Draper Petrol Inverter Generator, 700W

The Draper DGI800DI is the most compact, lightest petrol inverter generator in the entire Draper range. At just 10.2kg and measuring 425 × 230 × 380mm – roughly the size of a large toolbox – it redefines what portable power looks like. Pick it up with one hand, carry it on your shoulder, slide it under a market stall table, or tuck it into a motorhome locker that no other generator would fit. And yet, despite its extraordinary compactness, it delivers 700W of rated pure sine wave power (800W maximum) at a whisper-quiet 58dB(A) – safe and stable for laptops, cameras, battery chargers, LED lighting, CPAP machines, and a wide range of sensitive electronics.

Powered by a compact 40cc four-stroke petrol engine with easy pull recoil start, the DGI800DI runs for 4.1 hours at 100% load from its 2.1-litre tank, with a closed case design keeping noise levels impressively low throughout. A 230V socket handles mains-standard devices, while the 12V DC output and included charging lead take care of battery charging and 12V accessories. If the priority is getting clean, quiet power into the smallest possible package, the DGI800DI has no rival in the Draper lineup.

Key Features & Benefits

The Smallest and Lightest in the Draper Range – Just 10.2kg

At 10.2kg, the DGI800DI is the lightest petrol generator Draper makes – nearly 2kg lighter than the next model up (DGI1200DI at 12.1kg) and less than a third of the weight of the wheeled inverter models. Combined with dimensions of 425 × 230 × 380mm, it's genuinely hand-luggage portable: light enough to carry on your shoulder, small enough to fit where nothing else will. For anyone who has struggled with heavy, bulky generators or simply doesn't have the storage space for a larger unit, the DGI800DI opens up possibilities that weren't there before.

Closed Case Design for Maximum Noise Reduction

Unlike open frame generators, the DGI800DI features a fully enclosed case that contains engine noise and significantly reduces the sound reaching bystanders. At 58dB(A) measured at 7 metres – tied with the DGI1200DI as the quietest in the Draper range – it operates at the level of a quiet refrigerator or soft background conversation. Run it at a campsite, on a residential street, or at an outdoor event without drawing attention or complaints.

Pure Sine Wave Inverter Technology

The DGI800DI's inverter system produces a genuine pure sine wave output – clean, stable, and identical in quality to mains electricity. This makes it safe for sensitive electronics that would be damaged or disrupted by the rough waveform of a conventional generator. Laptops, camera chargers, tablets, smart devices, LED lighting, CPAP machines, and any appliance with a digital control board can all be plugged in with complete confidence.

700W Rated Output – Precision Power for Targeted Loads

700W is the perfect output for focussed, single-task power: charging a laptop and multiple USB devices simultaneously; powering LED site lighting; running a CPAP machine overnight; keeping a camera battery system charged on a remote shoot; or topping up a leisure battery via the 12V DC output while powering a phone charger from the 230V socket. It's not designed for high-draw cooking appliances – for those, step up to the DGI2600DI or DGI3500DI – but for its intended purpose it's precisely matched and impressively efficient.

4+ Hours Runtime from a 2.1-Litre Tank

The compact 2.1-litre fuel tank delivers 4.1 hours of continuous operation at 100% load. At the lighter loads that characterise most real-world use of a 700W generator – device charging, LED lighting, 12V battery maintenance – runtime extends comfortably beyond that. A single fill covers an evening, an overnight stay, or a full working session without the need to refuel.

Smallest Footprint in the Range

Measuring just 425 × 230 × 380mm, the DGI800DI fits in spaces that would defeat any other generator in the Draper lineup. Narrow motorhome lockers, under-bunk boat compartments, compact van shelves, market stall under-table space, garden shed corners – wherever space is the limiting factor, this generator fits.

230V Socket and 12V DC Output

A 230V socket covers standard mains devices, chargers, and low-draw appliances, while the 12V DC output with supplied charging lead handles vehicle battery maintenance, leisure battery charging, and 12V accessories. Two output types from the smallest possible unit.

40cc 4-Stroke Engine – Efficient and Reliable

A 40cc four-stroke petrol engine powers the DGI800DI. Despite its small displacement, four-stroke technology delivers clean, consistent combustion, good fuel economy for its size, and low long-term maintenance requirements – with no oil-and-fuel mixing needed.

Easy Pull Recoil Start

A smooth, reliable recoil pull start gets the engine running quickly and keeps weight and complexity to a minimum – entirely in keeping with the DGI800DI's lightweight, grab-and-go character.

E10 Fuel Compatible

Compatible with E10 unleaded petrol, available at virtually all UK forecourts. No specialist fuel, additives, or pre-treatment required.

Supplied with 12V Charging Lead and Toolkit

Ready to use from the box with a basic toolkit and 12V DC charging lead included.

Who Is the Draper DGI800DI For?

Backpackers & Minimalist Campers – The generator you genuinely take with you rather than leave at home because it's too heavy. At 10.2kg it fits in the boot alongside everything else, and at 58dB(A) it's welcome on virtually any campsite.

Photographers & Videographers – Power camera batteries, laptops, monitors, and audio recorders on remote shoots. Light enough to carry as part of a kit bag load, quiet enough not to appear on the audio track.

CPAP & Medical Device Users – A reliable, pure sine wave power source for CPAP and BiPAP machines when camping, travelling, or during power outages. Clean output protects sensitive medical electronics; light weight means it travels with you.

Narrowboat & Small Boat Owners – At 425 × 230 × 380mm and 10.2kg, this is the generator that actually fits in a narrowboat's gas locker or a small motorboat's storage bay. Provides 230V and 12V DC from a genuinely compact unit.

Market Traders & Artisan Sellers – Power a card terminal, LED display lighting, a laptop, or a small heated appliance from a unit that sits under the table and goes unnoticed by customers.

Festival & Event Crew – Silent, compact, and quick to reposition. Power comms equipment, charging stations, laptops, and lighting in locations where a larger generator would be impractical or prohibited.

Emergency Home Backup – Store it in a kitchen cupboard until needed. When the power goes out, it keeps routers, medical devices, phone chargers, and low-draw appliances running without taking over the room.

Frequently Asked Questions

How does the DGI800DI compare to the Draper DGI1200DI? Both share the same quiet 58dB(A) noise rating and pure sine wave output, but the DGI800DI is the more compact, lighter choice. At 10.2kg vs 12.1kg, and 425 × 230 × 380mm vs 555 × 315 × 490mm, the DGI800DI is measurably smaller and lighter – the better choice when portability is the absolute priority. The DGI1200DI offers more output (1,000W vs 700W), a larger tank (4.1L vs 2.1L), longer runtime (3.9 vs 4.1 hours at full load), and two 230V sockets vs one, making it the better choice when load headroom and runtime matter more than minimum size and weight.

What can I realistically power with 700W? 700W suits single-task or low combined loads very well. Practical examples include: a laptop (45–100W) plus phone and tablet charging; LED campsite or site lighting (20–80W); a CPAP or BiPAP machine (30–60W); a camera battery charging system; a cool bag or thermoelectric cool box (40–60W); or a small fan heater on a low setting (400–600W). It is not suited to kettles, microwaves, induction hobs, or other high-draw cooking appliances – for those, consider the DGI2600DI or DGI3500DI.

Is 700W enough for a CPAP machine? Yes. Most CPAP and BiPAP machines draw between 30W and 60W during operation – well within the DGI800DI's 700W capacity. The pure sine wave output is essential for CPAP machines, which contain sensitive electronics and in some cases humidifiers that are incompatible with modified sine wave power. The DGI800DI provides both the output and the power quality these devices require.

Why does it only have one 230V socket? At 700W rated output, a single 230V socket encourages correct use of the generator within its power limits. For applications requiring two simultaneous 230V loads, the DGI1200DI (1,000W, two sockets) or DGI2000 (1,700W, two sockets) are more appropriate choices.

How does the closed case design reduce noise? The enclosed housing contains and dampens engine and exhaust noise before it reaches the outside. Combined with the inverter's ability to run the engine at variable speed matched to the actual load – rather than a constant high speed – the result is significantly lower noise output than an open frame generator of similar power. At 58dB(A) at 7 metres, the DGI800DI is quieter than most household appliances at close range.

What fuel does it use? E10 unleaded petrol, the standard grade now dispensed at most UK forecourts.
