I am wanting to replace the power supply for my Dreamplug (too chunky for a power-board and requires a converter to an AU plug). I have another power supply, however I am unsure it will work (without letting the magic smoke escape).
The supplied power supply is rated at 5v @ 3A and outputs 5.16v - 5.18v when measured with a (cheap) multimeter. The other power supply is rated @ 2.5A for 4.5v,6v, 9v or 12v. It outputs 4.90v - 4.93v according to the same multimeter when on the 4.5v setting.
Can I use the other power supply (checking polarity and ensuring that the device does not exceed 2.5A of current)?
