The rechargeable and collapsible Tetra LED Lantern + USB Charger + Flashlight from UCO, shifts easily between flashlight and lantern functions and features a USB-charger port perfect for charging a camera, mobile phone, or GPS. The Tetra has a durable, water-resistant housing that helps ensure illumination and a reliable source of power in foul weather. The Tetra offers a long-lasting battery life that will run for up to 120 hours on low, has adjustable brightness up to 170 lumens, and has 3 lighting modes that range from high to low to S.O.S. emergency strobe. Powered by a rechargeable 2.6AH Li-Ion battery, the frosted globe of the Tetra slides up for a diffused white light in lantern mode and collapses down for flashlight mode with a super bright R4 XP-G2 CREE LED beam projection of 10-140 meters.
