Maybe this will help.
A standard set of AA battries should give you around 450ma. Not sure but I think AAA should be around 300 to 400.
Namuna got it right. Grab a fresh set of battries. Measure just idle current. The measure charging the car. Also note voltage level doing both.
Unless that has a regulator in it, most wall/floor warts transformers consist of a step down transformer one to four diodes and a filter cap. IE they dont have constant voltage for 0 to max current and a nasty ripple. Sometimes I have seen 2 to 5 volts higher on light load. The voltage is normal what is rated when at or near the rated current.
May want to get a higher voltage and regulate it down to 3v. This will clean up the voltage and make it more like a battery.
