I purchased this solar charger in spite of the previous review. I've used it to charge a Blackberry, IPOD, and Incredible phone. It comes with almost every phone adapter known to man, which plugs into either the 8.4 volt jack or the 5v USB jack. It has a LED that illuminates when the charger is exposed to sunlight. The internal battery can be charged with the included AC adapter which I haven't used yet. The battery has higher capacity than other devices that I looked at. The intended use of this device is to keep portable devices charged all summer while sailing where there is no power available at all.
The device is very high quality, using good quality solar cells and the feel of the device is very solid, it has a rubberized coating and solid feel to the hinge. Even the box it came in is really nice, which I'll keep as it has magnetic closures. Overall the product is well worth the price.
I only wish that the device was waterproof, so it can be left outside without worrying about it. It does fit very nicely inside a 1 quart zip-lock bag, which will probably reduce the solar efficiency by 10% or so, but that should be fine.
