Explanation
A battery backup (also called a UPS - Uninterruptible Power Supply) contains an internal battery that provides continuous power to connected devices during both power surges and outages. It switches to battery instantly so connected devices experience no interruption. A surge suppressor only protects against voltage spikes and provides no power during an outage. A power strip offers no power protection at all. A line conditioner stabilizes power quality but does not supply power when the source is lost.
