The Beginning of Bespoke Innovation|From brand logos, casing colours and packaging styles to plug types, voltage/current ratings, cable lengths and materials, we cater to every design requirement. Our specialist team supports and standardises the entire process, from small-batch prototyping to mass production, guaranteeing safe, compliant and high-quality delivery.
Quankang Technology focuses on providing diverse customization options for high-efficiency wall plugs and desktop power adapters. Our primary focus is to support customers by providing products, information, and support essential to their design activities. Whether it involves branding, mechanical adjustments, electrical modifications, or regulatory compliance, our dedicated team can customize external power supplies to meet your specifications.
Please understand that minimum order quantities and amounts may vary depending on the scope of customization.
However, our sales team will guide you through the selection process and assist in choosing the optimal options for your design needs.
We offer customizable branding options to reflect your company’s brand in the product design of power adapters. We will collaborate with you to determine the optimal placement for your logo, whether on the adapter label or directly engraved onto the case using techniques such as etching, embossing, or silk-screen printing. Our goal is for your adapters to proudly embody your company and brand identity.


We harmonize the color and texture of the adapter housing with your design concept. Utilizing Pantone® color swatches, we accurately reproduce your brand and product colors.
Design custom packaging tailored to your brand. Choose from eco-friendly options free of plastic or select custom materials incorporating your brand labels. We help prepare your products for market launch with personalized packaging solutions.


We offer a variety of standard DC plug options, including barrel-type, ElAl-type, and USB-type.
If these options do not meet your requirements, we can incorporate a plug provided by you into the design.
If design-related adjustments to cable length are required, we can accommodate them. We can extend or shorten cables while adhering to safety standards and regulatory requirements. Additionally, we can modify wire diameter and shape (round or flat).


If our standard adapters do not meet your performance requirements, we offer flexible electrical and mechanical adjustments within the enclosure. This includes minor voltage and current modifications, as well as grounding and shielding adjustments, to ensure optimal functionality tailored to your needs.
Safety regulations and efficiency standards are frequently updated, but we always ensure that our adapters meet the necessary requirements.


To sell products in today’s global market, specific safety certifications must be obtained for each region worldwide. We possess extensive experience guiding clients through the necessary certification processes, even beyond our standard service scope. Please feel free to consult us about how we can assist.
