I te nuinga o te wā, he 3.7vpākahiko lithiumme whai "papa tiaki" mō te utu nui me te tukunga nui. Mena kāore he papa tiaki o te pākahiko, ka taea anake te whakamahi i te ngaohiko utu tata ki te 4.2v, nā te mea ko te ngaohiko utu katoa pai rawa atu o te pākahiko lithium ko te 4.2v, ā, neke atu i te 4.2v te ngaohiko. Mēnā ka pakaru te pākahiko, i te wā e utu ana i tēnei ara, me aroturuki tonu te āhua o te pākahiko.
Mena he papa tiaki, ka taea e koe te whakamahi i te 5v (ka taea te whakamahi i te 4.8 ki te 5.2), te USB5v o te rorohiko, te rihi hiko 5v rānei o te waea pūkoro.
Mō te pākahiko 3.7V, ko te ngaohiko tapahi utu ko 4.2V, ā, ko te ngaohiko tapahi tukunga ko 3.0V. Nō reira, ina iti iho te ngaohiko ara iahiko tuwhera o te pākahiko i te 3.6V, me taea te utu. He pai ake te whakamahi i te aratau utu ngaohiko pumau 4.2V, kia kore ai koe e aro ki te wā utu. He ngāwari te utu nui rawa atu ina utuhia me te 5V, ā, ka puta he tūponotanga.

1. Utu mānu. E pā ana ki te utu i te wā e mahi ana i runga ipurangi. He maha ngā wā ka whakamahia tēnei tikanga i ngā wā tuku hiko tārua. Mena he iti iho i te 12 volts, kāore e taea te utu, ā, ki te nui rawa, ka pā ki te mahi o te ara iahiko. Nō reira, ina mahi te utu mānu, ko te ngaohiko he 13.8 volts.

2. Huringa utu. E pā ana ki te utu katoa i te pākahiko hei whakahoki mai i te kaha. Ina utua katoatia, kāore te rihi e momotuhia hei ine. Ko te tikanga, he tata ki te 14.5 volts, ā, kāore te mōrahi e neke ake i te 14.9 volts. I muri i te momotu i te rihi mō ngā hāora 24, ko te tikanga he tata ki te 13 volts ki te 13.5 volts. Tata ki te 12.8 ki te 12.9 volts i muri i te wiki. He rerekē te uara ngaohiko motuhake o ngā pākahiko rerekē.

Ko te pūhiko lithium noa he 3.7v, ko te ngaohiko he 4.2v ina utua katoatia, ko te ngaohiko ingoa i muri i te hononga raupapa he 7.4v, 11.1v, 14.8v anake… ko te ngaohiko katoa e rite ana (arā, ko te ngaohiko putanga kore-kawenga o te rihi) he 8.4v, 12.6v, 16.8v… kāore e taea te 12v tauoti, pērā i te wā o te pākahiko rokiroki waikawa-mata he 2v, ko te kī he 2.4v, ko te ingoa anake he 6v, 12v, 24v… ngaohiko katoa (koia anō te ngaohiko putanga o te rihi) 7.2v, 14.4v, 28.8v… Kāore au i te mōhio he aha te momo pākahiko lithium āu?
Ko te putanga o te rihi hiko he 5V te nuinga, ā, ko te 4.9 volts he mea kāore i te paerewa. Ki te hiahia koe ki te whakamahi i tēnei rihi hiko hei utu tika i te pākahiko, e kore rawa e mahi, engari mena ka utua e te waea pūkoro, e te tauranga rānei, he ara iahiko whakahaere kei roto. Ka whakawhāitihia ki roto i te whānuitanga e whakaaetia ana o te pākahiko lithium, ki te kore te ara iahiko e pakaru, kaua e manukanuka ki tēnei.
