Könner & Söhnen 2000W Portable Inverter Generator | Super Quiet 57 dB, Pure Sine Wave | KS 2000iS CO

Könner & Söhnen 2000W Portable Inverter Generator | Super Quiet 57 dB, Pure Sine Wave | KS 2000iS CO

Q: How long does it run on a tank?

5 hours at 50% load on its 1.3-gallon tank. Eco Mode extends that further at lighter loads.

Q: Is it safe for laptops and phones?

Yes. The pure sine wave inverter delivers clean, wall-quality power safe for sensitive electronics.

Q: Can I connect two of them together?

Yes - it&#39;s parallel-ready. Add the KS Parallel Unit (sold separately) to combine two KS 2000iS CO units for more power.

Q: Can this power my house during an outage?

It&#39;s built for light backup - a fridge, lights, a router, and device charging - not a whole house. For larger loads or a full home-backup setup, look at the KS 6000iES CO or KS 6000iEHS CO.

Q: Does it have an electric start?

No - this model uses easy-go recoil (pull-cord) start.

Q: What's in the box?

The generator, owner&#39;s manual, spark plug wrench, PH2 screwdriver, and an oil funnel. (No oil or gas included - add 10W-30 or 10W-40 before first start; use 87-octane or higher, up to 10% ethanol is fine.)

Specification

Voltage, V:	120
Starting watts, W:	2000
Running watts, W:	1800
Engine start:	recoil
Outlets:	2 x 20A

Benefits

CLEAN POWER: 2,000 starting / 1,800 running watts, delivered as a pure sine wave (<3% THD) - safe for laptops, phones, TVs, and sensitive equipment like a CPAP, not just power tools.
GRAB IT AND GO: At 41.8 lbs with a compact 21.8" x 13.2" x 21.2" footprint, it's genuinely one-person portable - fits in a trunk, a truck bed, or an RV bay without a second thought.
QUIET ENOUGH FOR THE CAMPSITE: 57 dBA at 23 ft - well within "normal conversation" range, and quiet enough that it won't be the loudest thing at the campground.
BUILT-IN CO SAFETY SHUTOFF: Automatic carbon-monoxide sensor shuts the engine down if CO climbs to a dangerous level, alongside overload protection and a low-oil sensor. (Always run it outdoors - see safety note.)
PAIR TWO FOR MORE POWER: Parallel-ready out of the box - connect a second KS 2000iS CO (with the optional Parallel Unit bought separately) when you need more than 1,800 running watts, then break them apart for solo trips.

Features

The KS 2000iS CO is the generator you throw in the truck bed without thinking twice. It delivers pure sine wave power ( (<3% THD)) clean enough for a laptop, a phone charger, a mini-fridge, or a CPAP, backed by a CopperCore copper-wound alternator and a built-in CO safety shutoff - all in a compact, 41.8 lb frame you can carry with one hand. It won't run your whole house, but for camping trips, tailgates, job sites, and keeping the essentials alive during a short outage, it's built to start every time and run for hours on a single small tank.

Parallel Ready

Connect two KS 2000iS CO units through the optional Parallel Unit and combine their output for bigger jobs - then split them apart when you only need one. Works across the whole parallel-ready K&S inverter line (KS 2000iS CO, KS 2000iHS CO, KS 4000iEHS CO), so it's an upgrade path.

Ergonomic Control Panel

Everything in one place: a multifunction LED display (hours, frequency, voltage), overload and short-circuit protection, a low-oil sensor, a reset button, the parallel-connection port, 2 USB outputs (5V/1A and 5V/2.1A), and a grounded 120V outlet.

CopperCore Brushless Alternator

A brushless permanent-magnet alternator wound with 100% copper, not the cheaper copper-clad aluminum found in budget units. Sealed in a durable housing and built to take full load without wearing down - the same alternator design used across all K&S inverter line.

Eco Mode

A dedicated fuel-economy switch drops engine speed to match the load. At light loads, that cuts fuel use by up to 50% and stretches a small 1.3-gallon tank considerably further - useful when you're miles from the next gas station.

Clean Power

A microprocessor-controlled inverter holds output to a stable 120V/60Hz sine wave - the same power quality that comes out of a wall outlet. That's what makes it safe for laptops, phones, and other sensitive electronics that a rough-power generator can damage.

Soundproof Housing

A purpose-built soundproof housing keeps noise down to 57 dBA - quiet enough to sit next to at a campsite, on a job, or outside the window during a short outage.

Serialized Engine

Every engine carries a factory serial number, which helps confirm you're getting a genuine K&S unit and makes parts lookup straightforward if you ever need service.

*** Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 87 or higher. t's acceptable to use gasoline with 10% bio-ethanol.

A compra correu muito bem com a transportadora a efectuar a entrega no período previsto. O equipamento vinha bem embalado. Já efectuei o teste de funcionamento (cerca de uma hora em carga media) e funciona sem qualquer problema. Tudo conforme as especificações, fotos, etc, disponíveis no site.

alles Top

Der Inverter Stromerzeuger ist ein gutes Gerät. Nur wehe wenn man noch Luftfilter Oder Zündkerzen braucht. In Bereich der Ersatzteile müsste man noch einmal aufholen.

Schnell und gute Erledigung

Voldoet aan mijn verwachtingen, wel beetje jammer dat er geen Nederlandse beschrijving bij zit.
