Portable 20w solar charger

Portable 20w solar charger: "I've been charging 18650 rechargeable batteries from a small 12v battery solar charger for a few months now. Not impressed with the charge rate, spending an entire sunny day only to maybe have a single 18650 battery charged. I decided to step it up a notch & bought a 20w 12v solar panel from an ebay auction. Now I had to decide either to mount the panel outside & run wires into the house or to make it portable. I decided on the latter, as 20w is a bit meager for a rooftop installation."
