asked in category: General Last Updated: 27th June, 2020# What size generator do I need for air compressor?

**need**to figure 1800 to 2000 watts for the

**air compressor needs**on start up. I

**would**recommend a 2500 watt

**generator**.

Simply so, will a 2000 watt generator run an air compressor?

A **2000 watt** handle the load of a 15000 BTU RV **air** conditioner with a higher starting **wattage** capacity **could** let you **run** a 10,000 BTU window **air** conditioner during a summer blackout. The typical such unit has 2200 starting **watts** but only needs 1500 **watts** of continuous **power**.

Also, how many watts does a compressor need? Heavy-duty compressors operate on 220-volt current and require special wiring and outlets. A 110-volt compressor drawing 15 amps uses **1,650 watts** (110 volts x 15 amps), while a 220-volt compressor drawing 15 amps consumes **3,300 watts** (220 volts x 15 amps).

Then, what size generator do I need to run a 2hp compressor?

A 7200 watt **generator** is required to **run** this **compressor**. Example: A circular saw runs a universal motor at 12.5 amps. 120 volts x 12.5 amps = 1500 watts. The starting watts is 1500 x 3 = 4500 watts.

What size generator do I need for my house chart?

Homeowners can often power most **household** appliances using between 3000 and 6500 watts. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your **needs**. If you have a larger furnace and/or a well pump, you will likely **need** a 5000 to 6500 watt **generator**.
