For an electric cart ( 36 VDC to 72 VDC) and adding auxiliary equipment you need to know the capability of the 12 VDC adapter supplied with your cart. These tend to be limited, and devices like an air pump may need more power than what the 12 VDC adapter can supply.

For example a typical 36/48 VDC to 12 VDC may be capable of 10 to 15 amps. This is used to power all of the lights and any other 12 VDC equipment on the cart, adding additional load could cause the converter to become overloaded, and shutdown or fail.

Hope this helps, let me know if you have any other electrical questions. (Retired professional electrical engineer.)

Maybe the one-handed method should be discussed ?????
