海外TECH	Engadget	The best power banks for 2024	https://www.engadget.com/best-power-bank-143048526.html?src=rss	I considered buying an iPhone but realized I m perfectly happy with my iPhone Only thing is the battery doesn t last like it once did and often needs a top off before the day s done That became nerve wrackingly clear on work trip in which I found myself navigating a new city with three percent left on my phone Luckily I had a power bank These battery packs also come in handy when you re on your laptop at the coffee shop or when you head out on a long hike or bike ride Larger portable chargers let you set up a mobile command center out in the field charging a tablet refilling a camera even powering LED lights There s endless stream of portable batteries on the market with new models coming out often so we ve tested ーand continue to test ーmultiple options so you can find the best power bank for you 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 PortsWhile the tech world is thankfully moving towards USB C charging as the standard it s still a mixed bag in the power bank world All of our picks have at least one USB C port and a few also have a USB A port or two Newer Android smartphones charge via USB C iPhones still use the Lightning port but the latest tablets including current generation iPads and newer laptops are typically powered up via USB C 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 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 battery packs 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 largest banks take that a step further with an LED display indicating a percentage for the remaining battery which can be helpful if you re relying on a pack in a mobile office setting or something similar How we testedAmy 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 Magnetic Battery 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 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 Plus an iPhone a Samsung Galaxy S Ultra a th gen iPad Air and an M Pro inch MacBook Pro I charged one device 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 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 chargers Best MagSafe compatible power bank Spigen ArcHybrid MagI went into this category expecting Apple s own MagSafe battery pack to be a top pick And while it performed admirably charging a dead Plus to about percent in an hour and minutes Spigen s ArcHybrid delivered a percent charge in nearly the same amount of time The ArcHybrid firmly attaches to the MagSafe ring and it s flush enough that you can easily hold your phone and use it while charging up Unlike the Apple battery it includes four indicator lights to help you gauge how much juice the pack itself has left Considering Spigen s battery is cheaper than Apple s it s easy to recommend Alternatively Anker s Magnetic battery delivered a larger charge thanks to its mAh capacity boosting the iPhone to percent in three hours with enough left over for an additional percent top off And while the kickstand feature felt mildly useful the battery itself was bulky but that s understandable for a power bank that s twice as large as Spigen s Ultimately the ArcHybrid performed better as a quick and convenient way to give a partial charge to your iPhone on the go It s important to note that wireless charging is less efficient than wired Our tests showed wired battery banks deliver a device charge at around percent efficiency With the wireless chargers that rate dropped to an average of percent Something to keep in mind when weighing the costs both ecological and monetary of wasted energy Best power bank for a partial charge on an Android Anker Nano USB C Power BankThe Anker Nano power bank is impressive for how much charge it delivers in such a small package It s the exact size and shape of the lipstick case my grandma used to carry and has a built in USB C connector that folds down when you re not using it That means that in addition to being ultra portable you also don t need to remember to grab a charging cable when you toss it in your bag There s also a built in USB C port that can refill the battery or be used to fill up a different device with an adapter cable You also get four indicator lights that let you know how much charge remains in the battery In my testing the mAh battery provided enough charge to get a depleted Galaxy S Ultra back up to percent in about an hour That s relatively quick but the Nano is also small enough with an adequately sturdy connection that you can use your phone while it s charging without feeling too awkward For a little more juice and an equally clever design Anker s W Nano Power Bank is a good option It s bigger in size and capacity mAh and includes a display indicating the remaining charge percentage The attached USB C cable doubles as a carry handle which is a nice touch That cable is in out and there s another USB C in out port in addition to an out only USB A port Best low capacity power bank BioLite Charge PDBioLite is probably better known in the outdoor community than the tech world and it s fair to say that the Charge PD is geared more towards camping trips than urban commutes But this battery simply outperformed the others in its category The rugged yellow accented exterior is a refreshing change from the standard shiny black of many tech accessories It also has a rubberized finish and feels solid enough to handle the bumps and jolts of riding around in a purse or messenger bag all day It gave both the iPhone and the Galaxy one and a half charges which means it s plenty capable of reviving a dead phone a couple of times when you re out and about The Nimble Champ gets an honorary mention here because it ll also deliver a few reliable fill ups and comes in a rugged package It delivered a full charge to the iPhone in two hours plus percent more in minutes It gave the Galaxy a full charge in an hour and minutes then got the phone from dead to percent in minutes At the same price point as the BioLite Nimble gets extra points for being one of the few B Corp certified personal tech manufacturers out there meaning they ve committed themselves to higher environmental and social standards and took the time to prove it through B Lab s certification process Best medium capacity power bank Otterbox Fast ChargeAt the medium capacity level you can charge multiple devices at once or power up something larger than a phone The Otterbox Fast Charge power bank only lists mAh of capacity but it performed nearly as well as the mAh batteries while costing about less Over the month and a half I spent testing battery packs this was the unit I grabbed the most when my own devices dropped to empty It has a stylish exterior with a gray faux leather finish and copper detailing A little bigger than a deck of cards and weighing just over ounces it s a nice looking accessory that feels solid It filled up both smartphones twice then replenished each an additional third I introduced the iPad to the mix here and got a full charge plus an extra third The Otterbox also lost very little battery power while sitting dormant which means if you carry it around on the off chance that you ll need it it should have plenty of power when the time comes Best medium high capacity power bank Nimble champ PRONimble s new Champ Pro battery delivers a screaming fast charge and got a Galaxy S Ultra from five percent to full in under an hour That s faster than every other battery I tested except for Anker s our high capacity pick ーand that model costs more It lent nearly three full charges to both an iPhone and Galaxy device and has enough juice to refill an iPad more than once The battery pack itself also re ups from the wall noticeably faster than other models so it ll get you out the door quicker The company Nimble is a certified B Corp meaning they aim for higher environmental and social standards and verify their efforts through independent testing The Champ Pro uses percent post consumer plastic and comes in packaging made from paper scrap with a bag for shipping back your old battery or other tech for recycling The unit itself feels sturdy and has a compact shape that s a little narrower than a smartphone and about as long The attached adjustable lanyard is cute if a little superfluous and the marbled effect from the recycled plastics give it a nice aesthetic You can charge devices from both USB C ports simultaneously and both are input output plugs My only qualm was with the four indicator lights On a second testing round it dropped down to just one remaining pip yet went on to deliver a full fill up plus an additional top off after that That said I m glad the indicator lights under estimated the remaining charge rather than the other way around and the accuracy seemed to improve after subsequent depletions and refills Best high capacity power bank Anker PowerCore III Elite K Power BankIf you want something with a lot of charge that transfers quickly go for the Anker PowerCore III Elite K It was for the most part the fastest bank we tried capable of delivering the largest amount of charge in the shortest period of time for the iPad and Galaxy Anker s got the iPhone to percent an average of two minutes faster but didn t give as many charges The fully charged our S Ultra three times with enough power left over for another percent charge and those full charges completed in under an hour on average That s on par with wall charging The numbers for the iPhone were slightly less staggering but still impressive going from zero to full in about an hour and a half The iPad charged completely twice and did so in just over two hours which is also close to that device s wall connected charge speeds While it s great for multiple full charges on a given smartphone I should point out that the has three ports but only one of those provides USB C charging If you want to charge more than one device at a time you ll have to use the lower efficiency USB A ports for a couple of them That said this bank not only costs less than the other high capacity batteries we tried it also includes a W PowerPort fast charger which goes for on its own The design is nothing groundbreaking with a glossy black exterior and a metallic looking finish on one side It weighs a little over a pound and has the same general form as an old school TI graphing calculator Its single button has eight lighted pips to show you how much charge it has left Best mobile command center power bank Mophie Powerstation Pro ACThe TSA s watt hour battery limit translates to around mAh for lithium ion batteries Mophie s Powerstation Pro AC is so massive it necessitates a grab handle and get close to the edge of that max carry on size You probably won t find a larger acceptable portable power bank ーafter all an on the go charging brick is pointless if you can t travel with it I took this one through security at two airports and no one gave it a second glance To power your mobile work setup the Powerstation has four ports Three of them are the usual USBs but there s also a three prong AC outlet Most current devices charge via USB and doing so is more efficient than using a power adapter between the cable and power bank but older devices and certain mobile workstation accessories ーspeakers lights and printers come to mind ーmight only power up through a basic wall plug Just be sure to hold down the status button until the light turns red to turn on the AC port The AC plug powered most small appliances I plugged into it including a small speaker an HP printer and various LED lights The available watts isn t enough to continuously push a charge through the W power adapter that ships with the inch MacBook Pro but via the USB C port it was able to charge that laptop from percent to percent in under minutes The four lighted LED indicators will tell you when the battery is full Unfortunately it s not the best indicator of when the bank will run out of juice It charges for quite a while with four and three pips lit up but then quickly cycles through the last two dots before it dies So it might be better to just remember how much you ve used the brick rather than relying too heavily on its indicators Smaller devices like a smartphone will get numerous charges I got nearly five refills on an iPhone and two charges and some change on an iPad The Powerstation Pro AC was even a little faster at both tasks than our previous pick for a mobile command center That said this bank is overkill for a simple mobile device fill up At pounds it makes the most sense as a power source when you re working in the field with multiple components The Zendure Supertank Pro is also a great pick It s slightly smaller at mAh but has a lighted LED display that indicates exactly how much charge remains and how much you re using It has four variable wattage USB C ports a tough exterior and comes with a semi hard case nbsp Best premium power bank Anker Prime mAh nbsp nbsp Not only does Anker s new mAh Prime power bank look pretty slick it s also easier to recharge ーas long as you pony up for the companion base Magnets help align the pins so you can just plonk the battery down and move on with your life The set will run you which is pretty spendy for a battery bank but if you consider that the base offers extra ports one USB A and two USB C you can also use it as a power hub for other devices which takes some of the sting out of the price The battery itself has the same three ports as the base and a blocky upright design The case is a textured metallic plastic with a high polish built in screen and rounded corners It tells you how many watts are flowing out to each device and displays the overall remaining charge within the battery When you press the power button it takes a moment to wake But the extra processes that run the screen don t seem to slow the battery down or diminish the power it has to give Its charge times and capacity was on par with the other K batteries I ve tested I ve been pretty careful with my review unit but I d be worried that the sleek and shiny finish will get wrecked with regular use It does come with a faux suede pouch to carry it in but I doubt anyone will use that regularly ーafter all the whole appeal of the Prime s base and battery set is the low hassle efficiency Best power bank for outdoors Nestout Portable ChargerPlenty of battery packs are built to withstand drops and other abuse but very few are waterproof or even water resistance It makes sense water and electrical charges aren t good companions The Nestout Portable Charger battery has an IP rating which means it can handle being submerged in water for a number of minutes and Nestout claims a minute dunk in a meter of water shouldn t interfere with the battery s operation I couldn t think of a likely scenario where a power bank would spend a half hour in three feet of water but I could see a backpacker traversing a river and submerging their pack for a few minutes or a sudden downpour drenching all of their gear So I tested by dropping the battery in a five gallon bucket of water for five minutes After drying it off the unit performed as if it had never been wet The water resistance comes courtesy of screw on caps with silicone gaskets that physically keep the water out so you ll need to make sure you tighten but don t over tighten the caps whenever you think wetness is in your future The company also claims the battery lives up to a military standard shock drop specification which sounds impressive but it s hard to pin down what exactly that means I figured it should at minimum survive repeated drops from chest height onto a hard surface and it did As for charging speeds it wasn t quite as quick as our recommendation for a mid capacity bank The Otterbox charged an iPhone Plus to percent in about an hour and the Nestout got the smaller iPhone to percent in the same amount of time Another thing to note is that the supplied cable is short just seven inches total so you ll likely want to use your own cord Nestout also makes accessories for its batteries which I found delightful A dimmable LED worklight snaps on to the top of the battery while a small tripod holds them both up The portable solar panel reminded me of a baby version of Biolite s camping panels Nestout s version refilled the mAh bank to percent in under three hours which sounds slow but is actually fairly impressive considering the compact size of the panels This is also a blazingly hot summer so I d expect better performance in more reasonable weather This article
