A UPS or a " battery back up" is a device that has a 12 volt battery that is always being charged via commercial power.
It will produce 110 volts via the inverter and the battery.

This method of producing power is a cleaner power and will help protect your vital equipment like computers and gaming equipment.

It will also produce power when there is no commercial power due to a storm or something.

We installed one for our fiber ont and internet router to keep our internet and phone up and working when the power goes out.
