They of course come in a wide variety of characters in general, but the ones being unveiled at CE Week 2014 are Darth Vader and R2-D2. I'm sure they'd be a lovely addition to my Mimoco® Star Wars collection.
Each Star Wars x MimoPowerBot™ has a 5200mAh capacity lithium-ion battery with a 2.1A output, designed to charge not just smartphones, but also tablets or any other 5V USB-powered devices.
They're supposed to be able to charge a smartphone three times before needing to be recharged themselves, and they're just a neat thing to have in your bag. I can't imagine any self-respecting Star Wars fan wanting to be without one. And now you can pre-order yours for delivery by Christmas at a cost of just $59.99 US each. What are you waiting for?
