Agree with mikec in recommending the Touratech USB dual outlet. Installed one 2 years ago and it has worked great. Haven't opted for the Touratech relocation kit for the original outlet. When I want to run the Cyclepump, I use the Battery Tender SAE connecter coming off the bike's battery. Just had to swap the 3 amp fuse within the SAE cable fuse holder with a 10 amp one.
