Customers are saying

Customers are positive about the 450VA Battery Back-Up System's long battery life, surge protection, and performance. Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    Was in need of a new UPS system and looking for a 650VA system. Since those were out of stock I got the 450VA. It does the job, but the only disadvantage is that this model does not have and USB connection to the computer so you can't check the status of the unit or test it from the computer. I kind of miss that.

    Not bad, not great. These last about 2 years and then they're dead. I suppose it's what to expect from a low budget UPS.

    I purchased this UPS for my parents' web surfing PC. I wanted something basic to help with the power drops they get during summer storms; those drops always manage to screw up their cable modem. So far no troubles, no trashed modems. Someone with a more powerful PC that they use for gaming or suchlike might want to look at a UPS with more wattage.

    When we were traveling overseas, I had devices plugged in all over the room in our hotel. I went into my son's room and he had a charger like this one. All of his devices were together (so none would get left!) and charging very quickly. When we got home, I bought one for myself. Next time charging won't be such an issue.

    Having just bought a new iMac desktop, power backup and surge suppression was important to me. We have had this for nearly a year and it has worked flawlessly. Through electrical storms and power outages this backup unit has met or exceeded our expectations. I would recommend this unit to a friend.jcs

    Needed a small UPS for my networking equipment - basically just a modem, router, and a backup HDD in an area that was suffering reoccurring spikes and brown outs. This was ideal for that purpose . CyberPower products have consistently offered better quality and value, in my opinion. I'd buy again for myself and recommend to anyone.
