Juice battery charger (West Croydon CR0)

Before everyone asks for this please read this listing carefully.

My neighbour an elderly lady threw this out in a bin, when I put a bag of rubbish in I saw this and being technically minded, I tested it myself as did not know why she threw it away.

Turns out it does charge up fine, and is on around 94% right now, however when you plug a cable in to charge say a phone etc it gives message on your device, saying not compatible. So she has bought another one now & so I might be close to recycling this mysrlf.

I've opened it up and battery's are fine, so suspect there's an issue with the circuit board recogning devices for charging.

So it's being given away as not working when it's actually charging just not external devices. Might be good for someone.
