[RE-wrenches] reliable 12vdc to 5vdc converters for USB charging

[Steve McCarney]

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.
