[OxLUG] Mobile power from the sun

I'm off on my annual cycle/camping trip to rural central France soon and
basically will not have the possibility to charge anything while on the
road.

Does anyone have experience of these small foldout solar USB chargers, one I
think has 3 flower-like petals:

Or has better suggestions?


Best wishes Peter
