210 Watts is 17.5 amps at 12 volts
17.5 amps it the transformer out put. The draw off the AC line going into the transformer is 210 watts/120 vlots or 1.75 amps.
Now is AMPS is all you want to talk about it take more AMPS to start your car than if you turned on everything in your house at once. Your house has a 200 AMP sevice if it is like most and it can take up to 300 AMPS to start a car.
