What Size Generator Do You Need to Run a Electric Pressure Washer (2000 PSI / 13A)?
To safely power a Electric Pressure Washer (2000 PSI / 13A) during a blackout without tripping breakers or damaging the motor, you need a generator rated for at least:
Why Inrush Current (Starting Watts) Matters for Electric Pressure Washer (2000 PSI / 13A)
An electric pressure washer utilizes a universal or induction motor coupled with a high-pressure wobble-plate or axial cam pump. When the trigger is pulled and the motor starts under hydraulic load, it experiences an inrush current surge approximately 2.5 times its normal running amperage to overcome static water pressure and mechanical inertia.
Many portable generators are marketed by their surge wattage rather than their continuous rating. For instance, a "2200W generator" typically provides 1,800 running watts and only delivers 2,200W for a split second. Always ensure your generator satisfies both the continuous and peak surge requirements of your setup.

Recommended Extension Cord Wire Gauge (AWG)
Running an appliance on an undersized (thin) extension cord causes severe voltage drop, overheating the generator and potentially burning out the appliance motor.
| Cord Length | Amps Drawn (13A) | Minimum Wire Gauge | Safety Rating |
|---|---|---|---|
| Up to 25 ft | 13 Amps | 14 AWG | Safe |
| 25 to 50 ft | 13 Amps | 12 AWG (Heavy Duty) | Recommended |
| 50 to 100 ft | 13 Amps | 10 AWG (Extra Heavy Duty) | Essential to prevent voltage drop |
