Best Generator Overall
The Honda EU22i is the benchmark for portable inverter generators. Its 2200W peak output handles a fridge, a few lights, and a phone charger simultaneously without voltage spikes, thanks to inverter technology. Owners consistently praise its whisper-quiet 47 dB operation at idle, making it suitable for campsites and residential areas. The parallel kit allows you to double output if needed. The main limitation is the price, as it sits at the premium end of the market. For a quiet, reliable power source that lasts for years, this is the one.

For home backup, the Honda EU22i again leads because it produces clean, stable power safe for sensitive electronics like boilers, routers, and TVs. Its 8.1-hour runtime at quarter load means you can run essential appliances through a typical UK power cut. The Eco-Throttle system adjusts engine speed to the load, saving fuel and reducing noise. The downside is that it won't power a whole house; you need to prioritise circuits. If you want to keep the lights on and the broadband running without waking the neighbours, this is your best bet.

The DeWalt DXGNI2200 is the easiest generator to get started with. It features a simple push-button electric start (no pulling cords) and a clear control panel with overload and low-oil shutdown indicators. The inverter output is safe for laptops and phones, and the 22.7 kg weight is manageable for one person to wheel around. Owner reviews highlight the clear manual and straightforward maintenance. The trade-off is a slightly higher price than some budget models, but the ease of use and DeWalt warranty make it ideal for first-time buyers.

The Ryobi RYi2300BTA offers exceptional value for money. It delivers 2300W peak power with a clean inverter output, and includes Bluetooth connectivity so you can monitor fuel level, runtime, and output from your phone. Owners report it runs a fridge, a TV, and a few lights easily. The main downside is its weight at 28.6 kg, which is heavier than the Honda. If you want modern features like remote monitoring and a lower price point, and you don't mind a bit of extra weight, this is the best budget generator.

For powering tools on site, the Einhell BT-PG 3000 is a robust choice. Its 3000W peak output can handle a large mitre saw, a compressor, or a pressure washer without tripping. The 42 kg weight means it is better suited for a van or garage than carrying by hand, but the large wheels and folding handle make it easy to move across a driveway. Owner feedback notes it is louder than an inverter model, but for raw power at a reasonable price, it is hard to beat. Ideal for serious DIYers or small trades.
Check price on Amazon →Best Lightweight / Compact Generator
The Bosch G2200 is the smallest and lightest in this list at 21.5 kg, making it perfect for camping, tailgating, or light home backup. It produces 2200W peak with inverter stability, and its compact shape fits in a car boot easily. Owners appreciate the low noise level and the parallel capability. The main limitation is the smaller fuel tank, giving around 6 hours at quarter load. If portability is your priority and you don't need all-night runtime, the Bosch G2200 is a top contender.

Power Output (Wattage)
You need to calculate running and peak watts. Running watts cover continuous load (lights, fridge), while peak watts handle startup surges (motors, compressors). A 2000-3000W inverter generator is usually enough for home essentials and DIY tools. Overestimating leads to a heavier, more expensive unit.
Inverter vs Conventional
Inverter generators produce cleaner, stable power safe for laptops, phones, and modern boiler electronics. They are quieter and more fuel-efficient. Conventional generators are cheaper and can deliver higher peak power but are louder and risk damaging sensitive devices. For home use, always choose an inverter.
Noise Level
Measured in dB at 7 metres. A quiet generator (around 50-55 dB) is essential for residential areas or campsites. Conventional models can exceed 70 dB, which is disturbing to neighbours. Check the spec sheet; the Honda EU22i is among the quietest at 47 dB.
Portability and Fuel Type
Weight and wheels matter if you move the generator. Petrol is the most common fuel in the UK, but dual-fuel models (petrol/LPG) offer longer runtime. Battery generators are emerging but still limited for high-power needs. Consider a wheel kit for heavier units over 25 kg.
Mistakes to Avoid
- Buying a generator with too little peak power for your tools or appliances.
- Ignoring noise ratings, leading to complaints from neighbours or campsite rules.
- Assuming all generators are safe for electronics without inverter technology.
- Forgetting to check fuel tank size and runtime for your intended use.
Generator FAQs
What size generator do I need for a house?
A 2000-3000W inverter generator will run a fridge, lights, a TV, and charge phones. For a whole house including a central heating pump, you may need 5000W or more.
Can I run a generator in the rain?
No, generators produce carbon monoxide and must be used outdoors in a dry, well-ventilated area. Never run one inside a garage or shed, even with the door open.
What is the difference between running watts and peak watts?
Running watts are the continuous power a generator can supply. Peak watts are the extra power needed for a few seconds when a motor starts. Always check both numbers.
Are inverter generators worth the extra money?
Yes, for home use. They produce clean power safe for electronics, are quieter, and use less fuel. The higher upfront cost is offset by better efficiency and longer appliance life.
How often should I change the oil in a generator?
After the first 20 hours, then every 50-100 hours of use. Check the manual for your specific model. Regular oil changes are essential for engine longevity.
Can I connect a generator to my house wiring?
Only with a properly installed transfer switch by a qualified electrician. Plugging a generator directly into a wall socket can backfeed the grid and kill a linesman.
What is the best fuel for a generator?
Petrol is most common and easy to store in small quantities. Dual-fuel models (petrol/LPG) offer longer shelf life for the fuel and cleaner combustion.
How long can a generator run continuously?
Most portable generators run 6-10 hours on a full tank at quarter load. Always let the engine cool and check oil levels before refuelling.
Is a generator safe for a fridge?
Yes, if the generator provides clean inverter power. A fridge needs about 600-800 running watts and up to 2000 peak watts on startup.
What is the quietest generator for camping?
The Honda EU22i is one of the quietest at 47 dB, similar to a normal conversation. It is ideal for campsites with noise restrictions.
Do I need to earth a generator?
Yes, always follow the manufacturer's earthing instructions to prevent electric shock. Many portable generators have a floating neutral, but earthing is still recommended.
Can I use a generator with a power washer?
Yes, but ensure the generator's peak wattage exceeds the power washer's starting surge. A 3000W generator can typically run a 2000W power washer.
Our verdict
For most UK homes, the Honda EU22i is the best overall generator, offering quiet, clean power for essentials and electronics. If you are on a budget, the Ryobi RYi2300BTA provides excellent features and value, though it is heavier. Both are reliable choices for home backup and DIY projects.
