The Arka from UCO is a unique hybrid tool that wields both power and light. Besides being a compact LED lantern/flashlight, the Arka features a rechargeable Lithium-Ion battery capable of serving as a portable charging station for any USB-compatible device such as phones, cameras, GPS, etc. Fully charged, the Arka"s super bright R4 XP-E CREE LED will burn on high (180 lumens) for 6-8 hours and on the lowest setting for up to 100 hours. The durable ABS/TPE housing expands to expose a frosted globe for diffused lantern mode and collapses for brilliant flashlight mode. The UCO Arka offers maximum flexibility in lighting: Press the variable power switch and the light will automatically start at maximum intensity. Continue holding the power switch and the light begins dimming. Release the button when the light level reaches the output you desire and the Arka maintains that brightness. In addition, red LEDs can be switched on and will cycle from tactical night vision to strobe to SOS emergency mode. Additional details include extendable feet at the bottom for enhanced stability, a split ring at the top for hanging and a glow-in-the-dark power button. An LED indicator light displays battery level and charging status. Charge up and toss the Arka in your backpack, luggage, briefcase or car for access to emergency power for your devices and light for your path. 100-240V wall charger and USB cable included.
