Frequently Asked Questions

Can I use a 12V 3A adapter for a 12V 1A device?

Yes, as long as the voltage matches exactly. The current rating indicates maximum capacity - higher amperage adapters are safe but never exceed voltage requirements.

Why does my adapter get warm during use?

Normal operation may cause temperatures up to 60°C. Discontinue use if: 1) Case deformation occurs 2) You smell burning 3) Temperature exceeds 70°C.
