Uninterruptible power supplies for Wi-Fi are exploding en masse in apartments in Ukraine As Yoro found out, devices began to be actively purchased in Ukraine during outages - they are connected to routers so as not to be left without the Internet. Now the owners are complaining about dozens of cases where they exploded non-stop, some in the middle of the night. As a rule, before "self-destruct", problematic devices overheated quickly. One girl's uninterruptible power supply went off while she was sleeping. A fire broke out in which the clothes burned. For another user, one of the four batteries exploded - leaving nothing left of the device itself. After such stories, many owners are simply afraid to turn on their devices, preferring to remain without communication.
