What is it? There aren’t many USB-C power banks out there for the new 12-inch MacBook, but this one from Maximas looks ace. It can charge two MacBooks simultaneously, or a MacBook and an iPad at the same time, giving you plenty of juice on the go. When’s it due? Grab one in February 2016. Why are we excited? It uses the same type of Panasonic battery cells that are used in Tesla’s electric cars, and with a capacity of 13,400mAh they should provide plenty of power to your MacBook. It all fits in the palm of your hand, too, so you can just pop it in your bag whenever you take your MacBook out and about.
