Need Some Electrical Expertice

[FCIN]

Sorry to ask silly questions but here goes anyway. I need an inexpensive 120v AC to 12-14v DC transformer to power an Aristo-Craft Radio Control Throttle. I saw one at the local Radio Shack that said on the box that it was 120v AC to 14v DC 5000mA. Am I correct that 5000mA = 5 Amps? Just want to be sure that the output is 1 Amp or higher before I plunk down my $28 for this transformer.

Thanks!
