70 Watts divided by 12 Volts is 5.83 Amps.

Instead of a power supply, you might want to get another car battery. 
At a draw of 6 Amps, the battery should last a while.  Then, swap it 
with the one in your car to recharge.

You also have a hot spare in case you leave you car lights on one day.  :-)
