What devices can be connected to this UPS?
Any 5 V devices: primarily 5 V CCTV cameras and other 5-volt devices.
Are batteries included?
No. The UPS uses standard 18650 batteries (1000–2000 mAh, 3.7 V), purchased separately at any specialized store.
How many batteries can be installed?
From 1 to 4. You choose the number of batteries yourself — this sets the total capacity and backup runtime.
How long does the backup power last?
It depends on the installed battery capacity and the power draw of the connected device: the more 18650 batteries installed, the longer it runs off-grid.
Does the UPS switch to battery automatically?
Yes, when mains power fails the UPS automatically switches to battery power, and the connected device keeps running without interruption.
