Nobody wants to be at the mercy of a power outage in their home. Even a brief one that lasts only a few minutes is an annoyance because you have to go check on all your electrical appliances and reactivate them, as well as reset several clocks, the thermostat, and re-log into your Wi-Fi modem from several devices.
The real threat comes from extended power outages that can last for hours or even days. These can strike in extreme weather conditions or due to massive strain on the electrical grid. A household depends on electrical power in numerous ways, and losing that power will mean a loss of heating and air conditioning, the refrigerator, ways to charge mobile devices, computer connections, Wi-Fi connections, and more. When it comes to the HVAC system and powered medical equipment, power outages can turn into genuine emergencies.
