Ultra-Lightweight

Ultra-Portable lithium-ion generators starting at only 13 lbs! Now you can take power with you anywhere.

Power without a Sound

Noiseless lithium-ion technology means you can power every device and every electronic in complete silence.

No Fumes, No Fuss

Built eco-friendly, the Grengine lithium-ion generators power without the harmful fumes and bulky, messy canisters associated with gas generators.

Go Anywhere, Inside or Out

Because the Grengine is lightweight, silent, and fume-free, you can take it with you anywhere - inside or out.

Exchangeable Batteries

For added convenience, some models feature detachable batteries. This patented feature means you can keep a backup battery charged to extend run time. Additionally, when batteries reach end of life, you can simply recycle the battery, and keep the main unit.
