Natural Gas / Propane Clothes Dryer (120V Drum & Igniter): Running Watts, 900W LRA Surge, Generator Size & LiFePO4 Battery Runtime
A Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) requires 350 running watts (2.92A at 120V via a NEMA 5-15P plug) and spikes to 900 starting surge watts (2.6× LRA inrush). At a realistic 75% duty cycle (~263 Wh/hr net burn), you need a minimum 900W inverter or generator and at least 4,126 Wh (~323 Ah @ 12.8V) of LiFePO4 battery capacity for a 12-hour blackout. Our top-matched plug-and-play solar generator for a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) is the Bluetti AC200L.

Running Watts, LRA Surge & Field Sizing Guidance
Unlike 240V electric dryers that pull 5,400W, a natural gas or propane dryer plugs into a standard 120V 15A outlet and uses only ~350W to tumble the drum and fire the gas burner (~260 Wh per load).
Waveform Verdict: Pure Sine Wave Mandatory (<3% THD)
Electronic moisture-sensing boards and silicon-carbide hot-surface gas igniters require clean 120V sine wave power.

Frequently Asked Sizing Questions: Natural Gas / Propane Clothes Dryer (120V Drum & Igniter)
How many watts does a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) use to start and run?
A typical Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) draws 350 continuous running watts (2.92A at 120V via a NEMA 5-15P plug) and spikes up to 900 peak startup surge watts (2.6x running load). With a realistic 75% hourly duty cycle, it consumes approximately 263 Wh per hour.
What size solar generator or battery backup will run a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) overnight?
Accounting for 85% AC inverter conversion efficiency and 90% LiFePO4 usable depth-of-discharge (0.765 total factor), running a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) requires 1,376 Wh for 4 hours, 2,751 Wh for 8 hours, 4,126 Wh (~323 Ah @ 12.8V / ~81 Ah @ 51.2V) for 12 hours, and 8,251 Wh for 24 hours. Our top-matched solar generator for this load is the Bluetti AC200L.
Can a 1500W inverter start a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter)?
Yes — provided the 1,500W inverter is a pure sine wave unit with at least 900W of peak surge capacity (most quality 1,500W–1,800W LiFePO4 stations handle 3,000W–3,600W motor surges), it will safely start and run a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) (350W continuous).
What size generator or inverter do I need for a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter)?
Applying the NEC 20% continuous load safety headroom (420W continuous) and clearing the 900W startup surge requires a generator or battery inverter rated for at least 900 peak watts.
Does a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter) require a pure sine wave inverter?
Yes — a pure sine wave inverter (<3% THD) is strictly recommended for a Natural Gas / Propane Clothes Dryer (120V Drum & Igniter). Electronic moisture-sensing boards and silicon-carbide hot-surface gas igniters require clean 120V sine wave power.
