Best Portable Inverter Generator Review 2019-2020

What is an Inverter Generator and what are its advantages?

An inverter power generator is expressed in UK, an inverter. A normal inverter is a device that converts DC voltage into AC voltage, ie energy – in this case electricity – from a fixed DC power source (mostly batteries and / or solar panels) uses and transforms this DC voltage into an AC voltage by means of electronic circuits. The output voltage can, as needed, take on almost any desired height. The normal case for normal consumers are 230 V / 50Hz.

Inverters are electronic components that produced by a converter-generator, take power, filter and bring in an absolutely pure sinusoidal flow.Unfiltered power from a converter, such as that found on many models of the red Kipor or OEM generators, involves extreme voltage spikes and fluctuations. These tips are capable of destroying sensitive equipment in no time. Many manufacturers have now included in their warranty conditions that the operation of your device to a generator without inverter technology, the warranty expires.

For this reason, all of our gasoline generators now come exclusively with inverter technology – no matter whether it is FME, Voltherr, Atima or even Kipor devices. 
In a conventional converter generator without inverter technology occur fault voltages of up to 23%. With an output voltage of 230 volts, your device will have short-term voltages of over 280 volts. The slow but sure death for most electrical appliances.

The following devices are just a short extract of those that rely on an inverter in order not to be destroyed.

  • TV, computer, screens, radio, stereos, music amplifiers, gauges, satellite receivers
  • some makes of refrigerators
  • RV Chargers that use the grid frequency for control
  • Compressors for air conditioners and refrigerators in motorhomes
  • Mains frequency controlled chargers for expensive video cameras, cell phones, cameras, etc.
  • microwave ovens
  • Induction cookers etc.

The list can be continued indefinitely. There are only a few electronic devices that do not rely on a pure sine wave voltage, such as motor chain saws, drills without speed controller or older angle grinders. A generator with inverter technology is the best choice to cover a wide range of applications with the rapid development of advanced technologies.

What makes an inverter generator still convincing?

Clearly through its weight and its mobility.

Most inverter power generators are extremely small, compact and lightweight compared to their power. Most inverter power generators can be carried like a suitcase – many are also directly provided with rollers, which is very important for mobility. As a rule, Inverter generators weigh between 10 and 35 kg. If you need a device for professional use or as an emergency generator for a whole house, the weight is still under 100kg and the generator is on wheels, which makes it very easy to move even at the place of use. Due to the flexibility and mobility of the Inverter generators, these can be easily transported and used for a variety of applications such as excursions, boat, RV, camping, allotments, festivals and many more.

By contrast, conventional generators are available in almost every size (compared to inverter generators). The focus of the conceptual design of the Inverter Generators is to make them as flexible and mobile as possible. Thus, these are usually very easy to transport (by low weight, an existing trolley or wheels) and compared to the open-frame converter generators very quiet.

Is there really only gasoline inverter power generators or diesel inverter power generators?

In general, there are “actually” only gasoline inverter generators! But of course there are exceptions, as everywhere else. At GmbH you will find, for example, the FME XG-SF 5600D or the Kipor ID 6000. These two generators are diesel inverter power generators. The performance of these inverter power generators is significantly higher than the performance of small gasoline inverter generators. These deliver a power of 5600 – 6000 watts and can thus supply a complete apartment building as an emergency generator. Therefore, many homeowners use the offer of the diesel inverter power generator, in order to secure their house in the event of a power outage.

Particularly noteworthy here is that the legislature allows to use fuel oil as a fuel – so in operation so a cost-effective matter.

The big topic: “Volume of Inverter Generators”

One thing in advance: Inverter power generators are usually a lot quieter than a conventional power generator. This is due to your design, because they are encapsulated, which significantly reduces the perceived volume of engine noise. Inverter generators can vary your engine speed according to load (keyword: Eco mode). Therefore, they only produce as much volume as they need right now, and therefore they protect the environment, but also, thanks to their lower consumption, your wallet.

For this reason, an inverter generator is the perfect choice for camping, festivals, allotments and all other places where you want to avoid unnecessary noise. The inverter generators available from GmbH can be safely used in your garden or at the campsite without the neighbors complaining.

Inverter use power generators in the interior? Is that possible?

Inverter Generators and conventional power generators are usually designed for outdoor use. Since internal combustion engines generate life-threatening CO2 and CO during operation, which are also odorless and thus can not be perceived in time, there is an acute danger to life for present living beings when operating in closed rooms.

If you still want to use your generator in closed rooms (garage, caravan, cellar, etc.), a special temperature-resistant exhaust hose must be used to remove the resulting exhaust gases. You get with us both a simply running exhaust hose, as well as a specially-jacketed gas-tight exhaust hose. It is particularly important to note that the seal between the device and hose is really tight and no gas can escape. We have accepted this problem and individually fabricate an adapter piece (adaptation) for each generator type to ensure that no gas escapes there.


The inverter power generator DQ-1200 – the handy powerhouse

The fact that most people like to party and attend music festivals is nothing new. Last but not least, mobile power generators have their big presence everywhere, where people enjoy themselves amidst the public power grid.Admittedly, at festivals with thousands of visitors, the organizers use other power generators than we offer. But also smaller events – z. For example, a celebration with good friends at the gravel pit – live from an adequate power supply. Moody music, cold drinks, etc. are just part of it! On these occasions the reliable inverter power generators from DENQBAR will help you!

To all those who are interested in the clean and quiet operation of electrical equipment, our DQ-1200 is aimed. The inverter power generator has an automatic speed control, which allows a particularly economical operation. The 2.7-liter tank capacity allows up to 6 hours of operation – a long time to ensure the smooth operation of voltage-sensitive equipment (such as computers or music systems).

Our 1.2 kW digital inverter power generator offers you many other useful extras: For example, various automatic shut-off mechanisms, such as oil shortage or overloading, ensure a long service life – so that you enjoy your DENQBAR product after months and years just like the first one Day!

The best emergency generators

Having your own power generator can save you one day or even night. For example, if the power supply fails and the power outlet is no longer providing power to household appliances, lights, or PCs, the backup generator will help. In the present time, however, virtually nothing goes without electricity.

With a power generator (or even emergency generator called) in the household, can be generated in such cases quite easily even electricity. Despite power failure can then continue to work with the emergency generator, read or watch TV.

But such a power generator is not only suitable for emergencies. The generator is also used for working with electrical tools in remote locations without connection to the mains.

Although extension cords may be a solution in such a case, they sooner or later reach their limits. But with your own electricity generation directly on site via a mobile emergency generator, there are no limits to the field of application of your power tools. Also on camping trips or garden parties makes such a mobile power generator repeatedly paid.

Particularly important is an emergency generator for hospitals, chemical laboratories or nuclear power plants, as a sudden power failure can quickly become a matter of life and death.Generators for hospitals, of course, are stationary large units that automatically start in an emergency. In contrast, there are mobile power generators, which are needed for private power generation.

So that you can make an informed purchase decision on the subject of emergency generators, we try to give you on this page an overview of the main features of the power generators for household use, which should be considered in your purchase decision.

Generators Test: All about emergency generator

Emergency generator mode of operation

A power generator can be seen as a kind of “mini-power plant”. Different resources (depending on the type of drive motor) are used to generate electricity with the generator. This power is generated by the drive of an internal combustion engine and a generator coupled thereto, which converts the mechanical energy into electrical energy. This combustion engine from the emergency generator can be powered by diesel, gasoline or gas. Power generators are usually started by means of a cable, but there are also emergency generator models with compressed air or electric starters.

Emergency generators are available in many shapes and sizes: handy small appliances as an emergency power solution for the home PC or stationary large power units for chemical companies, nuclear power plants or hospitals. In this article, we mainly focus on mobile power generators that are relevant to the use of craftsmen and individuals.

In general, however, it can be stated that a commercially available power generator for private use is equipped with a 230 Volt connection and thus all common devices with Euro or Schuko plugs can be operated on the emergency generator.

Generator models

The gasoline generator

Petrol as fuel is the most widely used variant of the drive of mobile power generators in private use. In general, a gasoline-powered generator has a high continuous power and has a low consumption. Of course, there are differences between the individual power generator models.Cheap generator models can achieve much worse results in terms of both endurance and fuel consumption than an emergency generator of quality brands. Therefore, before the power generator test and purchase, pay close attention to the information on maximum and continuous power in the product information.

Gasoline generators, however, are often subject to smaller current fluctuations, resulting in lower power quality. This in turn adversely affects technically sensitive devices, such as hi-fi systems or a laptop. Although gasoline engines are not quite as powerful as a diesel-powered generator, but this type of emergency generator is also a bit cheaper and beyond that for use in the allotment garden is usually sufficient.

The diesel generator

With diesel as fuel, a power generator usually provides a higher power. It also allows multiple devices to be connected to the generator at the same time, so that a more powerful use of your generator is more likely a diesel engine. For gasoline generators, in most cases only two devices can be connected at the same time.However, a diesel-powered emergency generator is subject to current fluctuations and therefore not suitable for the supply of sensitive technology.

The inverter generator

An inverter, in simple terms, is an inverter and filters the generated current to obtain a “clean”, sinusoidal end product. An inverter generator can convert direct current into alternating current, generating a constant, sinusoidal alternating voltage with a frequency that is also suitable for the commissioning of sensitive technical equipment. For flat screen televisions, laptops and hi-fi systems, an inverter emergency generator is therefore the best choice, since the generated power quality is very high. Better power quality means longer life of the consumables. With an inverter emergency generator, it works so well with the live broadcast of the football match on a camping trip.

Gas powered generators

Of course, the power generator (ie the internal combustion engine) can also be run on naturalgas and offers an alternative to diesel or gasoline engines. The functioning, with a conversion of mechanical into electrical energy by means of an internal combustion engine and a generator, remains the same. Only gas is used as fuel from the generator. But if you need very high performance from your mobile power generator, then diesel models are likely to be preferred.Otherwise, the power generator variant with the gas operation can be a cost-effective alternative and especially in the field of camping enjoys this also very popular.

Generators purchase criteria

When power generator test and purchase, you should note some important points. It is particularly important that you think about how often and where the emergency generator should be used before the power generator purchase. Depending on the emergency generator application purpose, some criteria are more important than others.

engine type

As already mentioned, you can choose between gasoline, diesel, inverter or butane or propane gas powered generators. Which is most suitable depends on the intended use and the power required for it. Diesel-powered generators have the highest performance, whereas gas generators are very economical.

In the case of technically sensitive devices, an inverter power generator is recommended in any case because this provides the best power quality, in terms of the most constant voltage.Emergency Generator Models with mixed drive, ie which can be operated either with gasoline, diesel and / or gas, are currently not available on the market.

field of use

Before you commit to a power generator, you should be aware of how often or how long in a row you intend to use the generator. Cheaper power generators may be enough if you only want to use the unit from time to time for a few hours. However, if the emergency generator to provide higher performance, so regularly generate power for several hours at a time, then pays the handle to the more expensive power generator brand model with certainty. These are usually much more durable than the savings and make themselves already thereby already paid.

If you want to use the generator mainly at home and in case of a power failure, then you should note that many home appliances are sensitive to the quality of the supplied power. The sound quality of your stereo, PC and TV needs high-quality voltage and a very stable frequency to work efficiently. Here, the above-mentioned inverter power generator is recommended.

For which device types your desired power generator is suitable, depends essentially on 2 factors. First – the already mentioned current or voltage quality. Second, the power of the generator in combination with the consumption of the equipment to be connected (both in watts).The power generator output should generally be well over a third of the consumption in order to guarantee a smooth operation.

In other words, if you plan to connect a very high-consumption device to the emergency generator, with a consumption of z. As 2000 watts, then your generator should at least be able to generate 3000 watts. And that constant, which also represents a non-negligible aspect of the power generator.

In winter, caution is advised when using a generator. Due to the snow and the general wetness that prevails at this time of year, it may well happen that the generator gets wet when it is used outdoors and it short-circuits.

period of use

Before the power generator test and purchase you should inform yourself depending on the planned period of use about the permanent and maximum power of the generator. The maximum power refers to the maximum current output that can be consistently generated by the generator over 20 minutes. The continuous power from the power generator, however, refers to the power generated over a longer period of time. This should be around 90% of the max. Power amount.Whether maximum or rather the continuous power is more important for you, depends entirely on the planned application area. However, the continuous power from the generator is more relevant in most cases.


The generator should just as little be a noise annoyance. Not for you and certainly not for your neighborhood. As a result, the sound level should be within a comfortable range of decibels, and fortunately, many emergency generator manufacturers pay special attention to this fact in product development. Inverter emergency generators are often seen as the silent variant of the generators, but with different soundproofing devices, other generators are quiet. For this reason, please note the sound power level information (in dB) of the power generator you are considering for the emergency power generator test and purchase. In particular, if the emergency generator should be intended for use in their own home, this is a not to be neglected circumstance.

Low consumption

Savings in fuel consumption are of course not only good for your wallet, but also for our environment. Fittingly, power generators are offered with so-called eco-circuits. The engine control automatically adjusts the engine speed to the required power from the power generator. The tank filling of the emergency generator is thus more productive and that pleases in the end both you and mother nature.


It is also important to select the right alternative power generation in relation to the required power. The power is given in generators in VA (volts ampere). While some PCs or computers, for example, with a lower power (less than 300 VA) are operated, there are household appliances and electrical appliances, which suck significantly more from the line. A commercial washing machine often consumes more than 5 kVA (5000 VA). Which electricity supplier you need depends so much on the consumption device that is to be supplied with it.

Size of the device

Of course, the size and the associated handiness of the device for private power generation are not insignificant. How easy it is to transport and store the mobile power generator is of great interest, especially with constant changes in the field of application. Select the power generator, in this case its weight and dimensions, according to your personal needs.

Quality of the output

A supply of high-quality electricity will also extend the lifetime of the connected devices. High quality power supply depends on good regulation of power and voltage. There are different types of control in the emergency generator, each having its own advantages. Inform yourself accordingly before the emergency power generator test and purchase whether the power generator you want has such and above all which control.

Being independent of the normal power grid definitely has its merits. An own power generator in the household makes sense accordingly and he can become the proverbial savior in case of power outages in need.

Advantages and disadvantages of a power generator

Advantages of the generator:

  • Well suited for alternative power generation in case of power failure
