Negative Positive
Title: Buyer beware
Review: I bought one of these for use with a Grundig radio, which needs a 4.5 v power adaptor. After a while, the radio stopped working using the power cord (it still worked when cranked up). We tested the power adaptor using a volt meter, and it was putting out 6.5 volts, even though the adaptor was on the 4.5 v setting. This probably damaged the circuit in the radio.
