Nyob rau hauv niaj hnub tech-tsav ntiaj teb no, chargers yog ib qho tseem ceeb rau powering peb li, los ntawm smartphones mus rau laptops. Txawm li cas los xij, tsis yog txhua lub chargers raug tsim sib npaug. Qee qhov ua haujlwm ntawm kev hloov tam sim no (AC), thaum lwm tus siv tam sim no (DC). Nkag siab qhov sib txawv ntawm AC thiab DC chargers yog qhov tseem ceeb rau kev ua kom muaj kev sib raug zoo nrog koj cov khoom siv thiab tiv thaiv kev puas tsuaj. Cov lus qhia no yog tsim los rau txhua tus neeg uas xav kawm paub seb lawv lub charger yog AC lossis DC, muab cov lus qhia ua ntu zus thiab cov lus qhia muaj txiaj ntsig ntawm txoj kev.
Nkag siab txog AC thiab DC
Ua ntej dhia mus rau hauv kev txheeb xyuas, nws tseem ceeb heev kom nkag siab tias AC thiab DC txhais li cas. **Alternating Current (AC)** yog hom hluav taws xob uas los ntawm koj lub qhov hluav taws xob phab ntsa. Nws hloov pauv cov kev taw qhia ib ntus, uas ua rau nws haum rau kev sib kis mus ntev. ** Direct Current (DC)**, ntawm qhov tod tes, ntws hauv ib qho kev taw qhia thiab feem ntau yog siv los ntawm cov roj teeb thiab cov khoom siv hluav taws xob. Chargers hloov AC los ntawm koj lub qhov hluav taws xob phab ntsa rau hauv DC, uas yog yam khoom siv feem ntau xav tau.
Yuav Qhia Li Cas Koj Hom Charger
Xyuas daim ntawv lo
Qhov yooj yim tshaj plaws los txiav txim seb koj lub charger yog AC lossis DC yog los xyuas daim ntawv lo. Feem ntau cov chargers muaj daim ntawv lo los yog luam ntawv uas muab cov ntaub ntawv tseem ceeb. Nrhiav cov ntsiab lus xws li 'Input' thiab 'Output.' Yog hais tias cov zis hais txog DC, xws li 'Output: 5V DC,' ces nws yog DC charger. Hloov pauv, yog tias nws hais txog AC, nws yog AC charger.
Tshawb xyuas hom Plug
Lwm txoj hauv kev los txheeb xyuas hom charger yog los ntawm kev tshuaj xyuas lub ntsaws. AC chargers feem ntau muaj ob lossis peb lub ntsaws ntsaws uas haum rau hauv lub qhov (socket) phab ntsa. DC chargers feem ntau muaj lub cylindrical plug uas txuas mus rau lub cuab yeej ncaj qha, xws li lub laptop lossis lub koob yees duab.
Siv lub Multimeter
Yog tias koj tseem tsis paub meej, siv multimeter tuaj yeem muab cov lus teb meej. Teem lub multimeter los ntsuas qhov voltage, tom qab ntawd txuas mus rau lub charger cov zis terminals. Yog tias kev nyeem ntawv ruaj khov thiab tsis hloov pauv, nws yog DC charger. Yog tias qhov kev nyeem ntawv hloov pauv, nws yog AC charger.
Nrog rau tus neeg siv phau ntawv
Yog tias koj muaj kev nkag mus rau cov neeg siv phau ntawv, nws yuav tsum qhia meej hom charger xav tau rau koj lub cuab yeej. Qhov no tuaj yeem yog qhov kev ntseeg siab ntawm cov ntaub ntawv yog tias daim ntawv lo tau hnav lossis tsis meej.
Lus Qhia thiab Lus Ceeb Toom
Nco ntsoov xyuas kom meej tias qhov ntsuas hluav taws xob thiab qhov ntsuas tam sim no ntawm lub charger phim koj cov khoom siv kom tsis txhob muaj kev puas tsuaj.
Ceev faj thaum siv cov khoom siv thib peb, vim lawv yuav tsis ua raws li cov qauv qub raws li cov khoom siv thawj zaug (OEM) chargers.
Yog tias koj tsis paub meej txog lub charger cov lus qhia tshwj xeeb, nrog tus kws tshaj lij kom tsis txhob muaj kev phom sij.
Xaus
Kev txheeb xyuas seb koj lub charger yog AC lossis DC yog txheej txheem ncaj qha uas tuaj yeem cawm koj ntawm cov khoom siv puas tsuaj. Los ntawm kev txheeb xyuas daim ntawv lo, tshuaj xyuas cov ntsaws hom, siv lub tshuab multimeter, lossis sab laj tus neeg siv phau ntawv, koj tuaj yeem yooj yim txiav txim siab lub charger hom. Nco ntsoov ib txwm siv cov chargers uas phim koj lub cuab yeej tshwj xeeb thiab sab laj cov kws tshaj lij yog tias koj tsis paub meej. Nrog rau qhov kev paub no, koj tuaj yeem ua kom koj cov khoom siv tau them nyiaj nyab xeeb thiab ua tau zoo.
