Written from the listing's specs, not from our own use · How we rate

On paper, the ERAYAK 4,500W Dual Fuel Inverter gets the important things right: 3,500 running and 4,500 peak watts, the choice of gasoline or propane and an inverter engine that idles down at light load. This ERAYAK inverter generator makes most sense for tailgates, RV trips and a short blackout; we rate it 7.2/10 from its listing.

3,500 running watts, 4,500 at start-up

That's the running figure the listing states, on gasoline. Room for the fridge, a few lamps, the router and the phones, as long as the coffee maker waits its turn. Central air and a 240 V well pump are out of its league.

What it has going for it

What changes at the campsite and in an outage

Gasoline or propane. Propane keeps for years in a sealed tank and won't gum up the carburetor between storms; gasoline gives you more watts. Propane is rated lower, so find that figure in the manual.

Inverter. The engine speeds up and slows down with the load, so it is quieter and thriftier at 3 a.m. when only the fridge and a lamp are on. The clean sine wave is kinder to laptops, TVs and the furnace control board.

Campsite or outage night?

At the campsite: it's an inverter, so the engine idles down at light loads, the listing states 58 dB, it has a TT-30R, the usual camper plug, two can be linked with a parallel kit and it weighs 54 lb, per the listing. Most campgrounds keep quiet hours, so ask before you pack it.

On outage night: 3,500 running watts keep the fridge cold and the lights and the Wi-Fi on, with the big draws taking turns. Central air and a 240 V well pump need more.

Great for you if…

You need the fridge, lights and phones, not the whole house
You'd rather store propane tanks than cans of gas
Laptops, TVs or a furnace board will be plugged in

Skip it if…

You never want to pull a cord: the listing names no electric start
You want central air or a 240 V well pump on it: 3,500 running watts won't do that
You'd rather wait for buyer reviews: none are captured for this listing yet

What ERAYAK promises

The seller states, word for word, in the ERAYAK 4,500W Dual Fuel Inverter listing:

This versatile generator supports gasoline (4500W peak, 3500W rated) and propane(4050W peak, 3150W rated).
Erayak's gas priority system auto-switches to gasoline when gas runs out, eliminating shutdowns for uninterrupted power.
The Erayak 4500PD inverter generator delivers 4,500W peak and 3,500W running power with pure sine wave technology (THD 0.2%~1.2%).
A full 2.25-gallon gas tank lasts up to 16 hours at 25% load, while connecting to a propane extends runtime beyond 20+ hours.
Built-in CO detection shuts down the generator when carbon monoxide levels are unsafe.

The seller's claims, quoted as written; we haven't measured any of it. The noise on your driveway and the surge of your well pump are things you only find out at home.

Price and cost per 1,000 running watts

$559 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $159.71 (price ÷ stated running watts, our arithmetic). That puts it in the cheaper third of the 33 generators up to 4,000 running watts we have a price and a stated running figure for.

The first fill of oil, a fuel can and a bottle of stabilizer are extra.

A better fit for your load list?

Rather not pull a cord on a January morning? The Westinghouse 5,000W Dual Fuel Inverter (9.2/10) has remote and electric start.

Planning an inlet box and a transfer switch? The A-iPower 5,000W Gas & Propane (7.3/10) has an L14-30R outlet.

Well pump or central air on the list? The Champion 8,500W Dual Fuel Inverter (7.8/10) is rated 7,000 running watts.

Our take

The verdict

What we'd buy the ERAYAK 4,500W Dual Fuel Inverter for is 3,500 running and 4,500 peak watts, with the choice of gasoline or propane as a bonus. No buyer reviews yet, so this ERAYAK inverter generator has to win you over on paper. The catch with the ERAYAK: no electric start in the listing, while most picks here have one. We'd pick it if you need the fridge, lights and phones, not the whole house; otherwise, put it next to the Champion 4,500W Dual Fuel Inverter first.

Living with it

Delivery day

At 54 lb (stated), have a second person or a dolly ready. Fill it with oil before the first start, then run it for a few minutes outside with a small load.

The first outage

Pull the cord, let it warm up, then add loads one at a time, the biggest motor first. Propane or gas: decide before the storm and have the hose and the tank ready. The 16 hours on the listing are at a light load; plan a refill at night.

Between storms

Run it every month or so for 20 minutes. On propane you avoid stale gas in the carburetor; on gas, add stabiliser or run it dry before storage. Our maintenance schedule has the full list.

Upkeep

First oil change after the break-in hours in the manual, then on schedule. Air filter and spark plug once a season, and a cover for the months it sits.

The one thing we'd check first

Before the ERAYAK 4,500W Dual Fuel Inverter ships, check your load list: 3,500 running watts (4,500 at start-up) have to cover everything you run at once, motor surges included.

Before you buy

Your load list

Read the label on each appliance (or the manual) for its running watts, and note which ones have a motor. Our running vs starting watts guide explains why the motor ones need the extra surge.

How it reaches the house

Plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes.

Where it will run

Outside only, about 20 ft from doors, windows and vents, exhaust pointing away (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details.

Fuel for three days

Gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.

Frequently asked questions

Is the ERAYAK 4,500W Dual Fuel Inverter any good?

We rate it 7.2/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the ERAYAK 4,500W Dual Fuel Inverter deliver?

The listing or manual states 3,500 W running and 4,500 W peak, usually for gasoline. Size your load list against the running watts and keep the peak for motor starts; propane and natural gas ratings are lower. These are the seller's figures, not our measurements (our sizing calculator turns your loads into a running and peak pair).

Which fuels does the ERAYAK 4,500W Dual Fuel Inverter run on?

The listing names gasoline and propane. Output differs by fuel, so check the per-fuel running watts in the manual and whether the hoses you need come in the box. Run it outdoors only, away from doors, windows and vents.

What do you get with the ERAYAK 4,500W Dual Fuel Inverter?

Its listing states 3,500 running watts (4,500 at start-up), the choice of gasoline or propane, clean inverter power, a CO sensor that shuts the engine off, up to 16 hours on a 2.25-gallon tank at 25 % load and a stated 58 dB. These are the seller's figures, not our measurements: how loud it is in your driveway and how it handles your well pump's surge can't be read from a listing.

What should I check before ordering the ERAYAK 4,500W Dual Fuel Inverter?

Your load list: read the label on each appliance (or the manual) for its running watts, and note which ones have a motor. Our running vs starting watts guide explains why the motor ones need the extra surge. How it reaches the house: plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes. Where it will run: outside only, about 20 ft from doors, windows and vents, exhaust pointing away (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details. Fuel for three days: gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.

Where can I buy the ERAYAK 4,500W Dual Fuel Inverter?
