Our 12V3A desktop adapter Customization process
Step1:If you can choose double line
The 12V 3A desktop power adapter is available in two configurations: one with an integrated AC cord and one that uses a detachable AC cord. If you choose the version with an integrated AC cord (as shown in the image), you simply need to specify the AC plug type (e.g., US, EU, UK, or AU standard), the DC plug dimensions (common sizes include 5.5×2.1mm and 5.5×2.5mm, referring to the outer and inner diameters of the DC connector), and the desired lengths for both the AC and DC cables.
Step2: If you choose to match the AC line
First, you need to select the appropriate connector for the AC power cord. As shown in the image, the common types include the C13 (rectangular/kettle-style), C5 (cloverleaf/triangular), and C7 (figure-eight) connectors. When ordering a custom AC power cord, be sure to specify the corresponding connector type (one end of the cord will feature a plug-such as those used in the US,EU,UK, AU plug -while the other end will have the matching connector).
Step3:Confirm AC plug
Regarding AC plugs, we offer a wide range of customizable options. As shown in the image, these include Australian-style (2-pin or 3-pin), European-style (2-pin or 3-pin), Chinese-style (2-pin or 3-pin), American-style (2-pin or 3-pin), and British-style (3-pin) plugs, as well as large and small South African-style plugs, among others.
Step4:confirm DC head
We offer a wide range of customizable DC plugs. As shown in the image, this includes various sizes-such as 5.5*2.1, 5.5*2.5, 4.0*1.7, 3.5*1.35, 2.5*0.7, and 2.0*0.6-available in both straight and right-angle configurations. We also provide Micro, Micro 5P, Mini 5P, Type-C, USB, Apple-compatible, and 2.5mm audio plugs, among others.
Step5:Confirm DC cable length
Regarding the length of the DC cable, shorter is generally better. Our standard length is 1.2 meters, though 1.5-meter and 1.8-meter options are also available. It is best not to exceed 2 meters, as longer cables result in greater voltage drop. If a longer cable is strictly necessary, it can be customized to exceed 2 meters; however, the output voltage and current specifications of the power adapter may also need to be adjusted accordingly. Similarly, for AC cables, standard lengths include 1.2 meters, 1.5 meters, and 1.8 meters.
Step6:This is a matched AC line Adapter
His AC cord plugs into the main body of the adapter, which differs from the design of a two-wire (2-pin) adapter, where the AC cord is connected directly to the internal circuit board. Therefore, if you opt for a two-wire configuration when customizing a desktop-style adapter, there is no need to select an AC connector (terminal); all other customization steps remain the same.

Our Product Advantages
1. High-quality PC casing: Our power adapters are encased in durable alloy plastic with shock-resistant and drop-resistant properties. This ensures a sturdy and reliable structure for long-lasting use.
2. Seamless welding process: Our power adapters undergo a cutting-edge ultrasonic seamless welding process that effectively prevents dust and extends the product's service life.
3. Pure copper wire core: Our power adapters are equipped with pure copper wire cores that provide excellent electrical conductivity and deliver reliable power supply.
4. Top-grade transformer: three-layer insulated wire, imported magnetic core, complies with EMC standards, and can withstand high-voltage tests of about 4000V or more.
5. Efficient heat dissipation system: The internal front of the power supply is covered with aluminum fins with a large surface area, which effectively absorbs and dissipates internal heat to keep the power supply running at the optimal temperature.
