Hi Jim Phocos has a 12v to 5v converter with USB output built into their Pico light. The battery in the light (4 x AA NiMH) can be charged off a 12 v PV or 12 v battery. They like to sell them with a small module and a few Pico lights. Maybe you can get just the converter from them?
I just got one of the Pico lights for around the house and it seems like a solid product so far (2 year warranty). LED with 3 light levels in multi use fixture that can hang from the ceiling, fit in your hand like a flashlight or be set down with several adjustable angles makes it versatile.
