Hi all,

I have several lights (8. 4v) and phones , headphones, USB rear lights, small lipo packs etc. They need usb or DC standard output at various voltages between 5 and 12v

Basically all sorts that need charging or power. I have now found and used a 18650 battery case that solves All these issues.

It's a fiver (link below )

It has 1a usb, 2.1a usb but, crucially , a DC standard output which is variable between 3,6, 9 and 12v (with various amperage to compensate)

It will run a 3 led solar storm
And a single led super bright Chinese light that I can't find a linknot

It will even run a Imax b6 lipo charger as long as the charge rate is low

And anything usb of course

Maybe just me but this has solved a lot issues for what I want/need so thought I'd share

I just loaded it with 6 x 2600mah Samsung cells from old ebike battery. Cells well used , not coping with ebike demands and about 80% capacity. In this they have a new a very useful life

Anyway I thought worth sharing
