To the best of my knowledge, this is the only iPhone battery case other than Apple’s that recharges over a Lightning connector rather than microUSB. It’s also incredibly thin, and somehow doesn’t add a lip to the bottom of the phone. It seems too good to be true, but its 4-star review average proves otherwise.

This case typically sells for $50, but Amazon has it for just $33 today, an all-time low.
