Draper Petrol Inverter Generator, 2800W

When power output and peace and quiet both matter, the Draper DGI3500DI stands apart. This compact, enclosed petrol inverter generator delivers a rated 2,800W (maximum 3,100W) of pure sine wave electricity at a remarkably low 62dB(A) measured at 7 metres – roughly the sound level of a normal conversation. That's significantly quieter than open frame generators, making it the right choice for campsites, outdoor events, residential use, and any setting where noise is a genuine concern.

Powered by a 149.5cc four-stroke petrol engine with easy pull recoil start, the DGI3500DI runs from a generous 7.5-litre fuel tank for 3.4 hours at 100% load. Its built-in carry handle and integrated wheel kit make it easy to move between locations without assistance, while pure sine wave inverter technology ensures the power it delivers is clean and stable enough for the most sensitive modern electronics – from laptops and flat-screen TVs to induction hobs and microwave ovens.

Key Features & Benefits

Remarkably Quiet – 62dB(A) at 7 Metres

At just 62dB(A) measured at 7 metres, the DGI3500DI is dramatically quieter than conventional open frame generators (which typically measure 95–96dB(A)). To put that in perspective, 62dB is comparable to background conversation in a restaurant. This makes it genuinely suitable for campsites with noise restrictions, residential neighbourhoods, wedding venues, film sets, and other noise-sensitive environments where a standard generator simply isn't an option.

Pure Sine Wave Inverter Technology

The DGI3500DI uses advanced inverter technology to produce a pure sine wave output – a smooth, stable waveform identical to mains electricity. This is essential for safely powering sensitive modern electronics including laptops, tablets, smart TVs, induction hobs, microwave ovens, CPAP machines, battery management systems, and any device with a digital control circuit. Unlike modified sine wave output from standard generators, pure sine wave eliminates the risk of overheating, interference, data corruption, or equipment damage.

Powerful 2,800W Rated Output

Despite its quiet, compact design, the DGI3500DI delivers a substantial 2,800W rated output (3,100W maximum) – enough to run multiple appliances simultaneously. Power a microwave, charge laptops, run an induction hob, and keep lighting going all at once, without compromising on cleanliness of supply.

Large 7.5-Litre Fuel Tank

The DGI3500DI's 7.5-litre tank is one of the largest in its class, providing 3.4 hours of runtime at 100% load. At more typical mixed loads, runtime extends considerably – comfortably covering evening and overnight use at a campsite or powering a full outdoor event without mid-session refuelling.

12V DC Output with Charging Lead

As well as two 230V sockets, the DGI3500DI includes a 12V DC output with a charging lead supplied in the box. Use it to charge or maintain vehicle batteries, power 12V accessories, or top up leisure batteries – making this generator a versatile companion for motorhomes, caravans, boat owners, and off-grid living.

Twin 230V Sockets

Two 230V sockets allow multiple appliances or devices to run simultaneously without extension blocks. Both deliver the same stable pure sine wave output, whatever you plug in.

Built-In Wheels and Handle for Easy Portability

At 33.5kg, the DGI3500DI is substantial – but the integrated wheel kit and built-in carry handle mean one person can move it easily across most surfaces. Roll it from the car to the pitch, between work areas, or around the garden without lifting the full weight.

E10 Fuel Compatible

Runs on standard E10 unleaded petrol, available at virtually every UK filling station. No specialist fuel, additives, or modifications required.

Supplied with Toolkit and 12V Charging Lead

Comes ready to use with a basic toolkit and 12V DC charging lead included in the box.

Who Is the Draper DGI3500DI For?

Camping & Motorhoming – Power an induction hob, microwave, TV, and charging points from one quiet unit that won't disturb neighbouring pitches or fall foul of campsite noise limits. The 12V DC output keeps leisure batteries topped up too.

Outdoor Events & Hospitality – Provide clean, quiet power for catering equipment, bar fridges, PA systems, and lighting at weddings, markets, festivals, and outdoor dining. Guests won't hear it running.

Home Emergency Backup – Keep essential appliances running during power cuts – fridge, freezer, TV, broadband router, medical devices – without the noise of a conventional generator disturbing the household or neighbours.

Content Creation & Film Production – A near-silent power source for cameras, monitors, lighting, and audio equipment on location where generator noise would ruin a take or require ADR.

Boat & Marine Use – Quiet, stable 230V power and 12V DC charging for aboard use, where noise and power quality are both critical and neighbours are close.

Garden & Outdoor Living – Power outdoor kitchens, garden lighting, tools, and entertainment systems without the intrusive drone of a standard open frame generator.

Frequently Asked Questions

How quiet is the Draper DGI3500DI? At 62dB(A) measured at 7 metres, it's among the quietest petrol generators available at this power level. For comparison, open frame generators of similar output typically measure 95–96dB(A). The difference is substantial – 62dB is closer to background conversation than industrial machinery.

What can I run on a 2800W inverter generator? At 2,800W rated output you can comfortably power a combination of appliances. Typical examples: a microwave (800–1200W) + induction hob (1000–1800W); or a TV + laptop + fridge + lighting; or a hair dryer + phone and device charging. Always check the combined wattage of your devices against the rated output.

Is pure sine wave output necessary for my devices? Most modern electronics – laptops, smartphones, flat-screen TVs, induction hobs, medical devices, variable speed tools, and audio equipment – perform best and are safest on pure sine wave power. Using a modified sine wave generator with these devices can cause overheating, erratic behaviour, reduced efficiency, or permanent damage. If you're in any doubt, the pure sine wave output of the DGI3500DI removes all risk.

How does this compare to the Draper PG3000DI open frame inverter generator? Both use pure sine wave inverter technology, but the DGI3500DI is dramatically quieter (62dB vs 96dB) thanks to its enclosed housing, making it suitable for noise-sensitive locations. The PG3000DI is an open frame design intended for commercial sites and hire use, while the DGI3500DI is the better choice for camping, events, and residential backup. The DGI3500DI also has a larger fuel tank (7.5L vs 5L) and includes a 12V DC output.

What fuel does the DGI3500DI take? Standard E10 unleaded petrol, available at most UK forecourts.

Is it easy to transport? Yes. The integrated wheel kit and built-in handle mean one person can manoeuvre the 33.5kg unit across most terrain without needing to lift it fully. Load it into a van or car boot with care and assistance.

Does it have overload or low oil protection? The inverter system provides inherent protection against overload conditions. As with all petrol generators, always check the oil level before starting and ensure loads don't exceed the rated output.
