Our review
Champion's 9375-watt dual fuel portable generator is a big, electric-start unit with a CO Shield shutoff and a 30-amp locking outlet meant for a transfer switch. This researched review follows Champion's owner's manual for the matching model 201277, plus CPSC, CDC and Ready.gov generator safety advice, and says where the listing leaves the exact model open.
What it is and who it suits
The listing we track does not name a Champion model number, so this review follows the manual for model 201277, a 7500W dual fuel electric start generator. Its ratings match the listing: 9375 starting and 7500 running watts on gasoline, and 8400 starting and 6750 running watts on propane. It also has CO Shield and a 30-amp L14-30R outlet, and Champion lists it at 205 pounds. If your box shows a different number, check that manual instead.
It suits a household that wants whole-house backup through a transfer switch, with the choice of gasoline or a propane cylinder. This review is researched, not tested. It relies on Champion's manual and on federal safety guidance.
Outlets and fuel
Champion's manual lists a 120/240V, 30A locking outlet (NEMA L14-30R), a 120V, 30A locking outlet (NEMA L5-30R), and four 120V, 20A GFCI outlets. The L14-30R is the one a transfer switch inlet cord plugs into. The gasoline tank holds 7.7 gallons.
CO Shield, and what it does not do
Champion says CO Shield technology monitors the accumulation of carbon monoxide, a poisonous gas produced by engine exhaust, and that if it detects unsafe elevated levels it automatically shuts off the engine. The same manual is blunt about the limit: CO Shield is not a substitute for an indoor carbon monoxide alarm or for indoor operation. It also warns that tampering with the system creates a hazardous condition and voids the warranty.
The manual's danger notice says that using a generator indoors can kill you in minutes, that the exhaust is a poison you cannot see or smell, and that you should never use it inside a home or garage even if doors and windows are open. It tells you to install battery-operated carbon monoxide alarms, or plug-in alarms with battery back-up. Our carbon monoxide alarm comparison lists options.
Where to run it
Ready.gov says generators and fuel should always be used outdoors and at least 20 feet away from windows, doors and attached garages. CDC gives the same distance for windows, doors and vents, and CPSC says at least 20 feet from the home. Champion's manual adds a minimum of 5 feet of clearance from combustible material and 3 feet of airflow clearance on all sides.
CPSC's safety alert says never to run a generator in homes, garages, crawlspaces or sheds, even with fans or open doors and windows. Our generator safety guide walks through placement, fuel storage and cords.
Powering the house
Champion says connecting to your home's electrical system requires a listed 30A transfer switch installed by a licensed electrician and approved by the local authority having jurisdiction. CPSC warns never to feed house wiring by plugging a generator into a wall outlet, a practice called backfeeding, because it endangers utility workers and neighbors. Our transfer switch comparison covers the switch side.
The manual also says never to use the generator to power life support devices. If someone in your home depends on powered medical equipment, tell your electricity provider and plan a separate backup.
How it compares with the other picks
Among the generators on our generator comparison, the Champion lists 7500 running watts. The DuroMax XP5500EH lists 4500 and weighs 124 pounds, while the Westinghouse 12500 dual fuel and the DuroMax XP12000EH each list 9500 running watts, at 212.1 and 224 pounds. The Honda EU2200i lists 1800 running watts at 47.4 pounds and is a different kind of machine.
Skip it if
Skip it if you live in a place with no safe outdoor spot, such as a unit with only a balcony, or if you only need to charge phones and run a few lights. A smaller inverter model or a battery station is easier to store. Also skip it if you do not want to arrange an electrician for the transfer switch. For the wider plan, see the power outage checklist.

Read the review →Questions
Does CO Shield make it safe to run in a garage?
No. Champion's manual says CO Shield is not a substitute for an indoor carbon monoxide alarm or for indoor operation. CDC says never to use a generator inside your home or garage, even if doors and windows are open.
How far from the house should the generator sit?
Ready.gov says at least 20 feet away from windows, doors and attached garages, and CDC says more than 20 feet from windows, doors and vents. Point the exhaust away from buildings and check your carbon monoxide alarms.
Can I plug it into a wall outlet to run the house?
No. CPSC warns that backfeeding through a wall outlet is extremely dangerous. Champion says a listed 30A transfer switch must be installed by a licensed electrician and approved by the local authority.
Which fuels does it use?
Gasoline or propane. Champion's manual lists 9375 starting and 7500 running watts on gasoline and 8400 starting and 6750 running watts on propane, so expect less output when you run a cylinder.
