I have old Bosch PSR12 driver/drill that all NiCA are dead. I've modified it successfully to work as Corded after removing batteries and connecting 12V 1.5A (220v) adapter. The drill works but when I push for full speed it stops, So I guess the adapter is just not enough. The Battery box has a 12V 1.2aH label on it.
What adapter should I get ? Doesnt 1.2aH equiplivent to 1A ?
