GMCELL USB Rechargeable Battery Review: Voltage Testing and Power Bank Charging Performance

Hais txog GMCELL

Nyob rau hauv lub ntiaj teb no lub hwj chim- tshaib plab, rechargeable roj teeb tau dhau los ua ib tug staple uas yog ob qho tib si yooj yim thiab ib puag ncig tus phooj ywg.GMCELL yog ib tug zoo-paub lub npe nyob rau hauv lub roj teeb tsim kev lag luam thiab muaj ntau yam ntawm USB rechargeable roj teeb. Lub hom phiaj ntawm qhov kev tshuaj xyuas no yog los ntsuas qhov ua tau zoo ntawm GMCELLUSB rechargeable roj teeb, nrog rau kev tsom mus rau qhov ntsuas hluav taws xob.

Kev ntsuas hluav taws xob

Txhawm rau kuaj qhov hluav taws xob ntawm GMCELL USB rechargeable roj teeb, siv qhov ntsuas qhov tseeb digital multimeter. Cov roj teeb tau them tag nrho siv tus qauv USB chaw nres nkoj ntawm lub khoos phis tawj, ua raws li lub sijhawm pom zoo them los ntawm GMCELL. Tom qab them nyiaj, qhov qhib-circuit voltage (OCV) ntawm txhua lub roj teeb tau ntsuas tam sim ntawd. Tom qab ntawd, cov roj teeb tau raug simulated load test. Ib tug resistor nrog tus nqi sib npaug rau cov khoom siv hauv tsev ib txwm muaj (xws li lub xov tooj cua portable) tau txuas nrog hla lub roj teeb terminals, thiab qhov voltage tau ntsuas dua nyob rau hauv cov xwm txheej no.

Cov txiaj ntsig

• Qhib - Circuit Court voltage: GMCELL USB rechargeable AA roj teeb, ntsuas ntawm 1.5V, pom qhov nruab nrab qhib - hluav taws xob hluav taws xob ntawm 1.52V thaum them tag nrho. Qhov no qhia tau hais tias cov roj teeb tau zoo - tsim thiab tuaj yeem ncav cuag qhov hluav taws xob ze rau tus nqi nominal. Lub AAA roj teeb, kuj nrog lub nominal voltage ntawm 1.5V, muaj qhov nruab nrab OCV ntawm 1.51V. Cov txiaj ntsig no qhia tias GMCELL roj teeb muaj qhov kev them nyiaj ruaj ntseg uas tuaj yeem nqa cov roj teeb rau lawv cov qib siab voltage.
• Loaded Voltage: Nyob rau hauv lub simulated load, AA roj teeb tswj qhov nruab nrab voltage ntawm 1.45V, uas yog ib tug ruaj khov kev ua tau zoo heev. Qhov kev poob qis hauv qhov hluav taws xob me me no qhia tau hais tias lub roj teeb muaj peev xwm xa tau lub zog sib xws rau cov khoom siv. Cov roj teeb AAA tau pom qhov ua tau zoo sib xws, nrog qhov nruab nrab loaded voltage ntawm 1.43V. Qhov tso zis hluav taws xob ruaj khov no yog qhov tseem ceeb rau cov khoom siv uas xav tau lub zog tas li kom ua haujlwm tau zoo, xws li cov chaw taws teeb tswj thiab cov khoom ua si me me.
