Generac 19,300W Gas Review

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

The Generac 19,300W Gas ticks most of the boxes we care about: 19,300 peak watts, built-in CO sensing and electric start. With fuel injection (no carburetor to gum up) as well, it suits job sites and the odd outage at home.

19,300 peak watts

The listing states only the peak, the figure for the few seconds a motor starts. Ask for the running watts before you build your load list on it.

What it has going for it

What changes on the night the power goes out

CO sensor. A sensor that watches the carbon monoxide around the unit, per the listing. Treat it as a backup: the generator still belongs outside, about 20 ft from doors and windows.

Electric start. A button instead of a pull cord, which matters at 5 a.m. in sleet. Keep the battery topped up between storms (a trickle charger does it).

Great for you if…

  • Kids or pets in the house make CO safety a must
  • Pull cords are not your thing
  • It will sit for months between outages

Skip it if…

  • You plan to feed a 50 amp inlet box: the listing names no 50 amp outlet
  • You'd rather wait for buyer reviews: none are captured for this listing yet
  • You want quiet power at a campsite: it's an open frame, not an inverter

Outlets, fuel and what's in the box

What the Generac 19,300W Gas listing names:

  • 19,300 peak watts
  • Runs on gasoline
  • Electric start

Price and availability

See current price ↗

We have no recent price on file for this listing, so we don't print an old one.

Count the hookup in the budget too: a heavy cord, an inlet box and a transfer switch or interlock, wired by an electrician, are a separate bill.

The button opens the exact listing (ASIN B0BY9NGY8R), where today's price, stock and seller apply.

A better fit for your load list?

Want it quieter, or cleaner power for electronics? The GENMAX 17,000W Tri-Fuel Inverter (7.7/10) is an inverter, per its listing.

Want propane as a backup fuel? The Champion 16,875W Tri Fuel (7.8/10) runs on gasoline, propane and natural gas.

Planning an inlet box and a transfer switch? The Westinghouse 18,000W Dual Fuel (7.8/10) has a 50 amp outlet.

Our take

The verdict

Our favourite thing about the Generac 19,300W Gas is 19,300 peak watts, closely followed by built-in CO sensing. No buyer reviews yet, so the Generac 19,300W Gas has to win you over on paper. The catch with this Generac generator: no 50 amp outlet in the listing, while most picks here have one. We'd pick it if kids or pets in the house make CO safety a must; otherwise, put it next to the WEN DF1100X 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. Fit the wheel kit first; it is easier on the ground.

The first outage

Push the start button, let it warm up, then add loads one at a time, the biggest motor first. Keep stabilised cans ready, never refuel it hot.

Between storms

Run it every month or so for 20 minutes and keep the battery charged. With fuel injection there is no carburetor to gum up, but stale gas still hurts; add stabiliser. Our maintenance schedule has the full list.

Upkeep

First oil change after the break-in hours in the manual (the hour meter counts them), 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 you order the Generac 19,300W Gas, check the running watts: the listing gives only a 19,300 W peak figure, and the running figure is what decides what it can carry.

Before you buy

Your load list

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 (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 and storage

Gasoline goes stale in a few months: stabiliser, a dry place for the cans, and a run every month or so keep it ready. Our fuel storage guide and maintenance schedule cover both.

How it compares

How the Generac 19,300W Gas stacks up against the closest alternative, the WEN DF1100X.

Pick the WEN DF1100X if you want our higher-rated option (7.5/10), with more running watts (8,300 W) and propane as a second fuel; stay with the Generac 19,300W Gas for a higher peak (19,300 W).

Frequently asked questions

Is the Generac 19,300W Gas any good?

We rate it 6.8/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the Generac 19,300W Gas deliver?

The listing or manual states 19,300 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 Generac 19,300W Gas run on?

The listing names gasoline. Run it outdoors only, away from doors, windows and vents.

What do you get with the Generac 19,300W Gas?

Its listing states 19,300 peak watts, a built-in CO sensor, push-button electric start and fuel injection (no carburetor to gum up). 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 Generac 19,300W Gas?

Your load list: 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 (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 and storage: gasoline goes stale in a few months: stabiliser, a dry place for the cans, and a run every month or so keep it ready. Our fuel storage guide and maintenance schedule cover both.
