Böhmer-AG W4500i

Advanced Technology Only

Using a portable generator is not an optional thing sometimes but it can get pretty pricey considering how much fuel some models take. However, there are, as always, more efficient and, thus, budget-friendly alternatives out there. Today, we present one such model in the form of the Böhmer-AG W4500i Petrol Inverter Silent Generator.

This generator is equipped with a modernised copper wound motor, which means it uses fuel extremely sparingly. All the while, the Böhmer-AG W4500i delivers performance on par with the high-end models. That way you save money on petrol and get enough power to run plenty of appliances. You might be wondering what the catch is with that kind of motor at your disposal. Well, the engine here is very particular about what kind of fuel it takes and using anything else might damage it. It’s not that big of a deal but it does require a bit of attention lest you ruin your generator by accident.

On the bright side, the modernisation of the motor has allowed for substantially reduced emissions. That way those seeking an eco-friendly option can use the Böhmer-AG W4500i as a sort of middle ground. After all, it manages to offer the kind of power only petrol engines guarantee and yet it doesn’t pollute the air all that much.

Review of Böhmer-AG W4500i Petrol Inverter Silent Generator

The Pros Keep On Coming

With all the praise we’ve sung to the Böhmer-AG W4500i’s motor, you might be thinking we’re out. However, we have yet to mention how quiet this generator is. Yes, indeed, though this model uses a 4-stroke engine with some kick to it, it’s about as close to silent as possible. Even at 75% load, you won’t hear anything more than a steady hum at most. Combine this with the camo paint on the body of the generator and this could make for a great piece of hunting equipment. You could spend a night in the forest with this model keeping you warm or helping you cook without any noise scaring off animals.

Speaking of spending time with the generator, at that level of load, a full 4-litre tank of fuel will last you 6 hours, more than impressive. But that’s just another bonus of a petrol-conserving motor. What’s impressive in an entirely different way, though, is the 1900 W max power output. It should be enough to sustain a whole household should the central grid go out, which is not something every generator is capable of.

As you can already tell, the Böhmer-AG W4500i is a great option on all fronts aside from a few minor quirks. If you have access to the specific kind of fuel this model uses and can afford its above-average price tag, this is a great choice. It has plenty of power, works quietly, and keeps pollution low, offering up a well-rounded product in the end.

ALLPOWERS 372Wh

A Reliable Powerhorse for Off-grid Adventures

Portable generators are great for many outdoor events where you have no access to the grid. Since we take our mobile gadgets anywhere we go, a portable generator will keep you connected wherever you are and is an irreplaceable source of power when in the wild. So, if you are in search of a reliable power companion for your outdoor trips and journeys, take a glimpse at this mobile power station from ALLPOWERS.

To start with the power output, it is an electric model packing an impressive capacity of 105000 mAh or 372Wh, which is great for pretty much any electronic devices with the rated power below 300 watts. In practice, it translates to anything from laptops, tablets, smartphones, TVs, and cameras to lanterns, lamps, and even mini-fridges so much favoured by campers. Notably, a premium high-density Li-ion battery boasts quiet operation and ensures consistent power output. Meanwhile, Pure Sine Wave technology makes the generator compatible even with sensitive modern electronics.

With the runtime of up to 4 hours (at 50% load), the generator itself can be charged directly from the mains, from your car using a 12V adapter, or from a solar panel via the MC4 Anderson connector cable. Hence, if you travel by car or have a portable solar panel (which is often a common thing for avid outdoorsmen), juicing up the generator won’t be a problem. The only gripe you might have is a longer time needed to recharge the battery to the full, which takes up to 7 hours. However, even a half charge will be enough for many of your needs when away from the grid.

With Smart Controls

When it comes to connectivity, this ALLPOWERS generator features as many as six types of outputs including two 12V/15A DC outputs, three fast-charging USB ports, a Type-C output, two AC sockets, and a 12V cigarette lighter socket. Besides, it comes fitted with the QI standard technology that allows for wireless charging of QI-enabled devices.

Yet, what really sets this generator model apart from many rivals in terms of controls is the app-managed control system ensuring the convenience of remote unit control. Thanks to the built-in Bluetooth module, you’ll have a chance to wirelessly connect to your generator via a special AiPower app available for both Android and iOS. This way, you can constantly check the remaining battery level, output and input power, and even turn the sockets and ports on and off. The app syncs with the unit like a charm and the Bluetooth provides for a solid and reliable connection.

To put it in a nutshell, as powerful, versatile, smart, and functional as it is, the ALLPOWERS 372Wh generator is hands down the best choice for camping, hunting, fishing, tailgating, or RV travelling.

BEAUDENS 166Wh/52000mAh

Best for On-the-go Use

Though claimed to be portable, many generators of this kind appear quite heavy in practice, especially those petrol power-horses. And what if you need a really small and light model you’ll be able to carry in hands? This is where the BEAUDENS generator will come into play.

At 22 x 8 x 16.8 cm dimensions and weighing only 2.2 kg (which is half of the weight of most common electric models), the unit is one of the most portable models you can find around. Despite that, it's not a flimsy thing. The robust aluminium shell makes it damage-proof and fit for both for indoor and for outdoor.

The BEAUDENS generator is no slouch in terms of power as well. The 52000 mAh battery packs enough punch to power most common electric and electronic devices. With the maximum rated maximum power output of 200 watts, it can function as a huge power bank to recharge your devices or can be used to continuously run some electric appliances. Overall, the battery capacity will be enough for about 11 smartphone charges, 7 tablet charges, and 2 or 3 full laptop charges for running the lights or some devices up to 3 hours, which are quite impressive rates for a mini generator like this.

In the meantime, the generator battery offers three charging options, including AC power, car charging, or a solar panel. The AC adapter and car charger come included, while a solar panel can be bought optionally.

Review of BEAUDENS 166Wh/52000mAh Portable Power Station

Advanced Battery

Fitted with AC, DC, and USB outputs, the BEAUDENS generator is good for powering and charging all sorts of devices. However, the thing that's the most important when it comes to electric generators is the battery, and the BEAUDENS is good here too. The unit is featured with a LiFePO4 battery, the advanced lithium iron phosphate model which is widely used in the electric bus industry and distinguished by enhanced reliability, flawless performance, excellent safety, and prolonged service life. Thanks to this, you can expect it to handle up to 2,000 charge and discharge cycles and last up to 10 years, with no reduction in charging ability.

To conclude, though not a power beast, the BEAUDENS is a true winner when it comes to power-to-size ratio. Compact size and decent power output make it a real find for campsites, emergency situations, and outbuildings or sheds with no electricity access. Besides, it's quite affordable, which makes the offering even more attractive.

What Is a Portable Generator?

Nowadays, the mankind can barely exist without electricity. Every day we use scores of electrical appliances, such as a fridge, cell phone, computer, etc. However, what if some accident happens and the power supply is off? Some areas in the world are particularly prone to earthquakes, which means power outages are highly likely. And that's why the best solution is to have a portable independent power source that will help you generate electricity and power your house. Such power sources are called portable generators and they are used everywhere electricity is needed. 

As the name suggests, those models stand out for portable design and can be easily transported or carried around when needed. Basically, they are divided into gas-powered units and electric ones built around rechargeable batteries. While petrol generators pack a lot more power to feed just about any electric device, eco-friendly electric models will best suit for lower power appliances. In the end, everything will depend on your needs. 

If you wish to light your yard without using electricity, get one of the solar lights from our brand-new review. And if you like camping and picnics, you will certainly take advantage of a camping stove.

What Features to Compare

When you try to pick out the best portable generator for a home or a trip it’s important to know just a few key characteristics. While the range of models available is huge, the main differences lay in these parameters.

Power Source

First off, see whether the product you’re looking at is powered by fuel or solar energy. The former ones are less environmentally friendly but they are more popular with a broader line-up of models. Plus, solar portable engines are less powerful as they are a relatively new step in the technology’s evolution. For now, a petrol generator seems like the most viable option, so we picked out the best 5 of them that we could find. You can also search for a portable battery-powered generator. Though those are less effective for high power needs, they work excellent where true portability is needed and are the best choice for the use in RVs, camping, hunting, fishing, and any other outdoor activities and/or events.

Noise

Next up is the factor of noise. If you want a generator to keep in your yard or just for small camping parties, you’d probably require one that didn’t make much of a ruckus. This parameter is often omitted from the product descriptions but you should still check for it just in case. Reading reviews, such as ours, also helps to find the important characteristic. Thus, unlike petrol generators driven by roaring engines, battery-powered models are usually less noisy.

Power Output

Obviously, you have to take into account the power output which is what you’re buying this product for in the first place. The smallest models might make around 600 W, which would be enough to sustain a microwave oven or refrigerator or, alternatively, a couple of laptops, which seem to be just as essential nowadays. For higher power needs, choose one of the gas generators with power outputs ranging up to 2000 watts.

Compatibility

It’s essential to check for the number and type of the generator outputs that will determine what devices and how many appliances you’ll be able to connect. DC, AC, and USB ports are a must to connect both common plugs and USB-enabled units. Some modern models even offer wireless charging options for recent smartphone models.

Inverter Generator

Finally, make sure to see if the model is an inverter generator, which is safer for your electronics, makes less noise, and can give you power as you need it without operating constantly and wasting fuel. Pure sine wave technologies applied in some models make them safe even for sensitive electronic devices.

Did you know?

What You Need to Know When Running a Generator

Portable generators are handy backup sources of power for camping trips, electricity outages, or running electronics away from a power outlet. But even the sturdiest of them need occasional maintenance, which may be tough to do without any prior knowledge. So here are some handy tips on what you need when working with these machines.

First off, let’s do the obvious and save some time by making sure the product you’re choosing has a good warranty. The five that we’ve picked out for you have warranties of 1+ years, more than enough to make sure everything is set up and running properly. Plus, even if something goes wrong, you can always fall back on the warranty to help you with any damage to the generator that you can’t get rid of on your own.

Check up on Oil and Fuel

Next up, always remember to change oil regularly and keep some backup oil and filters on hand at all times. Just having a couple of them in storage will save you a cumbersome trip to a store if you get caught in an outage with no backup filters or oil. With a portable generator, a couple of minutes of preparation can prevent hours of unnecessary maintenance and repairs.

The next tip is twofold and both parts are important. Number one is to keep your fuel tank filled up when running it for long periods. You don’t want your generator to run out of power suddenly and leave you in the darkness, fumbling with a canister of petrol. Number two, strangely enough, is to drain the fuel tank completely. Of course, you should drain it after you’re done with the generator and before you store it somewhere until the next emergency. It is usually recommended to remove gasoline carefully, perhaps with a vacuum syphon, and then run the engine briefly until it uses up whatever little fuel is left and shuts down. After that, it should be okay to put the engine away until later use.

Follow the Proper Start-Up and Shutdown Procedures

Also, essential to your safety, do not start refuelling a generator after you’ve just used it for hours. The engine in such a machine, like all others, tends to get quite heated. Mixing easily combustible petrol and scalding engine parts is not a great decision, especially when you’re in an extreme situation like a power outage. Just wait for 10-15 minutes until the machine cools and proceed with refuelling.

Another tip, usually advised by the manufacturers themselves, is to start the generator every month or two, just to make sure it’s running smoothly and nothing is broken or damaged. That way you will not be caught unawares when a storm takes out your electricity and you try to start the engine in the night only to get a bit of sputtering and no power. This rule is something that a lot of people seem to ignore, but this five-minute easy process is vital to keeping your generator running smoothly.

And, lastly, remember to read up on generators and pick out the model carefully. A backup source of power is not a one-second buy and, before you get something so important, you should make sure it’s up to your electricity needs and meets the safety and quality standards. Of course, we’re here to help you out and the above product guide should be of some help.

FAQ:

Q: Why do I see two different wattage amounts in the characteristics?

A: The rated wattage is how much power your generator can give you constantly and with no interruptions. This means that it should support any appliance that requires this wattage with no issues. Maximum watts are the number that the engine can give out for short periods only, like bursts of energy. This is important for electronics that might need more power when they start up or operate at peak speeds. So, make sure to check both levels and see if they can support whatever electronics you plan to power.

Q: Is it safe to use a portable generator during a power outage or a natural disaster?

A: A power outage is actually one of the main situations where you might need one but make sure you have it fueled or charged up before it happens.

Natural disasters such as earthquakes, hurricanes, or flooding may cause electricity failure, but if you’re in a safe place such as a shelter or reinforced basement, you can still use a generator as long as you protect it properly and keep it out of an enclosed space. Do not run it inside the shelter or whatever indoor spot you’re in. Make sure that the machine will not be damaged by the disaster or its results. Do not place it in wet areas or anywhere with a chance of debris falling. In short, exercise caution just like you would with any other appliance.

Q: Is it possible to run this machine in an enclosed area like a house or an apartment?

A: No! And it is actually dangerous. These powerful little engines are designed for outdoor use so that they can take advantage of plentiful natural ventilation. The result of a portable generator operating is exhaust that contains carbon monoxide, which is highly poisonous and could easily fill up a room to the point that it will harm your health significantly. Hundreds of people die every year from carbon monoxide, so be sure to read up on safety tips.

Q: Am I required to ground my portable generator?

A: You should definitely ground it for your own safety because you risk being electrocuted otherwise. Luckily, it doesn’t require anything beyond the standard grounding regulations, and this process is not difficult at all. Just carefully follow the steps and ensure that your experience is safe.

Q: I’ve picked out a generator, but it doesn’t have wheels, how important are they?

A: Well, it depends on how often you will need to move the machine. If it’s lightweight, you can probably carry it by hand with no issues, but a heavier one would likely to benefit highly from a wheel kit.

Q: I have a petrol generator, can I use any other fuel types on it?

A: Most generators have a specified fuel type and, unless you want to risk damaging such an important machine and, possibly, yourself, you should not change the fuel type. Consult a professional or contact the manufacturer to see if it’s possible or not. Also, you can check up on other engines that can even be powered by solar panels.
