Summary
The Genmax GM15000ET is a 13,000-watt tri-fuel generator built for serious power demands. With 13,000 running watts and 15,000 starting watts, this unit can handle whole-house backup scenarios, including central air conditioning, refrigerators, well pumps, and multiple circuits running simultaneously. Because it runs on gasoline, propane, or natural gas, owners gain real flexibility during emergencies when one fuel source might be unavailable or during extended outages when tapping into a home natural gas line eliminates refueling trips entirely.
The WEN TF1300iX is a 10,500-watt tri-fuel inverter generator built around a 550 cc OHV 4-stroke engine. At this output level, it moves well beyond powering a few household circuits and enters whole-house backup and heavy job-site territory. It can comfortably run multiple high-demand appliances simultaneously, including central air conditioning units and full kitchen setups. The tri-fuel design adds genuine operational flexibility, letting owners switch between gasoline, propane, and natural gas depending on availability or cost during an outage.
