Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Midea MAP12S1TBL (12,000 BTU / 10,000 SACC) (4,071W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Whynter ARC-14S (14,000 BTU Dual-Hose) | 1,250W | 3,750W | Safe | ~3.4h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1250W from OEM maximum power input rating. **Startup surge:** 3750W estimated at 3x for non-inverter R-410A rotary compressor. **Voltage:** 120V AC required. Cross-check: 115V × 10.8A = 1242W confirms rated input. Field note: Dual-hose portables cool more efficiently but draw the same electrical load as single-hose units. The ARC-14S is the lowest-draw variant in this set at 1250W, making it the most power-station-friendly option. Is the Whynter ARC-14S easier on a power station than other portable ACs? At 1250W continuous it draws less than many 12,000 BTU single-hose units, but still requires at least 3750W surge capacity at 120V for compressor startup. | |||||
| LG LP1217GSR (12,000 BTU) | 1,350W | 4,050W | Safe | ~3.2h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1350W from OEM spec sheet. **Startup surge:** 4050W estimated at 3x for non-inverter rotary compressor with R410A refrigerant. **Voltage:** 120V AC required. Cross-check: 115V × 12.0A = 1380W, consistent with OEM wattage. Field note: At 1350W this is the second-highest draw in the set. Verify your power station sustains this load without thermal throttling over multi-hour sessions. Why does this LG draw more watts than other 12,000 BTU portables? Wattage varies by compressor efficiency and design generation. The LP1217GSR uses a 2017-era rotary compressor rated at 1350W max input. Newer models with higher CEER ratings draw less for similar cooling output. | |||||
| Midea MAP12S1TBL (12,000 BTU / 10,000 SACC) | 1,357W | 4,071W | Safe | ~3.2h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1357W derived from OEM nameplate amps (115V × 11.8A). **Startup surge:** 4071W estimated at 3x compressor inrush. **Voltage:** 120V AC required. CEER 14.7 and SACC 10,000 BTU indicate above-average seasonal efficiency for the 12,000 BTU class. Field note: R32 refrigerant is mildly flammable (A2L safety class). For power station sizing, use the 1357W max input rating, not the CEER-derived seasonal average of approximately 680W. Why is the rated wattage so much higher than the CEER efficiency suggests? CEER measures average seasonal efficiency including standby and cycling. The 1357W figure is the maximum draw when the compressor is actively running. Always size your power station for the maximum input, not the seasonal average. | |||||

Before You Buy: Connection Check
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
With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

Spec-Based • No GuaranteesTechnical Breakdown
Running range: 1250W to 1357W across common portable AC designs. Startup range: 3750W to 4071W with standard non-inverter compressors. Voltage: 120V AC. All variants use on/off rotary compressors with 3x estimated startup inrush.
Expected Behavior
Estimated runtime: ~3.2h. Typical usage is 4 hours daily for supplemental or backup cooling. Daily energy consumption ranges from 5000 to 5428Wh depending on the model. Compressor cycling creates repeated surge events throughout operation.
Field Note
Portable ACs are among the hardest 120V loads for power stations due to sustained high draw plus compressor surge. Verify both continuous and peak ratings before connecting.
