Returns & Refunds Policy
1. Scope
This policy applies to standard catalog products manufactured by EVEVSPOWER / Yiwen Technology Co., Ltd. OEM/ODM and custom-engineered products are handled under the relevant project agreement; where no agreement exists, this policy applies to the extent stated below.
2. Inspection on arrival
Please inspect all goods immediately upon receipt. Report any quantity discrepancy, wrong model or visible transport damage in writing within 7 days of receipt, with photos and the delivery note number. Late reports may affect our ability to claim from the carrier and your eligibility for free replacement of that specific issue.
3. Defective or DOA products
- Dead on arrival (DOA): if a unit fails to operate on first use within 30 days of receipt under the rated specifications, we will replace it free of charge or issue a full refund, at your choice.
- Other defects: units that fail during normal operation within the 24-month warranty period are repaired, replaced or refunded at our option after inspection.
- Warranty claims require the model number, order number, a description of the fault, and photos or a short video of the test conditions (input/output voltage, load and failure symptom). This helps our engineers diagnose quickly and prevents unnecessary return shipping.
4. RMA process
- Contact us at allan@everspower.com or +86 131 131 33518 (Tel / WhatsApp) with the details above.
- We issue an RMA number and return instructions within 1–2 business days.
- Return the goods in their original or equivalent protective packaging with the RMA number clearly marked. For confirmed quality defects, we will provide a return address in China and, where agreed, cover the return shipping cost or credit it against the next order.
- We test the returned units within 5–10 business days of receipt and confirm the outcome (repair, replacement, credit or refund).
5. Non-returnable items
- Custom, OEM/ODM or modified products (unless defective or as agreed in the project contract);
- Products damaged by misuse, incorrect wiring, over-voltage, reverse polarity, moisture ingress beyond rated protection, or unauthorised modification;
- Products returned without an RMA number or after expiry of the applicable warranty period;
- Consumables and components with evidence of physical damage in transit caused by the buyer’s packaging.
6. Refunds and replacements
- Approved refunds are issued to the original payment method within 7–14 business days after our inspection confirms the defect.
- Replacement units ship as soon as stock or production allows, normally within 15 days.
- Shipping costs are not refunded unless the error or defect is ours. If you refuse a shipment without cause, original and return freight charges are deducted from any refund.
- For volume orders, we may instead issue a credit note against your next order if you prefer.
7. Warranty summary
Standard catalog products: 24 months from shipment against defects in materials and workmanship under normal use within rated specifications. The warranty excludes faults caused by misuse, unauthorised modification, or operation outside the documented input/output and environmental limits. OEM/ODM products: as defined in the project agreement.
8. OEM/ODM and volume orders
For custom projects we agree acceptance criteria, sampling (first article) and defect-rate targets in the contract. If the agreed outgoing quality level is exceeded, we will either rework or replace the affected batch or issue a credit note, at our option, in line with the project agreement.
