Urge 2000mAh Power Stick - 3pk

Waste of money. The red light does come on when it’s plugged in to charge, but the blue one doesn’t appear to exist. I have to assume that when the red light goes off, it’s charged.
I tried using it to charge one of my devices, and it started to charge, then rapidly began to drain the remaining charge from my device.
Pretty colour, though…
