Ngokukhuphuka komdlalo weselula kanye nokusakazwa okushisayo kwedrama yewebhu, sizonikeza umakhalekhukhwini nsuku zonke, okubangela ugesi wehle, futhi imvamisa yokubhekana neshaja nayo yengezwe ngokuphawulekayo. Kuleli qophelo, kufanele unake izinkinga ezilandelayo. Ukuhleleka kokushaja okungokombono, ishaja esemthethweni akudingeki ukuthi icabangele le nkinga.

Kodwa-ke, uma kucatshangelwa ukuthi ishaja ifakwe kugesi, kuzoba khona umthelela wamanje, uma isokhethi yamandla noma ishaja ngokwayo inezingozi ezifihliwe zekhwalithi, kunethuba elincane lokubangela ukulimala kumakhalekhukhwini oxhunyiwe. Ngakho-ke, kunconywa ukuthi ukhethe i-oda lokushaja lesibili. Ngaphezu kwalokho, i-smartphone yokuqala iphinde yavela iphutha elifanayo, okungukuthi, xhuma ikhebula ledatha nefoni ephathekayo, bese uxhuma ishaja ne-outlet yamandla, futhi ekugcineni uxhume ikhebula ledatha neshaja.

Lesi simo esibucayi singenza iphutha leselula lifunde ulwazi lwesixhumi esibonakalayo se-USB + umugqa we-DD, okubangela ukuthi umakhalekhukhwini ukhombe imodi yamanje yokuxhuma nge-USB, ingafaka kuphela ngokusebenza kwamanje okungu-0.5A. Isiteshi seshaja sikholelwa ukuthi izicathulo zezingane eziningi zinombuzo ofanayo: Uma umakhalekhukhwini ungashajiwe, ishaja ihlala endaweni yokuphuma ugesi lapho iselula ingashajiwe.

Ayikhokhiswa yini? Noma kunjalo, umkhuba ka-Xiaobian ukuthi ishaja ihlezi ime endaweni yokuphuma kukagesi, ayikaze ihlukane. Ngakho-ke, lo mkhuba awufanele ukukhuthazwa? Impendulo ngokwemvelo inegethivu futhi ayikhuthazi. Ishaja ishiywe ku-outlet kagesi isikhathi eside.

Inqobo nje uma ishaja iyiqiniso, akukho bungozi bokuphepha emcabangweni. Kodwa-ke, ishaja yocingo oluphathwayo ifakwe kugesi, futhi kukhona uchungechunge lwezinqubo ezifana nokwehla, ukulungisa, ukuhlunga, noma ngabe ulayini wedatha awulayishwanga (awukho umakhalekhukhwini), kukhona nokulahlekelwa okuthile okungalayishiwe. Kube nabasebenzisi benethiwekhi ukuhlola ukulahleka okungalayishiwe kwamamodeli ahlukene weshaja yomakhalekhukhwini.

Umphumela uyisimo ezinsukwini ezimbili zeqhwa nomlilo: ukusetshenziswa kwamandla okuphansi okungalayishwanga kweshaja yeselula kungu-0.004W kuphela, futhi cishe akukho ukusetshenziswa kwamandla, futhi akukho ukusetshenziswa kwamandla Okuphakeme kakhulu kufika ku-1W! Lesi sibalo sivela kunethiwekhi ngamanye amazwi, ubukhulu beshaja yocingo buncike kwikhwalithi yayo, futhi ukusetshenziswa kwamandla okumaphakathi kwamashaja omkhiqizo kungalawulwa ngaphakathi kwe-0.1W, kanti enye i-cottage noma ikhwalithi iyakhathaza.

Ishaja, ukusetshenziswa kwayo kwamandla kungadabula umkhathizwe. Uma sithatha ishaja yamandla angenamthwalo we-1W njengesibonelo, ukusetshenziswa kwayo konyaka ongu-1 kungafinyelela kumadigri ayi-8.76, kubalwa ngokwezinga likagesi elingu-1, kanti isikweletu sikagesi sicishe sibe ngu-4.

38 yuan onyakeni o-1. Ngamanye amazwi, ukusetshenziswa kwamandla okungalayishi okumaphakathi kweshaja yocingo oluphathwayo (kubalwe ngokuya ngo-0.1 W) cishe ku-0.

438 yu. Lopeful? Kodwa sicela ungakhohlwa ukuthi ishaja yelungu ngalinye lomndeni weselula ingasebenzisa i-outlet yamandla. Ngaphezu kwalokho, inani labantu bezwe lami namuhla likhulu, futhi umuntu ngamunye ulingana nokulahlekelwa ngu-0.

438 yuan ngonyaka. Njengomuntu ngamunye, uma ngamunye wethu engakwazi ukuthuthukisa umkhuba weshaja yeselula (noma ukuvala ukunikezwa kwamandla kwesokhethi) uma ingashajwa, ingaba nomthelela wezenhlalakahle wesikhathi eside ofana nomhlaba. Ukuhambisana kweshaja kunjengoba kucacisiwe.

Uma umndeni usuqoqe amashaja ambalwa noma inqwaba yamaselula isikhathi eside, ingabe kufanele uthole ishaja yasekuqaleni ngaphambi kokushaja iselula yakho? Uma ishaja ixutshwe ngaphandle kwengozi? Lesi yisihloko sendoda endala, futhi igatsha elincane lizophinda futhi: inqobo nje uma lingumkhiqizi ojwayelekile, umakhalekhukhwini, ithebhulethi, isipikha esiphathwayo / se-Bluetooth, inqobo nje uma ishaja isekela i-voltage yokuphuma evamile engu-5V, khona-ke Ziyahambisana nomunye nomunye futhi zingashaja ama-smartphones. Isizathu silula kakhulu, umthamo we-voltage kanye nosayizi wamanje weshaja yeselula kungancika ekhonweni lesekhethi yokushaja yangaphakathi kwefoni ephathekayo kanye nebhethri ukuthi ibe yamanje. Kunesekhethi yokuvikela umsindo ngaphakathi kweshaja.

Uma i-current ephumayo isinkulu kakhulu, isekethe yokuvikela ingamisa okwesikhashana noma yehlise okukhiphayo kwamanje ukuze kuvinjelwe ingozi. Uma ifoni ephathekayo isekela kuphela okokufaka kwamandla we-5V / 2A, uyinikeza ishaja engu-5V / 4A, yakamuva ingakhipha kuphela i-current ye-2A; uma ifoni ephathekayo isekela okokufaka kwamandla angu-5V / 4A, ishaja ye-5V / 1A nayo ingayishaja, kodwa kuphela i-current ye-1A engakwazi ukukhipha i-1A kuphela, futhi ukusebenza kahle kuncishiswa ngo-75%. Ngamanye amazwi, ishaja yeselula yamamodeli emikhiqizo ehlukene ingahambisana, ukufanisa nje okungenangqondo kuzothinta isikhathi sokushaja kwefoni.

Ngokungeziwe ku-Qualcomm QC kanye ne-Lianfa PE kuyingxenye yendlela yokushaja okusheshayo yendawo yonke, ezinye izindlela zokushaja okusheshayo (njenge-VOOC, SFPC) zilungele kuphela izinhlobo zazo. Isibonelo, usebenzisa ishaja ye-flash ye-Oppovooc ukushaja ifoni ye-millet, yakamuva ingashaja kuphela izinga elijwayelekile le-5V / 2A, futhi ngokuphambene nalokho. Ngaphezu kwalokho, sisadinga ukuvimbela izimoto ezincane ze-Niu La, njenge-Take 5V / 0.

5A noma 5V / 1A ishaja yokushaja umakhalekhukhwini wakamuva. Njengoba iselula entsha isekela ukushaja okusheshayo, inqubo yokushaja izocupha ishaja isikhathi eside ukuthi isebenze ngamandla ayo aphezulu okukhiphayo, ukuze kube lula ukubangela ukushisa kweshaja ngokwayo. Ngalesi sikhathi, uma ishaja ngokwayo ingaphelele ngokwanele, ukushisa ngokweqile kwesikhathi eside noma amathuba amancane okuhlinzwa kuzoletha ingozi ethile yokuphepha.

Lapho omakhalekhukhwini bezungeza ku-inthanethi, babeqhuma, bashise, njll., ikakhulukazi okubangelwa ishaja yomuntu wesithathu ngenxa yekhwalithi ephansi.
