| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Carrier Infinity 59MN7A 080 (80,000 BTU) | 886W | 1,461W | Safe | ~1.6h | OEM Manual |
Show expert analysisTechnical: **Running load:** 886W (115V ร 7.7A FLA, OEM rated). **Surge:** 1,461W (115V ร 12.7A start amps, OEM rated). **Voltage:** 120V AC. The ECM variable speed blower ramps up electronically with a controlled startup โ the 1,461W surge is brief and predictable. Field note: The Carrier Infinity is the most generator-friendly furnace blower in this comparison. The ECM variable speed motor keeps both running and surge watts low. Most power stations above 1,500W can handle this unit without issue. Can I run a Carrier Infinity furnace on a portable power station during a winter outage? Only if your power source can supply at least 886W continuous and 1,461W surge at 120V. The ECM variable speed blower has a controlled startup that most mid-size power stations can handle. | |||||
| Trane S8X1 B080 (80,000 BTU) | 1,058W | 1,587W | Safe | ~1.4h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1,058W (115V ร 9.2A FLA, OEM rated). **Surge:** 1,587W estimated (1.5ร for ECM constant torque motor โ OEM start amps not published). **Voltage:** 120V AC. The 3/4 HP constant torque ECM blower draws more than the Carrier variable speed but still benefits from electronic startup control. Field note: The Trane S8X1 is a mid-range 80% AFUE furnace common in existing homes. The 9-speed ECM blower is more efficient than old PSC motors but draws more than premium variable speed models. A 2,000W power station provides adequate headroom. Can I keep my Trane furnace running on battery backup during a winter storm? Only if your power source can supply at least 1,058W continuous and 1,587W surge at 120V. The ECM blower has a moderate startup demand that most 2,000W+ power stations can handle. | |||||
| Goodman GMH8 0805B (80,000 BTU) | 810W | 2,430W | Safe | ~1.8h | NEC Standard |
Show expert analysisTechnical: **Running load:** 810W (derived from OEM Min Circuit Ampacity 8.8A de-rated by NEC 1.25ร factor). **Surge:** 2,430W (3ร running per NEC for PSC induction motor โ OEM LRA not published). **Voltage:** 120V AC. The 4-speed PSC motor creates a hard mechanical inrush on every startup โ three times the running load. Field note: The Goodman GMH8 represents millions of builder-grade furnaces installed across the US. The PSC motor surge is the critical factor โ running watts are actually lower than ECM models, but the 2,430W startup spike will trip any power station under 2,500W. This is the #1 reason furnace blowers fail on small generators. Why does my power station shut off when the Goodman furnace blower starts? Because the PSC blower motor creates a 2,430W startup surge โ 3ร its 810W running draw. Most power stations under 2,500W surge capacity will trip on this inrush. You need a station rated for at least 2,430W surge to handle it reliably. | |||||

The 4800 W surge can support typical startup loads for refrigerators, well pumps, and air compressor motors that require momentary inrush current. The 2048 Wh capacity provides extended runtime for moderate continuous loads. This configuration can handle brief motor starts while sustaining steady power delivery for home backup scenarios.
This unit uses LFP chemistry, which offers a different thermal profile than older lithium chemistries. The manufacturer provides operational guidelines in their documentation.

Yes. The EcoFlow DELTA 2 Max provides 2400W running / 4800W surge. The Gas Furnace Fan (Blower) needs 1217W / 2795W (including 15% buffer). That leaves 1183W of running headroom and 2005W of surge margin.
Approximately 1.4 hours, based on the Gas Furnace Fan (Blower)'s 1058W draw and the DELTA 2 Max's 2048Wh capacity (70% usable after real-world losses).
With 855W allocated to the Gas Furnace Fan (Blower), the DELTA 2 Max still has ~7W of margin. These devices could run simultaneously:
Power Tip: To get the most out of your DELTA 2 Max, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.
