3,300 running watts, 3,800 at start-up

That's the running figure the listing states, on gasoline; on propane it drops to 3,100. 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.

Why it made our list

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. The listing puts propane at 3,100 running watts.

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 and the listing states 59 dB, per the listing. Campgrounds set generator hours; look them up before the trip.

On outage night: 3,300 running watts cover the fridge, the lights, the router and the phone chargers if you add them up first. Central air and a 240 V well pump are beyond it.

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: 3,300 running watts won't do that
You simply want our top pick: that's the Westinghouse 5,000W Dual Fuel Inverter (9.2/10)
You'd rather wait for buyer reviews: none are captured for this listing yet

What PowerSmart promises

The seller states, word for word, in the PowerSmart 3,800W Dual Fuel Inverter listing:

Delivers 3800 starting watts and 3300 running watts on gasoline, 3500 starting watts and 3100 running watts on propane.
Runs 8 hours at 25% load on its 1.3‐gallon gas tank, or up to 24 hours with a standard 20‐lb propane tank.
Features overload, short‐circuit and carbon‐monoxide sensor protection and low‐oil shutdown defends against potential hazards.

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

$499.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $151.51 (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.

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

Neighbours close by? The Westinghouse 4,000W Dual Fuel Inverter (7.4/10) states 52 dB.

Our take

The verdict

The PowerSmart 3,800W Dual Fuel Inverter earns its place with 3,300 running and 3,800 peak watts and the choice of gasoline or propane. No buyer reviews yet, so this PowerSmart inverter generator has to win you over on paper. The catch with the PowerSmart: 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 Westinghouse 5,000W Dual Fuel Inverter first.

Living with it

Delivery day

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 8 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 PowerSmart 3,800W Dual Fuel Inverter goes in your cart, check the propane rating: it is rated 3,100 running watts on propane against 3,300 on gas, so size your list for the fuel you will actually use.

Before you buy

Your load list

3,300 running watts and 3,800 at start-up, per the listing. Write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums.

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. Pick the spot now, before the storm. Our CO safety and placement guide has the details.

Fuel for three days

A 20 lb tank lasts far less than a day at half load on most big units; two or three full tanks make a realistic plan. Our fuel storage guide covers storing them safely.

Frequently asked questions

Is the PowerSmart 3,800W Dual Fuel Inverter any good?

We rate it 7.4/10 (good), #2 of 5 in our quiet generator ranking. The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the PowerSmart 3,800W Dual Fuel Inverter deliver?

The listing or manual states 3,300 W running and 3,800 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 PowerSmart 3,800W 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 PowerSmart 3,800W Dual Fuel Inverter?

Its listing states 3,300 running watts (3,800 at start-up), the choice of gasoline or propane, clean inverter power, up to 8 hours per tank at 25 % load and a stated 59 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 PowerSmart 3,800W Dual Fuel Inverter?

Your load list: 3,300 running watts and 3,800 at start-up, per the listing. Write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums. 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. Pick the spot now, before the storm. Our CO safety and placement guide has the details. Fuel for three days: a 20 lb tank lasts far less than a day at half load on most big units; two or three full tanks make a realistic plan.
