Uninzi lwezixhobo zakho ngoku zitshaja ngeezibuko ze-USB ngaphandle kwezixhobo zokutshaja ezingenazingcingo, kuba ukutshaja kwe-USB kuye kwayiguqula indlela esicinga ngayo ngamandla, kwaye kwenza kube lula ukubiza izixhobo ezahlukeneyo.Kulula kakhulu xa ilaptop yakho, ithebhulethi okanye i-smartphone isabelana ngombane ofanayo, konke okudingayo sisokethi se-USB esine-multiport kunye neentambo ezininzi ze-USB ezihambelanayo zokuqhagamshela.Ngamanye amaxesha usafuna enye iadaptha ye-AC ye-USB xa izibuko lakho lokutshaja lingahambelani namazibuko e-USB.Ngokokwazi kwethu, izixhobo zombane eziphathwayo ziyafumaneka ngoku ukutshaja ngaxeshanye ngenxa yokuba iadaptha eludongeni, iitshaja zeemoto, iitshaja zedesktop neebhanki zamandla ngoku ziyawuxhasa lo msebenzi.Ngaba sinokuqonda lo msebenzi xa kuziwa kwizixhobo zombane?Masihambe sixoxe ngento esiyifumana emarikeni.
Iindaba ezimnandi zezokuba iindawo ezininzi zombane ngoku ziyafumaneka ngezibuko ze-USB ezakhelwe kuzo.Iivenkile ze-USB bezikwimarike yokutshaja izixhobo zombane iminyaka elishumi.Siyabulela kwi-teknoloji ye-USB ekhula ngokukhawuleza, iteknoloji yokutshaja ngokukhawuleza ngoku isetyenziselwa ukutshaja, ngakumbi i-QC 3.0 kunye ne-PD iteknoloji, isinike isantya esimangalisayo.Ukuba usatshaja kwizibuko elidala le-USB le-A, awufumani esona santya siphezulu sokutshaja kwizixhobo zakho ezitsha.
Ungayikhetha njani i-USB Wall Outlet
Kulula kakhulu ukukhetha i-outlet yodonga lwe-USB kule mihla.Akunyanzelekanga ukuba ube ligcisa lombane xa ufuna ukuthenga i-USB eludongeni.Oku akuthethi ukuba ufanele ungakhathali.Nceda ujonge izixhobo zakho zombane kwaye ubone ngokucacileyo itekhnoloji yokutshaja ezihambelana nayo phambi kokuba uthenge.
Ukunikezelwa kwamandla e-USB (i-USB PD) vs. QC 3.0 Ukutshaja
Ngokwenyani, uninzi lwabathengi alucacanga kangako malunga nomahluko phakathi kwe-USB Power Delivery (PD) kunye ne-QC (i-Quick Charge) yokutshaja i-3.0.Ezi zombini zitekhnoloji zokutshaja ngokukhawuleza ngezibuko le-USB elisebenza ngokukhawuleza kune-USB eqhelekileyo.Zonke izixhobo zePD zinokuhlawuliswa kuphela ngezibuko le-USB-C™ ngelixa izixhobo zokutshaja ze-QC zinokuhlawuliswa nge-USB-A kunye ne-USB-C izibuko.Ngamanye amagama, kufuneka wazi ukuba loluphi uhlobo lwamandla oluthathwa sisixhobo sakho ngaphambi kokuba uthenge i-USB.Oko kwathiwa, ezinye izixhobo zixhasa iteknoloji yokutshaja iPD kunye neQC.Kwimeko enjalo, kufuneka ufumanise ukuba yeyiphi engcono.
Izibuko le-USB eliqhelekileyo alinakho ukuhambisa amandla angaphezu kwe-10 watts.UNikezelo lwaMandla oMbane we-USB izixhobo ezineprothokholi yokutshaja enokunikezela ukuya kuthi ga kwi-100 watts(20V/5A), oku kudla ngokufunwa yilaptop exhasa i-USB PD.Ngaphandle koko, ubuchwepheshe be-USB PD bukwaxhasa iiwathi zokutshaja ezahlukeneyo ezifana ne-5V/3A, 9V/3A, 12V/3A, 15V/3A kunye ne20V/3A.Kwi-smartphone okanye ithebhulethi, yonke imfuno yamandla iya kuba kwi-12V ephezulu.
Itekhnoloji yePD yaphuhliswa yi-USB Implementers Forum.Ukutshaja kwePD kunokufumaneka kuphela xa izixhobo zakho zombane, intambo ye-USB kunye nomthombo wamandla zonke zixhasa le teknoloji.Umzekelo, i-smartphone ayizukufumana ukutshaja kwePD xa i-smartphone yakho kunye neadaptha yamandla ixhasa iPD kodwa intambo yakho ye-USB-C ayiyixhasi.
I-QC ithetha iCharge eKhawulezayo eyaphuhliswa yiQualcomm kuqala.Oko kukuthi, i-QC isebenza kuphela ukuba isixhobo sisebenza kwi-chipset ye-Qualcomm, okanye kwi-chipset eyayinelayisensi yi-Qualcomm.Lo mrhumo welayisenisi uthetha ukuba kukho indleko eyongezelelweyo yokuthwala itekhnoloji yokutshaja ngokukhawuleza, ngaphaya kweendleko zehardware.
Kwelinye icala, i-QC 3.0 ibonelela ngeengenelo ezimbalwa ezinkulu ezingenazo iPD.Okokuqala, iya kufikelela ngokuzenzekelayo ukuya kuthi ga kwi-36 watts xa ifunyenwe kwiimfuno ezifanayo.NjengePD, obona buninzi bamanzi balo naliphi na izibuko le-USB linokwahluka, kodwa obona buninzi busezantsi bunokuba ngama-watts ali-15.Nangona kunjalo, ukutshaja kwePD kunyuswa ukusuka kwenye ivolthi ukuya kwenye.Isebenza kwi-wattages emiselweyo, hayi phakathi.Ke, ukuba itshaja yakho yePD inokusebenza kwi-watts ezili-15 okanye ezingama-27, kwaye uplagi kwifowuni ye-20-watt, iya kuhlawulisa nge-15 watts.Kwiitshaja ezixhasa i-QC 3.0, kwelinye icala, zibonelela ngombane oguquguqukayo ukunika i-watt yokutshaja ephezulu.Ke ukuba unefowuni enqabileyo ebiza i-22.5 watts, iya kufumana kanye i-22.5 watts.
Enye inzuzo ye-QC 3.0 kukuba ayenzi bushushu obuninzi njengoko ikwazi ukulungelelanisa i-voltage kancinane ukusuka ezantsi ukuya phezulu endaweni yokutsiba ukusuka kwenye ukuya kwenye.Obunye ubuchwephesha bokutshaja ngokukhawuleza bunokuzisa ugqithiso lwangoku.Kuba le yangoku idibana nochaso olunzima ngaphakathi kwesixhobo, yenza ubushushu obuninzi kakhulu.Ngenxa yokuba i-QC ihambisa amandla ombane afunekayo, akukho mbane ugqithileyo wokudala ubushushu.
Ukhuseleko
Iitshaja ze-USB zihlala zibonelela ngezatifikethi ezahlukeneyo zokhuseleko ezibandakanya ukutshaja ngaphezulu, i-overcurrent, ubushushu obugqithisileyo kunye nokhuseleko olufutshane.Izixhobo zombane ezinetekhnoloji yokutshaja ngokukhawuleza, kwelinye icala, zikhuselekile njengoko ziqinisekisiwe nge-UL.I-UL yeyona inshurensi yokhuseleko iphezulu ebonelela ngeziqinisekiso zeenkqubo zombane kwihlabathi liphela.Kukhuseleke kakhulu xa usebenzisa i-USB edweliswe kwi-UL yosetyenziso lwendawo yokuhlala okanye yorhwebo.
