Automated voltage regulation (AVR): Also referred to as line-interactive topology, that is a additional Highly developed kind of power management that makes use of a little transformer to be a buffer to compensate for electrical power dips and surges without the need of counting on the battery.
It backs up 5 of its 10 stores having a battery, and it's a six-foot wire. Its compact form—about the size of a jumbo a few-ring binder standing upright—makes it comparatively very easy to stow below a desk or nightstand.
