What is the name of the battery backup power supply
In addition to acting as a backup when the power goes out, most battery backup devices also act as power "conditioners" by ensuring that the electricity flowing to your computer and accessories is free from drops or surges. If a computer isn't receiving a consistent flow of electricity, damage can and often does. The battery backup sits between the utility power (power from the wall outlet) and the parts of the computer. In other words, the computer and accessories. The front of the battery backup will usually have a power switch to turn the device on and off and will sometimes have one or more additional buttons.
