Q: How to calculate the working time for your devices?
A: 1. AC output working time=2560wh * 0.85/the power of your device
For example, assume your power of device is 500W, working time
will be 2560wh * 0.85/500w=4.3 hrs (rough calculation)
2. DC and USB output working time=2560wh * 0.95/the power of your
device
Note
: The above data is for reference only. Backup time varies
with the power of different loads.
