The Mantus Scuba Compressor uses a 1.3 kW electric motor, but with the peak current on start of the machine the wattage can be 3 times higher to around 3600 W. Most inverters have a 50% overload capacity, meaning a 2000 W inverter will have only 3000 W overload capacity. To be safe, a 3000W inverter would be the minimum we would recommend.

Gas generators will sometimes have more than 50% overload capacity for startup. For example the Honda 2000W 30amp model can start our compressor.

If you are using an inverter or generator that barely meets these requirements, you may need to start the compressor at 0 PSI. Connect your scuba tank but leave its valve closed so it is sealed from the compressor. Drain remaining air in the compressor. Now when you start your compressor, it will draw much less surge amps to get the motor spinning. Then you can slowly open your scuba tank and fill as normal.
