220 Volt UPS Backup Battery Power.
Power outages don't care what kind of equipment you're running. The problem is, if your gear is 220 volts, a regular US backup battery won't do a thing for you.
These UPS units are built for 220v/230v power. They keep your electronics running through short outages and smooth out the voltage spikes that quietly wear down routers, computers, and anything else with sensitive circuitry inside. It's the kind of thing you don't think about until the power actually goes out, and by then it's too late to do anything but wish you had one.
