Another uninterruptible power supply of the same brand has been working for me for more than 12 years. ten years later, the battery ran out of service and was replaced. after which the UPS continues to serve faithfully. Pros: good uninterruptible power supply with a sufficiently large number of outlets and decent power. 6 out of 8 Euro sockets are provided with battery backup. Got cons: two of the eight euro sockets do not have battery protection. there is only a filter from high-frequency interference, which other outlets have.
