Can I use a power adapter with high voltage and current?
The adapter on the phone burned out 5.5v 500mA., Is it possible to replace the adapter 5.7v 800mA. Not dangerous?
Hello! Most likely not dangerous. What kind of phone is that? The fact that the voltage is a little more is unlikely to play any role, and the fact that the output current is more - moreover, the phone will take as much as it needs.
