Εξαιρετικό. Δούλεψε απροβλημάτιστα όταν χρειάστηκε. Προστατεύει μόνιμα , ένα desctop PC και ένα NAS.

Έχει τον όγκο του και δεν είναι και ο,τι πιο όμορφο για να σταθεί πάνω σε ένα γραφείο, οπότε το έχω τοποθετήσει κάτω από το γραφείο.
Υποστηρίζει τέσσερις συσκευές στη μπαταρία και τέσσερις για προστασία από υπερτάσεις. Έχει και προστασία δικτύου και τηλεφωνικής γραμμής, αλλά δεν μπορούν να δουλέψουν και τα δύο μαζί.
Το πρόγραμμα διαχείρισης έχει αρκετές επιλογές και σενάρια λειτουργίας και λειτουργεί άψογα.
Επίσης, έχει μια έξυπνη λειτουργία master-slave, όπου τρεις από τις "απλές" υποδοχές ελέγχονται από μία κεντρική. Για παράδειγμα, έχω βάλει στη "master" υποδοχή το PC και στις slave τα ηχεία και μια ακόμα συσκευή και κάθε φορά που σβήνω το PC σβήνουν αυτόματα και αυτές οι συσκευές (είναι παραμετροποιήσιμη και αυτή η λειτουργία μέσω του προγράμματος).
Την πρώτη φορά που θα το βγάλετε από το κουτί θα πρέπει να συνδέσετε τον αρνητικό πόλο της μπαταρίας!
Η εκτιμώμενη αυτονομία που δείχνει το πρόγραμμα με τη μπαταρία 100% φορτισμένη και έχοντας ένα PC, μια οθόνη και έναν εκτυπωτή είναι 15'.
Από τα καλύτερα που μπορείτε να αγοράσετε.

Purchased a year ago, maybe more, I finally found time to untangle the cables of the old power strip (a reliable Belkin with surge protection) and set up the APC. Good device, quality construction, heavy but compact. I placed it on the desk, with the PC and monitor connected to the UPS, and 5-6 other devices plugged into the regular outlets.

Supposedly, it provides 5-8 minutes of operation to save and shut down the PC smoothly. The interesting part will be when it does it on its own. The software is very good, with rich customization options.

I don't have any incidents to report yet. I will come back in the future, even with a simulated power outage.

2/7/2020: After 3 weeks of use, everything is fine. The software is very good - with 100% charge, it supposedly provides 23 minutes of usage in case of a power outage. Sufficient time to shut down everything smoothly. Of course, with a powerful GPU, the time will be shorter. Soon, I will install a 1080Ti and see if it changes (currently using the CPU's GPU - i5-8600K with stock clock). However, in these 3 weeks, there were 2 momentary voltage drops where the UPS provided power for a few seconds. I will come back with an artificial power outage.

01.03.2022: It continues to work perfectly, without having changed the battery yet. It has intervened several times. Good purchase.

03-12-2022: Today I had a few blackouts and it worked for about 27 minutes on battery. I turned off the monitor, of course - the PC was just open in a file manager. When the power came back, the application said the battery was at around 38%. It seems to provide power for quite a few minutes (it now says 40% with a fully charged battery). I couldn't see it shut down the PC as I have set it to do so at 5%.

07-09-2023: Most likely, it's time for a new battery as the PC has been shutting down during power outages for a month now. Today, with the thunderstorms, it shut down 3 times in as many lightning strikes.

It is completely noisy. Most UPSs make noise due to the fan.
The weight with the battery is about 8 kilograms. It lasts for 8 minutes for a 15-inch laptop with a 24-inch screen and 2 external hard drives.
The battery needs to be replaced after 3 to 4 years and costs 25 euros.

The UPS does what it promises, effectively protecting a television, a media player, a satellite receiver, a router, and a small server with 2 disks. Completely satisfied with the purchase and its small height which is ideal for use in a limited space around a television.

It does what it promises. And if you connect it to a computer, it installs the accompanying software automatically, so you don't need to do anything else... it will shut down automatically. You only have to deal with any other devices you have connected to the power strip.
