Gavrilsmith Posted April 4, 2011 Share Posted April 4, 2011 An analogue radio of comparable size takes 4 AA batteries to power; a digital one, 6 large batteries which don't last that long. Does this mean that using mains electricity for digital is correspondingly a lot more expensive? Lifecell Wrinkle Cream Link to comment Share on other sites More sharing options...
jamesdean Posted April 4, 2011 Share Posted April 4, 2011 On each radio it should say on the back how many watts power they are, the higher the watts, the more power they use. Link to comment Share on other sites More sharing options...
jamesone Posted April 19, 2012 Share Posted April 19, 2012 My digital radio runs off 6Watts if it helps? Link to comment Share on other sites More sharing options...
Dataman-19 Posted December 31, 2012 Share Posted December 31, 2012 6 Watts isn't a lot. Unless it is 6 Watts at 6V (which is 1 Amp) 6 Watts at 9Volts is still .67 Amps. .. Note: 4 ea. "AA" cells, "A" Cells, "C" Cells or "D" Cells is 6 Volts. Each Cell is 1.5 volts (multiply them by the number of cells (if they are in series). If they are in parallel, then the voltage remains the same (but, 6 Watts will require about 8 cells if they are "C" cells - assuming the 6 Watts is based upon the 1.5 Volts - which requires 4 Amps of power to attain 6 watts). C cell Carbon Zinc batteries hold about 3,800 MA hr each - which is 3.8Amps hr - meaning they will power a 6-watt radio for about 15 minutes (you would need 4 in parallel to effectively have 1 hours power). ..
