I need more power outlets (cigar lighter) too many things to plug in (GPS). My question is, what is the best, strongest, heavy duty female cigar lighter sockets. I think that I would like to mount them on the far left and right underside of the panel to clean up the Flap and Throttle area. Any advice would be appreciated
Thanks in advance

Marine stores sell them in stainless and they are vibration resistant.
