Device warranty and SN verification

Star Miner products include a 6-month limited warranty beginning on the delivery date. Every device has a unique serial number (SN), which is used to check its warranty period, warranty status and service eligibility.

Covered under normal use

• Non-user-caused failure of the main device hardware.
• A device that cannot start normally due to a confirmed hardware fault.
• Quality-related failure of core components such as chips, mainboards or fans.
• Other product-quality issues confirmed by Star Miner support.

Global warranty policy

Star Miner devices that meet the official warranty requirements are eligible for global warranty service. Service availability, return address, logistics arrangements and processing time may vary by country or region. Warranty eligibility is verified using the device SN and original order information.

How to submit an after-sales request

Contact official support and provide complete information so the team can diagnose the issue efficiently.

1. Provide the original order information.
2. Provide the device serial number (SN).
3. Describe the issue and when it started.
4. Attach clear photos or a short video showing the problem.
5. Follow the remote troubleshooting instructions provided by support.

Conditions that may affect warranty coverage

Free warranty service may not apply when damage or failure results from:

• Unauthorized disassembly, modification or overclocking.
• Flashing unofficial, native Bitaxe or other-model firmware.
• Water, humidity, corrosion, dropping, crushing or impact.
• Unstable voltage, an incorrect power supply or an unqualified adapter.
• High temperature, dust, poor ventilation or other improper operating conditions.
• Unauthorized third-party repair.
• A removed, altered, damaged or unreadable SN or warranty label.
• Natural disasters, fire, lightning or other force-majeure events.
• Products outside the 6-month warranty period.

Official firmware, updates and remote maintenance

Installing third-party firmware, native Bitaxe firmware or firmware designed for another model may cause abnormal operation and may affect warranty coverage. Use official Star Miner firmware only.

Official firmware is continuously improved. When necessary, Star Miner may release updates related to security, stability, compatibility or important product features. Keep the device online with stable power and network connectivity during an update.

Replacement parts and accessories

The following replacement parts may be available through official support. Compatibility must be confirmed using the device model and SN before ordering.

Repair, replacement and shipping

Shipping costs

For a confirmed quality issue within the warranty period, Star Miner covers the repair cost. The customer is responsible for shipping the product to the service center. Return shipping after repair is determined through mutual communication. For user-caused damage, improper use or out-of-warranty service, the customer is responsible for repair and round-trip shipping costs.

Repair and replacement

Equivalent or similar-performing parts may be used during repair. Replaced parts become the property of Star Miner. If a device cannot be repaired, Star Miner may offer the same model or a product of equivalent value. Repair or replacement does not restart or extend the original warranty period.

Usage recommendations and important notes

• Use the original power adapter or a certified equivalent that meets the specifications.
• Operate the device in a dry, clean and well-ventilated environment.
• Avoid frequent power interruptions, incorrect wiring and prolonged abnormal operation.
• Regularly check device temperature, status and network connection.
