[Shop-talk] 12 volt benchtop power supply?

[Jim Franklin]

I'm debugging some trailer wiring and would really like to have a 12v  
power source that could handle 6 bulb's worth of current, rather than  
leaving the trailer plugged into the car, or having a battery on the  
benchtop with a charger. Is there such a beast? I'm finding lots of  
super pricy clean power devices but all I need is a $20 black box.

thanks,
jim
