myVolts Ripcord 12V DC

I've tried other MyVolts plug before for my Volcas which have been great but this one doesn't work at all and I'm afraid it could damage synths through incorrect voltage or amps.

I've tried it on multiple different instruments listed to no avail such as the Crave, Model D and Reface. Either mine is faulty or it can't supply the power it says it does. I've used it with different power sources but no dice. Would avise avoiding

I bought this cable to use it with my Digitone, I must say that it works sometimes yes, sometimes not. I do not recommend it. I prefer to buy an external battery to use with its original power supply.
