Input watts vs cooking watts
A 900 W microwave can draw more than 900 W from the outlet. The calculator uses electrical input watts because that is what the power station must supply.
Specialized runtime calculator
Microwave Power Station Runtime Calculator
Estimate whether a power station can run a microwave, how many heating cycles you can get, and what battery size you need.
Microwaves are better modeled by cooking sessions than by continuous hours. Use the electrical input watts from the nameplate when possible.
1
What are you powering?
Choose the device or setup.
2
Tell us what you know
Use the easiest available input.
3
Choose your power station
Enter battery and output limits.

Review runtime, checks, and matches.
Can my power station run my microwave?
Tell us what you know
Enter the microwave input watts and how long each use lasts.

+ Battery and output assumptions
Cycles matter more than hours
Most people use a microwave for short sessions, so estimated number of uses is more useful than continuous runtime.
Microwave Power Station Runtime Calculator FAQ
Can a 1000Wh power station run a microwave?
It depends on the station's continuous AC output and the microwave input watts. Capacity affects how many uses you get; output determines whether it can run at all.
Should I use cooking watts or input watts?
Use electrical input watts from the label or manual. Cooking watts are useful context but not the power draw from the battery.
Accuracy notes
This calculator estimates electrical runtime and sizing. Actual results can change with device model, load variation, battery age, temperature, inverter idle draw, charge level, reserve settings, and manufacturer limits. Verify safety-critical loads with the device and power station documentation.
