Router UPS

Uninterruptible power supply when connecting the router, all the lights start flashing and turns off. Charged to 100 percent and still the same. I will see what the problem is, whether it is in the cable or in the uninterrupted one itself. Then I will add a review.

The quality is super, in working order, everything works, the box is not damaged, we will order another one, the Internet works with or without light
