Waited till I used it to review & I just got back from camping with it! I was skeptical about the solar charging & lasting power but I used two lanterns at the mid setting all night & it lasted the entire time I needed it. I charged it during the day in direct sunlight & it actually charged enough to be able to use it again all night. It was a new moon during the trip so it was REALLY dark but these lanterns lit up our little common area so well. These lanterns works so well & are so efficient so I'm really glad to have bought some!
