The ThinkPad X1 Carbon 2017 runs on USB Type C power, so your average charger won’t cut it — it needs PD support. Which also means that Type C port can take a power bank. Not a normal one, obviously. A special kind. High wattage, PD charging and output. So are there any cheap-but-decent chargers and power banks that fit? I refreshed Twitter and saw a post from Miboy Wu Lao’er, which reminded me of a brand: Xiaomi.
