Charger ilibe mizati yabwino komanso yoyipa? Choonadi chikuwululidwa

Kodi charger ili ndi ma pole abwino kapena oyipa?
Yankho ndilakuti: zimatengera mtundu wa charger.

1. Chaja yachikale ya DC (monga -chaja chapakamwa):

Chaja chamtunduwu nthawi zambiri chimakhala ndi mitengo yabwino komanso yoyipa. Mwachitsanzo, mkati mwa chaja yakale ya foni yam'manja ndi positive (+) ndipo mphete yakunja ndi yolakwika (-). Ngati chalumikizidwa molakwika, chikhoza kuwononga chipangizocho.

2. Chojambulira cha USB (monga USB-A/USB-C):

Mawonekedwe amakono a USB amazindikira mwanzeru polarity kudzera pama protocol, osasiyanitsa pakati pa mitengo yabwino ndi yoyipa. Kutengera USB-C monga chitsanzo, ma pin 24 ake amathandizira magetsi olowera pawiri ndipo amatha kugwira ntchito moyenera ngakhale atalumikizidwa molakwika (onaninso USB-IF standard).

3. Chaja opanda zingwe:

Sali-ku polar, kudalira ma elekitiromagineti kutumiza mphamvu, koma malo a koyilo akuyenera kulumikizidwa.

 

Chifukwa chiyani ma charger ena safunikira kusiyanitsa pakati pa mitengo yabwino ndi yoyipa?

1. Kuwongolera chip mwanzeru:

Mwachitsanzo, chipangizo cha PD chojambulira mwachangu chimangosintha komwe kulipo kuti mupewe zolakwika za polarity (mwachitsanzo, iPhone 12 ndi mitundu yapamwamba imathandizira 20W PD kuthamangitsa mwachangu).

2. Kapangidwe ka thupi:

USB-Mawonekedwe a C amatengera kamangidwe kofanana, ndipo zolumikizira za pulagi yakutsogolo ndi yakumbuyo ndizofanana. Malinga ndi data ya European Commission mu 2022, zida za USB-C zimachepetsa zinyalala zamagetsi ndi matani 11,000/chaka chifukwa chogwirizana.

 

Kusamvetsetsana kofala kwa ogwiritsa ntchito ndi malangizo otetezeka

1. Kusamvetsetsana:

- "Machaja onse atha kusakanikirana" → Kusagwirizana kwa Voltage/protocol kutha kuwononga batire (monga 9V yochapira mwachangu ndi chipangizo cha 5V).

- "Kutha kwa mawaya opanda zingwe ndikochepa" → Kutha kwaposachedwa kwa Qi2 ndikoposa 80% (poyerekeza ndi 90% ya mawaya).

2. Malangizo achitetezo:

- Gwiritsani ntchito ma charger oyambira kapena ovomerezeka (monga chiphaso cha MFi).

- Pewani kugwiritsa ntchito mawaya owonongeka kuti mupewe njira zazifupi.

Chidule cha nkhaniyi: Polarity ya charger imasintha chifukwa chaukadaulo. Posankha, muyenera kulabadira mawonekedwe mawonekedwe ndi ngakhale chipangizo kulipiritsa efficiently ndi mosamala.
