Designed for Wearable & TWS Earbud Repair

🎧 TWS Earbud Power & Charging Circuit Testing

Use the SPPS-C305 as a controlled DC power source when testing TWS earbud charging circuits, power management circuits, and charging-related components during repair.

🔋 Battery & Power Consumption Testing

The adjustable output allows technicians to provide a controlled power source for wearable and earbud circuits while monitoring voltage and current consumption.

This can help identify:

• Abnormal current draw

• Power leakage

• Charging circuit faults

• Battery-related problems

• Power management issues

🔬 Miniature PCB Troubleshooting

Wearable devices and TWS earbuds use extremely compact PCBs with densely integrated components. The SPPS-C305 provides stable adjustable power for component-level troubleshooting and PCB repair.

⚡ Short-Circuit & Abnormal Current Diagnosis

When a wearable or earbud PCB has a suspected short circuit, technicians can use a controlled power supply to observe current behavior and assist with locating abnormal circuits or components.

⌚ Wearable Device Repair

Suitable for troubleshooting and testing the power circuits of:

• Smartwatches

• Fitness trackers

• Smart bands

• Wireless earbuds

• TWS charging cases
