Description
Zoom on the Konner & Sohnen KS 6000iES CO
To sum up, the Konner & Sohnen KS 6000iES CO is a compact portable inverter generator tailored for:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners in need of an emergency backup power for their essentials
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The Konner & Sohnen KS 6000iES CO's design includes a gasoline-fueled 223 cc (9 hp) OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5,000W and also a peak wattage of 5,500W. Moreover, the parallel capability (parallel kit not included) enables power output to increase when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.
With a noise rating of 64 dBA (just slightly more noisy than background music), the inverter generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).
The KS 6000iES CO boasts a fuel tank capable of holding 2.9 gallons, allowing it to run continuously for around 6.8 hours at 50% load (with fuel usage averaging around 0.43 gallons per hour).
Featuring a <3% Total Harmonic Distortion (THD), the KS 6000iES CO delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.
Outlets
The control panel includes the following 3 AC outlets:
Moreover, it boasts 3 DC outlets: there's two 5V USB ports (USB-C) perfect for conveniently charging mobile phones, tablets, and other electronic devices and a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy.
The KS 6000iES CO's twist-lock L14-30R receptacle makes it transfer switch ready, enabling hassle-free connection to your breaker box for powering your home during outages.
Portability
With an inverter generator design, the Konner & Sohnen KS 6000iES CO features a closed construction (L25.2 x W16.7 x H23.6 in), enhancing aesthetics and ensuring reduced noise levels, offering a distinct advantage over standard, open frame generators. This modern design aims to provide an ideal power solution to recreational users.
With a dry weight of 86.9 lbs, the KS 6000iES CO can easily follow you wherever your power needs are. Moreover, its set of 2 wheels and its folding handle facilitate movement of the generator once it's on the ground.
Features
The KS 6000iES CO's control panel
Designed with a digital data center, the control panel of the KS 6000iES CO grants you access to crucial data on the lifetime run hours, power output, voltage, fuel level and frequency, ensuring practical monitoring of its status and activity.
In addition to this info, some light indicators allow you to instantly see if the oil level is too low, the generator is ready and the generator is on overload.
As far as security is concerned, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during 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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Konner & Sohnen KS 6000iES CO also is packed along with the following accessories: funnel and tool kit.

The Konner & Sohnen KS 6000iES 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 6000iES CO compare to inverter generators of similar power (between 4500 and 5500 W).
- As far as its dry weight is concerned, the Konner & Sohnen KS 6000iES CO weighs just 86.9 pounds and thus, it is one of the lightest 4500 to 5500 rated wattage inverter generators.
- The inverter generator can be considered average in its noise for its type and power category, as it is rated at 64 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
- Regarding its runtime, the KS 6000iES CO operates for around 6.8 hours at a 50% load, positioning it at the lower spectrum among comparable inverters. 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 Briggs & Stratton Q6500 QuietPower, with around 10 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. With a fuel consumption rate around 0.43 GPH (gallon per hour) at 50% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If minimizing fuel usage is one of your key priorities, the DuroMax XP7000iHT is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.38 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 4500-5500W inverter generators, the Konner & Sohnen KS 6000iES CO is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
