There are plenty of options to give your phone an extra jolt of juice while on the go, most notably battery cases. But battery cases are bulky, and if you prefer to retain the sleek silhouette of your mobile device, the $49 TravelCard Charger could be just the ticket. It's a credit card-shaped, wallet-sized portable battery for Lightning- or micro USB-equipped gadgets. It's a bit thick for most wallets, and it doesn't provide a ton of extra power, but it could definitely come in handy for an emergency power-up that doesn't take place at Starbucks.
If you want to keep your phone's frame sleek and battery-free, the TravelCard is a solid option. It won't necessarily fit in your wallet, but it's smaller and lighter than most backup batteries, making it easy to slip in your pocket. And it's much easier than carrying around a charging cable and wall adapter, hunting for power at the nearest cafe.
TravelCard is a backup battery that puts 1,500mAh of power in your wallet [Deal]
Why we love it: If you want a USB power bank that you can carry around in your wallet or bag for a backup boost of power, you should get the TravelCard Charger (for iPhones) or the TravelCard Charger (USB-C) for devices that charge via USB-C. Neither will fully charge most smartphones but they're good to have in a pinch. For reference, an iPhone XS requires around 2,700 mAh for a full charge, and these offer only about 1,500 mAh apiece.
The Jackery Bolt has a capacity rating of 6,000 mAh, which is enough to charge an iPhone X several times over. The Bolt is easy to use and has four pinpricks of blue light along the side that helpfully tell you how much power the bank has left. It also has a little built-in flashlight that doesn't take up any extra space and can come in handy if you're digging through your bag to find your keys. This feature, which none of our other picks have, also means that you don't have to use your phone as a flashlight and further wear down its battery.
Why we love it: The Anker PowerCore Fusion 5000 is the best power bank we've found that's also a good wall charger. Rather than having a wall charger that you leave at home and a separate power bank that you carry with you, this is a single gadget that does double duty. It's easy to use: Flip open the AC plug and stick it in a wall outlet to charge it, wait for the three little battery-status lights on the side to light up, then take it with you for hours of portable power. And you don't have to worry about your power bank dying while you're out and about, because you can charge it from any wall outlet.
Flaws but not dealbreakers: We would have liked to see a USB-C output port incorporated into this model, since USB-C is faster and increasingly common. We know the technology exists, because the Jackery 6700mAh Portable Charger with Dual USB Wall Charger we tested has this capability. Another big drawback with the Fusion is that it's less portable than something like the Jackery Bolt: It has a chunkier shape that's not as easy to slip into a pocket, and its lack of built-in cables requires you to pack an extra cable or two to charge your devices. As far as two-in-one power banks go, though, it's still fairly compact.
Seriously, this is the ultimate get-out-of-jail-free battery charger. Perfect for business travelers and digital nomads, you can toss this in your wallet or that little zipper of your day bag and forget about it until you need it. 2ff7e9595c
