I have that same powerpack and keep it charged with a 30-watt solar cell set in a south-facing window. Free energy!!

Good choice. My ongoing experiments indicate that a 20 amp-hour batt is the minimum practical size.

I hope you guys using solar (PV) panels are watching the voltage closely or using a charge controller. It's quite possible to fry these batts with a 2A+ (30W) input -- don't ask me how I know, I don't wanna talk about my dumb-ass lapses.
