Power supply

I have taken my RBR20 out of storage and can't identify the power supply. 
the manual says 12V-1.5 A.  I have found a 12V-3.0 A power supply. Can I use this one?

    You can use higher amperage power supplies but the voltage and polarity need to be the same.

      I am not sure what you mean by polarity? Can I sent a photo of what I have?

      via text? Need your number.

        The (+) plus and (-) minus symbols on the plug connector need to be the same as what is one the stock power adapter plug that goes into the back of the RBR/RBS unit. Most cases the center of the plug is always (+) and the out side portion that you see mostly is (-). Look at the power adapters sticker to see the configuration printed on it.
