There are so many things going right with the Orca Power Strap, but that is at the risk of you being the geekiest person your friends and family know. Small price to pay if you’re tired of all your gadgets running out of juice in the middle of the day, or even in the middle of the game. Give up your watch and wear a battery that’s able to charge your gadgets instead. This battery uses USB to charge itself. Once charged, you can use a USB cable to charge your devices. LEDs on the strap give you a visual as to how much power is left on your wrist before needing to be recharged.
