Port flexibility is the big advantage here: you can charge up to three devices at the same time using one USB-A and two USB-C ports. Output varies depending on how many ports you use—up to 12W max from USB-A (single-port use) and up to 20W max from either USB-C port (single-port use). When charging multiple devices simultaneously, the max output is up to 15W (see the included max output details in the product listing).

For quick setup out of the box, Amazon Basics includes a 1-foot USB-C to USB-C charging-only cable. Built-in LED indicator lights make it easy to check remaining battery level at a glance. The compact shape (4.48 x 2.83 x 1.16 inches) and listed weight of 0.77 pounds make it a convenient option to toss in a bag for portable power.
