Has anyone out there had good luck with solar panels to recharge cell phones and digital cameras? I tried one without success. Good information is hard to get.

No, I had some bad luck with one.  Had a brunton solar panel (cheap-o one from REI) that failed to charge the MP3 batteries even with a whole July day of sunlight.  Better to just keep your chargers handy, and plug in at a restaurant, library, or laundromat.

Yeah, that has been my experience as well. I have two I-Sun daisy chained together and will not charge the battery pack or my cell phone. Money wasted in my opinion.

The trouble with solar charging is that our rechargeable batteries do not take well to trickle charging. They need the high pulsed current supplied by good chargers to get a full charge. is an excellent place to learn more than you ever wanted to know about all this, written by a man who makes his living charging and testing batteries.

I carry a small Maha charger and 6 AA cells, all weighing less than a solar charger, for my GPS. I need to find an outlet only every 4 or 5 days.

My son uses this cool looking tri-winged thing-a-mabob to charge his ipod, available from Apple. Also works on phones & other toys.

I highly recommend the Silva Solar II for 12v items like cell phones, gps and ipods and the Solar I for recharging AA batteries. Both are a little hard to find in the US but IMHO worth the internet searching. The 12v model is usualy priced around $90us and the AA model $50us.

I've used the AA version on long back packing and short cycling trips and love it. I have not used the 12v model but assume that it's just as effective. Jakub Postrzygacz used these on his Canning Stock Route trek.
