To sum up, the Genmax GM1600iBC is a quiet, compact and lightweight portable inverter generator tailored for:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • DIYers who wish to improve their efficiency with tools

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The Genmax GM1600iBC in use

The Genmax GM1600iBC

The Genmax GM1600iBC's engine, 57 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1,200W and reaches a peak wattage of 1,600W. In addition, the parallel capability (parallel kit not included) empowers doubling of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

With a noise rating of 58 dBA (less noisy than a conversation at home), the inverter generator features a standard recoil pull-rope starting mechanism.

The fuel capacity of 0.63 gallon allows the GM1600iBC to operate for around 6.5 hours at 50% load with a full tank (fuel consumption around 0.1 GPH).

Thanks to its low <3% Total Harmonic Distortion (THD), the GM1600iBC produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.


The control panel features 2 AC outlets as follows:

Duplex 120V 20A (5-20R)

Moreover, it comes equipped with 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.


As the Genmax GM1600iBC is an inverter generator, its encased design (L17.1 x W9.6 x H15.7 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

Weighing just 25.4 lbs, the GM1600iBC can be considered a lightweight portable generator. The generator can be moved with ease by only one person and so it can be enjoyed on-the-go. With its handle (molded in the case), carrying it becomes a breeze, adding to its convenience.

Good to know: This unit ranks 7th in our list of the 10 smallest portable generators.

The GM1600iBC's control panel

The light indicators show you if the generator is on overload, the generator is ready and the oil level is too low.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

It also benefits from Genmax's CO DETECT technology, which is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

In addition to the traditional documentation and an owner's manual to help you get started promptly, the Genmax GM1600iBC also includes several accessories: funnel and tool kit.

The Genmax GM1600iBC versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM1600iBC compare to inverter generators of similar power (between 1000 and 2000 W).

  • Concerning weight, the Genmax GM1600iBC weighs only just 25.4 pounds, distinguishing itself as one of the lighter inverter generators amidst the 1000 to 2000 rated wattage range. In terms of weight, one of the champions in their power range is the Pulsar PGD16iSCO, standing at just 24 lbs.
  • When comparing it to devices with a similar running wattage, this inverter generator's lowest noise level of 58 dBA puts it alongside the noisier units. If noise level is one your key decisive factors, you may find the Honda EU2200i appealing. It's rated at 48 dBA, making it one of the quietest generators in its power range.
  • At a 50% load, the GM1600iBC's around 6.5 hours of runtime on a full tank fall within the average autonomy range for similarly powerful inverter generators. If prolonged run time is essential to your needs, you could consider the Westinghouse iGen2200, which offers one of the highest autonomy among devices with similar power output, lasting around 10 hours.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. This inverter generator provides better fuel efficiency than most others in its wattage range, consuming approximately 0.1 GPH (gallon per hour) at 50% load. If fuel consumption is your top priority, we suggest to check out the Pulsar PGD16iSCO, which has a fuel consumption of only 0.09 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 1000-2000W inverter generators, the Genmax GM1600iBC is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
