Read the info on the adapter. It will tell you whether it puts out AC or DC. If the info is missing --don't use unless you can check it with a VOM meter!

The trolley uses a 7.5 volt power supply. If you are like me, I have accumulated many similar power supply adapters over the years. Check the voltage on the adapter to see if it is 7.5 to 9 volts and will plug into the shed! I fit does it will probably work. I upgraded mine from the original power supply to a 9 volt power supply to give the trolley a bit more speed!
