/diy/ - Do It Yourself

So I found an old cordless drill in my neighbors trash. The battery was corroded and there was no charger. I attached some wires and connected it to the 12v line of a computer PSU. The drill works fine, a bit slower than it should be but perfectly usable. The only problem is that at full load the PSU cuts out for 30 seconds, I assume some kind of overload protection. I guess the drill is drawing too many amps? Can I connect two PSUs in parallel to give the drill more amps?
