Laptop power supplies, does current matter?
Can I use a power adapter with more current but lower voltage on another laptop?
I have an ASUS K50IN laptop which requires an input of 19V at 3.42A. Its charger has stopped working [wires cut by rats!]. My brother have a charger that is 19V, 7.1A. Their polarity is the same and the tip fits correctly.. Can I use this charger on my laptop?
