^{The power adapter has a variety of parameters, so the adapter cannot be used to charge. Before selecting a power adapter, first determine the three adaptation conditions.}

^{First, the interface of the adapter matches the device;}

^{Second, the output voltage must be the same as the rated input voltage of the load (mobile device), or the voltage range that the load (mobile device) can withstand, otherwise the load may be burned (mobile device);}

^{Third, the output current of the power adapter should be equal to or greater than the current of the load (mobile device) to provide sufficient power;}

^{The following three conditions are analyzed.}

^{First, the mismatched interface should not be inserted without professional knowledge, otherwise it will be dangerous.}

^{Second, for the reason why the voltage is consistent, in principle, this is the case - the voltage is not enough to drive the load, the battery can not be charged properly, the popular point is that supply is in short supply.}

^{Third, for the reason why such a current configuration is required, this involves the principle of the circuit. Everyone knows that the power supply has an internal resistance, and the larger the internal resistance, the greater the loss. Therefore, when the manufacturer produces this adapter, it will determine the no-load output voltage within a certain range according to the internal resistance. The current threshold corresponding to the voltage threshold is the current nominal value we see. The current value is higher. The greater the adapter load capacity, the better. So choosing an adapter with a slightly larger current will not only damage the battery, but will make charging faster.}
