Model-Specific Results
2 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 | Soft Start | ~1.6h | 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 | ~1.8h | 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 | Tight | ~2.0h | 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
The 8000W surge rating can support typical compressor startup in residential air conditioners, well pumps, and refrigeration equipment. Most single-phase motor loads under 2HP can start on this surge budget. The 4000W continuous capacity can handle simultaneous operation of multiple circuits including HVAC blowers, lighting, and standard appliances during extended outages.
This unit provides 4096Wh of LFP battery capacity with 4000W continuous and 8000W surge output capability. Source: EcoFlow DELTA Pro 3 User Manual v1.1 (AC Output Specifications) (manufacturer documentation). The LFP chemistry offers thermal stability compared to older lithium-ion chemistries, though all battery systems require proper ventilation and adherence to installation guidelines.

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: ~1.6h. 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.
