M'masiku onse osokoneza magetsi, zowopsa zamphamvu zamphamvu zapamwamba zimaphatikizapo kukalamba kwa zida zamagetsi ndi kuchepetsedwa. Ngati mphamvu yamphamvu imapitilira zingapo, imatha kuwononga mwachindunji mwachindunji zida zamagetsi monga ma TV, DVD, Spires, Steres, ndi zina zambiri, zoopsa zomwe zimayambitsa kuwonongeka kwa zida kapenanso zoopsa moto.

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 kupitilira 250V, malonda athu adzadula mphamvu yoteteza mphamvu kuti iteteze zida zamagetsi. Mphamvu ikangobwerera pamlingo wokhazikitsidwa, magetsi amabwezeretsedwa okha.
