This may seem a strange request, but I think you need a different wall–wart PSU. The one that came with my vero has a cable that is much too short to reach from the power socket to where the vero needs to sit. I’m using another PSU that I already had to work round this.
Some people might say that you need your power socket in a different location and the wall-wart is fine.

How long do you need it?
My Pi PS is 1.5m and it uses a 1.5m HDMI cable. I’ve never thought ‘Hmm that’s too short’ with those, in a variety of setups. If only one was made longer, I’d opt for the PS.
