Anker’s 25,000mAh power bank with two built-in, retractable USB-C cables might be as essential for you as it is for me. It offers fast charging speeds, serving up to 100W through either of its USB-C cables (one of which doubles as a handle when it’s not in use), or a combined 165W if you have them both charging gadgets simultaneously. I’ve tested this battery pack with phones, tablets, handheld game consoles, and various laptops, and they all charged quickly. In addition to its built-in USB-C cables, the power bank has one USB-C port and one USB-A port, so you can charge up to four devices at once (mind you, this drops the total combined charging speed to 130W). Its convenient LCD screen shows its current capacity along with how much power is being drawn by devices connected to it.
