300w pump running on an inverter

[DarrenD]

Could I run my RO pump of an inverter? The pump is 307w. Ideally I’d like to run it of the cigarette plug but the biggest inverter I can find for that is 300w ? Thanks

Short answer = no.

Your r/o pump (booster pump?) will draw an initial surge of 2 to 3 times the 307w. So you will need a much bigger inverter to compensate for that.

Then you need to read and understand this.
