  • Bad design.
Color: 2S 2A
Yeah, junk, like others said. Not PD compliant, so you need the dumbest Type C supply, or type A supply with an A-C cable. It just need a 5.1K resistor to turn on; what a design oversight. Plugged it in, and it would not turn on, the rest I could not be bothered with. Also no BMS. For anything more than 1cell, it should state clearly there is no BMS. I should not have to guess. Open circuit board, maybe I'm building my own pack? ... show more

  • Only works with basic 5v usb ports
Color: 2S 2A
The charger works with basic 5v usb ports where there is always power. Basically it is expecting a direct DC input. It does not work with any smart chargers that do USB PD. Since this device cannot negotiate a USB PDO it won't turn on. Also worth noting that it gets quite hot while charging. Still works as advertised, just be aware of the limitation mentioned above. ... show more
