The Ultratec Lithium 800 Lumen Lantern is a rechargeable camping and emergency lantern that gives up to 800 lumens from 24 warm-white LEDs. Warm white light is easier on the eyes than a cold blue-white, which makes it pleasant for lighting a lounge during load shedding or a campsite at night. It runs on a lithium battery of about 5Ah and doubles as a power bank, so you can keep your phone charged when the power is off. Retailer information for this lantern says it charges from a USB cable that is stored inside the unit and that it has an automatic switch-on function for when the mains power fails, so it can stand ready as emergency lighting at home.
