For a complete portable charging solution in one product, the Anker 733 2-in-1 65W GaN Wall Charger y 10,000 mAh Power Bank fits the bill by giving you an AC wall charger and power bank in one compact device. Taking advantage of Gallium Nitride (GaN) technology, Anker keeps the 733 compact without sacrificing power delivery. You get two USB-C and one USB-A port for charging up to three devices at the same time. Plug it into a wall for up to 65W of power, or take it with you to use as a 10,000 mAh power bank for up to 30W of on-the-go power. When the battery is running low, simply plug it in to have the Anker 733 recharge itself.
