Description
Zoom on the Konner & Sohnen KS 2000iHS CO
In a nutshell, the Konner & Sohnen KS 2000iHS CO is a quiet, compact and lightweight portable inverter generator mostly geared towards:
- Camping and tailgating hobbyists looking for a portable power source
- Handcrafting enthusiasts who wish to work on-the-go
In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
Power & Run Time
Featuring dual-fuel technology, the Konner & Sohnen KS 2000iHS CO provides 120V, as well as versatility and power. Running on gasoline, it delivers a running wattage of 1,800W and a peak wattage of 2,000W. Alternatively, when fueled by propane, it offers 1,620 running watts and 1,800 peak watts. Moreover, since it is parallel capable (parallel kit not included), its power may be doubled if linked to a second compatible unit.
With a noise rating of 57 dBA (less noisy than a refrigerator), the inverter generator's ignition is facilitated by a simple traditional pull-start mechanism.
Concerning its running time, the KS 2000iHS CO, featuring a 1.3 gallon fuel tank, can continuously run for around 5 hours at 50% load with a full gasoline tank (consuming fuel at approximately 0.26 gallons per hour). Alternatively, when utilizing propane, it offers around 13.5 hours (estimation based on a 20 lbs tank - propane consumption around 0.35 GPH) of runtime.
With a <3% Total Harmonic Distortion (THD), the KS 2000iHS CO delivers a clean sine wave, essential for safeguarding your delicate electronics when plugged into its AC outlets.
Outlets
The control panel features the following 2 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) enabling convenient charging of devices like mobile phones and tablets.
Portability
The Konner & Sohnen KS 2000iHS CO's characteristic encased inverter generator design (L19.7 x W11.2 x H18.1 in) provides an aesthetic advantage and contributes to quieter operation compared to any ordinary, open frame product. This modern design aims to provide an ideal power solution to recreational users.
At just 41.8 lbs, the KS 2000iHS CO is notably lightweight, making it an excellent choice for portable power. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. Its handle (molded in the case) allows you to carry it easily, further enhancing its convenience.
Features
The KS 2000iHS CO's control panel
Integrated into the control center of the KS 2000iHS CO are a convenient meter showing you voltage, frequency and lifetime hours, facilitating the monitoring of its status and activity.
In addition to this info, light indicators on the device will notify you if the generator is ready, the oil level is too low and the generator is overloaded.
The built-in fuel gauge of the inverter generator ensures simple and quick gas level assessments.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
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.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Konner & Sohnen KS 2000iHS CO, the following accessories are also included: funnel, propane hose and tool kit.

The Konner & Sohnen KS 2000iHS 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 2000iHS CO compare to inverter generators of similar power (between 1500 and 2500 W).
- When it comes to weight, the Konner & Sohnen KS 2000iHS 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. If weight is a key factor for your needs, the Genmax GM2000i is noteworthy for being one of the top contenders in this power range, with a dry weight of 34.2 pounds.
- At 57 dBA, this inverter generator's noise rating is in line with the expected average for devices within its type and power category. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
- As far as autonomy is concerned, providing around 5 hours of runtime with a full tank at a 50% load, the KS 2000iHS CO falls into the low end in comparison with other inverters of a comparable power output. For those prioritizing autonomy, the Westinghouse iGen2200 could be considered, as it offers one of the longest run times among generators with similar power output, reaching 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. In fact, this inverter generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 50% load is around 0.26 GPH. 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.
Price comparison
As you can see from these interactive charts, when compared to other 1500-2500W dual fuel inverter generators, the Konner & Sohnen KS 2000iHS CO is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

- Dual fuel
- CO sensor
- USB-C port
- Parallel capable
- Inverter
- Lightweight (41.8 lbs)
- Acceptable noise (57 dBA)
- Relatively low run time
