Pūhiko Kaha Pai rawa atu mō te Pēke Hiko
I tēnei wā kua noho ngā waea atamai, ngā TWS, ngā mataaratanga atamai, tae atu ki ngā kāmera mahi hei wāhanga o te oranga o ia rā, ehara i te mea he taputapu noa iho ngā pēke hiko—he mea āwhina ina kore he putanga hiko. Heoi, i te wā e whiriwhiri ana i tētahi pēke hiko, he maha ngā tāngata ka mau ki te tau kotahi e kitea nuitia ana i runga i te takai: mAh (milliampere-haora). Heoi, kāore te "kaha nui" i te tikanga "pai rawa atu". Ka tūhuratia e tēnei tuhinga ngā pākahiko kaha pai rawa atu mō ngā pēke hiko, tae atu ki te aromatawai i te kaha tūturu, ngā momo pūtau pākahiko, me ngā taunakitanga kaha i runga i ngā hiahia whakamahinga.
Te Mārama ki te Pūngao: mAh me te Wh
Ko te kaha o te peeke hiko e whakarārangihia ana i roto i te mAh, hei tauira, 10.000 mAh, 20.000 mAh rānei. Ko tēnei tau e pā ana ki te kaha o ngā pūtau pākahiko o roto i te ngaohiko ingoa tata ki te 3,7V (ngā pākahiko lithium). Ko te taputapu e utua ana ka whiwhi hiko mā te USB i te 5V (neke atu rānei mō te utu tere, pērā i te 9V/12V).
Ko te ine pūngao tika ake ko te Wh (Watt-haora), nā te mea ka whakaarohia te ngaohiko. Ko te tātai māmā ko:
Wh = (mAh × V) / 1000
Hei tauira, he pēke hiko 10.000 mAh i te 3,7V:
– Wh = (10.000 × 3,7) / 1000 = 37 Wh
Ina tahuri te pēke hiko i te 3,7V ki te 5V (neke atu rānei), ka puta he ngaronga whakawhiti me te ngaronga wera, ka iti ake te kaha e tae atu ana ki te waea. I te nuinga o te wā, kei waenganui i te 70%–90% te pai o te mahi, i runga i te kounga o te ara iahiko me te kawa utu.
Te Pūmanawa Whakamahi "Tūturu"
Anei te take kāore e taea e te pēke hiko 10.000 mAh te utu katoa i te waea 5.000 mAh kia rua ngā wā. He maha ngā take:
1. Te tahuritanga ngaohiko (3,7V ki te 5V/9V)
2. Te wera me te whai huatanga o te ara iahiko
3. Ngā taura me ngā hononga (ka nui ake te ngaronga hiko mēnā he kino te kounga o te taura)
4. Kāore te utunga e 100% te whai hua mō te pākahiko o te waea.
Hei whakamārama i tēnei, ko te kaha hiko o tētahi pēke hiko kounga pai 10.000 mAh ka tata ki te 6.500–8.500 mAh i te 5V. Ko te kaha hiko o tētahi pēke hiko 20.000 mAh ka tata ki te 13.000–17.000 mAh.
Nō reira, ina kōrero tātou mō te "pūmanawa pai rawa atu," ehara i te mea he tau nui noa iho tā tātou e rapu nei, engari he pūmanawa e taurite ana i te rahi, te taumaha, te haumaru, te huringa ora, me te pai mō ō hiahia.
Ngā Momo Pūhiko mō ngā Pēke Hiko: Li-ion me Li-Po
Ka pāngia anō te kaha pai e te momo pūtau pākahiko e whakamahia ana.
1) Ritiumu-ion (Ritiumu-ion)
Ko ngā pūtau porotaka te nuinga o te wā e whakamahia ana (hei tauira, 18650, 21700 rānei).
Te taikaha:
– He iti ake te utu i te nuinga o te wā
– He nui te kaha e wātea ana
– Ka roa te mau mena he pai te kounga o te pūtau
Te korenga:
– Nā te āhua porotaka ka matotoru ake te hoahoa o te peeke hiko
– Kei te kounga o te pūtau; ko ngā hua iti ake te utu ka whakamahi pea i ngā pūtau hangarua.
2) Ritiuma-pūmua (Li-Po)
He pēke papatahi te āhua i te nuinga o te wā, ā, he rongonui i roto i ngā pēke hiko angiangi.
Te taikaha:
– He angiangi ake, he ngāwari ake te hoahoa
– Ka māmā ake te taumaha mō te kaha ōrite
– He maha ngā wā ka whakaarohia he haumaru ake i roto i ētahi hoahoa (i runga i te tiakitanga)
Te korenga:
– He nui ake te utu i te nuinga o te wā
– Ki te kore e pai te kounga, ka pupuhi pea.
Ka taea e ngā mea e rua te "pai rawa", mena he pūtau kounga teitei te whakamahi, ā, he tiaki katoa (te utu nui, te tukunga nui, te iahiko nui, te ara iahiko poto, me te tiaki wera).
Te Pūmanawa Pai rawa atu i runga i ngā Hiahia
Kāore e hiahiatia ana e te katoa te 30.000 mAh. Ko te whakatau i te "pai rawa" ka whakawhirinaki ki ngā āhuatanga whakamahinga.
1) 5.000–10.000 mAh: Pai rawa atu mō te Mārama o ia Rā
Koinei te kaha tino pai mō:
– Ngā kaiwhakamahi e noho pinepine ana i te tari/kāreti
– Me whai tārua o te utunga waea pūkoro kotahi
– Ko te rahi kiato me te taumaha mama te mea nui
He "wāhi pai" rongonui te pēke hiko 10.000 mAh: he nui mō te nuinga o ngā āhuatanga, he ngāwari ki te kawe, ā, he tere tonu te whakakī anō.
2) 10.000–20.000 mAh: Pai rawa atu mō te Nekenekehanga Nui
Mena koe:
– He maha ngā wā e haereere ana i te rā katoa
– Whakawhirinaki ki te GPS, kāmera, wāhi wera
– Kawe i ngā taputapu neke atu i te kotahi (waea + TWS + mātaaratanga atamai)
Nō reira, ko te pākahiko 20.000 mAh te kōwhiringa pai rawa atu. Ka taea e tēnei kaha te utu i tētahi waea 4.500–5.000 mAh kia 2–3 ngā wā (i runga i te pai o te mahi me te utunga e toe ana).
3) 20.000–30.000 mAh: Pai rawa atu mō ngā Haerenga Roa, mō ngā Pūrere Maha rānei
He pai tēnei kaha mō:
– Ngā tāngata haereere e uaua ana ki te kimi i tētahi putanga hiko
– Ngā kaiwhakamahi e mau ana i tētahi papahiko
– Ngā mahi o waho (te puni, te kapinga, ngā huihuinga)
Heoi, whakaarohia te taumaha me te wā utu. Ka roa pea te wā e utu ai ngā pūhiko nui kāore he urunga utu tere.
4) Neke atu i te 30.000 mAh: He mea motuhake, ehara i te mea mā te katoa
He pai te kaha nui mēnā:
– Me hiahia koe ki te hiko mō tō pona (PD USB-C teitei)
– E hiahiatia ana hei pūtake hiko iti
Engari:
– He taumaha ake, he matotoru ake
– Kāore i te whai hua i ngā wā katoa mō ngā putea iti
– Kia tino rite ki ngā herenga rere (ko te tikanga ka whakawhāitihia e ngā kamupene rererangi te pākahiko ki te 100Wh mō te kāpini me te kore whakaaetanga motuhake; ko ētahi ka whakaaetia kia tae ki te 160Wh me te whakaaetanga)
Me taurite te kaha nui ki te putanga me te whakaurunga
Ka pāpouri te pēke hiko "pai rawa" mēnā:
– Putanga anake 5V 1A (whakautu puhoi)
– Kāore e tautoko i te utu tere (PD/QC)
– Te puhoi o te whakaurunga utu (e maha ngā hāora e pau ana)
Mō te wheako pai rawa atu, rapua:
– Tukunga Mana USB-C (PD) mō ngā taputapu hou
– Putanga iti rawa 18W (pai ake 20W/30W/45W i runga i ngā hiahia)
– He urunga USB-C e tautoko ana hoki i te utu tere kia tere ai te utu i te pēke hiko
Ko te kaha 20.000 mAh me te 20W USB-C PD e kiia ana ko te huinga tino taurite o te mana, te tere, me te ngāwari ki te kawe.
Ngā Āhuatanga o te Pēke Mana me te Pūmanawa "Pai Rawa" (Ehara i te Mea Nui Noa)
I te wā e whiriwhiri ana, kia aro ki:
1. He mea tūturu te kaha kua whakahuatia, ā, he whakatakotoranga "kaha kua whakatauria" (kaha inehia i te putanga 5V).
2. Tiwhikete haumaru (hei tauira, CE, FCC, RoHS, ngā paerewa ā-rohe rānei; he mea nui te ingoa o te kaihanga me ngā āhuatanga tiaki).
3. Te kounga o te pūtau (he rite tonu te nuinga o ngā waitohu pono).
4. Te tiaki i te pāmahana me te au hiko hei whakarite i te haumaru o te waea pūkoro me te pēke hiko tonu.
5. Pūtāhui me te ratonga muri-hoko — inā koa mō ngā kaha nui.
Whakatau: Ko te Pūmanawa Pai rawa atu te mea tino tika
Mena me whiriwhiri koe i tētahi kaha kotahi e pai ana ki te nuinga o te tangata, ko te 10.000–20.000 mAh te whānuitanga kaha pai rawa atu o te pēke hiko. Mō ngā kaiwhakamahi o ia rā e aro nui ana ki te kiato, he pai te 10.000 mAh. Mō te nekeneke tere me te whakamahi i ngā taputapu maha, he pai ake te 20.000 mAh. Haunga tēnā, ka nui ake ngā painga o ngā kaha nui ake: te taumaha, te rahi, me te wā utu.
Hei whakamutunga, ehara te pēke hiko pai rawa atu i te mea he nui rawa ngā nama, engari ko te mea e tino pai ana mō tō mahinga o ia rā—me te kaha tino whai hua, te tautoko utu tere tika, me ngā āhuatanga haumaru mārama.
Ki te hiahia koe, ka taea e au te āwhina i a koe ki te taunaki i te kaha me ngā whakaritenga o te pēke hiko e tika ana mō te momo waea, ngā hiahia utu o ia rā, me te mea e hiahiatia ana mō te papahiko, mō te pona rānei.
