Runtime evidence · sourced load
An RV air conditioner draws 1,260 W while running. 1 station covers that running draw, but no source publishes a startup surge for the RV rooftop air conditioner (Truma Aventa eco, 13,500 BTU) — so no station here can be confirmed to start it.

These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.

Replace the representative load with a typical-day meter reading. Add the running and startup watts from your own label or meter to update the inverter checks. These entries only change this page view.

Blank uses the sourced default. Enter nameplate watts or a meter reading while the compressor or pump is running.
Leave blank to use a sourced figure when available. Enter real startup watts only from an OEM source or an inrush meter; an LRA amp rating is not a watt value.

Runtime ladder uses the same comparison assumptions as the table above. Station-specific fit below uses each model's capacity and inverter data.
0 of 80 stations pass the capacity, running, and startup checks for 8 hr using published station specs; appliance startup remains unverified.
Startup remains unverified. 1 station cover the entered energy and running watts, but none is counted as a confirmed start.

Station checks use data on linked model profiles. Temperature, compressor cycling, wiring, inverter behavior, and actual starting current can change results.
02 · Reading the numbers
A 13,500 BTU rooftop unit draws about 1,260 W once running, which sounds manageable and is not the number that matters. Rooftop air conditioners are hard-start loads: the compressor demands a large multiple of that for the instant it breaks away, and the manufacturer publishes a starting current rather than a starting wattage.
Matching the inverter to the running watts. "My station does 2,000 W and the AC needs 1,260 W" is the single most common miscalculation in RV power, and it is why soft-start kits are one of the best-selling RV accessories in existence. The other mistake is planning to run it overnight: even where a station can start the unit, rooftop air conditioning is a several-kilowatt-hour-per-night load.
We do not publish a startup figure for this unit because Truma does not publish one in watts, and we will not convert a current rating into a wattage without knowing the power factor at start. That is why this page reports no station as confirmed to start it — not because none can, but because we cannot prove which.
