Let usiPhone4STake advantage of，Battery capacity is1460mAh，If you use capacity6000mAh（MAh hour）Mobile power charging，According to the simplest algorithm，6000÷1460≈4。11。Dismiss， 6000mAhBattery should be charged4Secondary，But this is not the case.。Since the mobile power is a portable energy storage tool，During the power conversion process，Efficiency changes。
Let me briefly explain 易彤破壁机维修点 the charging principle of mobile power。Current built-in battery for mobile power（18650Polymer）Nominal voltage is3。7V，The standard input voltage of mobile phones and other digital products is5V。therefore，Mobile power supply needs to output by boost management board5VVoltage，Can charge your mobile phone and other equipment。
Practical power after boost conversion
as the picture shows，According to the rule of energy conservation6000mAHmobile power，Battery energy is6000mAH×3。7V = 22。2Wh（Watt hour），Boost conversion5VRear，The overall energy is constant but the power is22Wh÷5V = 4400mAH，Be like a cup3。will7Liter5Liter。After the first step，6000mAHThe original power is only left74％。This4400mAHIn fact, it can be provided to the mobile phone.。
Various losses during charging process
Next， What we have to do is to connect to mobile power and mobile phones with data cable.。Then the problem came again.4400mACan a power supply to the mobile phone battery?？The answer is of course not，During charging，These power levels still have a lot of loss：
1。 Circuit conversion loss。I believe that everyone knows that the mobile power will fever when charging.，The heat dissipated according to the conservation of energy is actually the energy of the built-in battery.。
2。 Resistance loss。When charging the phone，The built-in battery of the mobile power and the mobile phone battery are connected by circuit boards and wires.。we know，All conductors have resistance，No conductor has zero resistance（Super conductors are not within the scope of this discussion）。The main physical characteristics of the resistor are converted to heat。So during the charging process, the conductor will heat，When generating heat Energy loss and loss。
3。 Voltage loss。The discharge voltage of the lithium battery is not static.，The safety range of the discharge voltage is4。2V-2。7V，Power conversion will also be different。Generally, the discharge voltage range is3。6-3。in9VCan release battery power between80％Or more，If this range is exceeded，Power loss will increase。
4。 Electricity loss。Mobile power is not only charged when charging the phone，Powering other components, especially the screen is a big power consumption。
5， Your own loss。During charging，Mobile power needs to consume power to maintain its own operation。The power supply is also provided by the built-in battery.。
Through the above losses，The actual power reaching the mobile phone battery is about4400mAHActual power85％。That is3774mAH。From6000mAHBattery capacity，The actual output power is3774mAH，During this period，About38％Power loss。Dismiss，The actual 易彤沙冰机维修 conversion efficiency is only about approximately62％。Next， Author attached two photos，Tell everyone a6000mAhMobile power，How many times I can charge mobile phones?？
Through the above explanation，I believe everyone should understand in practical applications. The actual operation conversion efficiency of mobile power is very critical。Mobile power on the market，basically， The conversion efficiency in actual operation is60％to68％。Aruhai Lu Tong mobile power，Power solutions are developed，There is also a circuit board Mold houses， Transformers and other components are produced independently in our own technology parks。Control the quality link in each production step！Charging，Basic 易彤破壁机不转 stayARUNThe actual operation conversion efficiency of Hai Luotong mobile power products is68％?70％。More than the program design and component selection requirements90％Conversion efficiency standard，selectARUN Hailutongmobile power。therefore，Actual conversion efficiency for mobile power，Everyone must have a clear understanding，During the purchase process，Don't be misleaded by merchants。with，Mobile power must be understood correctly， Created such a convenient product for everyone。
