How to clean up mains power?
But again, that $85 retail UPS does not 'clean' electricity. It
connects appliance directly to AC mains when not in battery backup
mode.
"Jamie" implied that it is a "dual-conversion" type:
"It has a 120 watt inverter that runs all the time and the 120 volts [input]
does nothing but keep the battery charged."
