Hi folks. I bought an imax b6. It came with a few different cable for different charging needs. One I'm baffled for what it does. It looks to be basically a male microphone jack but with a 7/16 hex nut on it less than 1/4" from the tip making it so it can't actually plug into anything that would receive that type of charging plug like my electric beard trimmer. The nut can't be taken off as it's part of the shank that's also too large of diameter to push into female port even if it wasn't there.
