Clarke IG2200 Inverter Generator
Best for Portable PowerPros
- Very quiet at 58 dB
- Clean sine wave for electronics
- Lightweight and portable
Cons
- Fuel tank only 4 litres
- No remote start
The Clarke IG2200 is the most popular inverter generator in the range. It produces a true sine wave output that is safe for laptops, phone chargers, and sensitive medical equipment. Owner reviews consistently praise its low noise level, which makes it ideal for camping trips or use in residential areas where noise restrictions apply.
At 22.5 kg, it is manageable for one person to lift into a car boot. The 4-litre fuel tank provides around 6 hours of run time at 50% load. Some users note that the fuel gauge is not very accurate, but overall reliability is strong, with most owners reporting several years of trouble-free use with regular maintenance.
Clarke IG3300 Inverter Generator
Best for Heavy ToolsPros
- Enough power for a fridge and tools
- Parallel capable
- Fuel efficient
Cons
- Heavier than the IG2200
- No electric start
The IG3300 steps up the power to 3300W peak, making it suitable for running a fridge-freezer, power tools, or a small cement mixer. It retains the clean sine wave output of the smaller model, so it is still safe for electronics. The parallel capability allows you to connect two units for double the power if needed.
Owner feedback highlights the fuel efficiency, with the 5.5-litre tank offering up to 8 hours at half load. The main downside is the weight at 39 kg, which makes it a two-person lift. Some owners also wish for an electric start, as the recoil pull can be stiff when cold. Build quality is solid, with a robust frame that protects the unit during transport.
Clarke IG4000 Inverter Generator
Best for High DemandPros
- High peak power for large loads
- Clean power output
- Good run time
Cons
- Heavy and bulky
- More expensive
The IG4000 is the largest inverter generator in Clarke's lineup, offering 4000W peak power. This is enough to run a small welder, a large compressor, or multiple appliances simultaneously. It still produces a clean sine wave, so it remains safe for sensitive electronics, which is rare at this power level.
Owner reviews note that it is significantly heavier and larger than the smaller models, so it is best suited for site work or home backup where it stays in one place. The noise level at 65 dB is still quieter than a standard generator. Some users report that the fuel cap can be difficult to tighten properly, leading to minor leaks if not careful. Overall, it is a capable machine for those who need serious power in an inverter format.
Who is a Clarke inverter generator for?
Clarke inverter generators are ideal for users who need portable power that is quieter and cleaner than a standard generator. They suit campers, caravan owners, and DIY enthusiasts who want to run power tools or charge devices without disturbing neighbours. The clean sine wave output also makes them suitable for powering sensitive electronics like laptops, TVs, and medical equipment.
Performance and power output
Clarke uses Honda-clone GX series engines in their inverter generators. These are known for reliability and easy maintenance. The inverter technology adjusts the engine speed to match the load, which improves fuel efficiency and reduces noise. At 50% load, the IG2200 runs for about 6 hours on a full tank, while the IG3300 and IG4000 offer slightly longer run times due to larger tanks.
The clean sine wave output is a key advantage. Standard generators produce modified sine wave power that can damage sensitive electronics. Clarke inverters produce a smooth wave that is safe for all devices. Owner reviews confirm that the power output is stable and consistent, even under varying loads.
Build quality and warranty
Clarke generators are built with a robust steel frame and plastic panels. The build quality is generally good for the price point, though some owners note that the plastic panels can feel a bit thin. The engines are reliable if maintained properly, with regular oil changes and air filter cleaning. Clarke offers a 2-year warranty on most models, which is standard for the industry.
Alternatives to consider
If you are looking at other brands, the Honda EU22i is the benchmark for portable inverter generators. It is lighter and quieter than the Clarke IG2200, but it costs significantly more. The Hyundai HY2200Si is a direct competitor that offers similar specs at a similar price. For larger units, the Kipor IG3000 and the Pramac S2200 are worth comparing. Each has its own strengths in terms of weight, noise, and price.
What to check before buying an inverter generator
First, calculate the total wattage of the devices you plan to run simultaneously. Add a 20% safety margin to avoid overloading the generator. Second, consider the weight and portability. If you need to move the generator often, a lighter model like the IG2200 is better. Third, check the noise level. Inverter generators are quieter than standard ones, but some models are louder than others. Finally, look at the fuel tank size and run time. Larger tanks mean fewer refills but add weight.
Mistakes to avoid when buying a generator
Do not buy a generator that is too small for your needs. Underpowering can damage both the generator and your devices. Do not ignore the noise level if you plan to use it in a residential area or campsite. Do not assume all inverter generators are equally quiet. Do not forget to factor in the weight if you need to lift it into a vehicle. Finally, do not skip regular maintenance. Oil changes and air filter cleaning are essential for long life.
