    I am thinking of installing one of these retractable cord reels in my garage. Either from the ceiling or wall.

    Has anyone installed one? Or researched one?

    I have Cox Reels electrical and pneumatic hose reels in my workshop. I have it setup for less for 120v at 15A. Not sure if they'd be rated for 230v and what specific amperage. The mechanism that allows for the reels to move seems a bit iffy for high amperage use and arcing. In my case the Cox reel has a copper hub and spring loaded arc shaped copper "brake" that applies pressure to hub while allowing it to rotate freely while passing current.

    Depending on the length of cable, you'll have to upsize as cables will heat up more so as they are coiled versus uncoiled.

    Roadster folks have done something similar. It's better not to have the cord coiled up. Perhaps just a counterweight system that keeps most of the cord out of the way.

    The Model S cable is so much thinner and lighter doing something like this picture above should be much easier too.

    I currently have a dual counterweight system for my two chargers. I will need to add a third one upon arrival of the Model S. Roadster connector is retracted next to right door opener.

    I'd be very careful that the cable does not overheat. When you're running a cable at full power it needs a way to dissipate the heat generated, and coiling it up would significantly hinder that.

    Just realized, the retractable coil wouldn't work unless you cut your UMC cable after the electronics box and spliced the cable through the hose reel. Either that or you'll have to make a very short UMC cable attached to the hose reel.

    The counterweight seems to be the best bet.

    I'm definitely going to setup something like donauker has, but I need to see how long the cable is before I do it since I'm not sure how much room I have to play. My intent was a pulley type system that holds the charging cable. Sort of like these, put a couple on either side of the garage door to arch the cable from the wall well over the car (but below the garage door rails).

    When I start getting set up for my X I'll do something similar, although I do think the coiled systems are a bit questionable due to heating. I plan on keeping it as open as possible and sized so it can't get down to the floor.

    That retracting reel CKessel shows looks interesting, where did you get it?

    Googling for "retractable garage pulley" or some such :) I haven't bought it, but it's the sort of thing I had in mind.

    Try searching for the term 'tool balancer'.

    I am using a retractable wire reel that is used for medical gas hosing. Once finished, I will post glossies.

    Great feedback from everyone. Thanks. I found a reel that supports up to 55 amps but I think I like the counter weight/pulley option better. I will start searching for options and post info when I find out more.

    That is the one I found too. It is very pricey. Also, based on heat issues due to coiling and need for conversion of plugs, I am leaning towards using a tool balancer as others have suggested. Here is a Google shopping search I used: tool balancer - Google Search

    My plan is to walk into Home Depot or Lowes and describe what I'm looking for and let them lead me to it :)

    K let me know which one you guys get! I'm not sure I can hang anything from my ceiling though because my heater vent runs above the nema outlet

    You can always come up some sort of wall mounted boom arm if you can't ceiling mount for whatever reason. In fact if you create an articulating or swivel boom arm you could potentially charge in either direction (parking head first or backing into the garage).

    Sample idea only:

    The tool balancer looks like a good approach. I may go for simpler but much less elegant solution and install a hose rack on the wall of my garage to store/wrap the charging cable when not in use, such as the one shown in the link below:
