About $20, this little rascal folds flat for easy storage, charges easily while just sitting on the dashboard, and provides useful light for hours. It's easy to hang in a tent, or set on a table. Charge it via the supplied USB cable if desired.

Nice, I like that it's USB rechargeable. We have some of the little inflatable Luci lights. They work great, but, no sunshine, no worky later. This time of year the solar charging effectiveness really starts dropping off. I'll leave them on my dashboard all day and they still don't charge.
