K75 Hand-Held Refrigeration Fan: Customizable Logo, Color & Specifications for B2B OEM/ODM Projects
Our factory has built a complete customization service system relying on 8 professional small fan production lines, 20+ R&D engineers and a 10,000-square-meter production workshop, which can fully meet the diverse customization needs of B2B clients. The core advantages that make us stand out in the industry are as follows:
First, flexible production line support. Each of our production lines can be adjusted according to customized product parameters. Whether it is the replacement of fan shell materials, the upgrade of motor power or the adjustment of battery capacity, the production line can be quickly switched within 48 hours, solving the problem of high cost and long cycle of small and medium batch customization for B2B clients. Second, strong R&D and design capability. Our R&D team has rich experience in small fan structure design and function optimization, which can not only realize logo printing, color customization and appearance modification, but also develop new functions according to market demand, such as silent upgrade, long battery life extension and foldable structure design. Third, strict quality control for customized products. All customized small fans will go through the same 3-stage quality inspection as standard products, including incoming material check, in-line testing and final audit, ensuring the defect rate is less than 0.3%, which is far lower than the industry average. Fourth, fast delivery efficiency. We can complete the sample development in 14 days for general customization needs, and the bulk production lead time is only 7-10 days, which helps B2B clients seize market opportunities quickly.

2. One-Stop Small Fan Customization Process: Simple, Efficient and Traceable
We have simplified the customization process to 5 core steps, ensuring clear communication and efficient execution at each stage, so that B2B clients can easily grasp the progress without extra energy input.
Step 1: Demand Communication. Clients can tell us their specific needs, including product type (handheld/desk/foldable small fan), customization content (logo, color, material, function, packaging), order quantity and delivery time. Our professional sales team will reply within 24 hours and confirm all details with clients to avoid information deviation.
Step 2: Scheme Confirmation. Based on client needs, our R&D team will make a detailed customization scheme, including product design draft, material selection list, cost quotation and progress schedule. We will send the scheme to clients for confirmation, and revise it repeatedly until clients are satisfied.
Step 3: Sample Development. After the scheme is confirmed, our production line will start sample making. We use the same raw materials and production processes as bulk production to ensure the sample is consistent with the final product. During the sample making process, we will timely feedback the progress to clients and send the finished sample with test reports for client verification.
Step 4: Bulk Production. Once the sample is approved, we will arrange bulk production immediately. We will assign a dedicated project manager to track the production progress, conduct real-time supervision on the production line, and take photos and videos of key processes to let clients know the production status clearly.
Step 5: Quality Inspection and Shipment. After the bulk production is completed, we will carry out strict final quality inspection, including function testing, appearance checking and packaging inspection. All qualified products will be packaged according to client requirements, and the delivery will be arranged as scheduled. We will provide the full set of shipping documents and tracking number to ensure the products are delivered to clients safely and on time.
3. Successful Customization Cases: Satisfy Different B2B Market Needs
We have rich experience in serving different types of B2B clients, including retail chains, brand owners and e-commerce sellers, and have created many successful customization cases, which fully proves our strong customization capability.
Case 1: US Retail Chain Foldable Handheld Fan Customization. A well-known US retail chain needed a foldable handheld fan with brand logo and long battery life to meet the summer market demand. We customized the foldable structure to make the product easy to carry, upgraded the battery to 12-hour long endurance, and printed the client’s brand logo on the fan shell with high-precision technology. We completed the sample in 12 days and delivered 50,000 bulk orders in 25 days. The product was well received in the US market, and the client placed a repeat order soon after.
Case 2: European Brand Desk Fan Customization. A European brand hoped to launch a silent desk fan with customized color matching to fit their brand style. Our R&D team optimized the brushless DC motor to reduce the noise to less than 30dB, customized the exclusive color according to the client’s brand color system, and designed a simple and stylish appearance. The customized desk fan not only met the EU CE and RoHS certification standards, but also won high recognition from European consumers, helping the client expand the market share quickly.
Case 3: Asian E-Commerce Seller Small Batch Customization. An Asian e-commerce seller needed small batch customized handheld fans with unique patterns for holiday promotions. We supported small batch orders of 1,000 units, printed exclusive holiday patterns on the fan shell, and adjusted the packaging to gift boxes. We completed the production in 10 days, helping the client seize the holiday promotion opportunity and achieve good sales results.
4. Factory Production Line Support: The Foundation of High-Quality Customization
High-quality customization cannot be separated from the strong support of advanced production lines, which is exactly our core competitiveness. Our factory has 8 automated small fan production lines, with 200+ skilled workers operating 24/7, ensuring efficient production of customized orders. Each production line is equipped with professional testing equipment, which can test the function, performance and quality of customized products in real time during the production process.
