Amabhethri e-USB aphinde ashajwe ngokuvamile enziwa ngobuchwepheshe be-lithium-ion, obunikeza ukuminyana okukhulu kwamandla nokusebenza okuhlala isikhathi eside. Zenzelwe ukuthi zibe compact futhi zilula, okwenza kube lula ukuzithwala esikhwameni noma ephaketheni.
Ukushaja aamabhethri e-usb ashajwa kabushaibhethri, udinga nje ukuyixhuma kumthombo wamandla we-USB, njengekhompyutha, i-adaptha yodonga, noma ibhange lamandla, usebenzisa intambo yokushaja. Ibhethri ivamise ukuba nenkomba yokushaja eyakhelwe ngaphakathi ekhombisa isimo sokushaja, futhi ingashajwa ngokugcwele emahoreni ambalwa.
Iqeda isidingo samabhethri alahlwayo futhi ikugcinele imali ngokuhamba kwesikhathi. Amanye amabhethri e-USB aphinde ashajwe aze afika nezimbobo eziningi, okukuvumela ukuthi ushaje amadivayisi amaningi ngesikhathi esisodwa.
Sekukonke, aaaa amabhethri e-usb aphinde ashajweiyisixazululo samandla esisebenziseka kalula futhi esisebenziseka kalula esihlinzeka ngokushaja okuphathekayo kwezinhlobonhlobo zemishini kagesi.
