If you own a desktop computer, which is an investment or an appliance of value, you may want to invest in purchasing a UPS (uninterrupted power supply). An uninterruptible power supply (UPS), offers guaranteed power protection for connected electronics. When power is interrupted, or fluctuates outside safe levels, a UPS will instantly provide clean battery backup power and surge protection for plugged-in, sensitive equipment. Typically, during a power outage, the UPS will keep the equipment stable for a prescribed amount of runtime (depending on the type/model UPS you install). The time element gives you enough time to safely shut down the computer to prevent component damage and loss of data. Many UPS will come with a bank of outlets. For example, I own the APC UPS Battery Backup & Surge Protector 650 which gives me a total of 8 outlets (4 on each side of the UPS). The important part to note here is that 4 of those outlets provide “battery back up & surge protection” and the other 4 provide on (surge protection). I typically plug in the computer, monitor, router, and modem into the battery backup side and other less significant devices (such as a printer) in the other surge protection outlet. This particular UPS (APC UPS Battery Backup & Surge Protector 650) is rated for approximately a half hour of runtime during a complete outage.
In the end, investing in one of these is like having an insurance policy that will help keep your computer and electronics running smoothly, even during those times when you have power fluctuations and outages.
