Solve : Power supply!?

1.	Solve : Power supply!?
Answer» Is It safe to use a 18V 3A instead of !8V 1.9 A fo my laptop? Thank you. Should be fine if it fits. The thing that really matters is the voltage and they are both 18V so it should be OK. The fact that it's 3A just allows it to draw more POWER if it NEEDS it.
