Tronic power cube. Battery charger. (Fareham PO15)

This has a 12V battery inside it, and outputs for 3V, 4.5, 6, 9 and 12V. With lots of different connectors. Intended for charging up low voltage items like phones when you are off grid. It's been sitting on the shelf for a long time and I don't know if it still works, but it could be a bit of fun for someone who likes tinkering with electronics.
