Anker 521 Portable Power Station
Portable power in a compact package
The display can be turned off, and shows you current charge, power in and out, and time remaining.
The compact unit has multiple outputs for charging a wide range of devices.
Anker has used Lithium batteries in its 521 power station to create the most portable model in its series. At just under 10lb in weight, it nonetheless has a cell capacity of 256Wh and is convenient enough to take on a trip without it feeling like too much of a burden. Its body is plastic but sturdy, with grilles on either end. It charges from the mains via the bundled 65W power supply or through its USB–C port at 60W, and you can connect solar panels or a car battery for input to the rear socket by adding adapters.
