Quiet, clean inverter power — but the premium price is hard to ignore

Is the Briggs & Stratton 030801 PowerSmart Series P2400 worth buying? Yes, if you want a compact, quiet petrol inverter generator with clean power for sensitive electronics and you’re willing to pay a premium for the Briggs & Stratton badge and CO safety features. At £805.66, it is expensive for a 2400W-class portable generator, but the current price is also the all-time lowest, which makes this a better buy now than it has been at any point in the available price data.

What do you get for £805.66?

The headline figures are straightforward: a 79cc OHV petrol engine, 2400 starting watts, and 1800 running watts. That puts it firmly in the portable inverter category rather than the larger site-generator class, so the real appeal is not brute force but usable, stable power in a compact package. Briggs & Stratton says the inverter technology produces smoother output, which is the key reason this model can safely recharge and power sensitive electronics such as laptops and smartphones.

The feature set is also practical rather than flashy. You get two 230V household sockets, one 12V DC charging outlet, and two 5V USB ports, which gives it enough flexibility for mixed loads: lighting, phone charging, small appliances, and basic workshop or camping equipment. The 3.8-litre fuel tank is modest, but Briggs & Stratton claims up to 8 hours of continuous operation at 25% load, which is a useful runtime figure for overnight backup or a long day of intermittent use.

How quiet is it in real use?

The quoted 58dB operating volume is one of this generator’s biggest strengths. Briggs & Stratton describes that as quieter than a normal conversation, and that matters if you plan to use it on a campsite, in a garden, or near a workshop where noise quickly becomes annoying. The Quiet Power Technology also automatically adjusts engine speed based on the items being powered, which should help reduce both noise and fuel consumption when you are not drawing much load.

That combination of inverter design, automatic speed adjustment, and a 58dB rating makes this far more civilised than a conventional open-frame petrol generator. It will not disappear into the background, but for a petrol unit with 2400 starting watts it is clearly aimed at buyers who want less disturbance and better efficiency. The trade-off is that you are paying a lot for quiet operation and cleaner output, rather than maximum output per pound.

Is the power output enough for camping, backup, or tools?

The 1800W running figure is the number that matters most for day-to-day use, and it defines the limits of the machine. It is suitable for modest combined loads, such as charging devices, running lights, and powering smaller appliances, but it is not a substitute for a high-output construction generator. The 2400W starting figure helps with short surge demands, but you still need to plan around the 1800W continuous limit.

For camping and emergency backup, that is often enough. For workshops or building sites, it depends on what you expect to run. The generator’s clean inverter output is a big plus for electronics, but the overall wattage is still relatively restrained compared with bigger site machines. If you need to run power-hungry tools, heaters, or multiple heavy appliances at once, this is not the right class of product.

Is the build quality worth the price?

The build looks focused on portability and safety rather than rugged industrial output. The compact design and lightweight positioning are strong selling points for anyone who needs to move the generator frequently, whether that is from van to campsite or from shed to garden. The CO Guard Carbon Monoxide Shutdown adds an important layer of protection, and that is a meaningful feature for emergency or semi-enclosed use where safety matters as much as output.

What you are paying for here is not just the wattage, but the overall package: inverter smoothness, quiet operation, fuel efficiency, and safety protection. That said, there is no escaping the fact that £805.66 is a high entry price for 1800W running power. If your priority is maximum watts per pound, alternatives below are much cheaper.

How does it compare to cheaper alternatives?

The most obvious comparison is the maXpeedingrods 3300W Portable Inverter Generator at £482.99 with a 4.5-star rating. On paper, that machine offers more output for significantly less money, so the Briggs & Stratton has to justify itself with brand reputation, CO Guard protection, and its compact, quiet inverter design. If you only care about price-to-power, the maXpeedingrods looks stronger.

The AIVOLT 1200W Petrol Inverter Generator is far cheaper at £209.98 and also carries a 4.4-star rating, but it is a much smaller-capacity unit. That makes it a better fit for lighter camping or home-use tasks, not for buyers who want the extra headroom of 2400 starting watts and 1800 running watts. The Power Station 1000W/666Wh unit at £199.99 is in a different category altogether, since it is a rechargeable power station rather than a petrol generator, so it suits indoor-friendly, lower-power use rather than extended petrol runtime.

In short, this Briggs & Stratton sits at the premium end of a compact inverter segment. It is not the cheapest, and it is not the most powerful, but it does combine a respectable runtime, low noise, and clean output in a way that will appeal to buyers who value those traits more than raw value.

Is the fuel economy and runtime good enough?

The 3.8-litre tank and claimed up to 8 hours at 25% load are respectable for a portable inverter generator of this size. That runtime suggests the machine is designed for efficient light-load operation rather than constant heavy demand, which fits the inverter format well. The automatic engine-speed adjustment should help keep fuel use sensible when the load is low.

For real-world planning, the key point is that runtime will fall as load rises. The published 8-hour figure is at 25% load, so buyers should treat it as a best-case benchmark rather than a universal guarantee. Still, for overnight backup, camping, or intermittent use on a jobsite, the combination of a small tank and efficient engine management is practical.

Is the rating strong enough to trust?

A 4.4/5 rating from 91 reviews is a good sign, especially for a product with a premium price tag. It suggests that most buyers are happy with the noise level, portability, and inverter performance, but it is not a perfect score, which usually means there are some trade-offs in value, power, or expectations. The product’s category rank of #129,766 is not especially strong, so it is better viewed as a niche premium buy than a mass-market bestseller.

The review count is large enough to give the rating some credibility, but not so large that every edge case has been smoothed out. That makes it important to focus on the specific use case: if you need quiet, clean, portable petrol power, the rating supports it; if you need maximum output for the money, the rating does not change the price-performance picture.

Final buying take

The Briggs & Stratton 030801 P2400 is best understood as a refined, quiet inverter generator for people who need dependable portable power and care about clean output, low noise, and safety. It is less compelling if your main goal is to get the highest wattage for the lowest price.

The current £805.66 price is hard to swallow, but because it is also the all-time lowest recorded price, this is the most sensible time in the available data to buy it. If you want a petrol inverter generator for camping, light backup, or electronics-friendly power and you value the CO Guard shutdown and 58dB operation, this model makes sense. If you need bigger output or better value, the cheaper maXpeedingrods and AIVOLT alternatives deserve a closer look.
