海外TECH	Engadget	The best power banks for 2023	https://www.engadget.com/best-power-bank-143048526.html?src=rss	Whether you call them battery packs power banks or portable chargers these accessories do one thing well charge devices when you can t find an open outlet Small enough to fit in a day pack and sturdy enough to live at the bottom of your carry on battery packs can charge your smartphone tablet laptop or even all three at once depending on the size of the battery What size you ll need and any extra features you may find useful will largely depend on the devices you plan on charging up With so many options on the market right now we tested out a bunch of models to determine the best portable power banks you can get right now 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 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 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 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 delivered 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 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 In all we acquired battery packs ranging from small wireless banks to large multi device batteries Here s the full list 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 Mid capacity mAh Otterbox Fast Charge mAh Mophie Powerstation Pro mAh Anker PowerCore K mAh Nestout Portable Charger mAh High capacity mAh Mophie Powerstation Pro XL mAh Anker Power Bank mAh Zendure Supertank Pro mAh Mophie Powerstation Pro AC mAh We continually update this guide as companies release new products which means we have different devices on hand for testing For this guide we tested 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 or tablet from fully depleted to percent 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 Amy Skorheim EngadgetI used the 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 battery 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 charge 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 Specs mAh W max Ports One USB C in outCable USB C to USB CNumber of charges iPhone Charge time iPhone to in h mBest battery for a partial charge on an Android Anker Power BankUntil Android phones get something like MagSafe a wired connection makes the most sense for on the go charges The Anker Power Bank is a cleverly designed unit about the size and shape of a slim stick of butter The battery has enough capacity to charge a depleted Galaxy S Ultra to percent in a little over an hour so you ll be covered if you don t have long between flights to give your phone a bit more juice It also has a built in plug and allows for pass through charging which means it can act as a wall adapter if you re ever stuck with both a dead battery bank and phone but happen to be near an outlet It doesn t come with a cable though so you ll need to provide one that can go from the bank s single USB C port to your device Specs mAh W maxPorts One USB C and wall outlet prongsCable NoneNumber of charges Galaxy S Ultra Charge time Galaxy to in h mBest low capacity battery 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 a percent charge 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 Specs mAh W maxPorts One in out USB C two USB A out onlyCable USB C to USB ANumber of charges iPhone Plus Charge time iPhone to in h m to in mNumber of charges Galaxy S Ultra Charge time Galaxy to in h m to in mBest medium capacity battery 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 needed a charge 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 gave an additional third of a charge each 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 This category may have been the closest to call as Anker s Power Core performed slightly better than the Otterbox but Anker s price point is higher That said if you want a screaming quick charge for your Galaxy phone grab the It got the Galaxy up to percent three times taking about an hour each time It had enough left over for a small nine percent charge before it finally gave up While the battery did get pretty warm it never felt overly hot That one hour fill up is the fastest any power bank was able to deliver a charge to the Galaxy other than Anker s which shaved off a few minutes but costs more I also appreciated the s cool iridescent finish Update Anker s Power Core battery which we mentioned as an alternate medium capacity option has been recalled due to a potential fire hazard If you ve purchased the battery pack the Anker rep we spoke with recommended that you stop using the device and follow the guidelines from the EPA or local agencies to dispose of the battery Follow this link to learn how to initiate a refund nbsp Specs mAh W maxPorts One in out USB C one in out USB ACable USB C to USB ANumber of

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 is USB C 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 Specs mAh W max

Charge time Galaxy to in m average to in mNumber of charges iPad Air Charge time iPad to in h m average and to in mBest mobile command center battery 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

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 Specs mAh W maxPorts One USB C in out one USB C in one USB
