I got a short extension cord to change how I plug in my FXS. I know it's not a big deal, but it's always felt like a hassle to feel around or bend over and look up to see where the port plug is, pull it out, and plug in the cord. The next morning, I would pull out the cord and bend over to put the port plug back in. If I was feeling thorough, I would unplug from the wall first before plugging/unplugging the bike to avoid any possible arcing. Once in a while, I'd notice the port plug was out after a ride. Either I forgot to put it in, or didn't put it in straight and it fell out. To avoid all this, I am using a 2 foot C14-C13 cord. Now I can plug in standing and looking down. I also don't worry about unplugging from the wall first, since I can more easily replace the 2 foot cord than the charge port.
It's still mostly a two handed operation since the female end of the cord just kind of sticks out from under the seat. I'd like to figure out a good location that I can anchor it down and plug in one handed. For me, it's the little things in life.
