Fundo yakugwira ntchito ya charger

Ma charger ghose gha foni ghakupangika nadi na magesi ghakukhazikika (chomenechomene magesi {{ - magesi ghakukhazikika, kupereka nkhongono zakugwira ntchito zakugwira ntchito na magesi ghakukwana) kusazgapo nyengo zose zakukhumbikwa, mphaka ya magesi, kuchepeska nyengo, nyengo yakujumpha, kujumphirapo na vinyake vyakulongozga.
Vigaŵa vyakufumamo ivyo vikulembeka pa charger yakwamba (kuyowoya za charger ya mzere): nga ni ivyo vikufumamo 4.4V / 1A, ivyo vikufumamo 5.9V / 400mA, wonani vigaŵa vyakukhwaskana na magesi gha mukati -} vyakukhazikika. Mwachiyelezgero, ivyo vikufuma mu 4.4V vingagwiliskirika ntchito pa vipangizo vya 4.5V, ndipo 5.9V yingagwiliskirika ntchito pa vipangizo vya 6V.
