What can you Run on a 2000-Watt Generator?

The wattage rating of your generator dictates how much of a load the generator can carry per single time. The wattage on your devices, on the other hand, determines how much power the appliance will draw from the generator per unit time.

A 2000-watt generator can run a cook with a 650 watt microwave of not more than 1000 watts and a few lights all connected. It can run a single mid-sized fridge of not more than 1200.It can also run a couple of other small devices all connected.

It is important to understand that for the generator to power up a device, the number of Watts supplied must at least match the power needed by the appliance. It must, first of all, match the starting wattage of the appliance followed by the running wattage.

As their names suggest, the starting wattage is the power needed to start the device while the running wattage is the power needed to keep the device running. In most cases, the starting wattage is either more or equal to the running wattage.
