The main features are USB-C charging at around 2A, a decent 2.5A output capability and the ability to put out 5V while also being charged to allow UPS (uninterruptible power supply) style functionality. The circuit board has a standard power bank chip and also a combined control/MOSFET battery protection chip. At £5 it's worth buying the unit for the bare lithium cell, but note that it's a standard type and not the high current type suited to drones and other high current applications.
