  • Common Questions


    Will it work with digitech rp 500?


    The unit doesn't work for effects that require a Boss type 9V DC adapter as the polarity is the opposite of what those effects require.


    What's the current rating?


    It's compatible with 9V (100mA - 1500mA)


    Would this work on a Dc9V-200mA item?


    It will supply that much amperage.


    Will it work for a stationary exercise bike?


    It will work if the current draw of the bicycle is less than 1.5 amperes.


    Will this be enough to power my brookstone handheld massager item no. F-451 Sku #317860?


    If your massager is 9v with center +, it should work.
