If a 5V appliance uses a 60W fast charger, it may lead to the following situations:
First of all, the output power of the fast charger far exceeds the power required by the appliance, which may cause the appliance to overheat or even damage.
Secondly, the electrical circuit may not be able to withstand such a high power input, which may lead to a short circuit or other failure. Finally, because the design of the appliance is not suitable for the output characteristics of the fast charger, it may cause the appliance to charge too fast, thus shortening the battery life. Therefore, in order to ensure the safety and normal use of electrical appliances, chargers that meet the power requirements of electrical appliances should be used.
The voltage of fast charge must have 5v output to be used, more than 5v is easy to charge the appliance.
