I googled the model and found one site that reports power consumption for the air conditioner as 250 watts, a little over 2 amps. I think there is little chance you'll overload anything.

I'd be curious to know more about what it's doing to disipate heat. My first impression is that it may blow cooled air in one direction but not offer real cooling of the space it's in.
