Charger with AC Mains Outlet offer price or trade

I'm selling a charger with an AC mains outlet. It comes with instructions on how to connect the input plug of the charger with the AC mains outlet. The indicator is on, then insert the output connector of the charger into the socket of the re-chargeable battery for charging. When charging is finished, the indicator turns into green. Stop charging by pulling the input plug of the charger out of the mains outlet first
