Feem ntau ntawm koj cov khoom tam sim no tau them los ntawm USB chaw nres nkoj tshwj tsis yog cov khoom siv wireless charging, vim tias USB them nyiaj tau hloov pauv txoj kev peb xav txog lub zog, thiab ua kom yooj yim them ntau yam khoom siv.Nws yog qhov yooj yim heev thaum koj lub laptop, ntsiav tshuaj lossis smartphone sib koom tib lub zog, txhua yam koj xav tau tsuas yog ib lub qhov (socket) multiport USB thiab ob peb txuas USB cables rau kev sib txuas.Qee lub sij hawm koj tseem xav tau ib qho ntxiv USB AC adapter thaum koj qhov chaw nres nkoj them tsis haum rau USB chaw nres nkoj.Raws li peb paub, cov khoom siv hluav taws xob txawb tau tam sim no muaj rau kev them nyiaj ib txhij vim tias phab ntsa adapters, lub tsheb chargers, desktop chargers txawm tias lub tsev txhab nyiaj fais fab tam sim no txhawb qhov kev ua haujlwm no.Peb puas tuaj yeem paub qhov haujlwm no thaum nws los txog rau cov khoom siv hluav taws xob?Cia peb mus tham txog yam peb nrhiav tau los ntawm kev ua lag luam.
Cov xov xwm zoo yog tias tam sim no muaj ntau lub qhov hluav taws xob muaj nrog USB chaw nres nkoj ua rau lawv.USB qhov hluav taws xob tau nyob hauv kev ua lag luam rau kev them nyiaj hluav taws xob rau ib xyoo caum.Ua tsaug rau cov cuab yeej siv USB nrawm nrawm, cov thev naus laus zis thev naus laus zis tam sim no tau siv dav rau kev them nyiaj, tshwj xeeb tshaj yog rau QC 3.0 thiab PD thev naus laus zis, tau muab peb cov kev ceev nrawm.Yog tias koj tseem them nyiaj rau ntawm qhov qub USB Hom-A chaw nres nkoj, koj tsis tau txais qhov ceev tshaj plaws them nqi rau koj cov khoom siv tshiab.
Yuav ua li cas xaiv lub qhov hluav taws xob USB phab ntsa
Nws yog qhov yooj yim heev rau xaiv lub qhov hluav taws xob USB phab ntsa niaj hnub no.Koj tsis tas yuav yog tus kws tshaj lij hluav taws xob thaum koj xav yuav lub qhov hluav taws xob USB phab ntsa.Qhov no tsis tau txhais hais tias koj yuav tsum tsis saib xyuas.Thov xyuas koj cov khoom siv hluav taws xob thiab saib kom meej tias cov thev naus laus zis thev naus laus zis uas lawv tau sib haum nrog ua ntej koj yuav khoom.
USB Power Delivery (USB PD) vs. QC 3.0 Them
Qhov tseeb, cov neeg siv khoom feem ntau tsis meej meej txog qhov sib txawv ntawm USB Power Delivery (PD) thiab QC (Quick Charge) 3.0 them.Cov no yog ob qho tib si ceev them thev naus laus zis ntawm USB chaw nres nkoj uas ua haujlwm sai dua li USB zoo tib yam.Tag nrho cov khoom siv PD tuaj yeem raug them los ntawm USB-C ™ chaw nres nkoj thaum QC them cov khoom siv tuaj yeem them ntawm ob qho tib si USB-A thiab USB-C chaw nres nkoj.Hauv lwm lo lus, koj yuav tsum paub seb hom fais fab twg koj lub cuab yeej siv ua ntej koj yuav lub qhov hluav taws xob USB.Hais tias, qee cov khoom siv tau txhawb nqa ob qho tib si PD thiab QC them thev naus laus zis.Nyob rau hauv tas li ntawd, koj yuav tsum paub seb qhov twg yog qhov zoo dua.
Ib qho yooj yim USB chaw nres nkoj tuaj yeem xa tsis pub ntau tshaj 10 watts ntawm lub zog.USB Power Delivery enabled pab kiag li lawm nrog them raws tu qauv uas muaj peev xwm xa mus txog 100 watts (20V / 5A), qhov no feem ntau yuav tsum tau los ntawm lub laptop uas txhawb USB PD.Tsis tas li ntawd, USB PD thev naus laus zis kuj txhawb kev them nyiaj sib txawv xws li 5V / 3A, 9V / 3A, 12V / 3A, 15V / 3A thiab 20V / 3A.Rau lub xov tooj smartphone lossis ntsiav tshuaj, txhua lub zog xav tau yuav yog 12V siab tshaj plaws.
PD thev naus laus zis tau tsim los ntawm USB Implementers Forum.Lub PD them nyiaj tuaj yeem muaj tsuas yog thaum koj cov khoom siv hluav taws xob, USB cable thiab lub zog hluav taws xob tau txhawb nqa cov thev naus laus zis no.Piv txwv li, lub smartphone yuav tsis tau txais PD them thaum koj lub xov tooj smartphone thiab lub hwj chim adapter txhawb nqa PD tab sis koj lub USB-C cable tsis txhawb nqa nws.
QC txhais tau tias Quick Charge uas tau tsim los ntawm Qualcomm thawj zaug.Qhov ntawd yog hais tias, QC tsuas yog ua haujlwm yog tias lub cuab yeej khiav ntawm Qualcomm chipset, lossis ntawm lub chipset uas tau ntawv tso cai los ntawm Qualcomm.Cov nqi ntawv tso cai no txhais tau hais tias muaj tus nqi ntxiv rau kev nqa cov thev naus laus zis thev naus laus zis, dhau ntawm tus nqi kho vajtse.
Ntawm qhov tod tes, QC 3.0 muaj ob peb qhov txiaj ntsig loj uas PD tsis ua.Ua ntej, nws yuav cia li ncav cuag li 36 watts thaum nws tau kuaj pom cov kev cai tib yam.Zoo li PD, qhov siab tshaj plaws wattage ntawm ib qho chaw nres nkoj USB tuaj yeem sib txawv, tab sis qhov qis tshaj qhov siab tshaj plaws yog 15 watts.Txawm li cas los xij, PD charging yog nce los ntawm ib qho hluav taws xob mus rau lwm qhov.Nws ua haujlwm ntawm teeb wattages, tsis nyob rau hauv-nruab nrab.Yog li, yog tias koj lub charger PD tuaj yeem ua haujlwm ntawm 15 lossis 27 watts, thiab koj ntsaws lub xov tooj 20 watt, nws yuav them ntawm 15 watts.Rau cov chargers uas txhawb QC 3.0, ntawm qhov tod tes, muab qhov sib txawv voltage kom muab lub siab tshaj plaws them watt.Yog li yog tias koj muaj lub xov tooj quirky uas them ntawm 22.5 watts, nws yuav tau txais raws nraim 22.5 watts.
Lwm qhov zoo ntawm QC 3.0 yog tias nws tsis tsim kom muaj cua sov ntau vim nws tuaj yeem kho qhov voltage me ntsis los ntawm qis mus rau siab dua es tsis txhob dhia ntawm ib qho mus rau lwm qhov.Qee lwm cov thev naus laus zis ceev tuaj yeem xa tawm tam sim no.Txij li qhov tam sim no ua tau raws li qhov hnyav hauv lub cuab yeej, nws tsim kom muaj cua sov ntau dhau.Vim tias QC xa cov hluav taws xob tiag tiag, tsis muaj qhov tam sim no dhau los ua kom sov.
Kev nyab xeeb
USB chargers feem ntau muab ntau yam ntawv pov thawj kev nyab xeeb xws li overcharge, overcurrent, overheating thiab short-circuiting tiv thaiv.Cov hluav taws xob hluav taws xob nrog cov thev naus laus zis thev naus laus zis, ntawm qhov tod tes, muaj kev nyab xeeb heev vim nws tau ntawv pov thawj UL.UL yog daim ntawv pov hwm kev nyab xeeb siab tshaj plaws uas muab ntawv pov thawj rau cov tshuab hluav taws xob thoob ntiaj teb.Nws muaj kev nyab xeeb heev thaum koj siv UL teev USB qhov hluav taws xob rau kev siv vaj tse lossis kev lag luam.
