When the lights go out—or when the site demands more than the grid can provide—you quickly discover just how critical reliable power really is.

For tradespeople, the downtime caused by unreliable or underpowered equipment can delay projects and eat into earnings.

For homeowners, a sudden power cut can disrupt heating, refrigeration, and even home security.

And for rural settings or mobile businesses, access to mains electricity isn’t always guaranteed.

A quality petrol generator bridges that gap—keeping essential systems running, tools in action, and peace of mind intact.

But choosing the right model isn’t always straightforward.

Power output, socket options, mobility, noise, and runtime all need to be factored in.

So, which one fits your needs best?

Below, we break down four standout petrol generators—highlighting their strengths and ideal applications to help you make a confident choice:

• Victor 6.5kW Petrol Generator – LC8000DCS

Best for heavy-duty sites, farms, and home backup needing high power and portability.

• GPG 6000E HD Petrol Generator

Ideal for trades and industrial use requiring stable voltage and long runtime.

• Draper 6000W Petrol Generator

Suited for general site work and domestic backup with rugged reliability.

• Victor 3.7kVA Petrol Generator – 208cc Engine

Perfect for light-duty tasks, emergencies, caravans, and mobile use.

Side-by-side features and applications for confident generator selection.

Victor 6.5kW Petrol Generator – LC8000DCS

Best for: Heavy-duty on-site or backup power where performance and mobility matter.

The Victor 6.5kW generator is built for demanding use across job sites, farms, and homes.

Its high 6.5kW output means it can handle power tools, heating systems, and appliances with ease.

It also includes dual voltage sockets—handy if you’re switching between 110V tools and 220V systems.

Startup is easy with both electric and recoil options, and it can run for up to 8 hours on a 25L tank.

The integrated trolley kit ensures portability across uneven terrain, while the 420cc engine delivers reliable power even under pressure.

Key strengths:

• Dual start (electric/recoil)
• 2x 110V and 1x 220V sockets
• Rugged open-frame build
• Long runtime (8 hrs)
• 77 dBA noise level—suitable for outdoor use

Common questions answered:

Can this run my entire house?

While it can’t power every appliance simultaneously, it will comfortably handle essentials like lighting, refrigeration, and central heating pumps during an outage.

Can it be used indoors?

No. Like all petrol generators, it must be operated outdoors or in well-ventilated areas due to the risk of carbon monoxide poisoning.

Is it difficult to move?

Not at all. The built-in trolley kit allows for surprisingly easy transport despite its robust size.

Does it need assembly?

Only minimal setup is required—typically fitting the wheels and handles, with clear instructions provided.

GPG 6000E HD Petrol Generator

Best for: Trades or industrial use where stable voltage and long runtime are vital.

The GPG 6000E HD from FF Group offers a 6.0 kVA power output and automatic voltage regulation (AVR), making it a strong choice where sensitive electronics or steady current is needed—like for site lighting, battery chargers, or computerised equipment.

Its Euro 5 engine balances high performance with lower emissions, while the anti-vibration system keeps it running smoothly.

A generous 28L tank provides up to 9 hours of runtime.

Electric start, multiple outlets, and added features like overload protection make it suitable for even the toughest jobs.

Key strengths:

• Euro 5 low-emission engine
• AVR for consistent power
• 28L fuel tank – 9 hrs runtime
• LED work light for low visibility
• Overload and low oil protection

Common questions answered:

Can this power sensitive electronics?

Yes. The built-in AVR ensures stable voltage, making it suitable for devices like computers, TVs, and charging equipment.

How long can it run on one tank?

Approximately 9 hours, depending on the power load—a major plus for extended workdays.

Is it easy to start?

Absolutely. It features both electric and recoil start for quick activation in all conditions.

Does it come with a warranty?

Yes, it includes a two-year professional-use warranty for added peace of mind.

Draper 6000W Petrol Generator

Best for: General site or domestic backup use with reliable, robust construction.

Draper’s 6000W generator strikes a solid balance between power and portability.

Protected by a steel tubular frame with anti-vibration mounts, it’s made to withstand daily use in tough conditions.

It delivers 110V and 230V power plus a 12V DC output—suitable for tools and battery charging alike.

Electric and recoil starts ensure quick activation, and its 25L tank offers 8 hours of runtime at 75% load.

Included accessories like a spark plug wrench and DC lead add convenience out of the box.

Key strengths:

• Draper reliability with rugged build
• 110V / 230V / 12V sockets
• 8 hrs runtime at 75% load
• Includes starter tools & accessories
• 85kg – mobile with large rubber wheels

Common questions answered:

Is this suitable for both work and home backup?

Yes. Its dual voltage output and durable construction make it versatile for site tools or home essentials.

Does it come with everything needed to get started?

It includes a spark plug wrench, screwdriver, and 12V charging lead—so you're ready to go straight away.

How portable is it?

With two large rubber wheels and a sturdy frame, it’s mobile enough for site use while remaining stable during operation.

Is maintenance difficult?

Basic upkeep like oil changes and filter checks are straightforward, especially with Draper’s clear documentation.

Victor 3.7kVA Petrol Generator – 208cc Engine

Best for: Light-duty or emergency use in domestic or mobile settings.

Smaller and lighter than others in this roundup, the Victor 3.7kVA generator is ideal as a backup at home or for lighter use on site.

With a 2.9kW output and electric start, it’s simple to operate and still offers dual voltage support for flexibility.

Its 15L tank delivers extended runtime, and the wraparound frame makes it easy to transport and protect during use.

At just 42kg, it's far more manageable than larger units and even fits in a car boot or trailer.

Key strengths:

• Compact, lighter weight (42kg)
• 2.9kW output – ideal for home use
