Product Details

At Excel Power, we don’t believe in standing still. When we launched the XL4000i, it quickly became our best-selling unit, praised for its reliability, power-to-weight ratio, and sheer versatility. However, we listened to your feedback, analysed the needs of modern off-grid enthusiasts and professionals, and went back to the drawing board.

The result? The Excel Power XL4000ii.

This isn’t just a minor tweak; it is a comprehensive upgrade. The XL4000ii takes the foundation of its predecessor and adds a suite of premium features including electric start, remote key fob operation, an automatic choke, and 2-wire remote start capability, all housed in a redesigned, ultra-tough external case. Whether you are looking for a reliable camping generator or a robust petrol generator for the job site, the XL4000ii is the new gold standard in portable power.

Key Features

When you are out in the field, “enough” power is rarely enough. The XL4000ii is a true 4kw generator designed to handle heavy lifting. While many units in this class struggle with the initial “surge” required by high-draw appliances like air conditioning units, power tools, or circular saws, this petrol inverter generator provides a massive maximum rating of 4500W.

For sustained use, it settles into a rock-solid continuous rating of 4000W. This ensures that you have the headroom to run multiple appliances simultaneously without the fear of overloading the circuit. It is the muscle you need, delivered with the refinement you expect from Excel Power.

Not all power is created equal. Standard open-frame generators can produce “dirty” power with harmonic distortion that can fry the delicate circuitry in your laptop, smartphone, or modern LED television.

The XL4000ii is a premium inverter generator, meaning it uses advanced electronics to “clean” the electricity. The result is a pure sine wave output that matches (and often exceeds) the quality of the power coming out of your wall sockets at home. This makes it the perfect camping generator for digital nomads, photographers, and anyone who refuses to leave their tech behind when heading into the wild.

The days of wrestling with a recoil cord are over. The XL4000ii features a seamless electric push-button start that fires the engine into life instantly. But we didn’t stop there.

  • Remote Key Fob Start/Stop: Imagine being tucked away in your caravan or tent on a cold morning and needing power. With the included remote key fob, you can start or stop your Excel Power generator from up to 10 meters away.
  • Automatic Choke: No more fiddling with levers; the intelligent engine management system handles the fuel-to-air ratio automatically, ensuring a first-time start every time, regardless of the temperature.
  • 2-Wire Remote Start: This is a gamechanger for off-grid solar users. The XL4000ii can be integrated into your power system via a 2-wire start, allowing it to be started from a wired remote connection.

Sometimes, your power needs grow. Instead of investing in a massive, heavy industrial unit, the XL4000ii offers parallel connectivity. By using a simple parallel cable (sold separately), you can link two XL4000ii units together. This allows you to pull nearly twice the power output while maintaining the portability and fuel efficiency of two smaller units. It’s the ultimate flexible power solution for large events or heavy-duty mobile catering.

Despite its impressive 4kw generator output, we’ve ensured the XL4000ii remains a true suitcase generator in spirit. We’ve upgraded the external casing to be tougher and more impact-resistant than ever before. To make transport effortless, we’ve integrated extendable handles and heavy-duty wheels. Whether you’re navigating a gravel driveway or a grassy campsite, moving your power source is no longer a two-person chore.

We understand the frustration of carrying a bag full of adapters. The XL4000ii is designed specifically for our customers. It features one UK standard 3-pin socket, allowing you to plug in household appliances directly.

Additionally, we have included one 32A 240V (Blue socket). This is a vital feature for caravan owners and tradespeople who need a secure, high-amperage connection that won’t overheat or trip under heavy load. It’s professional-grade connectivity in a portable package.

The XL4000ii is as kind to your wallet as it is to your electronics. The 6-litre fuel tank provides impressive run times, but the real magic happens with the Eco-Mode.

When engaged, Eco-Mode allows the engine to vary its revolutions based on the load being drawn. If you’re only charging a phone, the engine will drop to a whisper-whisper-quite idle. If you turn on a kettle, it ramps up instantly. This smart throttle system significantly extends the time between fill-ups, reduces noise pollution, and increases the overall lifespan of this exceptional petrol inverter generator.

When you buy an Excel Power product, you are investing in a partnership. The XL4000ii comes with a 2-year warranty backed by our rigorous engineering standards.

We are proud to partner with Hampshire Generators, providing you access to expert servicing options, technical advice, and genuine spare parts. You aren’t just buying a piece of hardware; you are securing reliable power backed by the best in the business.

Here is what you get; 1 x Excel Power XL4000ii generator, 1 x user manual plus tool kit.

*Please check the output of the generator is high enough for your needs. Some items have a very high starting current (such as motors) so please make sure it is big enough to handle everything you want to power from it. 

Hampshire Generators can also maintain your generator with a regular cost-effective service plan or one-off visit. Simply call 01329 722390 or inquire via the contact us page
