POWER INVERTER? CONVERTER? ?

My current 400 watt modified wave unit duns electronics okay but will not run Cpap machine or box fan so I am told I need a pure sine wave unit. So what size unit would you suggest to run the above equipment? If I get a larger unit than what I need will it use more power even if I don't reach max capacity? I really am ignorant on this and Youtube video's have not really told me much. Any thoughts?
