1. About Champion Power Equipment

Champion Power Equipment is an American brand founded in 2003 that has grown into one of the most credible mid-market generator names in the UK and Europe. Where some brands at similar price points are built to a budget and little else, Champion has earned a reputation by doing something specific and doing it well: packing genuine engineering features - true sine wave inverter technology, patented dual-fuel systems, 15-second power delay protection, and proprietary Cold Start technology, into machines that undercut Honda and Yamaha by a meaningful margin.

In the UK, the primary retail partner for Champion is Machine Mart, where the range is stocked extensively across their 60+ stores and online. Machine Mart's position as the UK's largest specialist retailer of trade tools and machinery makes them the natural home for Champion, and their nationwide Click & Collect network is a practical advantage when buying a machine that weighs 40–90kg and needs a same-day collection option.

2. Inverter vs Conventional Generator - What to Buy

This is the single most important decision when buying a generator and the one most frequently misunderstood. The difference is not primarily about output wattage - it is about the quality of the electricity produced, and whether that quality matters for what you need to power.

Conventional (Frame) Generators

A conventional generator runs the engine at a fixed speed - typically 3,000 RPM for 50Hz AC power — regardless of how much load is being drawn. The electricity produced is adequate for motors, power tools, floodlights, and site equipment. It is not safe for sensitive electronics including laptops, phone chargers, TV sets, medical equipment, or anything with a modern switching power supply. The waveform produced is a rough approximation of a sine wave (sometimes called a "modified sine wave") that can damage or confuse the electronics inside sensitive devices. Conventional generators are typically louder, heavier, and less fuel-efficient than inverter machines of similar output, but they are cheaper per watt and significantly more capable at peak loads — important for starting motors and running multiple heavy tools simultaneously.

Inverter Generators

An inverter generator produces AC power, converts it to DC, then reinverts it to AC using an electronic inverter stage — creating a "true sine wave" that is mathematically identical to mains power. This makes inverter generators safe for all electronics, including laptops, CPAP machines, televisions, drone chargers, and professional audio equipment. The engine speed also varies with load (economy mode), making inverter machines significantly quieter and more fuel-efficient under partial load - which is most of the time in real use. The trade-offs are higher cost per watt, lower peak surge capacity, and more complexity to maintain.

The simple rule: if you need to power a laptop, phone, TV, CPAP machine, or any modern appliance, buy an inverter generator. If you need to run power tools, floodlights, or motors on a construction site and cost-per-watt matters, a conventional frame generator delivers more power for less money.

3. Dual Fuel and LPG - Why Champion's System Is Different

Several models in the Champion range carry a "Dual Fuel" designation, meaning the engine can run on either petrol or LPG (liquefied petroleum gas - propane). This is a meaningfully useful feature, but Champion's implementation has a specific advantage over most competitors that is worth understanding before purchase.

The majority of dual fuel generators on the market from other brands are retrofit conversions, a standard petrol engine with an aftermarket LPG kit fitted by the retailer or importer. These conversions typically void the manufacturer's warranty and can have reliability implications over time. Champion's dual fuel system is factory-fitted and patented, meaning the engine is designed from the outset to run on both fuels. The full 3-year warranty is maintained regardless of which fuel you use. This is the genuine differentiator - not the fact of dual fuel capability (which anyone can achieve with a retrofit), but the factory engineering behind it.

4. How Much Power Do You Actually Need?

Generator wattage is described in two figures you will see in every specification: starting (peak) watts and running (rated) watts. Starting watts is the maximum the generator can deliver for the two to three seconds needed to start a motor — washing machines, fridges, and power tools all need a surge of power on start-up that can be two to three times their running requirement. Running watts is the continuous figure the generator can sustain. Always size your generator on running watts required, but check that starting watts covers your highest-draw motor start.

5. Champion Mighty Atom 92001i — Best for Camping & Caravanning

The 92001i is Champion's headline product in the UK market and with good reason. At only 17.6kg it is the lightest 2,200W inverter generator available — lighter than the lightest 2,000W machine from Honda when the 92001i launched - and that weight difference is everything when you are carrying it across a campsite or lifting it into a motorhome locker.

The 79cc Euro V engine produces 2,200 max watts and 1,900 running watts with a true sine wave output that is safe for every piece of electronics you own. Run time is up to 10.5 hours at 25% load on the 4-litre tank - a full overnight session on low draw without refuelling. Noise level is 58 dB(A) at seven metres, which is comparable to a quiet conversation and well within the acceptable-at-a-campsite threshold. Champion's 15-second power delay protection means your laptop can remain plugged in when you start and stop the machine, a genuinely practical feature that competing machines at this price lack.

Who it's for: Campers, caravanners, canal boat owners, and festival traders who need a quiet, lightweight, safe power source for electronics. Also ideal as a home power cut emergency unit for charging phones and running essential appliances. Not suited to running power tools or heavy appliances - stay within the 1,900W running limit.

6. Champion Mighty Atom 93001i-DF — Best Dual Fuel Compact Generator

The 149cc engine produces 3,000 max watts on petrol or LPG, running at 58 dB(A) — still comfortably within acceptable campsite noise limits. For those increasingly affected by campsite and council restrictions on petrol generators, the LPG capability transforms the machine's usability. The 3-year warranty applies regardless of which fuel is in use.

Who it's for: Long-duration campers and caravanners, liveaboard narrowboat owners, market traders, and anyone whose site or location restricts petrol but permits LPG. The premium over the 92001i buys you dual-fuel flexibility and 3kW of output — meaningfully useful if you need a little more headroom than 1,900W allows.

7. Champion 500988-DF-UK 3.6kW Dual Fuel Inverter — The Mid-Range Workhorse

The 500988-DF-UK sits in the sweet spot of the Champion inverter range, more output than the suitcase-format Mighty Atom machines, dual fuel capability, and true sine wave inverter technology in a machine that remains genuinely portable with its built-in handle and wheel kit. The 212cc engine produces 3,600 max watts with a quiet 61 dB(A) operating level, and runs for up to 14 hours on petrol or up to 21 hours with a 9kg propane cylinder.

A key specification advantage over cheaper machines is the 15-second power delay on start and shutdown,  electronics remain plugged in throughout. The optional parallel kit allows two 500988 units to be linked for up to 7.2kW of combined output, a genuinely useful feature for event use or running a whole-home backup circuit. At £999 it sits at the higher end of the inverter range, but the dual fuel capability, inverter quality, and output level justify the position.

Who it's for: Motorhome owners who need to run air conditioning or a heat pump; home backup buyers who want inverter-quality power for their electronics alongside the ability to run a fridge and heating circuit; event traders who need extended LPG runtime and can't use petrol. The parallel kit option makes it attractive for those who want scalable output.

8. Champion 73120i 3.1kW 110V Inverter - Best for Construction & Trade

The 73120i is Champion's answer to the construction site, a 3,100W inverter generator with a 110V output configuration specifically suited to site tools and compliance with UK site safety requirements (which typically mandate 110V power tools via a centre-tapped earth transformer for shock protection). The 171cc engine runs at 57 dB(A) and delivers true sine wave power for 8 hours at 25% load from a 6-litre tank, with electric and recoil start options and a never-flat wheel kit for site manoeuvring.

The Intelliguage display, showing voltage, frequency, and load is a genuinely useful site-use feature: you can monitor in real time whether the generator is approaching its load limit before a sensitive piece of equipment experiences a power event. Parallel connectivity means two 73120i units can be linked for doubled output on demanding sites.

Who it's for: Electricians, builders, groundworkers, and contractors who need 110V site power with inverter-quality output. Also useful for agricultural applications where sensitive electronics are present alongside power tool demand. Not suitable as a domestic camping or home backup unit - the 110V output requires the right plugs and equipment.

9. Champion CPG7500E2-DF 7kW Dual Fuel — Heavy Duty Home & Site

The CPG7500E2-DF is where Champion steps up from portable inverter machines to serious frame-mounted power. A 439cc OHV engine produces 6,000 running watts on petrol (5,000 on LPG) with a 7,000W petrol starting peak — enough to run a whole-home backup circuit including boiler, fridge, chest freezer, lighting, and several appliances simultaneously. The 23-litre petrol tank runs for 8 hours at 50% load, or up to 19 hours from a 19kg propane bottle on LPG.

This is a conventional (non-inverter) generator: the power quality is adequate for motors, appliances, and heating controls, but is not the clean sine wave output required for sensitive electronics without additional filtering. For most home backup scenarios this is not a problem — fridges, freezers, boilers, and lighting all run reliably from conventional generator power. If you need to power a high-end TV or sensitive computer equipment directly, consider adding a UPS (uninterruptible power supply) between the generator and those devices.

Who it's for: Homeowners in rural areas or areas prone to extended power cuts who need to run essential circuits during an outage. Agricultural users who need site power for multiple tools simultaneously. Light commercial applications including market stalls, events, and catering where petrol is permitted.

10. Champion CPG9000E2 8kW — Home Backup & Commercial Site Power

The CPG9000E2 is the largest petrol-only generator in the Champion UK range - a 459cc, 15hp Euro 5 OHV engine producing 7,500 running watts and 9,375 starting watts from a 25-litre tank that will run for 10 hours at 50% load. At this output level the machine covers a whole-home backup scenario comfortably - boiler, kitchen appliances, lighting, electric heating circuits, and sockets throughout the property, and has the headroom to cope with the starting surge of motor-driven equipment.

The CPG9000E2 is a conventional generator (not an inverter unit) and is loud at approximately 74–76 dB(A), appropriate for outdoor use well away from neighbours, not for a campsite. It is built for work: durable tubular steel frame, integrated U-handle, wheel kit, and electric push-button start with recoil backup. At this price point it competes directly with Clarke and Hyundai open-frame petrol generators, where Champion's engine reliability and 3-year warranty terms distinguish it.

Who it's for: Rural homeowners who need genuine whole-home backup power during extended outages. Agricultural and equestrian businesses needing site power for multiple circuits. Light industrial and construction site use where significant power demand is expected across a full working day.

13. Champion Features Explained 

Champion's product descriptions can feel heavy on branded terminology. Here is what each key feature actually means in practice:

True Sine Wave Inverter Technology

The electricity produced by the generator is mathematically identical to mains power — the waveform is a smooth, clean sine wave rather than the approximation produced by conventional generators. This is what makes inverter generators safe for laptops, phones, televisions, CPAP machines, and any device with a modern switching power supply. If a device has a multi-voltage power adapter or a lithium battery charger, it needs true sine wave power. All Champion inverter models produce true sine wave output.

15-Second Power Delay

When you start or stop a Champion inverter generator, there is a 15-second delay before power either comes on or cuts off. This prevents the power surge that occurs at start-up from flowing into connected electronics, and allows connected devices to safely power down at shutdown rather than experiencing an abrupt cut. In practical terms: plug your laptop in, start the generator, wait 15 seconds, and the power comes on cleanly. No spike, no damage.

Economy Mode

Champion inverter generators include an economy mode that reduces engine speed when load is low. This reduces noise, reduces fuel consumption, and reduces engine wear during periods of partial loading. On a full overnight camping run where you are only charging a phone, economy mode can extend runtime by 30–40% over a fixed-speed machine.

Parallel Capability

Several Champion inverter models can be connected in parallel using an optional parallel kit, linking two identical machines to effectively double the available output. Two 92001i units in parallel produce 3,800W-  matching the output of a single 500988 at a lower cost per machine if you are already using one for other purposes. The parallel connection also provides redundancy: if one machine fails the other continues.

Volt Guard / Cold Start Technology

Volt Guard is Champion's proprietary surge protection system that protects connected appliances from voltage spikes caused by load changes. Cold Start technology uses enhanced choke control and a richer starting mixture to ensure reliable engine start in cold UK morning conditions, particularly relevant for winter caravan use or agricultural applications where temperatures may be close to or below freezing at start-up.
