best to store your power bank in a pouch or case when not in use. This helps protect the charging ports so they do not accumulate dust or debris!
Should You Buy a Power Bank? Top
If you’re always on the go or find yourself with a low battery, you should buy a power bank! They come in handy during vacations, trade shows, plane rides, or any time you are using your phone away from an outlet. The type of power bank you’ll need depends on your lifestyle and how many devices you need to charge.
There’s no reason to not invest in a power bank. They’re like an extra insurance policy for your phone’s battery! Having one with you just in case is always a good idea.
The Bottom Line
Power banks make our lives a bit easier by ensuring we never run out of juice. By using them properly, you’re not only protecting the power bank, but you’re also getting the most out of your investment! A properly cared-for power bank will get you through those long meetings and plane rides. Just think of all the adventures you’ll go on while still having peace of mind!
