Whether Snachatting, catching Pokemon, emailing or actually calling people, a power bank for your smartphone is an essential. The new Dubleup designs do exactly what you think, but they are super-slim and lightweight—and they’re the size of a credit card. Complete with a built-in lightning cable, these gadgets are available for iPhone and Android and come in three colorways: gold, black or silver. Price is in Australian dollars.
