Yamaha EF4500iSE Inverter Generator vs Pulsar PGD40iSCO Inverter Generator

These are different classes of generator. The Yamaha EF4500ISE is a heavy-duty 209 lb unit with 4000 running watts, electric start, a 4.5 gallon tank and a 3-year warranty; it suits job sites, home backup and long runs. The Pulsar PGD40iSCO is a 47 lb portable with 3200 running watts, recoil start, a 1 gallon tank and CO Sentry shutdown; it suits RV trips, tailgating and light backup. Owners of the Yamaha praise its quiet, stable power and durable engine; Pulsar buyers rate it well for portability and value but note the short runtime and pull start.

• Choose the Yamaha EF4500ISE if you need sustained 4000-watt output, electric starting, long runtime between fills and a long factory warranty for home backup or commercial use.
• Choose the Pulsar PGD40iSCO if you want a light, compact generator you can lift into an RV or truck, with CO shutdown safety and RV-ready outlets.
