A: Yes! One of the standout in the D3-1000 is the Uninterruptible Power Supply (UPS) feature. When the unit is connected to a wall outlet and your device is plugged into the AC port, it enters "bypass mode". If the grid goes down, the power switches to the internal battery in just 20ms, keeping your router or PC from rebooting.

A: Working time = 1004.8Wh* 0.85 / operating wattage of your device
For reference, assuming power consumption of your device is 30W (might be a box fan), working time will be 1004.8Wh*0.85/30W=28.4hrs (rough calculated) .
Please note: actual power consumption varies from different usages, please consult Jackery for better purchase decision.

A: Please wipe the D3-1000 with a dry, soft, clean cloth or paper towel.
