Warranty Policy

Last Updated: October 29, 2026

1. Overview

This Warranty Policy applies to all power supply products supplied by Dongguan Jike Electronic Technology Co., Ltd. We provide limited warranty coverage for manufacturing defects in materials and workmanship for our products. This warranty is only valid for the original purchaser and is non-transferable. This policy defines the warranty period, covered failures, excluded situations, claim procedures and after-sales arrangements.

2. Warranty Period

Unless otherwise stated in the product specification sheet, our standard warranty period is 24 months (2 years) from the date of shipment from our factory. For customized special power supplies, the warranty term shall follow the written agreement confirmed in the sales contract. The warranty period will not be extended, renewed or restarted after product replacement or repair.

3. What This Warranty Covers

During the valid warranty period, we will repair or replace the product free of charge, if the product fails due to defects in raw materials or factory manufacturing. Qualified warranty issues include:

  • Abnormal output caused by internal component failure that originates from production;
  • Circuit board failure without signs of external damage or misuse;
  • Failure of built-in components that conform to our original design specifications;
  • Functional breakdown that occurs under normal operating conditions within the rated parameters of the product.

4. What This Warranty Does NOT Cover

This limited warranty does not apply to damage or failure caused by the following conditions:

  • Damage caused by improper installation, overvoltage, overcurrent, reverse connection, wrong wiring or operation beyond the rated parameter range;
  • Physical damage, crack, burn, water ingress, dust, corrosion, lightning strike or surge damage from the customer’s side;
  • Modification, disassembly, rework, repair attempted by third parties without our written authorization;
  • Normal consumable parts and aging from long-term natural use, such as cooling fans, electrolytic capacitors;
  • Damage caused by improper storage, transportation, collision or packaging after leaving our factory;
  • Products purchased from unauthorized resellers, counterfeit goods or serial number removed/altered products;
  • Project losses, downtime loss, profit loss, indirect economic loss and other consequential damages caused by product failure.

5. Warranty Claim Process

When you find a product failure and intend to file a warranty claim, please follow the steps below:

Step 1: Contact us by email at jk.tech688@gmail.com. Please provide the order number, product model, quantity, production date code, detailed failure description, photos or short test videos of the defective unit.

Step 2: Our technical team will evaluate the problem and judge whether it falls within warranty coverage within 3-5 working days. We may ask you to run simple tests and provide test data.

Step 3: If approved, we will inform you of the return shipping address and return requirements. The customer shall bear the freight cost for sending defective goods back to our factory unless we separately agree in writing.

Step 4: After we receive and inspect the returned unit, we will arrange repair or replacement. We will ship the repaired or new replacement unit back to you. The outbound freight of replacement goods will be negotiated by both parties.

6. Replacement & Repair Terms

We reserve the right to choose repair or replacement as the solution. Replacement products may be equivalent refurbished units or new units of the same model. If the original model is discontinued, we may replace it with a compatible alternative model with similar electrical performance. We do not guarantee the same appearance of the alternative product.

7. Out-of-Warranty Service

For products outside the warranty period, or damage excluded by this warranty policy, we still provide paid maintenance service. We will quote you the cost of spare parts and labor before repair. You can decide whether to accept the paid repair solution.

8. Limitation of Liability

This is our exclusive limited warranty. We do not provide any other implied warranties including merchantability and fitness for a particular purpose beyond the scope written here. Our maximum total liability under this warranty shall not exceed the original purchase price of the defective product.

9. Policy Revision

We reserve the right to revise this Warranty Policy at any time. The updated version will be posted on this page with the latest revision date. The warranty terms effective at the time of your order shall apply to your purchased products.
