Our take on the Firman P03607 4550/3650 Watt Gas Recoil Start Generator

The Firman P03607 is a gas-powered portable generator with 4550 starting watts and 3650 running watts, enough to run a fridge, lights, and a few small appliances during an outage. Its 208cc engine and 5-gallon tank deliver up to 14 hours of run time at half load, and the Whisper Series muffler keeps noise around 68 dB. Reviewers like the simple recoil start, the roll-cage frame, and the included oil and tools. It is a solid choice for homeowners who want a basic, reliable backup power source without paying for electric start or inverter technology.
