CyberPower CP1500AVRLCD3-R UPS System

I use it for my home computer system. Be sure to follow the instructions precisely when it comes to connecting devices to this unit. Only connect what you really need in the event of a power outage, to the powered outlets. Computer, modem, monitor, even a small desk lamp/light. Follow the instructions and DO NOT connect devices like laser printers as they require a large power output to operate, and will create a major drain on this device, even if they're not printing anything. Besides, how often do you have to print documents that you need power to your printer at all times? I connected my printer and stereo speakers to a separate power strip connected to a different outlet in the room. The software disc that comes with it installs easily, and adds a monitor display screen to your task bar. This can be opened to show the power available from the unit, should you lose power, as well as, the power drain that would be in effect to the devices you have attached, and your total battery time remaining based on devices that are connected. You can run diagnostic tests to make sure it's fully functional. You can also configure the alarm and software sounds, the length of time your computer runs on battery, and voltage controls for the tolerance of your UPS to voltage flucuations. Simply put, if you have too many devices plugged in and the power drain exceeds the power available, your backup power will drain much faster, and some devices, like your computer, may suffer from a hard crash resulting in lost data that you did not have time to save. You get nine outlets for your devices. A column of five powered/surge protected outlets on one side, and a column of four surge protection only (non-powered) outlets on the other side. In the center you have phone line in/out ports, coax in/out ports, and a reset button. Above the column of four non-powered/surge protect only outlets is the interface port for connection to one of your computers USB ports. A USB cable, Phone cable and Power Cord for this unit are included. So may sure you have an available USB port on your computer! Directions tell you to plug the unit in by itself to charge it up, before connecting your devices. Lucky for me, mine was already fully charged, so my setup only took a few minutes. I don't know how long it would take to charge it up fully from a depleted state, so don't expect to put it right to use, just out of the box. Afterall who knows how long yours was packaged and sitting on a shelf somewhere before it was shipped to the store, and/or to you. The only drawback I can foresee is that not all power plugs are shaped the same and you may find yourself doing some fancy maneuvering of power plugs on the back of this device, to make sure you connect all that you want to. Large/Wide power plugs attached at the top, or in the center, may block access to the coax and/or phone line ports. I don't use any coax connections so I didn't mind blocking one of mine. As always, keep the instruction book, as it contains information about how to order replacement batteries for this unit.
