Bhatiri Rakanakisisa reBanki reMagetsi
Munguva iyo mafoni, maTWS, mawachi emagetsi, uye kunyange makamera ekuita zvinhu zvave chikamu chehupenyu hwezuva nezuva, mabhangi emagetsi haasisiri chinhu chinobatsira chete—asi anoponesa kana pasina nzira yekubuda nayo magetsi. Zvisinei, pakusarudza bhangi remagetsi, vanhu vazhinji vanobatwa nenhamba inonyanya kuzivikanwa papakeji: mAh (milliampere-awa). Zvisinei, "kukwanisa kwepamusoro" hazvirevi nguva dzose kuti "zvakanakisa." Chinyorwa chino chinoongorora mabhatiri akanakisa emagetsi emagetsi, kusanganisira maitiro ekuongorora kugona kwemagetsi, mhando dzemasero emabhatiri, uye mazano esimba zvichienderana nezvinodiwa pakushandisa.
Kunzwisisa Kugona: mAh vs Wh
Kugona kwebhengi remagetsi kunowanzo nyorwa mu mAh, semuenzaniso, 10.000 mAh kana 20.000 mAh. Nhamba iyi inowanzo reva kugona kwemaseru ebhatiri remukati pavoltage ye3,7V (mabhatiri e lithium). Mudziyo uri kuchajwa unowanzo gamuchira simba kuburikidza neUSB pa5V (kana kupfuura kuti uchajike nekukurumidza, senge 9V/12V).
Kuyera simba kwakanyatsojeka ndiWh (Watt-awa), nekuti kunotora voltage. Fomura iri nyore ndeiyi:
Wh = (mAh × V) / 1000
Semuenzaniso, bhangi remagetsi re10.000 mAh pa3,7V:
– Wh = (10.000 × 3,7) / 1000 = Wh 37
Kana bhengi remagetsi richichinja 3,7V kuita 5V (kana kupfuura), pane kurasikirwa nekuchinja uye kurasikirwa nekupisa, zvichikonzera kuti simba risingashande zvakanaka risvike pafoni. Kazhinji, kushanda zvakanaka kuri pakati pe70%–90%, zvichienderana nemhando yecircuit uye nzira yekuchaja.
Kugona "Kwechokwadi" Kunoshandiswa
Heino chikonzero nei bhangi remagetsi re10.000 mAh risingareve kuti unogona kuchaja foni ye5.000 mAh kaviri. Pane zvikonzero zvakati wandei:
1. Kushandurwa kweVoltage (3,7V kuenda ku5V/9V)
2. Kupisa uye kushanda zvakanaka kwedunhu
3. Tambo nezvinongedzo (kana tambo yacho yakashata, simba rayo rinorasikirwa zvakanyanya)
4. Kuchaja bhatiri refoni hakushande zvizere.
Kuti tinzwisise izvi, bhangi remagetsi remhando yepamusoro re10.000 mAh rinowanzo kwanisa kushanda zvakanaka kubva pa6.500–8.500 mAh pa5V. Bhengi remagetsi re20.000 mAh rinowanzo kwanisa kushanda zvakanaka kubva pa13.000–17.000 mAh.
Saka, patinotaura nezve "kugona kwakanyanya," chatiri kutsvaga hachisi nhamba huru chete, asi kugona kunoenzanisa saizi, huremu, kuchengetedzeka, kutenderera kwehupenyu, uye kukodzera zvaunoda.
Mhando dzeMabhatiri eMagetsi: Li-ion vs Li-Po
Kugona kwakanyanya kunokonzerwawo nerudzi rwesero rebhatiri rinoshandiswa.
1) Lithium-ion (Li-ion)
Kazhinji shandisa masero e cylindrical (semuenzaniso 18650 kana 21700).
Zvakawandisa:
- Kazhinji zvakachipa
- Kukwanisa kukuru kunowanikwa zvakanyanya
– Inogara kwenguva refu kana mhando yemasero yakanaka
Kekurangan:
- Chimiro chesilinda chinoita kuti dhizaini yebhangi remagetsi ive gobvu
– Zvinoenderana nemhando yemasero; zvigadzirwa zvakachipa zvinogona kushandisa masero akadzokororwa.
2) Lithium-polymer (Li-Po)
Kazhinji inenge iri muchimiro chebhegi (rakatsetseka) uye inozivikanwa mumabhanga emagetsi madiki.
Zvakawandisa:
- Dhizaini yacho yakatetepa uye inochinjika zviri nyore
- Huremu hunogona kureruka nekuda kwesimba rakafanana
- Inowanzoonekwa seyakachengeteka mune mamwe magadzirirwo (zvichienderana nedziviriro)
Kekurangan:
- Kazhinji zvinodhura zvakanyanya
– Kana hunhu hwacho husina kunaka, hunogona kuzvimba.
Ose anogona kuva "akanakisisa", chero bedzi achishandisa masero emhando yepamusoro uye aine dziviriro yakakwana (yakawandisa, yakawandisa, yakawandisa, short-circuit, uye dziviriro yekupisa).
Kugona Kwakanakisisa Kwakavakirwa Pazvinodiwa
Haasi munhu wese anoda 30.000 mAh. Kusarudza "yakanakisa" kunoenderana nemamiriro ekushandisa.
1) 5.000–10.000 mAh: Yakanakira Mwenje Zuva Nezuva
Uku ndiko kugona kwakakodzera kwe:
- Vashandisi vanowanzova muhofisi/kambasi
- Unoda backup yekuchaja kamwe chete pafoni
- Chinonyanya kukosha pane saizi diki uye huremu hwakareruka
Bhangi remagetsi re10.000 mAh inzvimbo inozivikanwa zvikuru: inokwana mamiriro mazhinji, iri nyore kutakura, uye inowanzo kurumidza kuchaja.
2) 10.000–20.000 mAh: Yakanakira Kufamba Kwakanyanya
Jika Anda:
- Kazhinji kufamba zuva rese
- Vimba neGPS, kamera, nzvimbo yekuona nzvimbo
- Takura zvishandiso zvinopfuura chimwe chete (foni + TWS + smartwatch)
Saka bhatiri re20.000 mAh rinowanzova sarudzo yakanakisisa. Kugona uku kunogona kuchaja foni ine 4.500–5.000 mAh kanenge kaviri kusvika katatu (zvichienderana nekushanda kwayo uye chaji yasara).
3) 20.000–30.000 mAh: Yakanakira mafambiro marefu kana michina yakawanda
Kugona uku kwakakodzera:
– Vafambi vanonetseka kuwana nzvimbo yemagetsi
- Vashandisi vane tablet
- Mabasa ekunze (kukamba, kufukidza, zviitiko)
Zvisinei, funga nezvehuremu nenguva yekuchaja. Mabhangi makuru emagetsi asina zvinhu zvinopinda zvekuchaja nekukurumidza zvinogona kutora nguva yakareba kuti achajirwe.
4) Pamusoro pe30.000 mAh: Yakakosha, Kwete Yemunhu Wese
Kukwanisa kukuru kwakakodzera kana:
– Unoda simba rekushandisa laptop yako (USB-C PD ine simba rakawanda)
- Inodiwa senzvimbo yemagetsi madiki
Asi:
- Yakakura uye yakakura
- Hazviwanzoshanda pamabhegi madiki
- Iva nechokwadi chekuti inoenderana nemiganhu yekubhururuka (kazhinji kambani dzendege dzinoganhurira mabhatiri kusvika pa100Wh yekabhini pasina mvumo yakakosha; mamwe anobvumidza kusvika ku160Wh kana abvumidzwa)
Kukwanisa Kukuru Kunofanira Kuenzaniswa Nekubuda Nekupinda
Bhangi remagetsi "rakanakisisa" richava rinosuwisa kana:
– Inoburitsa 5V 1A chete (inochaja zvishoma nezvishoma)
– Haitsigire kuchaja nekukurumidza (PD/QC)
- Kuisa mari zvishoma nezvishoma (zvinotora maawa akawanda)
Kuti uwane ruzivo rwakanakisisa, tsvaga:
- USB-C Power Delivery (PD) yemidziyo yemazuva ano
– Kubuda kushoma 18W (zviri nani 20W/30W/45W zvichienderana nezvinodiwa)
- USB-C input inotsigirawo kuchaja nekukurumidza kuitira kuti power bank ikwanise kuchajwa nekukurumidza
Simba re20.000 mAh rine 20W USB-C PD rinowanzoonekwa semusanganiswa wesimba, kumhanya, uye kutakura zvinhu zviri nyore.
Hunhu hwePower Bank ine "Kugona Kwakanakisisa" (Kwete Kungova Yakakura)
Pakusarudza, teerera kune:
1. Kugona kwakataurwa ndekwechokwadi uye kune "kugona kwakayerwa" (kugona kwakayerwa pa5V output).
2. Chitupa chekuchengetedza (semuenzaniso CE, FCC, RoHS, kana zviyero zvemuno; mukurumbira wemugadziri uye maitiro ekudzivirira zvakakosha).
3. Hunhu hwesero (mabrandi anovimbwa anowanzo enderana).
4. Dziviriro yekupisa nemagetsi kuitira kuchengetedza nharembozha nebhangi remagetsi pacharo.
5. Waranti uye sevhisi yekutengeswa mushure mekutengesa — kunyanya kune vanhu vane simba guru.
Mhedziso: Kugona Kwakanakisisa Ndiko Kwakakodzera
Kana waifanira kusarudza simba rimwe chete rinokodzera vanhu vazhinji, simba remagetsi rinobva pa10.000–20.000 mAh ndiro rakanakisa. Kune vashandisi vemazuva ese vanokoshesa simba remagetsi, 10.000 mAh ndiyo yakakodzera. Pakushandisa michina yakawanda uye midziyo yakawanda, 20.000 mAh ndiyo iri nani. Kupfuura izvozvo, simba guru rinouya nekuwedzera kwekuchinjana: huremu, saizi, uye nguva yekuchaja.
Pakupedzisira, bhengi remagetsi rakanakisa harisi iro rine nhamba dzepamusoro, asi iro rinonyatsokodzera purogiramu yako—rine kugona kushanda, rutsigiro rwekuchaja nekukurumidza, uye maficha akajeka ekuchengetedza.
Kana muchida, ndinogona kukubatsirai kuti muwane simba remagetsi rakakwana uye zvinodiwa zvichienderana nerudzi rwefoni yenyu, zvinodiwa pakuchaja zuva nezuva, uye kana muchida tablet kana laptop.
