12V power outlet

I wanted to mount the socket on my bike. The shipment was carried out, as we know it from Amazon, very quickly. Unfortunately, the outlet only very short cables (about 10 cm), so that one so could not block the outlet. This could have been avoided if the description of the article would be more accurate. Why this is ever thought me is a Rätzel. The return and refund but worked without problems.

The function I can not judge because I have as I said, not fitted socket.
