Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Frigidaire Standard Window AC (FHWC084WB1) (2,010W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Midea U-Shaped Inverter (MAW08V1QWT) | 710W | 1,065W | Safe | ~3.5h | OEM Verified |
Show expert analysisTechnical: **Running load:** 710W (OEM rated cooling watts). **Surge:** ~1,065W (inverter ramp-up, no hard compressor start). **Voltage:** 115V AC, 8.78A AHAM rated. The variable-speed inverter compressor eliminates the traditional startup spike that trips smaller power stations. Power factor ~0.70 (710W real power vs 1,010 VA apparent). Field note: This is the most battery-friendly 8,000 BTU window AC on the market. The inverter eliminates the 3x surge spike that kills small generators. A power station rated 1,000W or above can handle this unit, though running draw at full cooling (710W) uses most of that headroom. Can I run the Midea U-Shaped inverter AC on a portable power station? Yes — the inverter compressor draws up to 710W running with a ~1,065W soft startup, making it compatible with most power stations rated 1,000W or above. No hard compressor surge to worry about. | |||||
| Frigidaire Standard Window AC (FHWC084WB1) | 670W | 2,010W | Safe | ~3.8h | NEC Standard |
Show expert analysisTechnical: **Running load:** 670W (OEM rated). **Surge:** 2,010W at compressor startup (3x NEC standard). **Voltage:** 115V AC. Traditional on/off compressor cycles create hard inrush events every time the thermostat calls for cooling. Field note: This is the worst-case scenario for battery backup. The 2,010W compressor surge will trip any power station under 2,500W rated output. Budget window ACs are the #1 reason portable generators overload during heat waves. Why does my power station shut off when the Frigidaire AC compressor kicks in? The compressor startup surge hits ~2,010W — roughly 3x the 670W running load. Your power station's inverter must handle this peak without tripping. You need at least 2,500W surge capacity. | |||||
| LG Dual Inverter Smart AC (LW8022IVSM) | 516W | 800W | Safe | ~4.9h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 516W (derived from 8,000 BTU at CEER 15.5). **Surge:** ~800W (dual inverter ramp-up). **Voltage:** 115V AC. The dual inverter compressor provides the highest efficiency in this class with the lowest startup demand. Field note: Premium efficiency and the lowest power demand in this class. Like the Midea, the dual inverter eliminates hard surge events. Ideal for smaller battery systems where every watt counts. Can I run the LG Dual Inverter window AC on battery power? Yes — with only ~516W running and ~800W soft startup, this unit works with most power stations rated 1,000W or above. The dual inverter technology avoids the compressor surge that overloads smaller systems. | |||||

Installation warning
These systems are often hardwired to a home panel. To run them from a portable station, you may need a transfer switch installed by an electrician. You cannot just plug it in.

Generator Insights
The 7200W surge capacity can support typical motor-driven appliances during startup, including air compressor motors, well pumps, and refrigeration units that demand brief high-current events. The 3600Wh capacity provides extended runtime for moderate loads, though actual performance depends on connected equipment and environmental conditions. This unit can handle typical whole-home essentials when loads are properly managed.
The Delta Pro uses LFP chemistry, a lithium iron phosphate formulation widely recognized for thermal stability in residential applications. The manufacturer provides operational guidance in their documentation, but users must follow all installation and usage instructions to minimize risk.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 516–710W depending on model (inverter vs. on/off). Surge: 800–2,010W. Voltage: 120V AC required. The technology gap between inverter and traditional compressors creates drastically different power station compatibility — a Midea inverter runs on a 1,000W station while a Frigidaire on/off needs 2,500W+.
Expected Behavior
Estimated runtime: ~3.5h. 8,000 BTU units cool rooms up to 350 sq ft. Inverter models (Midea, LG) draw 300–710W variable with soft ramp-up. Traditional on/off models (Frigidaire) draw 670W constant with 2,010W compressor surges. Daily energy: 3,100–5,360 Wh over 8 hours depending on model and cooling load.
Field Note
Before buying a power station for window AC backup, check if your unit is inverter or on/off — it changes the minimum generator size by 2x. Inverter ACs are the best investment for battery-powered cooling during heat emergencies.
