It
sounds OK. I mean, as long as it's not
my router.
Seriously, I would think that 1.2 is the max that it
can deliver, but the amount that actually gets drawn depends on the voltage (which is exactly correct) and the impedance of the router. If the router's designed to take 12 V and draw no more than 1 A current, hooking it up to a source that can provide 1.2 A should make no difference at all. I think.
Unless the difference in ratings reflects a difference in internal resistance. The 1.2 A source might have less internal resistance, which translates into less "protection" for your router.
Hm,
you should probably wait for info from someone who knows more about what those ratings actually mean.
