Apple’s 12” MacBook is amazingly thin and portable, but for many users that comes at a cost of limited battery life. Fortunately, Kanex has your back with the GoPower USB-C Portable Battery ($100) — at 15,000 mAh portable USB-C battery pack with enough juice to deliver a full charge to your MacBook. In addition to the USB-C port, a standard USB-A port allows you to simultaneously charge an iPhone, iPad, or other mobile or tablet device, with 2.4A of power for high-speed charging.
