    APC Back ES-550VA UPS


    (Page 1 of 5 )

    Unfortunately, many people still neglect to use UPS devices. Many users don't even think about them until they absolutely need one -- such as right after their system failed because they didn't have one. So many purchasers put the UPS on the optional list when they're shopping for a new system. If you are an average home user and you want a UPS, then perhaps you should consider the APC Back ES-550VA UPS.

    Perhaps UPS devices are so underrated because of the following two factors. The first one, of course, is their price. A UPS isnít cheap, in part because itís made up of three parts, each one more important than the last: the power supply, the battery, and the inverter. With mass production, the price can be reduced, but the demand tends to be quite low.

    The other factor is that many believe in the safety provided by the nearby power plant, thinking that major negative issues wonít ever happen. Indeed, in many populated zones, power blackouts are so rare and occur for such short periods that few people worry about them. This is until they experience the frustration of owning a burned-out device thanks to a short over voltage, or lose critical data during a blackout.

    Since lately these kinds of scary scenarios have been happening more and more often (the network is overwhelmed by the increasing amount of devices plugged in almost non-stop), in recent years UPS devices have started to emerge for home users, and a slight price drop could be felt. Throughout this review Iím going to review one of these UPS devices targeted to home users, namely the UPS APC Back ES-550VA.
