The run time of the NOQUA Pro Power battery depends on the draw of the device.
Check with the device manufacture for the average draw. Make sure to note the units – the draw will either be listed in Ah (amps per hour) or mAh (milliamps per hour).
Once you have that number and keeping the units consistent, divide the draw by the capacity of the Pro Power Kit (i.e. 10Ah or 10,000mAh/4.4Ah or 4,400mAh).
The number remaining will be the average run time in hours of the device powered by a fully charged NOCQUA Pro Power Battery.
