Need portable power on the go? Vorson’s Bookmark packs a 2,500 mAh battery into a thin shockproof housing that’s just 4.7 mm thick.
On its bulging bottom you’ll find a standard-sized USB port, as well as touch-to-activate battery meter so you always know how much juice is left.
The battery works with any USB charging cable, including a micro USB cable.
Described by Vorson as the “world’s thinnest backup battery”, with the $60 Bookmark you won’t have to worry where your next charge will come from.
