A keyring for charge, sync and more

WonderCube keyring

WonderCube is a 1-inch cube keyring that’s designed to function as numerous accessories for your iOS or Android smartphone. Unfolding it reveals its best-kept secrets. One side has a Lightning or microUSB connector while the other has standard USB allowing you to charge a smartphone or tablet when connected to a power adapter, or sync the device with a computer. And for those times when your smartphone is nearly dead and there’s no outlet or computer to be found, the top of the WonderCube opens to reveal an adapter letting you use a 9-volt battery to revive your device. It also provides users with extra storage via a microSD reader that supports cards up to 64 GB. The device also packs a flashlight (3 mm wide LED with a 3V button cell), and has a micro-suction cup plate on one side, meaning you can fix it to the back of a smartphone and use it as a stand.
