This FAQ addresses the most common questions from global buyers about power adapter customization, specifications, and inventory. It’s concise, value-driven, and tailored to B2B needs—no fluff, just clear, actionable information.

Q1: Can I print my company logo on the power adapter?

Of course! Your logo can be printed on all adapters. Simply provide a PDF or JPG file of your logo for a clear, professional print that perfectly matches your brand image.

Q2: What about DC cable length? Can it be customized?

• Standard length: 1500mm (1.5 meters) for all base models.
• Custom Length: We can provide the length you need according to your specific requirements (e.g., 1m, 2m, 3m, 5m, or other lengths).
• Notes for DC Cable Length of Power Adapters Exceeding 3000mm:
  • Cables with a length exceeding 3000~6000mm (3~6 meters) require pre-approval to ensure the adapter still complies with the U.S. Department of Energy (DoE) Level VI efficiency standard and the European ErP (Lot 7) efficiency standard (excessively long cables can cause energy loss).

Cables longer than 5 meters/8 meters may affect the output voltage accuracy (e.g., ±5% tolerance). We will evaluate your specific power solution (voltage/current) to confirm if the required tolerance can be achieved—there is no one-size-fits-all solution for this.

Q3: Are there color options beyond black and white?

• Standard colors: Black and white are available.
• Custom colors: We fully support custom color matching. You can provide your brand-specific color, or we can match colors according to the Pantone International Color Chart for a precise, consistent finish that stands out in the market.

Q4: What DC jack options do you offer?

• Standard options: 5.5×2.5mm and 5.5×2.1mm.
• Custom jacks: We can source/produce any DC jack size to match your end device’s port (e.g., smaller/larger pins, unique connectors).
• Alternative solution: If you prefer direct integration, we can supply adapters without a pre-attached DC jack—instead, the cable end is stripped and tinned for easy soldering to your device’s circuit.

Q5: Do you keep stock power adapters?

No, we do not maintain inventory. In the power adapter industry, no manufacturer stocks standard units—and for good reason:

Adapters are not standalone products. They are critical accessories designed to work with specific end devices (ICT Equipment, medical equipment, industrial tools, etc.). Every application has unique requirements:

• Different voltages/currents (5V/9V/12V/15V/18V/19V/24V/48V/30V/36V… 1A~20A… etc.).
• Varying EMC, safety, and efficiency standards (e.g., IEC/EN62368,IEC/EN61558,IEC/EN60601-1, DoE Level VI, ErP ( Lot 7 ) ect. ).
• Each country/region has unique AC PIN jack sizes and (safety) requirements (e.g., AC plug types in the US/Europe/UK).

We produce all adapters to your exact specifications to ensure full compatibility with your end product—this is the only way to guarantee reliability and performance.
