Iningi lamadivayisi akho manje selishaja ngezimbobo ze-USB ngaphandle kwemishini yokushaja okungenantambo, ngoba ukushajwa kwe-USB kuguqule indlela esicabanga ngayo ngamandla, futhi kwenze kwaba lula ukushaja amadivaysi ahlukahlukene.Kulula kakhulu uma ikhompuyutha yakho ephathekayo, ithebhulethi noma i-smartphone yabelana ngamandla afanayo, okudingayo nje isokhethi le-USB elinezimbobo eziningi kanye nezintambo ezimbalwa ze-USB ezihambisanayo ukuze uxhumeke.Kwesinye isikhathi usadinga i-adaptha eyodwa ye-USB AC uma imbobo yokushaja ingafani nezimbobo ze-USB.Ngokwazi kwethu, imishini kagesi ephathwayo isiyatholakala ukuthi ishajwe kanyekanye ngoba ama-adaptha odongeni, amashaja ezimoto, amashaja edeskithophu ngisho namabhange kagesi manje asekela lokhu kusebenza.Ingabe singawubona lo msebenzi uma kuziwa ezintweni zikagesi?Asihambe siyoxoxa ngalokho esikuthola emakethe.
Izindaba ezinhle ukuthi izindawo eziningi zikagesi seziyatholakala nezimbobo ze-USB ezakhelwe kuzo.Izitolo ze-USB bezilokhu zisemakethe yokushaja izinto zikagesi iminyaka eyishumi.Ngenxa yobuchwepheshe be-USB obukhula ngokushesha, ubuchwepheshe bokushaja okusheshayo manje busetshenziswa kabanzi ukushaja, ikakhulukazi kubuchwepheshe be-QC 3.0 kanye ne-PD, businikeze isivinini esimangalisayo.Uma usashaja embobeni endala ye-USB Type-A, awusitholi isivinini sokushaja esingcono kakhulu samadivayisi akho amasha.
Ungayikhetha kanjani i-USB Wall Outlet
Kulula kakhulu ukukhetha i-USB wall outlet namuhla.Akudingekile ukuba ube nguchwepheshe kagesi uma udinga ukuthenga i-USB wall outlet.Lokhu akusho ukuthi kufanele ube budedengu.Sicela uhlole izisetshenziswa zakho zikagesi futhi ubone ngokucacile ubuchwepheshe bokushaja obuhambisana nabo ngaphambi kokuthenga.
I-USB Power Delivery (USB PD) vs. QC 3.0 Ukushaja
Empeleni, iningi labathengi alicaci kahle mayelana nomehluko phakathi kokushaja kwe-USB Power Delivery (PD) ne-QC (Quick Charge) 3.0.Bobabili lobu buchwepheshe bokushaja okusheshayo ngembobo ye-USB obusebenza ngokushesha kune-USB evamile.Wonke amadivayisi e-PD angashajwa kuphela ngembobo ye-USB-C™ kuyilapho amadivayisi wokushaja we-QC angashajwa ngazo zombili izimbobo ze-USB-A ne-USB-C.Ngamanye amazwi, udinga ukwazi ukuthi yiluphi uhlobo lwamandla oluthathwa yidivayisi yakho ngaphambi kokuthenga i-USB.Sekushiwo lokho, amanye amadivayisi empeleni asekela ubuchwepheshe bokushaja be-PD ne-QC.Uma kunjalo, udinga ukuthola ukuthi iyiphi engcono.
Imbobo ye-USB evamile ayikwazi ukuletha amandla angaphezu kuka-10 watts.I-USB Power Delivery amadivayisi anephrothokholi yokushaja engaletha kufika kuma-watts angu-100(20V/5A), lokhu ngokuvamile kudingwa ikhompuyutha ephathekayo esekela i-USB PD.Ngaphandle kwalokho, ubuchwepheshe be-USB PD buphinde busekele amawathi wokushaja ahlukene njenge-5V/3A, 9V/3A, 12V/3A, 15V/3A kanye ne-20V/3A.Ku-smartphone noma ithebhulethi, sonke isidingo samandla singaba ku-12V esiphezulu.
Ubuchwepheshe be-PD bathuthukiswa yi-USB Implementers Forum.Ukushaja kwe-PD kungatholakala kuphela uma izinto zakho zikagesi, ikhebula le-USB nomthombo wamandla konke kusekela lobu buchwepheshe.Isibonelo, i-smartphone ngeke ithole ukushaja kwe-PD uma i-smartphone yakho ne-adaptha yamandla isekela i-PD kodwa ikhebula lakho le-USB-C lingayisekeli.
I-QC isho Ukushaja Okusheshayo okwasungulwa yi-Qualcomm kuqala.Okusho ukuthi, i-QC isebenza kuphela uma idivayisi isebenza ku-chipset ye-Qualcomm, noma ku-chipset eyayinikezwe ilayisense yi-Qualcomm.Le mali yelayisense isho ukuthi kunezindleko ezengeziwe zokuphatha ubuchwepheshe bokushaja ngokushesha, ngaphezu kwezindleko zehadiwe.
Ngakolunye uhlangothi, i-QC 3.0 inikeza izinzuzo ezimbalwa ezinkulu i-PD engazitholi.Okokuqala, izofinyelela ngokuzenzakalelayo kufika kuma-watts angu-36 uma itholwa ngezidingo ezifanayo.Njenge-PD, umkhawulo wamanzi wanoma iyiphi imbobo ye-USB ungahluka, kodwa umkhawulo ophansi ongakhona ungama-watts angu-15.Kodwa-ke, ukushaja kwe-PD kwehliswa kusuka ku-voltage eyodwa kuya kwenye.Isebenza ngama-wattages amisiwe, hhayi phakathi.Ngakho-ke, uma ishaja yakho ye-PD ingasebenza kuma-watts angu-15 noma angu-27, futhi uxhume ifoni yama-watt angu-20, izoshaja ngo-15 watts.Kumashaja asekela i-QC 3.0, ngakolunye uhlangothi, ahlinzeka nge-voltage eguquguqukayo ukuze anikeze umkhawulo wokushaja watt.Ngakho-ke uma unefoni eyindida eshaja ngo-22.5 watts, izothola ama-watts angu-22.5 ncamashi.
Enye inzuzo ye-QC 3.0 ukuthi ayidali ukushisa okuningi njengoba ikwazi ukulungisa i-voltage kancane isuka phansi iye phezulu esikhundleni sokugxuma isuka kwenye iye kwenye.Obunye ubuchwepheshe bokushaja okusheshayo bungaletha amandla amanje ngokweqile.Njengoba lokhu kwamanje kuhlangabezana nokumelana okunzima ngaphakathi kwedivayisi, kudala ukushisa okukhulu kakhulu.Ngenxa yokuthi i-QC iletha i-voltage okuyiyonayona edingekayo, asikho isikhathi eseqile sokudala ukushisa.
Ukuphepha
Amashaja e-USB ngokuvamile ahlinzeka ngezitifiketi ezihlukahlukene zokuphepha ezihlanganisa ukushajwa ngokweqile, i-overcurrent, ukushisa ngokweqile kanye nokuvikela ukujikeleza okufushane.Iziteshi zamandla ezinobuchwepheshe bokushaja okusheshayo, ngakolunye uhlangothi, ziphephe kakhulu njengoba ziqinisekisiwe nge-UL.I-UL iwumshwalense wokuphepha ophakeme kakhulu ohlinzeka ngezitifiketi zamasistimu kagesi emhlabeni wonke.Kuphephe kakhulu uma usebenzisa i-USB esohlwini lwe-UL ukuze uyisebenzisele ukuhlala noma ukuthengisa.
