Zoom on the Konner & Sohnen KS 2000iS CO

In summary, the Konner & Sohnen KS 2000iS CO is a quiet, compact and lightweight portable inverter generator especially useful for:

• Tailgating and campground aficionados with the desire of enjoying power anywhere they go
• Handcrafting enthusiasts who wish to work on-the-go

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

The Konner & Sohnen KS 2000iS CO

Running on gasoline, the Konner & Sohnen KS 2000iS CO operates with a 79.7 cc (3.3 hp) OHV 4-stroke engine, delivering 120V, with a running wattage of 1,800W and a peak wattage of 2,000W. Furthermore, the parallel capability (parallel kit not included) offers the advantage of doubling power output when connected to another similar or compatible unit, delivering expanded energy capacity and flexibility for various applications.

With a noise rating of 57 dBA (less noisy than a refrigerator), the inverter generator features a manual recoil starter system.

The KS 2000iS CO's fuel tank holds 1.3 gallon, ensuring uninterrupted operation for around 5 hours at 50% load with a full tank (fuel consumption approximately 0.26 GPH).

The KS 2000iS CO produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel is equipped with the following 2 AC outlets:

Duplex 120V 20A (5-20R)

Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Portability

As the Konner & Sohnen KS 2000iS CO is an inverter generator, its encased design (L19.7 x W11.2 x H18.1 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.

The KS 2000iS CO's weight, at just 41.8 lbs, makes it an ideal choice for those seeking a lightweight and portable generator. It's easy for one person to move around, ensuring power availability on the move. With its handle (molded in the case), carrying it becomes a breeze, adding to its convenience.

Features

The KS 2000iS CO's control panel

Integrated into the control center of the KS 2000iS CO are a convenient meter, showing voltage, frequency, and lifetime hours metrics, facilitating the monitoring of its status and activity.

In addition to this info, when the generator is ready, the oil level is too low and the generator is overloaded, you will be informed by the featured light indicators.

Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

It also includes a carbon monoxide sensor. This sensor 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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Konner & Sohnen KS 2000iS CO also comes with some accessories: funnel and tool kit are included.

The Konner & Sohnen KS 2000iS CO versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Konner & Sohnen KS 2000iS CO compare to inverter generators of similar power (between 1500 and 2500 W).

• When it comes to weight, the Konner & Sohnen KS 2000iS CO tips the scales at just 41.8 pounds, making it one of the lighter inverter generators in the 1500 to 2500 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM2000i, standing at just 34.2 lbs.
• As this inverter generator can emit noise as low as 57 dBA, it finds itself in the average expected noise for this kind of power. If you wish to prioritize minimal noise, the Honda EU2200i stands out as one of the quietest options among generators of similar power, with a rating of 48 dBA.
• Concerning its runtime, the KS 2000iS CO provides around 5 hours at a 50% load, indicating that it falls on the lower side compared to other generators of its type and power range. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Westinghouse iGen2200, with around 10 hours.
• While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. In terms of fuel efficiency within its wattage range, this inverter generator falls short: it consumes approximately 0.26 GPH at a 50% load. If minimizing fuel usage is one of your key priorities, the Westinghouse iGen2200 is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.11 gallons per hour.
