BATTERY RUNTIME ESTIMATOR
RunTime 1.0
The CamWise Battery Runtime Estimator helps you quickly calculate how long a camera or rig will run on a given battery setup. Enter battery watt-hours, your camera’s power draw, and any accessories like monitors or transmitters to estimate total runtime in hours and minutes.
Tip: Use this tool to plan battery swaps, estimate shoot-day power needs, or compare the efficiency of different power setups. You can choose from popular camera presets or enter your own measured wattage for the most accurate result.

After calculation, results will show total draw, total available watt-hours, and estimated runtime in hours and minutes. Values are estimates.
Frequently Asked Questions
They’re close enough for planning but should not replace real-world testing. Actual runtime depends on factors like screen brightness, codec and resolution, wireless transmission range, and ambient temperature. Voltage conversion losses can also shorten usable runtime, which is why the efficiency field defaults to 90%.
Yes. Enter any device’s wattage instead of choosing a camera preset, and the tool will calculate runtime the same way. Just be sure to include all accessories powered from the same source to get a realistic total draw.
You can increase the “Number of batteries” field to see your total available runtime across all packs. This helps estimate a full shoot day or continuous rig operation when cycling multiple batteries.
