WEN 56203i Portable Inverter Power Generator Features and Specifications

WEN 56203i is powered by a single-cylinder, 4-stroke, air-cooled, 79cc gas-powered engine, ensuring 1700 Running Watts and 2000 Starting Watts.

The engine features a manual-only start system - but, the engine is relatively small and when maintained properly, the engine is easy to start.

The fuel tank features a capacity of 1.06 gallons (4 liters) which is enough for 7 hours of constant operation at 50% load (850W) or 10.8 hours @25% load (425W).

By default, the engine operates at 4800 RPM, but WEN 56203i features the so-called Eco Mode which allows the engine to operate at different speeds, depending on the load.

Note: In order to provide more than 1000W, the engine must run at 4800 RPM - if You plan to power loads of 1000+ watts, keep the Eco Mode off.

WEN 56203i is powered by gasoline (gas) - it is recommended to use fresh fuel (under one month old) with at most 10% ethanol.

The unit is rather simple to use and maintain, but when it arrives, before the very first use, be sure to read the manual/Owner's Guide, in order to get accustomed to your new power generator. Also, don't forget to add fuel and oil ...

WEN 56203i weighs only 39 pounds (~17.7 kg) dry (no fuel) and thanks to the built-in handle, it can be carried to shorter distances - just be sure not to underestimate ~40 pounds load...

Also, the unit is rather compact and features physical dimensions of 17.3 x 11.5 x 17.7 inches (~44 x 29.2 x 45 cm).

WEN 56203i comes with a fully enclosed body and an advanced muffler, ensuring very low noise levels - around 51 dB @25%, making it one of the quietest generators on the market in the 2000W power generators class.

WEN 56203i power generator is an inverter generator and it features very low Total Harmonic Distortions - only 0.3% without the load and 1.2% THD level when the unit is under 100% load, making it suitable for powering sensitive devices and appliances directly.

WEN 56203i power generator comes with several very interesting features, including Eco Mode, Fuel Shut Off, Overload Warning, Low Oil warning and automatic engine shut off, Parallel Connection Ready, etc.

However, WEN 56203i doesn't feature a Carbon Monoxide (CO) sensor - this sensor is usually found on stronger power generators, but it would be nice to have one.

Note: regardless if the power generator has a Carbon Monoxide sensor, power generators should always be operated outdoors!

The list of receptacles includes AC 120V 2x NEMA 5-20R (~14 Amps max.), 12V 8.3A DC, and two USB 5V charging ports (1.0A and 2.1A).

If that is not enough, WEN offers several Parallel Connection Kits suitable for use with WEN 56203i, including:
