Another great solar lantern! The light is bright with a couple of settings for brightness or strobe. I find it is more effective when it is blown up but you can use it without blowing up the lantern. The charger is ok but I wouldn't rely on it as your only source of charging for your phone as it takes a long time to charge and you really need to be in direct sunlight the whole charging time. I think it's great as an emergency back up or if you are out long distance backpacking where there will be lots of sunlight and want to combine weights of a charger and lantern.
