海外TECH	Engadget	The best power banks and portable chargers for every device in 2026	https://www.engadget.com/computing/accessories/best-power-bank-143048526.html?src=rss	To find the best power bank out there I tested more than portable chargers and batteries from big brands like Anker Belkin UGreen and Mophie ーas well as from smaller players such as Biolite Nimble and Satechi I tested the batteries on a number of devices including iPhones Galaxy phones an iPad a MacBook and even my ereader and a PlayStation controller If you just want a brick that can charge anything go for Anker s kmAh Laptop Power bank It has two built in USB C cables a massive capacity and super fast charging speeds But if that s not quite what you re looking for you can check out our other picks for the best power banks below Best power banks for What to look for in a portable battery pack Battery type Nearly every rechargeable power bank you can buy and most portable devices contain a lithium ion battery These beat other current battery types in terms of size to charge capacity and have even increased in energy density by eight fold in the past years They also don t suffer from a memory effect where a battery s lifespan deteriorates due to partial charges Flying with portable batteries You may have heard about lithium ion batteries overheating and catching fire ーa recent Hong Kong flight was grounded after just such a thing happened in an overhead bin Current restrictions implemented by the TSA still allow external batteries rated at Wh or less which all of our recommendations are to fly with you but only in your carry on luggage ーthey can t be checked Recently Southwest Airlines was the first in the industry to take that rule one step further Now flyers on that airline must keep power banks in clear view when using them to recharge a device If the portable charger isn t actively in use however it can stay in your carry on bag in the overhead bin Capacity Power bank manufacturers almost always list a battery s capacity in milliamp hours or mAh Smaller batteries with a mAh capacity make good phone chargers and can fill a smartphone to between and percent Larger batteries that can recharge laptops and tablets or give phones multiple charges can exceed mAh and we have a separate guide that covers that entire category nbsp Unsurprisingly the prices on most batteries goes up as mAh capacity increases and since batteries are physical storage units size and weight go up with capacity as well If you want more power be prepared to spend more and carry around a heavier brick You might think that a mAh power bank could charge a mAh phone to percent twice but that s not the case In addition to simple energy loss through heat dissipation factors like voltage conversion also bring down the amount of juice that makes it into your phone Most manufacturers list how many charges a battery can give a certain smartphone In our tests mAh of battery pack capacity translated to roughly mAh of device charge mAh chargers delivered around mAh to a device and mAh banks translated to about mAh of charge That s an average efficiency rate of around percent Wireless Wireless charging whether through a bank or a plugged in charging pad is less efficient than wired connections But it is convenient ーand in most cases you can carry around and use your phone as it refills with a magnetically attached power bank Power banks with wireless charging are far better than they once were Just a couple years ago the ones I tested were too inefficient to recommend in this guide When batteries adhering to the Qi wireless charging standard started arriving in performance markedly improved To gain Qi certification a device has to support speeds of up to watts and include magnetic attachment points The MagSafe technology on iPhones were once the only handsets that were Qi compatible but now Google s Pixelsnap tech brings both the higher speed and magnetic grip to Pixel phones Samsung may follow up with its own version in future releases The latest wireless charging standard Q W is supported by the new iPhone phones as well as the Google Pixel Pro XL Battery packs that are Qi W enabled are starting to hit the market as well and the Ugreen MagFlow was the first on the scene Ports USB C ports can deliver faster charges than USB A ports and most of the portable chargers we recommend here have Type C connections But Type A jacks are still handy if you need to use a specialized cable for a certain device my camera s USB A to micro USB cable comes to mind There s also variation among USB C ports Larger banks with more than one port will sometimes list different wattages for each For example a bank with three ports may have two W ports and one W port There will also be at least one in out port on the bank which can be used to charge the battery itself or to deliver a charge to your device Wattages and in out labels are printed right next to the port ーand always in the tiniest font possible remember your phone is an excellent magnifying glass if you ever have trouble reading them As with standard wall chargers the port s wattage will determine what you can charge A phone will happily charge off a W connection but a W plug won t do much for your laptop And remember the cable has to match the maximum wattage A cable rated for W won t deliver W speeds Luckily some of the best power banks include a built in USB C cable That ll not only ensure you have the right cord it s one less thing you have to remember to bring along Design Once most rechargeable batteries were black with a squared off brick like design but now they come in different colors and shapes with attractive finishes and detailing While that doesn t affect how they perform it s a consideration for something you ll interact with regularly Some portable power banks include extra features like MagSafe compatibility a built in wall plug or even a kickstand Nearly all have some sort of indicator to let you know how much available charge your power bank has left usually expressed with lighted pips near the power button Some of the newer banks take that a step further with an LED display indicating remaining battery percentage How we test best power banks First I considered brands Engadget reviewers and staff have tried over the years and checked out customer ratings on retail sites like Amazon and Best Buy Then I acquired the most promising candidates and tested them in my home office Amy Skorheim for Engadget For testing I used each battery to charge both an iPhone and an Android phone as well as an iPad and a MacBook Pro for the larger portable chargers I let the devices get down to between zero and five percent and charged them until the devices were full or the power bank died nbsp For reference here are the battery capacities of the device I ve used for testing over the years iPhone mAh iPhone Plus mAh iPhone mAh nbsp iPhone Galaxy S Ultra mAh iPad Air mAh inch M Pro MacBook Pro mAh The iPhone has a slightly larger battery at mAh I continuously update this guide as companies release new products Other power banks we tested Here are a few picks that didn t quite make the cut but are worth mentioning nbsp Belkin Stage PowerGrip If you re into iPhonography this clever accessory could be worth a look Belkin s Stage PowerGrip is a mAh power bank that has both a wireless charging pad and built in cable But it s also a Bluetooth shutter with a quarter inch tripod thread The design resembles a standard digital camera and provides a sturdy grip once you magnetically attach your phone make sure you re either using a MagSafe case or no case to ensure a solid connection The shutter is conveniently placed and the remote speed was quick enough to capture the cute things my cat was doing The accessory can even act as a stand while it charges in either landscape or portrait orientation As a power bank it s slow taking about two hours to get my iPhone from three to percent but it has enough juice for a full refill plus a little more which could help if you re out taking pictures all day Anker MagGo for Apple Watch power bank The Anker MagGo for Apple Watch power bank combines a K battery with a built in USB C cable and a pop up Apple Watch charger I didn t formally test it as it s a little too niche but it deserves a mention for saving my keister on two occasions Driving to a hike my watch told me it was down to percent Thankfully I had this and could refill the watch before I got to the trailhead Later on an interstate trip I realized the travel charging station I d brought was a dud This kept my watch alive for the week I was away It does a good job simply charging a phone via the handy on board cable too But for those with an Apple Watch it s extra useful HyperJuice W Hyper s massive but sleek brick is one nice looking power bank The HyperJuice W packs a hefty mAh capacity enough to refill my tester phone about four times and get a MacBook Pro from near dead to percent It only has USB C ports but you at least get four of them USB C only is probably fine for most situations but a USB A port would be nice for charging the occasional older peripheral The wattage is pretty high for a power bank and it was indeed speedy It filled a Samsung Galaxy S Ultra in just over an hour But it s the same price and capacity as our Mophie Powerstation pick for laptop banks and that one has a better variety of ports Hyper s battery is also comparable to Anker s laptop battery which is cheaper has built in cables and has nearly the same capacity Plus that bank is just as swanky looking EcoFlow Rapid magnetic power bank I was curious to try out the first power bank from EcoFlow a company that primarily makes larger power stations and whole home backup batteries The first offering in the brand s Rapid series is a Qi enabled magnetic charger with a mAh capacity It looks quite nice with shiny silver accents and soft touch grey plastic on the MagSafe compatible front There s a little pull out leg that sturdily displays your phone as it charges and the attached USB C cable lets you refill devices directly then tucks out of the way when it s not in use But it didn t outperform our top pick in the MagSafe category in terms of both charging speeds and the amount of charge delivered Mophie Snap Powerstation Mini The Mophie snap Powerstation Mini is terribly well built It feels premium with a rubberized contact point for the MagSafe charging pad and a stand that runs the entire width of the bank itself making it extra sturdy It s compact too but only carries a mAh capacity which gets you a partial charge on most newer or larger phones Our current MagSafe iPhone pick has double the capacity a stand and a digital display ーfor just more than the Powerstation Mini Power bank FAQs What s the difference between a portable power bank and a portable charger A slew of terms are used to describe power banks including portable batteries portable chargers external battery packs and even somewhat confusingly USB chargers which is what wall chargers are often called They all mean the same thing a lithium ion battery that stores a charge so you can refill a smartphone tablet earbuds console controller ereader laptop or just about any other device with its own built in rechargeable battery nbsp There s little difference between the terms so the specs you ll want to pay attention to are capacity expressed in mAh size and weight so you can find the right balance between recharging what you need and portability Power stations on the other hand are distinct These are bigger units often around the size of a car battery that can be used to charge multiple devices multiple times but notably they can t be taken on airplanes Does fast charging actually ruin your battery Not exactly The real enemy of a battery s longevity is heat The faster you charge a battery the more heat is generated Modern phones have features that keep the battery cool while charging like physical heat shields and heat sinks as well as software features that slow down processes that generate too much heat Phone manufacturers are keen to promote a phone s fast charging abilities so they had to figure out ways to make faster charging work While there aren t long term studies on what fast charging does to a phone a study on EV batteries which use the same general concept of charged lithium ions flowing from one side of the battery to the other absorbing or releasing a usable charge showed a very slight decrease in capacity over time with only fast charging ーthough what actually made a larger difference was how hot the battery itself was due to ambient temperatures when it was charged In short fast charging could be slightly harder on your battery than normal charging But the safeguards most smartphones have make that difference fairly negligible To really ensure you re optimizing charging capabilities limit your phone s heat exposure overall Can you use a power bank for all your devices That depends on the size of the bank and the size of your device s battery A small mAh battery isn t strong enough to charge laptops but a portable charger with a mAh capacity will give your computer a partial refill You also have to consider port compatibility If your device has a USB port you ll be able to easily find a cable to connect it to a battery If your device has a more unique port such as a DC port you won t be able to use a battery Devices with an AC cable and plug can be charged and sometimes powered such as in the case of a printer or speaker by larger laptop batteries with AC ports This article originally appeared on Engadget at	2026-01-30 10:01:26
