Is the ERAYAK 4500PD worth it?

At $447.61 at eBay as of November 3, 2026, it is cheap for a dual-fuel inverter with a 30A RV outlet and pure sine wave output. If you need electric start, the 4500PDE is the version to compare.

How much can it actually run?

Expect about 3,500W continuous on gasoline (3,150W on propane), enough for a 15,000 BTU RV air conditioner with soft start, a fridge, lights and electronics. Motor startup surges eat into the 4,500W peak, so add up surge loads before buying.

Gasoline or propane — which should I use?

Propane avoids stale fuel and carburetor problems and switches automatically, but it costs you about 10% of rated output. Gasoline gives full power and longer runtime from the 2.25-gallon tank.

Does it have electric start?

The 4500PDM is recoil start only. The 4500PDE adds electric start with recoil backup, so pick that model if pull-starting is a problem.

Can I connect it to my RV or a transfer switch?

Yes. The L5-30R outlet feeds a 30A RV cord with the included TT-30R adapter, and the parallel interface lets you pair a second unit for more power. Have a transfer switch installed for home backup rather than backfeeding a panel.

Generator prices tend to dip outside storm season and during fall sales events. The current $447.61 at eBay is already near the bottom of its recent range, so waiting is unlikely to save much.
