How many watts does a 13,500 BTU RV air conditioner use — and what can run it?
A 13,500 BTU RV rooftop AC (Coleman-Mach 10): 1,625 W running in desert heat, 7,560 W locked-rotor start. Which power stations and generators can start it.
Representative model: Coleman-Mach 10, 452X3*8XX. Cooling full-load amps 13.2–13.6 A (compressor 11.0 A + fan 2.2–2.6 A) at A.R.I. standard condition.
The representative model is the Coleman-Mach 10 (452X3*8XX) rooftop unit from Airxcel. Its data sheet gives two running figures for cooling: 1,350 W at the A.R.I. standard condition (95 °F outdoor) and 1,625 W at the desert condition (120 °F outdoor). The site uses 1,625 W; the sheet, while saying Airxcel does not size generators itself, lists the desert-test figure as the one to account for when sizing one. The starting figure is the compressor's locked-rotor current, 63.0 A, times 120 V: 7,560 W.
What changes the draw
Airxcel's two figures show that outdoor heat raises the running draw. Sun on the roof, the thermostat setting and how well the RV holds its cool decide how often the compressor cycles. No daily average is published, so the tables use 1,625 W throughout; at the page's 8 hours a day that is 13,000 Wh.
Why the starting draw decides everything
Locked-rotor current is what the compressor draws before it turns — the upper limit of a start, which lasts a fraction of a second. Generic charts are far lower: the Champion chart lists 2,800–3,500 W starting for a 13,500 BTU RV unit. Using the maker's figure, though, almost every power station on this site fails, and so do generators below 7,560 W starting (fit rule). Stations whose maker publishes no peak figure are marked "Unclear": the start cannot be checked.
Reading the tables
Runtime assumes the compressor never cycles off. Example: the EcoFlow DELTA Pro 3 record has no maker factor, so the default 0.85 applies: 4,096 Wh × 0.85 ÷ 1,625 W = 2.1 hours.
Power stations that can run it
Pass = continuous output ≥ 1625 W and peak output ≥ 7560 W. Runtime = capacity × maker's factor ÷ 1625 W, nothing else plugged in. Method.
