Hi. 3 full days without power here and no estimate on restoration, and I want to plug in am air mattress pump so we can sleep in the basement where it's about 25 degrees cooler. The specs for the pump are 135 W and 1.2 amp. I see the car outlet says 120W and 10A max. So can I buy a 150 W inverter without blowing a fuse or otherwise damaging the car? Is it some combination of Watts times Amps? 2011 Prius 3 Thanks guys!!
