Portable Battery Pack

I picked this up from an Australian seller on EBay. They no longer have stock; however there seems to be similar items available from overseas sellers.

Whilst it has an in built solar panel this is not an effective way to charge the battery.

This unit has switchable output voltages of, 4.5, 5.5 6.5 and 9V at 800mAh from a single LiPo cell.
I use the 9v output (which I measured to be around 8.6v) to run the CW rig.
