What is covered
BRIGHT POWER (CHINA) LIMITED (“SINVYX”) warrants that SINVYX products are free from defects in materials and workmanship for 18 months from the date of delivery, when used as described in the product manual.
What we do
If a covered defect appears during the warranty period, we will repair or replace the product, or refund the purchase price if we cannot. A repaired or replacement product keeps the remaining warranty period of the original; the period does not restart.
Who is covered
The original purchaser. Keep your order number or receipt. If the product was a gift or was bought through a reseller, the original order information is needed to make a claim.
How to make a claim
- Email info@sinvyx.com with your order number, the product model, a description of the problem, and photos or a short video.
- We reply within 1 business day and help you check common causes such as charging, cable and settings.
- If it is a covered defect, we tell you how to send the product back and arrange the replacement or repair.
We pay return shipping for approved warranty claims.
What is not covered
- Damage from misuse, dropping, crushing, submersion (the IP65 rating does not cover immersion), fire or extreme heat.
- Use outside the specified input and output range, or with unapproved chargers, cables or adapters.
- Repair, opening the case or modification by anyone other than SINVYX.
- Normal wear, including gradual capacity loss over time. Lithium batteries lose capacity with use; this is not a defect.
- Cosmetic damage that does not affect function.
- Damage caused by improper packing during return shipping.
Limitation of liability
To the extent permitted by law, our liability under this warranty is limited to the purchase price of the product. We are not liable for indirect or consequential loss, including loss of connectivity, data or income, or damage to devices connected to the battery. Some jurisdictions do not allow these limits, so they may not apply to you. This warranty gives you specific legal rights, and you may have other rights under local law that this warranty does not affect.
Wholesale and OEM orders
The same 18-month warranty applies to wholesale and OEM orders. Other details for those orders, such as how defective units are returned, replaced or credited, are set in the written contract for that order.
