The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It puts the power supply externally and connects it to the host with a line, which can reduce the size and weight of the host. Only a few devices and electrical appliances have the power supply built in the host. Inside. Laptop power adapter
Since the inside of the power adapter is a switching power supply that works under high voltage and high current, the work load is relatively heavy, and it is a fully enclosed structure. There is no heat dissipation hole on the shell and no internal fan to assist heat dissipation. Therefore, the power adapter is working The internal temperature is high. In the hot summer, you can feel hot to touch the surface with your hands, and the internal temperature is even higher. Therefore, it must be properly maintained and maintained during daily office and entertainment.
The batteries and power adapters of different models of the same brand cannot be used universally because the capacity of each laptop battery is different. The battery capacity is small, the power adapter input power is also small, and the battery capacity is large, and the power adapter input power is also large. It is precisely because of the differences that different models of the same brand of laptop batteries and power adapters cannot be used in common. Laptop power adapter
The characteristics of the switching power supply are: high-speed pass and cut-off with a circuit-controlled switch tube. The direct current is converted into high-frequency alternating current and supplied to the transformer for transformation. The wall-mounted Chinese-standard certified power adapter then generates the required set Or multiple sets of voltage! Plug-in type Chinese-standard certified power adapter and it is not very hot during operation!! The cost is very low. If the 50HZ is not changed to high frequency, the switching power supply is meaningless
