I have a Radio Shack cordless phone which is rated as: 12Volts, 300mA & 8Watts. Where the center pin is +.
This was for an input voltage of 110volts.
I've moved somewhere that has 220Volts output now. I've been using a converter to step down the wall voltage (220 > 110) but found taht the converter heats up quite a bit & it's plugged in 24 hrs a day for the phone...
I've tried to find a AC>DC transformer that matches the original, but have had no success.....
So what parameters need to fall in what range? I suspect the voltage must stay at 12V ideally & the current can be slightly lower but preferably slightly higher??
or is this oversimiplified?
