Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Dometic Brisk II B57915.71X (13,500 BTU) (8,856W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Dometic Brisk II B57915.71X (13,500 BTU) | 1,788W | 8,856W | Safe | ~2.4h | OEM Manual |
Show expert analysisTechnical: This 13,500 BTU rooftop unit is a high continuous compressor load. Using OEM current and locked-rotor values, modeled running demand is 1788W with OEM-derived startup demand at 8856W. Field note: For RV battery systems, this is a realistic upper-bound 13.5k BTU profile to test first before selecting any smaller rooftop AC model. Can a portable power station run a 13,500 BTU RV rooftop AC? Only if it can cover this profile at 120V: 1788W running and 8856W startup (or equivalent soft-start handling). In practice, startup headroom is usually the limiting factor. | |||||
| Coleman-Mach 8 Plus (13,500 BTU) | 1,633W | 4,899W | Safe | ~2.6h | NEC Standard |
Show expert analysisTechnical: Coleman-Mach 8 Plus sits in the same rooftop AC class but with slightly lower modeled continuous draw than the Dometic worst case in this set. Field note: Treat this as a serious RV cooling load, not a light camping appliance. Prioritize surge headroom before runtime calculations. Can a portable power station run a 13,500 BTU RV rooftop AC? Only if it can cover this profile at 120V: 1788W running and 8856W startup (or equivalent soft-start handling). In practice, startup headroom is usually the limiting factor. | |||||
| Airxcel Mach 10 45203-8*6 (13,500 BTU) | 1,450W | 7,245W | Safe | ~3.0h | OEM Manual |
Show expert analysisTechnical: Mach 10 provides an OEM direct running watt value in the 13.5k BTU class, making it a useful mid-range benchmark for RV rooftop cooling. Field note: When comparing stations, check both sustained inverter output and startup tolerance. One without the other is not sufficient for rooftop AC duty. Can a portable power station run a 13,500 BTU RV rooftop AC? Only if it can cover this profile at 120V: 1788W running and 8856W startup (or equivalent soft-start handling).

Before You Buy: Connection Check
RV connection
RVs often use a 30A plug. If the station only has standard outlets, you may need an adapter and will be limited to standard outlet power (~1800W).

Generator Insights
With 24,000W surge capacity, this system can handle typical compressor startup events found in central air conditioners, well pumps, and refrigeration equipment. The 12,000W continuous rating supports sustained high-load operation across multiple circuits. At 6,144Wh usable capacity, runtime depends on connected load, but this configuration can support whole-home essentials during extended outages.
This unit uses LFP chemistry, a formulation widely recognized for thermal stability in residential backup applications. The manufacturer provides operational guidelines in their documentation, and users should follow all installation and grounding instructions.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
RV rooftop AC is a compressor-dominant 120V load class where both continuous draw and startup behavior matter. This parent profile uses the most demanding variant in the set to prevent under-sizing recommendations.
Expected Behavior
Estimated runtime: ~2.4h. In real RV use, a rooftop AC can run for hours once started, but startup and hot-weather margin are the key electrical constraints. Soft-start capable setups widen compatibility.
Field Note
For boondocking decisions, evaluate surge headroom first, then battery runtime for the planned cooling window.
Frequently Asked Questions
Can the EcoFlow Delta Pro Ultra X power a RV Rooftop AC?
Yes. The EcoFlow Delta Pro Ultra X provides 12000W running / 24000W surge. The RV Rooftop AC (13,500 BTU) needs 2235W / 11070W (including 25% buffer). That leaves 9765W of running headroom and 12930W of surge margin.
How long will the Delta Pro Ultra X run a RV Rooftop AC?
Approximately 2.4 hours, based on the RV Rooftop AC (13,500 BTU)'s 1788W draw and the Delta Pro Ultra X's 6144Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 2480W allocated to the RV Rooftop AC (13,500 BTU), the Delta Pro Ultra X still has ~5332W of margin. These devices could run simultaneously:
