Is it safe to charge an Acer netbook rated for 19V DC and 1.58 Amps with an Asus laptop charger that outputs 19V DC and 4.74 Amps? I think so, but I just want to check.

Yes, as long as you can get the connectors to match (including the polarity). Amps is the maximum power that charger can output, if the laptop requires less power, it will draw less power.

Thought so. What's the polarity mean, though?

On your laptop, as well as on the charger, there will be a symbol, kinda like this:

Make sure the + and - symbol locations match on both laptop and charger. Polarity itself refers to flow of current. Like on batteries - you have to put them in a certain way, otherwise your device won't work and may even be damaged.

Ah, okay. Cool, thanks.
