GENMAX GM1200i Portable Inverter Generator – 1200W, Ultra-Quiet, EPA Compliant

Compact power for home backup and outdoor adventures

The GENMAX GM1200i packs reliable inverter power into a compact, travel-friendly design. Powered by a 57cc four-stroke OHV gas engine, it delivers 1200 starting watts and 1000 running watts with clean power (less than 3% THD). This makes it suitable for running sensitive electronics like TVs, laptops, lights, fans, and small tools while camping, tailgating, or during short-burst outages at home.

Designed with portability in mind, the GM1200i weighs just over 25 pounds and includes a sturdy carrying handle, so you can move it between a vehicle, campsite, or a storage spot with ease. The compact footprint fits neatly in a trunk or shed, helping you keep a dependable power source close at hand.

Smart, efficient operation

Quiet operation is a standout feature. At 23 feet with a 25% load, the generator operates at about 58 dBA, which is comparable to a calm conversation and minimizes noise disruption at campsites or around a home. With a 0.66 gallon fuel tank, it can run up to about 6.5 hours at 50% load, and Eco mode helps optimize fuel use for lighter loads, extending run time when you need it most.

Versatile power panel and safety features

The GM1200i offers practical outlets for everyday devices: 120V/20A outlets plus multiple USB ports (5V) for phones and small devices. It also includes a low oil alarm, overload alarm, and a CO detect shutdown sensor to help prevent unsafe operation. The unit is parallel-ready, enabling you to connect with compatible GENMAX units for extra capacity when needed.

Reliability and support you can rely on

EPA compliant, the GM1200i is designed to balance performance with emissions standards. GENMAX backs the generator with a 3-year warranty and free lifetime technical support from experts, so you have access to guidance if you need it while you set up and optimize your power solution.
