Our take on the Erayak 4500W Inverter Generator

The Erayak 4500W is a gasoline portable inverter generator with a 4.5 kW output and a 2.3-gallon tank. Inverter output makes it suitable for sensitive electronics like laptops, TVs and phones, not just power tools. The best new price is $499 at Erayak Power as of November 4, 2026, and only one store lists it new, so there is no competitive price to compare against.

Questions and answers

Is the Erayak 4500W worth it at $499?
At $499 it undercuts most 4500W inverter generators, which often run $700 and up. The catch is that only one store sells it new, so you have no price competition and limited buyer feedback to lean on.
What can a 4500W inverter generator run?
Expect a fridge, lights, a router, a TV and phone chargers at once, or a window AC or small welder on its own. Check the surge rating on motor-driven appliances, since startup draw is higher than running draw.
How long does the 2.3-gallon tank last?
Runtime depends on load; at half load a tank this size typically gives several hours, and less at full output. Erayak does not publish a runtime figure, so plan on refueling every few hours under heavy load.
Can I use it for camping or tailgating?
Yes, it is portable and the inverter output is safe for electronics. It runs on gasoline and must stay outdoors, away from tents and vehicle windows, because of exhaust fumes.
Does it come with a remote start or parallel kit?
The listing does not mention remote start or parallel capability, so assume a manual pull or key start and no paralleling out of the box. Confirm with the seller before buying if either matters to you.
When is the price lowest?
With one seller at $499 as of November 4, 2026, there is no discount history to time. Generator prices usually dip around spring storm-season sales and Black Friday, so watch then.
Where is the Erayak 4500W Inverter Generator cheapest?
At Erayak Power, for $499.00, as of our latest check.
