All AL-KO units run on unleaded gasoline. The 2000i is an inverter machine that is suitable for camping, traveling and boating and as a power source for electrical devices (TV, computer, refrigerator, etc.). Easy to carry and fit from one space to another. A gasoline-powered unit is a handy helper for, for example, a summer cottage. The motor is protected by an overcurrent protection and it also has an oil monitor, which turns off the device when the oil level drops to too low a level. The machine is equipped with an ESC switch ((Engine Smart Control), whereby the control device controls the engine speed according to the power of the electrical devices connected to it. The result is lower fuel consumption and a lower noise level. When the ESC switch is switched to the "OFF" position, the engine runs at the nominal speed (5000 min-1) regardless of whether electrical equipment is connected to it or not.
