Without knowing any data about the power needs of the Expert Pad I can only
give you the advice to meet somebody who has a regulated laboratory power
supply. Connect the Expert Pad and increase the voltage carefully up to 6V.
If you can find any power rating or current rating on the Expert Pad adjust
the current limitation of the power supply accordingly. This is a save way
to find out:
- if the Pad is still alive
- what are the power needs of the Expert Pad
This will give a basis to decide which power adapter to chose.
