DC Power Supplies

Ok, so I have this DC powered two way radio and I want to put it in my house to serve as a base. How do I convert my homes AC electric to DC power for my radio? Answer = DC Power Supplies. Check your two way radio or DC powered gear manual and/or spec sheet for DC amperage demands. For example the average 50 watt VHF radio needs 13.8 volts DC and a minimum of around 12 amps to work.
