Draper 650W Petrol Generator
Best OverallPros
- Very quiet operation for its class
- Lightweight and easy to carry
- Reliable 4-stroke engine starts easily
Cons
- Limited to low-power devices only
- Small fuel tank capacity
The Draper 650W is the quietest generator in this budget range, making it ideal for camping trips where noise restrictions apply. Owner reviews consistently praise its reliability and ease of use, with many reporting it starts on the first or second pull even after months of storage.
It is best suited for powering LED lights, a phone charger, a small TV, or a low-wattage fridge. It will not run a large power tool or a well pump, but for basic backup power and weekend trips, it is the most balanced option available under £200.
Sealey 850W Petrol Generator
Best Peak PowerPros
- Higher peak output for starting motors
- Sturdy frame with good build quality
- Low oil shutdown protection
Cons
- Heavier than competitors
- Louder than the Draper 650W
The Sealey 850W is built for those who need a bit more starting power. Its 850W peak output can handle the initial surge required by small fridge compressors or a 1/2-inch drill, making it more versatile than the standard 650W models.
Owner reviews note that it is a bit noisier than the Draper, but the extra power and low-oil shutoff feature provide peace of mind. It is a solid choice for emergency home backup where you need to keep a small freezer or a few lights running during a power cut.
Clarke 1000W Petrol Generator
Best ValuePros
- Highest peak output in this price range
- Good value for the power offered
- Includes a voltmeter for monitoring
Cons
- Heavier and louder than premium picks
- Build quality feels cheaper than Draper
The Clarke 1000W is the power king of the budget category. It offers a 1000W peak output, which is enough to start a small cement mixer or a 1.5hp water pump, making it a favourite among DIYers on a tight budget.
Owner reviews are mixed on noise levels, with some finding it acceptable and others noting it is quite loud. It is a no-frills machine that prioritises raw power over refinement. If you need the most watts for your money and can handle the extra noise, this is the best value pick.
Stanley 700W Petrol Generator
Best Build QualityPros
- Robust frame and solid construction
- Brand reliability from Stanley
- Good for light power tools
Cons
- Lower peak output than Sealey
- Not as quiet as the Draper
Stanley is a trusted name in tools, and their 700W generator reflects that with a sturdy metal frame and a well-built engine. It is designed to withstand the bumps of a job site or the back of a van better than some plastic-heavy competitors.
Owner reviews highlight its reliability and the peace of mind that comes with the Stanley brand. It is not the most powerful or the quietest, but it is a dependable workhorse for powering drills, saws, and lights on a small renovation project.
Draper 900W Inverter Generator
Best Inverter TechPros
- Clean power for sensitive electronics
- Eco-mode for fuel efficiency
- Quieter than standard generators
Cons
- More expensive, often over £200
- Less powerful than similarly priced units
The Draper 900W Inverter Generator is the only inverter model in this list. It produces clean, stable power that is safe for laptops, phones, and other sensitive electronics. Its eco-mode adjusts the engine speed to match the load, saving fuel and reducing noise.
Owner reviews praise its quiet operation and fuel efficiency, but note that it often sells for slightly over the £200 mark. If you can stretch your budget, this is the best choice for camping with electronics. If you are strictly under £200, availability may be a challenge.
What to check before buying a portable generator under £200
Before you buy, check the rated output (continuous power) versus the peak output (starting power). Most appliances need 2-3 times their running watts to start. A generator with a 650W rated output can only safely run a 500W load continuously.
Also check noise levels. Budget generators often run at 60-70 dB, which is loud for camping. Look for models like the Draper 650W that advertise lower dB ratings. Finally, check the fuel tank capacity and run time. Most budget generators run for 4-6 hours on a full tank at half load.
Mistakes to avoid
Overloading the generator is the most common mistake. Adding up the running watts of all devices you plan to plug in is essential. Never exceed the rated output for more than a few seconds.
Using extension cords that are too long is another issue. A long, thin extension cord causes voltage drop, which can damage your tools or the generator. Use a thick, short cord rated for the generator's output.
Forgetting to check oil levels before each use is a critical mistake. Many budget generators lack low-oil shutdown, so running them dry can destroy the engine. Always check the oil dipstick before starting.
FAQs
Can a portable generator under £200 power a fridge?
Yes, but only a small fridge. A typical fridge needs 600-800W to start and 200-400W to run. The Sealey 850W or Clarke 1000W are the best options for this.
Is it safe to run a generator in the rain?
No. Never run a generator in the rain or wet conditions. Always use a generator cover or operate it under a dry, well-ventilated canopy.
How often should I change the oil in a budget generator?
Change the oil after the first 5 hours of use, then every 25-50 hours of operation. Regular oil changes are essential for engine longevity.
Can I plug a generator directly into my house wiring?
No. This is called backfeeding and is extremely dangerous. You must use a transfer switch installed by a qualified electrician.
What is the difference between rated and peak output?
Rated output is the continuous power the generator can safely supply. Peak output is the short burst of power needed to start motors. You should not run devices at peak output for more than a few seconds.
Are inverter generators better than standard ones?
Yes, for sensitive electronics. Inverter generators produce cleaner power and are usually quieter and more fuel-efficient, but they cost more.
How long will a budget generator last?
With proper maintenance, a budget generator can last 500-1000 hours. Regular oil changes, clean fuel, and proper storage are key to longevity.
Can I use a generator for a welder?
No. A portable generator under £200 does not have enough power for even a small welder. You would need a generator with at least 5000W rated output.
What type of fuel should I use?
Use fresh, unleaded petrol with an octane rating of 87 or higher. Avoid using ethanol-blended fuel if possible, as it can damage the carburetor over time.
Do I need to run the generator at full throttle?
No. Most generators have an eco-mode or a throttle control. Running at full throttle when not needed wastes fuel and increases noise.
Our verdict
For most people, the Draper 650W is the best portable generator under £200 due to its quiet operation, light weight, and reliable performance. If you need more starting power for a fridge or pump, the Sealey 850W is the best alternative. For the best value in raw power, the Clarke 1000W is hard to beat, despite being louder and heavier.
