The BioLite Alpenglow 500 Lantern is highly efficient and easy to use. Its ChromaReal Broad Spectrum LED accurately renders natural colors with a warm glow, but can also change colors! Shake it up and watch the pretty lights dance. The Alpenglow 500 is super bright, that's why it's powered by a healthy 6,400 mAh battery that even has a USB output so you can charge your essential electronics. An IPX4 waterproof rating means you don't need to worry if the weather gets a little less friendly at night.
