The Sigma 4000 is a portable inverter generator with 4000 peak watts and 3200 rated watts from a 149cc OHV four-stroke engine. It runs at a claimed 65 dB at 23 feet, which is quiet for its class, and its inverter output is clean enough for laptops, phones and TVs. It has two 120V 20A household outlets, one 30A RV outlet and parallel capability for pairing with a second unit. It suits campers, tailgaters and RV owners who want modest backup power without a loud open-frame generator, though its 1.06-gallon tank gives only about 6 hours at half load, so long outages mean refueling.
