I like having portable solar panels, for travel and for emergency use. In addition to charging the various household digital devices, this panel is great for my USB-powered battery chargers. What's nice about this one is it's a lot more powerful that the other panels I have. That comes at a cost, which I'll get into shortly.

The panel is advertised at 30W. I don't have the equipment to verify that, but I will say that it's a lot more powerful than my other panels that have lesser ratings. It made fast work of four rechargeable batteries. Construction appears to be sufficiently tough. The panels are thin and sealed. I wouldn't use this in the rain (probably wouldn't work to well anyway with no sunshine) but if it got wet briefly I wouldn't worry about it.

Due to its size and the way it's constructed, it's a little harder to open up and prop up. You can do it, but it takes some more effort. The charger has loops at each corner for hanging, and two clips are included for that purpose. Also, because it has a higher power rating it has to have more panels, and that means more weight. This isn't ultra-heavy, but it's probably not something I'd take backpacking. Car camping, sure.

There's only one USB port for charging, which is a bummer. My other panels have two ports.
