Why the power adapter is not powered

Issue Time:2007-01-23
What are the reasons for the power adapter not being powered? Shenzhen Lianyunda Xiaobian takes you to see why the power adapter is not powered.

First, the interface is different; most laptop power adapter brands have different interfaces, which means that using other brands of power adapters can not be plugged into the computer to load into your laptop. The difference in interface is relatively safe, because at least you will not plug the power adapter that does not match the current or voltage to power the laptop, causing damage to the computer hardware.

Second, the voltage is different; different brands of notebook computer power supply computer configuration single adapter voltage is not the same, for example: IBM is generally 16V, Dell is 20V, Hp is 18.5V, Sony is 19.5V and so on. It can be seen that even if the power adapter interface is the same, you cannot use different brands of laptop power adapters for power supply.

Third, the current is different; different brands of laptop power adapter current is also different, for example: IBM is 4.5 amps in general, Dell is 3.34A, Hp is 2.7A, Sony is 4.1A. In fact, the voltage and current of the same brand laptop power adapter are not the same. Therefore, even if you use a power adapter between the same brand of laptops, you must confirm the voltage and current specifications.

Shenzhen Lianyunda's power adapter has been widely used in various fields and has been well received by customers. Lianyunda has become a well-known enterprise in the power industry. Lianyunda Electronics warmly welcomes your presence and guidance!
