FAQ

Q1.Ngingalithola isampula le-oda le-filimi capacitor?
A: Yebo, siyakwamukela uku-oda kwesampula ukuze sihlole futhi sihlole ikhwalithi.Amasampuli ahlanganisiwe ayamukeleka.
Q2.Kuthiwani ngesikhathi sokuhola?
A: Isampula idinga izinsuku ezi-3-5, isikhathi sokukhiqiza ngobuningi sidinga amaviki angu-1-2 ngenani le-oda elingaphezu kwalokho.
Q3.Ingabe unawo umkhawulo we-MOQ wama-fim capacitor?
A: I-MOQ ephansi, i-1pc yokuhlola isampula iyatholakala.
Q4.Ungawenza kanjani i-oda lama-capacitor wefilimu?
IMP: Okokuqala sazise izidingo zakho noma isicelo sakho.
Okwesibili Sicaphuna ngokwezidingo zakho noma iziphakamiso zethu.
Okwesithathu ikhasimende liqinisekisa amasampula kanye nediphozi yezindawo ukuze uthole i-oda elisemthethweni.
Okwesine Sihlela ukukhiqizwa.
Q5.Uzithumela kanjani izimpahla futhi kuthatha isikhathi esingakanani ukufika?
A: Ngokuvamile sithumela nge-DHL, i-UPS, i-FedEx noma i-TNT.Ngokuvamile kuthatha izinsuku ezingu-3-5 ukufika.Ukuthunyelwa kwezindiza nolwandle nakho kuyakhethwa.
Q6.Ingabe kulungile ukuphrinta ilogo yami kuma-capacitor?
A: Yebo.Sicela usazise ngokusemthethweni ngaphambi kokukhiqizwa kwethu futhi uqinisekise umklamo kuqala ngokusekelwe kusampula yethu.
Q7: Ingabe uyasinikeza isiqinisekiso semikhiqizo?
A: Yebo, sinikeza iwaranti yeminyaka engu-7 emikhiqizweni yethu.
