I-portable hand warmer, eyaziwa nangokuthi isifudumezi sesandla sokushaja i-USB, ayikakhi igama elihlanganisiwe emakethe. Lolu wuhlobo olusha lomkhiqizo we-elekthronikhi onikwa amandla amabhethri futhi unokudlulisa ukushisa kwangaphandle okuzinzile. Izinga lokushisa lokushisisa lisukela ku-45 ℃ liye ku-65 ℃, futhi isikhathi sokushisa esiqhubekayo ngokuvamile singaphezu kwamahora angu-4. Ngenxa yokuphatheka kwayo, ithandwa kakhulu ngabathengi.
Okwamanje,izinga lezifudumezi-zandlaezithengiswa emakethe ziyahlukahluka kakhulu, futhi abakaze bathole ukukhushulwa okubalulekile. Amabhizinisi amaningi akhiqizayo awazange anake ukuphepha kwezifudumezi zezandla ezishajayo, futhi umkhawulo wezobuchwepheshe uphansi. Ngakho-ke, kubalulekile ukugwema izigameko zokulimala okungenzeka!
Isifudumezi sesandla esishajayo sifana nesakhiwo samandla esiphathwayo, esihlanganisa i-casing, i-electronic circuit, ibhethri, nento yokushisisa. Amabhethri e-lithium ion (abuye aziwe ngokuthi "amabhethri e-lithium-ion") avame ukusetshenziswa ekukhiqizeni amabhange kagesi ahambayo aphinde asetshenziswe njengezingxenye eziyisisekelo zokuphakela amandla emikhiqizweni enjalo.
Isakhiwo esijwayelekile sokwakheka kwesifudumezi sesandla esishajayo
Uma kuqhathaniswa nezifudumezi zezandla zokugcina ezishisayo, nakuba izifudumezi zezandla ezishajwayo zingenazo izici eziyingozi njengokuchaphazwa koketshezi olunezinga lokushisa eliphezulu, zisengadala ukusha lapho zisetshenziswa ngokungafanele ngenxa yesikhathi eside sazo sokusebenza.
Uma kuqhathaniswa namabhange kagesi eselula, nakuba izifudumezi zezandla ezishajayo ngokuvamile zincane ngosayizi futhi ziphansi ngomthamo ngenxa yokuphatheka, amapuleti awo okushisa angaphakathi angabangela amabhethri e-lithium-ion ukuthi asebenze ezindaweni ezishisa kakhulu isikhathi eside. Ukwengeza, indawo encane yangaphakathi kanye nezinga elithile lokuklanywa kokushisa kwenza kube nokwenzeka ukuba umlilo uqubuke uma kunezimo ezingavamile njengokushisisa okungalawuleki noma ukushajwa ngokweqile kwesekethe emfishane uma kukhona amaphutha ekwakhiweni kwesekethe yokuvikela nokulawula, futhi uma impahla yegobolondo ayikwazi ukuvimba umthombo ovuthayo osetshenziswayo.
Ngakho-ke lapho ukhetha imikhiqizo enjalo, ungagxili nje emananini aphansi nokubukeka okuhle, noma ngabe ingasetshenziswa ngokuphepha kuyinto ehamba phambili.
Iziphakamiso zokuthenga ezincane:
1. Hlola ukuthi imanuwali yomsebenzisi womkhiqizo, isitifiketi sokuvumelana, ikhadi lewaranti, kanye nezinsiza kuphelele.
2. Hlola uphawu lokuhweba kanye ne-nameplate, khetha imikhiqizo enabakhiqizi abasemthethweni nezimpawu zokuthengisa ezibhalisiwe, futhi ungathengi imikhiqizo ngaphandle kolwazi. Ukuhlonzwa kwezimbobo zokufakwayo nokuphumayo zomkhiqizo (izixhumanisi zokushaja nokukhipha) kufanele kucace futhi kunembile, ugesi olinganiselwe wokufakwayo nokukhiphayo kanye namanani amanje kufanele akhonjwe ngokugcwele, futhi inani lomthamo olinganiselwe kufanele likhonjwe ngokucacile.
3. Kumele kuqashelwe ukuthi umthamo webhethri womkhiqizo awulingani nomthamo wawo wokuphuma osebenzayo. Ngakho-ke, umuntu akufanele abheke kuphela ulwazi lomthamo olufana ne-10000mAh ephawulwe ngokugqamile emkhiqizweni, kodwa futhi ahlole inani lomthamo olinganiselwe kumapharamitha wokucaciswa, okuwumthamo wangempela wokuphumayo.
4. Abathengi akufanele balandele ngokuphuphutheka amanani aphansi nokubukeka kahle lapho bethenga, kodwa kufanele balinganisele izidingo zabo kanye nohlobo lomkhiqizo, isithunzi nolunye ulwazi. Ngaphezu kwalokho, kufanele bakhumbule ukucela ama-invoyisi ngemva kokuthenga izimpahla ukuze bavikele amalungelo abo nezintshisekelo zabo ezisemthethweni.
5. Hlola usuku lokukhiqiza lomkhiqizo bese uzama ukukhetha umkhiqizo oshisayo oshisayo okhiqizwa ungakapheli unyaka owodwa. Uma idethi yokukhiqiza iyinde kakhulu, umthamo webhethri uzoncishiswa, okuzothinta umuzwa womsebenzisi womkhiqizo.
6. Ngesikhathi sokusebenzisa, zama ukugwema ukubangela ukuba umkhiqizo uwe. Uma izinga lokushisa liphezulu kakhulu kunezinga lokushisa lokusebenza (45 ℃~65 ℃), yeka ukulisebenzisa ngokushesha futhi ulibeke endaweni evulekile kude nabantu.
