The Brunton 26 Watt panel is pretty darn good but it does have a most annoying problem. Being folding up for storage you need a couple of rocks or some paracord (tensioned at each corner grommet) to hold it out flat in the direction of the sun.

For smaller devices such as GPSs and Cell phones, the Solar Gorilla used in conjunction with Mini Gorilla seem to fit the bill.

The Solar Gorilla gives around 10 watts output power and seems to work well in overcast conditions. The only downside of the Solar Gorilla is the weight which will be more than double that for the comparable 12 Watt folding Brunton and Sunlinq CIGS panels.

The Mini Gorilla looks to be an excellent bit of kit, it can deliver more than 25W power from a device weighing in @ 265 grams.

I've also recently become fond of the Tekkeon MP1800 portable power source. It has two 18650 lithium ion batteries


Are the 18650 cells replaceable in the MP1800?
