A stable power supply and proper installation are essential for getting the best performance from your LAMTTO RC Series CarPlay display.
If your device won't turn on, keeps restarting, or your mount keeps falling off — this complete guide covers all common power and accessory issues with simple step-by-step solutions.
Device Won't Turn On (No Power / No Response)
Symptoms: Screen stays black, no response after plugging in, device does not boot.
How to Fix:
- Check the car charger indicator light
- If no light → check your car cigarette socket
- Always use the original charger
- Third-party chargers may not provide enough voltage
- Test at home using a 5V 2.5A–3A wall adapter
- Do NOT use a computer USB port
Diagnosis:
- Works at home → Car charger is faulty
- Still not working → Device issue (needs replacement)
No Battery / Won't Stay On Without Power
LAMTTO RC devices do NOT have built-in batteries. Device only works when plugged in. This is designed for safety.
Random Shutdowns / Keeps Restarting
Common Causes:
- Weak power supply
- Loose connections
- Interference from other devices
Fix Steps:
- Use original car charger
- Plug directly into cigarette socket
- Do NOT use splitters or adapters
- Do NOT charge your phone with same charger
- Keep phone at least 30cm away
- Remove SD card and test
- Disconnect rear camera
- Test with home power adapter
Device Restarts When Charging iPhone
iPhone charging draws power → device voltage drops. Do NOT charge phone using same charger — use separate charger.
Suction Mount Won't Stick / Falls Off
- Use adhesive pad
- Clean surface
- Apply and wait 24 hours
- Attach mount
Adjust position, height, and angle properly to avoid blocking your driving view.
Power Requirements
- Voltage: 5V
- Power: under 3W
- Must use original adapter
Final Thoughts
Most power and accessory issues come down to stable power supply and proper installation. Using the original charger and correct setup will prevent most problems.
