I have a uniden cordless phone which needs 9V DC 210 mA supply. The adaptor conked one day. Since I did not have time to get a new one immediately, I used a spare Motorola 6V DC 350 mA as a stop gab measure, the unit is functioning well. I have been using the phone for a week. My question is: will the base unit get affected because of 3V difference in supply in the long run?

You should be OK as long as the replacement charger actually charges the unit. If the unit is undercharged for a prolonged period of time, the NiCAD battery capacity may be slightly affected; Lithium batteries should not be afftected. If it's working OK with the replacement charger, I would just continue using it.

The chances are that the phone battery is either a 3.6V or 4.8V battery pack. Either way, the Motorola supply will have enough voltage to do the job. The only question remaining is current limitation. If the battery pack is not getting too hot during charging, then you're probably okay with the extra current from the Motorola. In fact, if there is no current limiter in the phone, the battery will actually charge faster with the Motorola than the OEM product. If there is a current limiter, there should be no difference at all in charge time or battery temp.

Using a lower voltage than what's required should have no damaging effects. It's only when you use a supply that is over the required amount (ie. using a 12v supply on a 9v device) that damage will occur. If anything, the range in which your cordless phone can operate will be lowered.
