I hate running out of power. Everybody does. While our gadgets have advanced in many ways, battery technology has been slow to improve. That’s why you’re looking to buy a power bank. A good portable charger is a handy backup that can keep your smartphone, tablet, and maybe even your laptop going for longer. I’ve been testing power banks for many years. I’ve tested more than 100 portable chargers. But you only really need one or two.

Most folks should buy one of the first four power banks I recommend, but there are a few other unique use cases, so I’ve included a few extra options. Read the Best MagSafe/Qi2 Power Banks for more magnetic wireless chargers, and Best Laptop Power Banks or Best Portable Power Stations for more power.

Updated May 2026: I added a power bank from BMX, more details about capacity, a new FAQ section on charging slowly, removed some older devices, and updated prices.

Don't Bother With These Power Banks

These portable chargers I tested aren't necessarily terrible, but you can do better.

Image may contain Computer Electronics Laptop Pc Computer Hardware Hardware Mobile Phone and PhonePhotograph: Simon Hill

OnePlus Slim Magnetic Power Bank for $28: Sleek in silver-gray aluminum with a chamfered edge, this power bank looks lovely, but the 5,000-mAh capacity is just over half that after inefficiency takes a bite.

Iniu Portable Charger for $22: It's very small for a 10,000-mAh capacity. You can charge at up to 45 watts from either of the USB-C ports or 18 watts from the USB-A, but recharging is slow, it fell short of the stated capacity, and the display sometimes failed to update correctly.

FansDreams MChaos for $46: I love the idea of a wearable power bank, and this one comes in lime green with a carabiner that makes it easy to attach to a bag, but recharging is slow, and you’ll be lucky to get one full charge for your phone.

iWalk Portable Charger for $27: The 4,800-mAh capacity won't come close to fully refilling your device, but it's tiny enough to keep in a bag at all times.

What Features Should I Look for in Power Banks?

AccordionItemContainerButtonLargeChevron

There are a few things worth thinking about when you’re shopping for a portable charger.

The capacity of a power bank is measured in milliampere-hours (mAh), but this can be a little misleading because the amount of power you get out depends on the cable you use, the device you're charging, and the charging method (Qi wireless charging is less efficient). You will never get the maximum capacity from any power bank. You can generally expect to get between 60 and 80 percent after energy loss through heat and conversion. Some manufacturers list a “Rated Capacity” that's lower than the overall capacity to give you an indication of what to expect in real world use. We try to provide a minimum estimate of what you’ll get in terms of charges for devices.

The charging rate for devices like smartphones is measured in watts (W), but most power banks list the voltage (V) and the amperage (A). Thankfully, you can calculate the wattage yourself simply by multiplying the voltage and amperage. Unfortunately, getting that maximum rate also depends on your device, the standards it supports, and the charging cable you use. Many smartphones, including Apple’s iPhones, support the power delivery standard, meaning you can use higher-power power banks to recharge the device with no issues. A few phones, such as Samsung’s Galaxy S range, support a supplementary PD protocol called PPS (Programmable Power Supply) that goes up to 45 watts. Many phones also support Qualcomm’s proprietary Quick Charge (QC) standard. There are also other proprietary fast-charging standards, but you won’t generally find power banks that support them unless they come from the smartphone manufacturer.

Your device will need pass-through support if you want to charge your power bank and use it to charge another device simultaneously. The Nimble, GoalZero, Biolite, Mophie, Zendure, and Sharge portable chargers listed support pass-through charging. Anker discontinued support for pass-through in some of its products because it found that differences between the output of the wall charger and the input of the device being charged can cause the power bank to cycle on and off rapidly and shorten its life. Monoprice does not support pass-through charging either. We would advise caution when using pass-through, as it can also cause portable chargers to heat up.

Can I Take a Power Bank on a Plane?

AccordionItemContainerButtonLargeChevron

It’s safe to fly with a power bank, but there are two main restrictions to keep in mind when you board a flight: You must have the portable charger in your carry-on luggage (it cannot be checked), and it must not exceed 100 watt-hours (WH). If your power bank has a larger capacity than 27,000 mAh, you should check with the airline. Below that should not be a problem.

Some airlines introduced stricter rules in 2025, so always check with your chosen airline before you travel. For example, some airlines prefer you not to use or charge power banks during a flight, some require power banks to be in your hand luggage under the seat in front of you and not in the overheads, and some limit the number of power banks you can have onboard.

Why You Should Avoid Cheap Power Banks

AccordionItemContainerButtonLargeChevron

Many years ago, the Samsung Galaxy Note 7 gained notoriety when its batteries caught fire in a series of incidents. There's been a steady stream of similar, though isolated, incidents ever since. However, despite the high-profile coverage of batteries gone wrong, the vast majority of lithium-ion batteries are safe.

The chemical reaction that occurs inside a lithium-ion cell is complex, but as in any battery, there's a negative and a positive electrode. In lithium batteries, the negative is a lithium-carbon compound, and the positive is cobalt oxide (though many battery makers are moving away from cobalt). These two compounds cause a reaction that is safe when controlled and delivers energy to your devices. When the reaction gets out of control, though, you end up with earbuds melting in your ears. What changes a safe reaction to an uncontrolled reaction can be any number of things: excess heat, physical damage during use, physical damage during manufacture, or using the wrong charger.

The three basic rules that have kept me safe through testing dozens and dozens of batteries are these:

  1. Avoid cheap cords, chargers, and outlet adapters;
  2. Make sure batteries aren't exposed to excessive heat (above 110 degrees Fahrenheit);
  3. Regularly inspect batteries for signs of damage.

Avoiding cheap wall-outlet adapters, cords, and chargers is the most important. These are your most likely source of problems. Those chargers you see on Amazon for $20 cheaper than the competition? Not worth it. They probably got the price down by skimping on insulation, leaving out power-management tools, and ignoring the basics of electrical safety. Price alone is no guarantee of safety, either. Buy from reputable companies and brands.

Then there's heat. Too much of it can cause all manner of problems, both in terms of discharge and in terms of safety. Avoid heat, and pay attention to your batteries when they're charging. If your device gets overly hot when charging, this can be a sign of problems. Similarly, beware of any swollen, bulging, or otherwise misshapen batteries.

Why is My Power Bank Charging Slowly?

AccordionItemContainerButtonLargeChevron

I’ve explained charging rates and capacity above, but several factors can impact charging speed to be slower than expected. The rate is determined by the device being charged, so your phone will request a certain wattage, which changes depending on how full its battery is, on-device settings, and the battery temperature.

All devices charge more slowly when they are completely empty, when the battery approaches full, and when it overheats. The cable you use will also have a maximum charging rate, and so will different ports on the power bank. Wireless charging is more convenient, but also slower than wired charging.

How We Test Power Banks

AccordionItemContainerButtonLargeChevron

I've been testing power banks for close to two decades, and my home office has stacks of ’em at any given moment. I test every portable charger that comes in for at least two weeks. I always check how many times it can fully charge my test phone (currently an iPhone 16). I'll also try charging my Pixel 10 Pro XL and Samsung Galaxy S24+ to test charging speeds, and whatever else I have in. For larger-capacity power banks, I test-charge an iPad Mini and a MacBook Air. I test how long it takes to recharge each empty power bank.

Aside from these standard tests, I try to use the power banks in my everyday life, just to see how they feel, and my wife and kids often help out and share their opinions. For some of our top picks, I continue to test over months to get a sense of their reliability and durability, though it's not possible to do this for every device that lands on my desk. Beyond function, I take form and usability into account. I keep an eye on user reviews and consider the warranties and customer service of each manufacturer.

How Does WIRED Select Power Banks to be Reviewed?

AccordionItemContainerButtonLargeChevron

I often scan the latest releases to seek out worthy prospects, whether from an unknown new brand or an established favorite like Anker. I also get pitched many power banks every week. I sometimes reach out to these companies to ask for the product but never promise any kind of editorial coverage—that would be against WIRED's editorial policies. While WIRED usually earns affiliate revenue if you purchase a power bank using our link, this is not factored into the decision process when ranking.

There are too many power banks for me to test everything, so I tend to stick to reputable brands, but there's always room for something new if it has a compelling new feature or price, and I cover as many as I can. (Leave a comment or send me an email if you want me to test a power bank from a certain brand!) Once testing is complete, I typically donate power banks to a local charity. I try to hang on to some of our top picks for comparison purposes and to test their longevity.
