| Panasonic NN-SN67KS | 1,480W | 1,480W | Safe | ~0.6h | OEM Verified |
Show expert analysisTechnical: **Running load:** 1480 W continuous, no surge component. **Voltage requirement:** 120V AC. No surge margin needed since microwave magnetron presents constant resistive load during cook cycle. Field note: Generator must sustain 1480 W continuously for the full cook duration. Allow 200-300 W buffer to avoid voltage sag under sustained load. Can a 2000W inverter generator run this microwave? Only if your power source can supply at least 1480W continuous and 1480W surge at 120V. | |||||
| GE JVM3160RFSS (Over-the-Range) | 1,580W | 1,580W | Safe | ~0.6h | OEM Verified |
Show expert analysisTechnical: **Running load:** 1580 W. **Surge:** 1580 W. **Voltage:** 120V AC. No inrush current shown, meaning magnetron startup may still spike momentarily. Generator must deliver at least 1600 W continuous at 120V. Field note: Verify generator rated output matches or exceeds 1600 W continuous. Inverter models handle microwave loads more smoothly than older brushed designs. Will a 2000 W generator run this microwave? Only if your power source can supply at least 1580W continuous and 1580W surge at 120V. Confirm nameplate voltage and avoid overloading with simultaneous devices. | |||||

Show expert analysisTechnical: **Running load:** 1920 W. **Surge:** 1920 W. **Voltage:** 120V AC required. No surge multiplier observed, indicating resistive heating element without compressor or motor start transient. Generator must supply continuous 1920 W at 120V. Field note: Verify generator can sustain 1920 W continuously without derating. Heating appliances do not tolerate undervoltage. Confirm 120V output stability under full resistive load before connecting. Can I run this microwave on a 2000W generator? Only if your power source can supply at least 1920W continuous and 1920W surge at 120V. Verify the rated capacity accounts for altitude and temperature derating. | |||||

Show expert analysisTechnical: **Running load:** 1920 W. **Surge:** 1920 W. **Voltage:** 120V AC. No surge multiplier indicates resistive heating element. Generator must sustain continuous 1920 W output without voltage sag. Field note: Confirm generator continuous rating exceeds 1920 W with margin. Voltage regulation critical for magnetron longevity under sustained draw. Can I run this microwave on a 2000-watt inverter generator? Only if your power source can supply at least 1920W continuous and 1920W surge at 120V. Verify nameplate continuous rating, not peak marketing claims. | |||||

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 1920 W continuous. Surge: 1920 W (no additional inrush). Voltage: 120 V AC. Generator must supply at least 1920 W at 120 V with sufficient reserve for stable magnetron operation.
Expected Behavior
Estimated runtime: ~0.5h. Draws constant resistive load during cook cycles. Operates 0.5 hours daily, consuming approximately 960 Wh per day. Magnetron cycles on and off to maintain power level.
Field Note
Ensure generator can sustain 1920 W without voltage sag. Momentary brownouts may cause magnetron shutdown or uneven heating.
Frequently Asked Questions
Can the EcoFlow DELTA (Gen 1) power a Microwave Oven (1000W)?
It depends on the model. 2 of 4 Microwave Oven (1000W) models are compatible with the EcoFlow DELTA (Gen 1). See the model-specific results table for exact verdicts per model.
How long will the DELTA (Gen 1) run a Microwave Oven (1000W)?
