Champion 2200W Inverter review
Champion 92001i 2200W Petrol Inverter Generator
By Tom Calder
Champion's 2.2kW inverter generator: 1,900W running with true sine wave output, so it's safe for laptops, routers and TVs, plus two standard 13A sockets and an economy mode that throttles back at light loads. At 17.6kg it's easy to lift into a car boot. Like every petrol generator it must only run outdoors, well away from doors, windows and vents, and never in a garage, shed or porch, because of carbon monoxide.

What we like
- True sine wave output, safe for laptops, routers and TVs
- Two covered 13A sockets, an economy mode and low-oil shutdown
- 17.6kg: light enough for one person to carry
Worth knowing
- 1,900W running won't run a kettle, an electric heater or other high-draw appliances
- Petrol only: it needs fuel stored safely, and it can only ever run outdoors

Our review
Champion's 92001i is a compact 2.2 kW petrol inverter generator: 1,900 W running, clean enough output for electronics, two 13 A sockets and up to 10.5 hours from a 4-litre tank at light load. It weighs 17.6 kg, and like any petrol generator it belongs outside, well away from the house.
What it is
Champion UK lists the 92001i, nicknamed the Mighty Atom, at 2,500 W starting, 2,200 W maximum and 1,900 W rated power, from a 79 cc four-stroke engine with recoil start. It is an inverter, which Champion says gives under 3 per cent total harmonic distortion, so laptops, routers and televisions can run from it. There are two 240 V 13 A sockets and a 12 V DC outlet, and two units can be linked in parallel for more power.
Champion gives the weight as 17.6 kg dry and the size as 445 by 440 by 285 mm. Noise is 58 dB(A) at 7 m, and the manual adds 72 dB(A) at 4 m, so it is quiet across a garden but noticeable close up. The warranty is three years: one year parts and labour, then parts only, or 1,000 hours.
Running it
Champion quotes up to 10.5 hours at 25 per cent load from the 4-litre tank, with fuel use of 0.47 litres an hour at 25 per cent rising to 1.17 litres at full load. That makes a full tank last roughly three and a half hours flat out. It is E10 compatible, has an automatic low-oil shutdown, and takes 500 ml of oil, with 10W-30 recommended and a bottle in the box; the manual says to change it after the first five hours.
In a power cut, 1,900 W is usually enough for a fridge-freezer, lights, a router and phone chargers at once, but not an electric heater, kettle and oven together; add up the wattage labels before you plug in. Run appliances from heavy-duty extension leads plugged into the generator. Our guide to using a generator safely covers sizing and setup.
Carbon monoxide: outdoors only
Champion's manual is blunt: generator exhaust contains carbon monoxide, a colourless, odourless, poisonous gas, and using a generator indoors can kill you in minutes. It says never to use it inside a home or garage, even if doors and windows are open, and only outside, far away from windows, doors and vents, and it advises battery carbon monoxide alarms. Health and Safety Executive Northern Ireland says the same: do not use a generator indoors or in partially enclosed spaces, including homes and garages.
Never connect it to the house wiring by plugging it into a socket. HSENI warns that connecting a generator to your home could cause a surge in electricity that might result in injury or death. If you want it wired into the house, that is a job for a qualified electrician. The manual also says not to run it in wet weather.
How it compares
On our generator comparison, the Hyundai HY3250SEi gives 3,000 W running for bigger loads, with Hyundai quoting 5.5 hours at 50 per cent load, a different basis from Champion's 25 per cent figure. Hyundai's HY2350Si is the closest rival in size at 1,800 W running. If your needs are lights, a router and a fridge for a day or so, a battery power station is silent and fume-free; see our comparison of a power station and a generator.
Our verdict
A light, well-specified inverter generator with a long published runtime at light load, from a brand with a UK warranty. Buy it if you need hours of power through a long cut and have a safe outdoor spot to run it. Skip it if you have nowhere to run it well away from doors and windows.

Who shouldn't buy this
You only need to keep phones, lights and a router going through a short cut. A battery power station is silent, with no petrol to store, and gives off no fumes, so unlike a petrol generator it can be used indoors; follow its maker's charging and storage guidance. A petrol generator must run outdoors, well away from doors and windows, because of carbon monoxide.
