Its probably safe to assume that this thing isn't using much current.
How long does the battery last?
Using a 1.5V DC power supply, rated at least at 100mA, is likely to
satisfy your needs completely.
I would recommend you to check the wall wart with digital voltmeter
before you use it. It might be putting out more than 1.5V.
Wall warts are, usually, cheap and low quality crap so you have to be a little
carefull with them.
What is inside this little gadget of yours? Just motors? Any electronics?
