I've built a couple of these now and the kits are pretty good. Takes a few days of full sun to charge these up, you can't just leave it in the sun and have devices using it constantly because there's just not enough solar collection to power any devices.

It's much more for leaving in the sun to charge up and then using it. If you take it camping and empty in the evening it will be a long time before you can use it again which is why I have two. I use one while charging the other one.
