海外TECH	Engadget	The best power banks and portable chargers for 2024	https://www.engadget.com/best-power-bank-143048526.html?src=rss	The number of portable chargers on the market now is staggering but they are some of the most useful tech accessories you can get Small power banks with built in connectors are easy to toss in a bag so you always have a backup Bigger batteries with multiple ports and laptop level capacity can power a mobile workstation far from wall outlets And mid capacity models can give a quick charge to phones tablets ereaders ーeven game controllers so you can keep playing without sitting too close to a screen New battery packs come on the market all the time so we continually test the most notable models to help you decide which one will work best for your needs According to our tests these are the best power banks you can get right now nbsp nbsp nbsp What to look for in a portable battery packBattery typeNearly 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 battery life deteriorates due to partial charges One drawback you may have heard is the possibility of lithium ion batteries catching fire To limit the danger battery packs require internal mechanisms to limit things like voltage and pressure While you should still make sure a battery isn t exposed to unnecessary stress like excessive heat damage from drops or operating in freezing weather battery packs are considered safe enough to bring on an airplane According to the TSA external batteries rated at Wh or less which all of our recommendations are can fly with you just make sure you stash them in your carryon the next time you fly as they aren t allowed in checked baggage CapacityPower bank manufacturers almost always list a battery s capacity in milliamp hours or mAh Smaller batteries say those that can charge a smartphone to between and percent tend to have a mAh capacity Larger batteries that can recharge laptops and tablets or give phones multiple charges can exceed mAh Unsurprisingly the prices on most batteries goes up as 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 PortsSince Apple finally ditched the Lightning cable and adopted USB C we re getting closer to a standard for charging connections ーand all of our picks have at least one such port But plenty of other devices use older interfaces like USB A and microUSB ports plus Lightning for older iPhones You can find cables with just about any combination of those connections so when you re picking out a battery just check that one end of your preferred cord will fit When a battery pack has more than one charging port they usually serve different functions You ll typically see at least one port labeled in out which means you can use it to both charge the bank and charge your device While USB A output ports can power up smartphones and other small devices they can t charge larger devices Plus they aren t as fast as USB C ports overall That s something to keep in mind when you re deciding which ports and charging cables to use to connect your phone to the pack There s even more variation among USB C ports themselves with different ports on the same device supporting different power transfer rates What that means in practical terms is an iPhone will charge just fine plugged into a power bank s W port But to properly charge say a MacBook or similar laptop it ll need the extra juice supplied by a W port which larger power banks can offer Power banks with more than one port can also charge multiple devices at the same time but speeds and the overall charge delivered will be lower You ll also want to consider your charging cable For anything larger than a smartphone and to access fast charging capabilities you ll want to use USB C ports and cables But not all cables are created equal even when they have the same USB C plugs on the end If you want power delivery from a W USB C power bank port you ll need a W rated USB C cable Luckily power banks capable of delivering W tend to include a compatible cable For any devices that don t we ve tried and liked Anker s W USB C cable For smaller devices we used this W cable from Nimble and we don t recommend bothering with cables under W For around higher capacity charging cables will make sure you re not wasting time with connections that limit your potential power transfer DesignFor the most part these rechargeable batteries have a squared off brick like design though many nod towards aesthetics 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 stations 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 portable battery packsAmy Skorheim EngadgetBefore we even put our hands on a battery pack we did extensive research We considered brands Engadget reviewers and staff have tried over the years and we checked out customer ratings on retail sites like Amazon and Best Buy Here s the full list of power banks we ve tested which range from small wireless banks to large multi device batteries MagSafe compatibleApple MagSafe Battery Pack mAh Spigen ArcHybrid Mag mAh Anker Magnetic Battery mAh Anker MagGo Power Bank K mAh Anker Magnetic Battery mAh Anker MagGo Power Bank K mAh Low capacity mAh Anker Power Bank mAh Anker Power Bank mAh Nimble Champ mAh Biolite Charge PD mAh Anker Nano mAh Nimble Champ mAh Mid capacity mAh Baseus Blade mAh Otterbox Fast Charge mAh Mophie Powerstation Pro mAh Anker Prime mAh Nestout Portable Charger mAh Nimble Champ Pro mAh High capacity mAh Mophie Powerstation Pro XL mAh Anker Power Bank mAh Zendure Supertank Pro mAh Mophie Powerstation Pro AC mAh We re continuously updating this guide as companies release new products and we test them We remove some products as we find better top picks and we add updated specs and prices where necessary For testing we used each battery with some combination of an iPhone an iPhone Plus an iPhone a Samsung Galaxy S Ultra a th gen iPad Air and an M Pro inch MacBook Pro I charged one phone battery at a time even though some packs are capable of multiple device charging I charged the phones and tablets from between zero and five percent until they were percent full or until the power bank was dead and didn t use the device while they charged other than to power them on and enter the unlock code nbsp Amy Skorheim EngadgetI used the charging cable included with each power bank to charge the Galaxy S Ultra MacBook Pro and the iPad Air For the iPhones I used the USB C to Lighting cable that Apple provides In the case of the lower capacity power banks that didn t include a cord or included one with USB C to USB A connectors I used this W rated USB C to USB C cable For reference here are the battery capacities of each device we used for testing iPhone mAhiPhone Plus mAhiPhone mAhGalaxy S Ultra mAhiPad Air mAh inch M Pro MacBook Pro mAhI noted the times for each charge and the number of charges each bank provided I also paid attention to things like ease of use and overall design Here s what made the cut for best portable power bank nbsp nbsp nbsp Other power banks we testedBaseus Blade The Blade from Baseus has a unique flat shape that s just a little wider than an ereader ーwhich may make it easier to slip into a low profile laptop bag It charged a Samsung Galaxy S Ultra considerably faster than any other battery bank we tried getting it from four percent to full in just over an hour It then filled the phone back to percent from dead on a second charge in about a half an hour But is a lot for a standard power bank that holds fewer than two full charges But if you can find the Blade on sale snap it up Anker MagGo K Anker s k MagGo is pretty similar to our top pick for a MagSafe compatible battery pack It supports the Qi charging standard and props up your iPhone so you can use it or enable StandBy mode while powering up This one even lets you set the viewing angle from to degrees It was speedy in getting an iPhone up to percent in about minutes But for the added bulk it doesn t have as much capacity as the K MagGo holding just enough juice for a single full charge plus about percent But it is cheaper which may be key for some This
