Power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB. Its working principle is converted from an AC input to a DC. Output; according to the connection method can be divided into wall-mounted and desktop. Widely used in security cameras, set-top boxes, routers, light bars, massage instruments and other equipment.

Q1: Will the adapter burn out? Is there a fire hazard?
A1: The shell is made of fireproof material, do not worry about this problem.
Q2: I want to make the packaging box as our design, can you do it as our requirement ?
A2: Absolutely we can do it as your design. But you should provide the neccesery information (material,
size, printing,shape and so on.)
Q3: What`s your warranty?
A3: Our warranty is 3 years.
Precautions For Use Power Adapter
The power supply voltage is the same, the output current is different, and it can be used on the same notebook. The basic principle is that a large nominal current source can replace a small nominal current source. It is estimated that some people will think this way, think that the power of the large nominal current will burn out the books, because the current is large. In fact, how much current depends on the load when the voltage is the same, huh, huh, think about the physics of junior high school. When the notebook is running at a high load, the current is larger. When the notebook enters standby mode, the current is smaller, and the power source with a large nominal current has sufficient current margin. On the contrary, there is no problem in using a 56w power supply instead of the 72w. The reason is that the design of the power adapter usually has a certain margin, and the load power is less than the power supply, so this replacement is feasible in general use. However, the remaining power supply margin is very small, once your notebook has a lot of peripherals, such as two usb hard drives, then the cpu runs at full speed, and then has a base, which comes to a CD-ROM full-speed read disk, plus Charging the battery is estimated to be dangerous. You should be able to cook your eggs at any time by hand. Therefore, it is best not to use a small current source instead of a high current source.
