The Mophie Powerstation Keychain gives you one more reason to make sure you’re always carrying your keys as you walk out the door. Roughly the size of a remote fob (the kind you find on car keys), the Mophie Powerstation Keychain is a small attachment for your keyring that gives you an instant 1200mAh of juice. The tiny powerbank sits along with your keys, and in dire situations, can top of your battery by as much as 50%, so you’re not struggling to book an Uber, or call your family at the end of the day on a dying battery. The Powerstation Keychain comes with its own integrated charging cable with a Type-C jack at the end, and even packs a carabiner clip, so you can hang it by your belt-loop, or on your backpack, using it to instantly charge your Android phone whenever you see the battery dropping into no man’s land.
