Can a Power Station Run a Microwave?
Yes, if the box gives at least as many watts as your microwave pulls, which is about 1,500 watts for a 1,000-watt microwave; on their normal output, small boxes of 300 to 800 watts can't run one.
Yes, a power station can run a microwave if it gives at least as many watts as the microwave pulls, which is about 1,500 watts for a 1,000-watt microwave. A microwave pulls more power than the number on its door, so on their normal output, small boxes of 300 to 800 watts can't run one.
By our math, a 1,000-watt microwave on a box like the BLUETTI AC180 (1,152 Wh, 1,800 W) gets about 39 minutes of cooking per charge. To try a full list of devices, use Find My Power.
Two words first
- Watts: how fast something uses power. This decides if a box can run the microwave at all.
- Watt-hours: how much power a box holds. This decides how many minutes you get.

How many watts does a microwave use?
The number on a microwave is its cooking power, not what it pulls from the outlet. Honda's generator wattage guide lists these numbers:
| Microwave (cooking power) | What it pulls (Honda) |
|---|---|
| 650 watts | 1,000 watts |
| 800 watts | 1,300 watts |
| 1,000 watts | 1,500 watts |
Honda's guide lists the same number to start and to run, so a microwave has no big start-up burst like a fridge. If your microwave's label lists the watts it draws, use that number instead.
In Find My Power we count a microwave at 1,100 watts running, which falls between a 650-watt and an 800-watt microwave in Honda's table. Find also checks for 1,500 watts at the start, to be safe. So Find shows more minutes than this guide does for a 1,000-watt microwave: about 0.9 hours (about 53 minutes) on the AC180 instead of 39 minutes. If your microwave is a 1,000-watt one, use the 1,500-watt numbers here.
What size power station do I need for a microwave?
Look at two numbers on the box:
- Its watts (output). This has to be at least what your microwave pulls. If not, the box shuts off.
- Its watt-hours. This sets how many minutes of cooking you get.
Here is how four of the boxes we list near 1,000 Wh line up. Minutes are by our math, for one microwave and nothing else plugged in.
| Box | Holds | Gives | 650 W microwave (1,000 W pull) | 800 W microwave (1,300 W pull) | 1,000 W microwave (1,500 W pull) |
|---|---|---|---|---|---|
| BLUETTI AC180 | 1,152 Wh | 1,800 W | about 59 min | about 45 min | about 39 min |
| Jackery Explorer 1000 v2 | 1,070 Wh | 1,500 W | about 55 min | about 42 min | about 36 min, no room to spare |
| Anker SOLIX C1000 Gen 2 | 1,024 Wh | 2,000 W | about 52 min | about 40 min | about 35 min |
| EcoFlow DELTA 3 | 1,024 Wh | 1,800 W | about 52 min | about 40 min | about 35 min |
Estimates. Your devices may use more or less. With no room to spare, a box may shut off if the microwave pulls a bit more than Honda's number.
The math we use across the site:
Minutes = watt-hours × 0.85 ÷ watts × 60
We keep 85% of the watt-hours because some power is lost on the way out. For the AC180 with a 1,000-watt microwave: 1,152 × 0.85 ÷ 1,500 × 60 = about 39 minutes.
What about small boxes?
A box like the EcoFlow RIVER 3 Plus gives 600 W. That is less than even a 650-watt microwave pulls, so by our math it can't run one.
The EcoFlow RIVER 2 Pro gives 800 W. EcoFlow says its X-Boost mode can go up to 1,600 watts and names a microwave as one use for it. X-Boost is a special mode, not the box's normal 800 watts, so we don't count it in our math. If a microwave is on your list, we would pick a box that gives 1,500 watts or more without it.
Our pick for a microwave
We would pick the BLUETTI AC180. It gives 1,800 W, enough for a 1,000-watt microwave. It holds 1,152 Wh; the C1000 Gen 2 holds 1,024 Wh and the DELTA 3 holds 1,024 Wh. More watt-hours means more minutes of cooking.
If you want more room above 1,500 watts, the Anker SOLIX C1000 Gen 2 gives 2,000 W. It holds a bit less, so you get a few minutes less per charge.

Tips for cooking in an outage
- Turn off other big things while the microwave runs. Its watts add up with everything else plugged in.
- Short reheats cost little. By our math, 3 minutes at 1,500 watts uses about 88 watt-hours from the box.
- If you also need the fridge, save a big part of the box for it. Our fridge guide shows how long a fridge runs.
- A space heater can pull as many watts as a microwave, but it runs for hours. Read space heater watts before you plan on one.
- For a full storm plan, see our winter storm checklist.
Questions people ask
Can a 300W power station run a microwave?
No. By Honda's numbers, even a 650-watt microwave pulls about 1,000 watts. A 300-watt box shuts off before the microwave can run.
How many watts does a microwave use?
More than the number on the door. Honda lists about 1,000 watts for a 650-watt microwave and about 1,500 watts for a 1,000-watt microwave.
How long can a power station run a microwave?
By our math, a box near 1,000 Wh gives a 1,000-watt microwave about 35 to 39 minutes. A reheat often takes a few minutes, so that is many meals, not one long cook.
Can I run a microwave and a fridge at the same time?
On a box that gives 1,800 watts, often yes, but it can be close. The fridge needs a burst of power when its motor starts, on top of what the microwave pulls. Put both in Find My Power and it checks the start-up burst for you.
