hahahaha.mao nalang wala ko ni kagat ana mga Power Saver device. Pero actually my friend said that tinood daw ni and dugay na daw ni gamit sa mga large manufacturing company are most especially company that uses lots of motors ( furniture company) but this is already built-in sa ilang power supply system...Basin gi-emitate tingali ni bro..
Beware aning mga power saver na i-parallel sa imong source this power saver daw is only working if full load imong system pero if dili mo-consume na hinoon ni cya ug current. Thanks for the people in istorya who cares..hehehe..
Concusion: In order to save current off any system that are not in used..
or do not uses at all..heheh
