Power purchase notice:
one Voltage:Voltage is very important. Because the voltage is too high or low, it will affect the normal use of the notebook. If the voltage is too high, it will cause damage to the notebook. Generally speaking, the voltage deviation 5% will not affect the normal use of the notebook. Commonly used voltage values ??are generally around 15/20V
Two current:The current value is actually the power of the adapter. Everyone knows that the power is actually the product of voltage and current. Because the current value is not constant when the notebook is working, the current marked by the adapter is the maximum current value of the adapter. The basic principle is that a power supply with a large nominal current can replace a power supply with a small nominal current. Otherwise, it may cause insufficient power.
three Socket type: The socket refers to the socket where the adapter is plugged into the notebook. Choosing a socket generally mainly considers the following factors: size——Refers to the outer and inner diameter of the socket. Generally, the most commonly used socket size is 5.5mm in outer diameter and 2.5mm in inner diameter, which is the same as most routers or cats. shape——Most of the sockets are round, and some have pins inside. Some HP sockets are bullet-shaped.
