Heating up food during an outage is a real comfort — and yes, a power station can run a microwave, if it is big enough. Here is exactly what you need.
The short answer
Microwaves are heavy, surging loads. A “1000 W” microwave actually draws ~1500 W from the outlet (cooking watts are output, not input). So you need a power station with an 1800 W inverter, like the Bluetti AC180. A 1 kWh unit powers a microwave for many short heatings — it is the brief, high-draw use that matters.
Microwave power: output vs input
| Microwave (cooking watts) | Actual input draw | Runs on an 1800W unit? |
|---|---|---|
| 700 W | ~1100 W | Yes |
| 1000 W | ~1500 W | Yes |
| 1200 W | ~1700–1800 W | Borderline |
The mismatch trips people up: a 1000 W microwave needs ~1500 W of input, so a 1000 W power station cannot run it. Always size to the input draw.

Same 1800 W output, expandable to 3 kWh if you want a microwave plus a fridge during a long outage.
Frequently asked questions
Can a power station run a microwave?
Yes — with an 1800 W inverter. Remember a 1000 W microwave draws ~1500 W input, so a 1000 W unit is not enough.
How long can it run a microwave?
Microwaving is brief, so a 1 kWh unit covers many heatings — roughly 40 minutes of continuous run time total, which is a lot of 2–3 minute meals.
Why does my 1000W microwave need an 1800W unit?
The 1000 W rating is cooking output; the magnetron is only ~60% efficient, so it pulls ~1500 W from the outlet.
