Zipangizo zamagetsi zomwe zakhudzidwa ndi magetsi otsika zimaphatikizaponso firiji, ozizira, mapampu amadzi, makina ochapira, ndi zowongolera mpweya.
Zinthu zathu zotetezera magetsi zimapereka njira yachuma komanso yothandiza kuthana ndi vutoli. Potenga Woteteza 220 Vala chitsanzo, tili ndi mtengo wotsogolera, tinene kuti mtundu wa fakitale ndi 165-250v. Mphamvu ikagwa pansi pa 165V kapena kupitirira 250v, malonda athu adzadula mphamvu yoteteza mphamvu kuti iteteze magetsi oteteza magetsi. Mphamvu ikangobwerera pamlingo wokhazikitsidwa, magetsi amabwezeretsanso.
