Wiper Motor Power Supplies and Connectors

Hello all, I need to order a new power supply and I came across at least two different sizes. Fright Props lists their connectors at 5.5 mm x 2.1 mm and many listed on Ebay and elsewhere are listed as 5.5 mm x 2.5 mm.


So my question is will they work interchangeably? I suppose I could cut it off and attach my own female end to match.


Second question, on Ebay I see a lot of low price power supplies that seem to be designed for printers or monitors, but they are 12v 5a. Would they work on wiper motor prop?

Thanks in advance.
