Sometimes, but not with most models. A typical RV air conditioner needs roughly 1,200 to 2,000 running watts and a much higher surge at startup, so you need a power station with a high AC output and a large battery. Smaller Jackery units cannot do it, and even the larger ones will run an AC for a limited time.
What decides whether it works
Check three numbers, and confirm each against the label on your AC unit and the official Jackery spec page for the model you are considering.
- Running watts: A 13,500 BTU rooftop unit commonly draws around 1,200 to 1,800 W. A 15,000 BTU unit often draws more. The data plate on your unit gives the actual figure.
- Startup surge: The compressor can briefly draw two to three times its running watts. The power station's surge rating must cover it. A soft-start device on the AC can lower this surge, but results vary by unit, so check with the manufacturer of the device.
- Battery capacity (Wh): Runtime is roughly watt-hours divided by the AC's average draw, minus inverter losses. The compressor cycles on and off, so real average draw is often below the label figure, but it depends on temperature, insulation and thermostat setting.
Rough runtime math
This is an illustration, not a test result. A 2,000 Wh battery feeding an AC that averages 1,000 W gives a bit under two hours once losses are counted. A 1,500 W average would give less. Even a 3,000 Wh battery may only cover a few hours of cooling. Overnight use generally calls for expansion batteries or a different approach.
| Situation | Realistic expectation |
|---|---|
| Power station under about 1,500 W AC output | Unlikely to start a rooftop RV AC |
| High-output station, modest battery | May start the AC, but only for short runs |
| High-output station plus expansion batteries | Longer runtime, higher cost and weight |
| Small window or 5,000 to 8,000 BTU unit | Easier to power, with less cooling capacity |

- Pre-cool the RV while on shore power, and park in shade.
- Recharging an AC-sized battery from solar takes a lot of panel capacity, so plan for it.
- Confirm current specs, compatibility and any RV-specific accessories on the official Jackery site before buying.
- If you are wiring the power station into the RV's electrical system, consult a qualified RV technician or electrician.
