These portable charging units may not be the ones you're looking for, but you'll never be on the dark side again with these MimoPowertube Star Wars themed Powerbanks. Priced at £16.99, you can save 10% by using the voucher code MIMO at the checkout. There are eight different designs on offer, such as a various lightsabers and characters from the franchise, such as Yoda, Boba Fett, and Darth Vader.
With a capacity of 2600mAh it should be able to provide most smartphones with a full charge, and it comes with its own set of adapters to fit most phones (although it can charge any fully operational device that uses a USB cable to recharge.) I would apologise for the punnage in this post, but you can now rest easy knowing that I won't force any more on you today.
