Good product, but you've got to know how to use it

This is a trickle-charge product. The nature of solar products is that the amperage of their charging fluctuates, which means that one should be careful when plugging in sensitive electronics. The best way to use this is to get an external battery pack and have the solar panel charge that. When the external battery is fully charged, you use that to charge your other electronics. The external batteries are light, small and pretty inexpensive (found on a variety of retailers). I do this when I go camping and leave the charger in the sun to charge my battery all day, which can then charge my GPS, phone, mp3 player, etc at night.
