Q1: Do you offer OEM/ODM custom service for power products?
A: Yes, absolutely. We offer both OEM (your brand, logo, packaging) and ODM (we help design/develop products based on your ideas or samples). We have experience working with well-known companies in the industry, and we are confident we can bring that same quality and reliability to your projects. Your brand and ideas are safe with us.
Q2: What voltage options (12V/24V/36V/48V/60V/68V/110V) can you supply for power supplies? Can you customize voltage?
A: We offer standard voltages including 12V, 24V, 36V, 48V, 60V, 68V, 110V depending on the specific item.
Q3: Can I get a sample order for quality testing?
A: Yes, sample orders are welcome to test quality. Mixed samples are acceptable. We also have overseas warehouses, so you can receive samples faster.
Q4: What is your minimum order quantity (MOQ) for sample and bulk orders?
A: Our MOQ is low. For sample checking, 30 pieces are available.
Q5: What are your shipping methods, delivery time, and logistics options?
A: We work with reliable shipping logistics partners. Depending on your country, our sales team can recommend dedicated shipping routes for better service and lower prices. Specific delivery times can be provided upon request.
Q6: How do you handle defective products under warranty?
A: First, all our products go through a strict quality control system, so the defect rate is very low. Second, during the warranty period: For small quantities, we will include new products with your next order. For defective batches, we will repair and resend the products, or we can discuss a solution (including a credit or replacement) based on the actual situation.
