A: Huawei 40-watt charger cannot be charged with 60-watt fast charge. First of all, the model does not match and cannot be charged. Second is the difference in electrical power. According to the definition of electrical power, the amount of work done by the current per unit time is called electrical power. The Huawei 40-watt charger charges 40 joules per second, and the electric power is 60 watts of fast charge per second is 60 joules. Charging must follow scientific principles, the model does not match can not be charged.
No, if Huawei's mobile phone only supports 40W fast charge protocol, then it can only be charged according to 40W charging power. If you choose a 60W charger, the charging speed can reach 40W, but if you use a 40W charger to charge a 60W mobile phone, the power can only reach 40W.
Huawei 40 watt charger can charge 60 watts fast charge, as long as the voltage matches. You don't have to worry about too much power will output too much current, the output current will be based on the actual size required. Therefore, it is not only available but also extremely difficult to use overheating advantages for a long time (for example, the 20A large electric meter current at home has already burned out a single light bulb in the room).
can not
As described, 60w fast charge cannot be used. Or can use 60w charger, charging speed can only reach 40w
