Clarke vs Draper Portable Generator

Clarke vs Draper: Which Generator Brand is Better?

Both Clarke and Draper are well-established names in the UK tool market, but they approach portable generators from different angles. Clarke, under the Machine Mart umbrella, focuses on heavy-duty performance and longer runtimes. Their generators often feature larger engines and fuel tanks, making them suitable for demanding site work or powering multiple tools. Draper, on the other hand, offers more compact and lightweight models that are easier to transport and store, appealing to DIYers and occasional users. Owner reviews aggregated from retailers like Amazon and Machine Mart consistently praise Clarke for reliability and power, while Draper is noted for its value and portability.

Power Output and Performance

The Clarke IG3300 delivers a running output of 3.3kVA (3,000W) with a peak of 3.6kVA, powered by a 212cc OHV engine. This is enough to run a 2hp site saw, a 1,500W heater, and lighting simultaneously. The Draper 2.2kVA model provides 2.2kVA (2,000W) running with a 2.5kVA peak from its 139cc engine. This suits smaller tools like drills, grinders, and domestic appliances. For powering sensitive electronics like laptops or chargers, both models offer AVR (Automatic Voltage Regulation), but the Clarke's higher output provides more headroom. For site work where you need to run multiple heavy tools, the Clarke is the clear winner. For light DIY or camping, the Draper is sufficient.

Runtime and Fuel Efficiency

Runtime is a critical factor for portable generators, especially on site or during power cuts. The Clarke IG3300 features a 15-litre fuel tank that offers up to 12.5 hours of runtime at 50% load. This is a significant advantage for all-day use without refuelling. The Draper 2.2kVA has a 12-litre tank providing around 8 hours at 50% load. While 8 hours is still respectable for a day's work, the Clarke's longer runtime reduces downtime. Owner reports indicate that the Clarke's OHV engine is more fuel-efficient than the Draper's, giving better cost-per-hour over time. If you need to run a generator for extended periods, the Clarke is the better choice.

Noise Levels and Build Quality

Noise is a major consideration for residential use or noise-sensitive sites. The Clarke IG3300 operates at 68 dB(A), which is comparable to a domestic vacuum cleaner. The Draper 2.2kVA is louder at 72 dB(A), making it more noticeable. Both generators feature a tubular steel frame for protection, but the Clarke has a more robust build with a larger muffler and better vibration dampening. The Draper is lighter at 35 kg compared to the Clarke's 48 kg, making it easier to lift into a car boot. However, the Clarke's heavier build contributes to its lower noise and better stability. For quiet operation, the Clarke is superior.

What to Check Before Buying a Portable Generator

Before choosing between Clarke and Draper, check your power requirements. Add up the running watts of all tools or appliances you plan to run simultaneously. Ensure the generator's running output exceeds this total. Also, consider starting watts for motors (like pumps or saws), which can be 2-3 times higher. Check the socket types: both models offer 230V outlets, but the Clarke adds a 12V DC output for battery charging. Verify fuel type (both run on standard unleaded petrol) and storage space. Finally, consider noise restrictions if using in a residential area or campsite.

Mistakes to Avoid When Choosing a Generator

A common mistake is underestimating power requirements. Buyers often choose a generator based on peak output, not running output. Always use the running (continuous) wattage for calculations. Another mistake is ignoring fuel tank size. A small tank means frequent refuelling, which is inconvenient on site. Also, avoid buying a generator without AVR if you plan to power sensitive electronics like computers or TVs. Both Clarke and Draper models here include AVR, but cheaper alternatives may not. Finally, don't overlook weight and portability. The Clarke is heavy and requires a trolley or two people to move, while the Draper is more manageable alone.
