MacBook battery packs are a thing now. Since the adoption of USB-C, it has allowed third-party manufacturers to create portable batteries for MacBook and MacBook Pro. There are a few big players on the market, most recently Mophie. Aukey has also released an upgraded version of their massive 30,000mAh battery, so we went hands on to test it out.
USB-C has quite its list of advantages, but it was still a difficult design decision that still angers people to this day. Vinpok is looking to remedy that with their launch of the Bolt-S USB-C magnetic cable for MacBook and MacBook Pro.
