[QUOTE="kubusi, post: 748567, member: 19010"] Such a device exists about the size of a 24 pin IC, they can be salvaged off old scrapped PC motherboards and most are marked 5v to 9v, I am not sure as to the available current from them but that information will be found on the Internet. I have a few laying around somewhere which were harvested from old computers. Alternatively without the trouble of building up the device just get hold of a wall cockroach as I call them that puts out 9 volts from a stepdown transformer, they should be freely available with current ratings of up to 1 amp. One point to be aware of the cellphone chargers these days are switchmode and put out a lot of noise that can be picked up by nearby radios and audio systems unless they are adequately shielded [/QUOTE]
