what will a 3000 watt generator run

A 3000-watt generator can be used for a variety of purposes and can power many devices, but can it power your desired equipment? If you are going to buy a new one, or already own one and want to know what it can run. 

A 3000-watt generator can power a Refrigerator, 1HP sump pump, 1-ton air conditioner, iron, washing machine, microwave oven, hair dryer, coffee maker, computer, TV, and many others. It can be used for camping, DIY projects, mobile detailing, mobile DJ and more. 

Further next in this article, we listed all possible single devices along with their starting and running watts, we also listed those devices which you should not use with a 3000-watt generator. 

We also make different combinations of devices with wattage tables, which you can use together with a 3000-watt generator. We made all calculations based on starting watts of the generator.

Before going further deep some preliminaries are necessary for better understating, what we are discussing.

Either you should power single devices or a combination of devices but their combined power in terms of starting watts should not surpass 2950 watts. 

Starting Watts 

A device needs extra power for starting, which is referred to as starting watts.

Running Watts

For the device to run smoothly, it requires a relatively stable amount of electricity (called running watts).

Combinations Of Devices that can be operated together

Here we listed some basic possible combinations of devices that can be operated on the 3000-watt generator, and similarly you can also make your own combination by adding watts of desired appliances both in terms of the surge and running.

1st Combination

The first basic combination of appliances is a Refrigerator, 4xfans, 5xlights, and laptop charging that needs approximately 2900W as surge watts, and 1400W as running.
