Champion 73536i 2000-Watt Stackable Generator Features and Specifications

Champion 73536i is powered by an 80 cc gasoline engine and is rated at 1700 running watts and 2000 starting watts with very low Total Harmonic Distortion (THD) of less than 3%.

Physical dimensions of the unit are (L x W x H) 19.3 x 13.2 x 16.3 inches (~49 x 33.5 x 41.5 cm) and it weighs 48.5 pounds (~22 kg).

Champion 73536i features a fuel tank with a capacity of 3.8 liters (1 gall) which is enough for 9.5 hours @25% of nominal load (~425 watts). Champion 73536i features the so-called Economy Control Switch which allows the engine to run at the optimum speed considering the load, saving fuel, oil, and prolonging the maintenance interval.

Engine start is manual using a recoil mechanism. The oil tank capacity is 0.4 liters - unit features Oil Warning Light on the Control Panel and when the light is turned On, the engine will not run.

Champion 73536i 2000-watt Stackable Power Generator is a rather quiet unit, with nominal noise levels of 53 dBA from 23 feet (~7 m) of distance.

Controls of the unit are rather simple - nonetheless, when the Champion 73536i arrives, be sure to thoroughly read the Owner's Guide, especially the maintenance procedures.

Overload Indicator Light is turned OFF during normal operation - when ON, no power is present on the receptacles.

Output Light is ON during normal operation, but when it is turned OFF, no power is present on the receptacles.

Champion 73536i Power Generator includes Duplex 120V 20 Amps AC (NEMA 5-20R) receptacles and 12V 8 Amps DC outlet.

The 12V 8A DC outlet is intended for charging automotive (lead-acid) type of batteries and the unit comes with a suitable charging cable for such batteries.

In order to charge larger batteries, it is recommended to connect such battery chargers directly into the AC port and to use Economy Switch to let the unit optimize the engine RPM according to the load.

For example, 12V 25 Amps battery charger may be powered by Champion 73536i for up to 10 hours (or even slightly more), easily recharging the 12V 200Ah battery with the single fuel tank.

Champion 73536i doesn't feature USB charging ports, but if required, USB chargers may be plugged directly into the 120V AC ports.

Champion 73536i 2000-Watt Stackable Inverter Generator is designed to be connected in parallel with the compatible inverter generator.

Thanks to the design, such arrangement requires almost no extra space.

In order to connect two Champion 73536i generators in parallel, an additional Champion Model 73500i Cable Kit is required.

Champion Model 73500i Cable Kit features 120V 30A RV (TT-30R) and 120V 30A (L5-30R) locking outlets and allows the pair of Champion 735636i power generators to provide 3000 watts of running power.

Long Story Short: Champion 73536i Stackable Inverter Generator is perhaps a somewhat older model, but it is still a very popular model that offers reliable power and is very liked by its owners.

If more than its 1700/2000 running/starting watts are required, a pair of Champion 73536i generators may easily be connected in parallel - a very popular solution of many RV owners.
