A power generator is an important item for emergency preparedness and those living in areas with frequent power outages. It’s also nice to have when camping or to run equipment for home improvement projects. However, purchasing a portable generator comes with a big price tag and it can be difficult to know which ones are really worth the investment.
Our reviews team evaluated a range of portable generators to help you find the best portable generators for your needs.
The 10 best portable generators in UK 2021
1. ALLPOWERS Portable Generator 372Wh
For such a compact portable generator there are a good number of inputs and outputs. These include an AC 220V input to be used with the supplied charger pack, a 12-24V solar power input, and 12V-24V car charger for powering up the device, and a total of 9 outputs. Among the outputs are two AC 220V for standard UK plugs, three USB, and a 12V DC output. There is also a 5V DC wireless charging platform on top of the generator.
The main unit features a nice LCD screen that displays important information like battery level, how much operating time is left, and indicators for USB and in/out. On either side of the screen are small LED lights that could be used for reading if the generator was close to you.
Being a pre-charge type generator, it is obviously very quiet when in operation but there is a little noise coming from it. When compared to a petrol generator though, it is pretty much silent. Fully charging this generator will take about hours and that will give you enough stored energy to charge 20 smartphones, power a mini fridge for 7 hours, or a light for 80 hours or more.
All being said, this is a great piece of kit that would suit active people who need something small and lightweight that they can carry around with them. It’s perfect for hiking, camping, and festivals.
2. Böhmer-AG Camo Petrol Inverter Generator W4500i
Coming in at number 1 on our list of the best portable generators is this Camo Petrol Inverter from Bohmer-AG. This lightweight, camouflage print power pack runs on unleaded petrol, and has a 2000W pull-start copper wound motor, for high power and stability. Efficiency is an important part of this generator; a fuel-efficient inverter reduces fuel consumption by up to 40%, and the economy mode function further cuts consumption and emissions, when switched on.
There are 2 x standard AC 3-pin plug outlets, as well as 1 x DC output, making it suitable for UK use – although unfortunately, there are no USB outlets. The pure sine wave output is uninterrupted, meaning you can charge sensitive appliances such as laptops, without the risk of damaging them. This claims to be one of the quietest generators on the market, and is rated at 59dB. While this is fairly good for a fuel-powered generator, it’s by no means silent, so bear this in mind when choosing a petrol generator – especially if you’re going to be using it on campsites.
Overall, when you take into account the high power, long running time and comparatively low noise output, it’s clear that this is one of the best portable generators on the market at the moment. It may not be the cheapest option, but it’s worth it.
3. Briggs & Stratton P2400
The Briggs & Stratton P2400 is equipped with a highly-efficient 306cc engine and capable of generating up to 5,000 running watts during 14 hours at 25% load. This model features a recoil start and a low-oil shutdown capability. The advanced inverter technology and a noise-reducing shell contribute to the 60% quieter operation in comparison with a traditional generator which amount to 66 dB at 25%.
This portable inverter generator is compact but quite heavy in comparison with similar models in this class, but it weighs 138 pounds, which makes it heavier to lift in and out of vehicles. This unit comes in an ergonomic design with its luggage-style telescoping handle and sturdy wheels which enhance its maneuverability. Besides, there are four regular outlets, two USB ports, and one 120-240V locking outlet which grant you an opportunity to energize several electronics at the same time.

6. BEAUDENS Portable Power Station 166Wh/52000mAh
This is the first lithium iron phosphate battery portable power station sell on amazon. Beaudens have a series portable power station, each one equipped with LiFePO4, which have several advantages over the lithium-ion battery.
LiFePO4 has excellent thermal and chemical stability. This battery stays cool in higher temperatures. It is also incombustible when it is mishandled during rapid charges and discharges or when there are short circuit issues. LiFePO4 does not normally experience thermal runaway, as the phosphate cathode will not burn or explode during overcharging or overheating as the battery remains cool.
However, the chemistry of lithium-ion does not have the same safety advantages as lithium iron phosphate. It’s high energy density has the disadvantage of causing the battery to be unstable. It heats up faster during charging as a lithium-ion battery can experience thermal runaway.
Another safety advantage of LiFePO4 involves the disposal of the battery after use or failure. A lithium-ion battery made with lithium cobalt dioxide chemistry is considered a hazardous material as it can cause allergic reactions to the eyes and skin when exposed. It can also cause severe medical issues when swallowed. So, special disposal considerations must be made for lithium-ion. On the other hand, LiFePO4 is non-toxic and can be disposed of more easily by manufacturers.

10. Jackery Portable Power Station Explorer 240
This power station makes use of quite of few things that you simply wouldn’t have with a regular power bank and goes beyond charging, and on top of all that, there’s a lot of power capacity to be used.
The power capacity of this Explorer 240 power station is 67,200mAh, or you can basically just translate that into 240Wh, as that’s in the name of the power station. So this is a lot of power capacity, and even when it’s converted during usage we still think that there’s going to be a lot to use.
Thankfully the power station makes use of a handle that makes it a lot easier to carry about but overall, you’re always going to be setting this power station down in order to use it. You can, of course, take it anywhere that you want, place it in your car, carry it around or store it in your house for emergencies, but when it comes down to it, a power station is meant to be set down and this one is no different.
How to choose the best portable generators
With so many options out there it’s easy to feel overwhelmed, but that’s why we want to give you the features to consider and what to look out for.
Prices can vary drastically when it comes to portable generators. Typically the price point will affect the amount of energy the generator produces and the length of time it will last (although this isn’t 100% the case, just a general guideline).
You can pick up a portable generator for under $200, or you can spend well over $1,500 on one. With such a wide price spectrum unless you know what to look for and what will satisfy your needs you may not have a clue what to go with. You don’t want to buy an inexpensive generator only to find it doesn’t power the equipment you want to run, and at the same time, you don’t want to overpay for a generator that offers more power than you’ll ever need.
So as you go over the other points of importance make sure to keep in mind the price and what you can afford.
2. Energy Source
Every generator has an energy source. Many generators will use regular gasoline (the same gasoline you purchase at a fuel pump). However, others might run off of diesel, while a handful will use propane. Diesel fuel costs more than regular gasoline, yet it often burns longer and gives you more energy per gallon. Of course, if you’ve been around diesel engines before you know it creates a unique odor. It also requires additional maintenance to keep it running.
Whatever you end up going with, it’s important to keep in mind how the generator creates the energy.
3. Power Production
The amount of power a portable generator produces (and the length of time it can output the electrical current) is important. You may want a portable generator to work with an electric grill or television at a tailgate. Or you may want it to power large lighting rigs and construction equipment. The amount of power the generator creates is critical.
You should have a basic idea as to what you want to use the generator will. Do you want to use it to power some basic handheld electronics, or do you want it for a specific job? Keep all of this in mind when you’re looking for the right generator.
Lastly, keep in mind the size and the weight. If it’s just you and you want a portable generator, you may want to go with something smaller that you can carry on its own. However, if you’re working with a team and have the vehicle capable of moving it, something larger may be just right. After all, you probably don’t want to buy a 75-pound generator pre-fill-up and not have the ability to move it (or the vehicle to secure it in).
Overall, portable generators are helpful in different circumstances to ensure adequate power supply in your home, activities, or your business premises. With our comprehensive guide and analysis, finding a suitable portable generator for home, RV, camping, or even for the job site should be an easy task. Our portable generator reviews feature only the top selling and highly rated ones from the best brands. We’ve analyzed the features and benefits of each of these units.
