7. Troubleshooting / FAQ
Q: What type of charger is compatible with this socket?
A: This charging socket is specifically designed for DYU Electric Bicycle models (D1F, D2F, D3F) and JETSON Bolt Pro/Bolt Electric Ride-On. Always use the original charger provided with your electric bicycle or a compatible charger specified by the manufacturer for these models.
