Return & Refund Policy

Last updated: October 26, 2026

Thank you for shopping at eTOMMENS, operated by Dongguan Jike Electronic Technology Co., Ltd. This Return & Refund Policy applies to all orders of DC power supply products and related accessories purchased through our official website etommenspowersupply.com. By placing an order with us, you agree to the terms stated below.

1. Eligibility for Returns

We accept formal return requests within 30 calendar days counted from the date you receive the parcel. To be eligible for return, all returned goods must remain unused, unmodified, with intact original labels, stickers and factory packaging. Products must not show any sign of burn marks, overload damage, scratches or disassembly. Custom-made, customized parameter power supplies are non-returnable, except when factory manufacturing defects are confirmed by our technical team.

2. Damaged or Defective Goods Upon Receipt

Please inspect your package and products immediately after delivery. If items arrive broken, scratched, or fail to work correctly due to factory quality problems, you must submit evidence including clear photos, short test videos and tracking number within 7 calendar days after receiving the shipment. Our technical support team will review your materials. Once the manufacturing defect is verified, we will offer one of the following solutions: free replacement of the whole unit, free spare parts replacement, technical repair service, or full/partial refund, based on the actual condition of the product.

3. Items That Cannot Be Returned or Refunded

The following categories of products are excluded from our return and refund service:

• Custom programmed, customized voltage/current power supplies made according to your special requirements;

• Products damaged by wrong input voltage, overload, short circuit, improper wiring, wrong installation or user misuse;

• Goods disassembled, repaired or modified by yourself or third-party technicians without our written permission;

• Consumable accessories such as cables, terminals, connectors, fans;

• Orders that have passed the 30-day return application window;

• Goods that have been used in commercial continuous operation for a long time and show normal wear.

4. Return Shipping & Related Costs

If the return is caused by our quality fault: we will bear the reasonable return freight cost. We will provide you with the designated return address and shipping guidance. You need to use safe packaging to avoid secondary damage during transit.

If you apply for return for personal reasons, such as ordering the wrong model, changing purchase plan, or mismatch with your expected application scenario, you need to take charge of all return shipping fees, customs charges and handling costs. The original shipping fee we charged for delivering the goods will not be refunded.

5. Inspection & Refund Procedure

After we receive your returned package, our QC team will inspect the product within 3–5 working days. We will send you an email notification of the inspection result. If your return request is approved, the refund will be initiated. Refunds usually take 7–14 business days to arrive at your original payment account. The actual arrival time depends on the processing speed of your bank or payment service provider. We are not responsible for delays caused by third-party payment institutions.

6. How to Submit a Return Application

Do not send goods back before getting our confirmation. Please write an email to support@etommenspowersupply.com with these information: your order number, product model, quantity, reason for return, together with photos or video proof. Our team will reply within 2 working days and send you formal return instructions and return authorization. Returns sent without prior authorization will be rejected.

7. Partial Returns & Bulk Wholesale Orders

For bulk wholesale and B2B large orders, the return rule may follow the separate sales contract signed by both parties. This online policy serves as the basic rule; if there is a conflict with your signed PI or sales contract, the contract document shall prevail. Partial return is allowed only when the defective units are clearly separated and identified.

8. Policy Updates

We reserve the right to adjust this Return & Refund Policy at any time. The updated version will be published on this page with a revised date. The policy effective at the time you place your order applies to your transaction.
