Incazelo emfushane:
I-power bank iyisisetshenziswa se-elekthronikhi esiphathwayo esingadlulisa amandla ukusuka kubhethri elakhelwe ngaphakathi ukuya kwamanye amadivaysi.Lokhu ngokuvamile kwenziwa ngembobo ye-USB-A noma ye-USB-C, nakuba ukushaja okungenantambo nakho kuya ngokuya kutholakala.Amabhange kagesi asetshenziselwa kakhulu ukushaja amadivaysi amancane anezimbobo ze-USB ezifana nama-smartphone, amaphilisi nama-Chromebook.Kodwa futhi zingasetshenziswa ukwengeza izinsiza ezahlukahlukene ezisebenza nge-USB, okuhlanganisa ama-headphone, izipikha zeBluetooth, amalambu, izifeni namabhethri ekhamera.
Amabhange kagesi ajwayele ukushajwa kabusha ngokunikezwa kwamandla e-USB.Abanye banikeza ukushaja kokudlula, okusho ukuthi ungashaja amadivayisi akho ngenkathi ibhange lamandla ngokwalo lishaja kabusha.
Ngamafuphi, uma iphezulu inombolo ye-mAh yebhange lamandla, yilapho iletha amandla engeziwe.
Inani le-mAh liyinkomba yohlobo lwebhange lamandla kanye nomsebenzi walo: Kufika ku-7,500 mAh - Ibhange lamandla elincane, elingena ephaketheni elivame ukwanele ukushaja i-smartphone ngokugcwele kusukela kanye kuze kube izikhathi ezi-3.
Ngenkathi lawa mayunithi eza ngazo zonke izinhlobo nosayizi, aphinde ahluke ngomthamo wamandla, njengezinhlobonhlobo zama-smartphones emakethe.
Igama ovame ukulibona ngenkathi ucwaninga lawa mayunithi yi-mAh.Kuyisifinyezo se-“milliampere hour,” futhi kuyindlela yokuveza umthamo kagesi wamabhethri amancane.U-A unosonhlamvukazi ngoba, ngaphansi Kohlelo Lwamazwe Ngamazwe Lwamayunithi, i-“ampere” ihlale imelwe ngosonhlamvukazi A. Ukuyibeka kalula, isilinganiso se-mAh sibonisa umthamo wokugeleza kwamandla ngokuhamba kwesikhathi.
