It will serve as a backup for the internet modem and camera. Full satisfaction so far. In addition to the low price, I was pleasantly pleased with the possibility of connecting to a PC via USB, good PC software in versions for Mac and Linux and the possibility of permanently turning off the sound alarm in case of power failure (via PC software or by a quick double press of the switch). From the software I am adding some screenshots, as for the remaining time on the screenshots when powered by battery, the UPS was connected to a 30 Watt modem adapter.

Purchased as a second piece. The first one went to silicon heaven after about 14 months after purchase on Alza. Just a few sparks and poof. But OK for the price.
The PC can keep alive for several minutes, long enough to save the distributed work.

Tested with a 40 W load and lasted 35 minutes, which corresponds to about 6 minutes at 50% load. But what the claimed power of 425 W means I do not understand. An absolute house number. For the price, but absolutely sufficient for backing up my NAS and router. The manual is very brief, I didn't read anywhere how to turn on the ECO mode or cancel the sound alarm (experimentally found that by double-clicking the power button)
Decent price
Sufficient power for small devices
A USB cable is missing in the package
Usb port on the front, why on earth
Power cable fixed
