Can The Flex Power Portable Generator 3,300 Watts Run My GE Air Conditioner In My RV ?  

Published 06/17/2026

Question:

Can the Flex Power 3300-watt inverter generator run my RV air conditioner, or do I need something bigger? I have a single GE 13,500 low profile rooftop A/C on my travel trailer.

Hi Angela! Yes, the Flex Power 3,300-Watt Portable Inverter Generator # FP54FR would work well with the GE Appliances HE Low-Profile RV AC w/ Heat Pump # GE86RR based on that A/C’s power draw.

That GE low-profile A/C pulls about 10 to 12 amps during normal operation, which works out to roughly 1,150 to 1,380 running watts on 115V power. Its startup surge is about 20 amps, which converts to about 2,300 starting watts. Since the # FP54FR is rated for 3,300 starting watts and 2,700 running watts, it has enough capacity for that A/C by itself and should still leave some room for smaller loads.

I would still avoid running other high-draw appliances at the same time, like a microwave, coffee maker, toaster, or hair dryer, since those can add a lot of wattage quickly. But for running that GE 13,500 Btu low-profile A/C, Angela, the # FP54FR is the Flex Power model I’d go with. Are you planning to use it mostly for boondocking, or as backup power at home too?
