SPRING SALE! The GRENGINE™ UltraLite portable, rechargeable battery generator lives up to its name. Ultra-lightweight and ultra-powerful, the 480 Wh UltraLite is a multi-use, lithium-based, rechargeable electric generator capable of powering and charging electronics, providing backup power, and so much more. This is a great gift for outdoors lovers, remote workers, nature photographers, and anyone who just wants dependable, portable power at their fingertips.
No. It’s so much more! A 480-Watt hour, portable, silent, emission-free, lithium-ion, go-anywhere-do-anything electric generator. Despite being powerful, the UltraLite doesn’t use gas like conventional generators, so it’s good for you and good for the planet. And to make it even more eco-friendly, the UltraLite can be recharged completely off the grid using solar power—or even a stationary bike. Bet your gas generator can’t do that.
