As long as the charging cord is thick enough it's not a problem. The warning from Tesla goes out to prevent people charging their Model S on a el-chaepo extension cord and causing a fire.
I have successfully charged my Roadster many times with an extension cord. Occasionally even two. But they are good quality 12 guage cords. Cheap cords will cause problems.
I think I've I'm gonna charge off of NEMA 14-50 I want a larger gauge than 10 or 12. These from Amazon specifically for RV 50amp charging appear to be 6 gauge and are what I'm leaning toward for that extra length. 15' Amazon.com: Camco 55194 50 Amp 15 RV Power Grip Extension Cord: Automotive 30' Camco RV 55195 50 Amp 30 Extension Cord with Handle : Amazon.com : Automotive
Yes, the extension cords mentioned in the 1st message have NEMA 5-15 plugs and sockets and are for 120 volt charging. Good find on the NEMA 14-50 extension cords.
Thanks. I'll probably pick up the 30'. Note: I didn't see the gauge in Amazon's description, but the Q&A here agrees: Camco 55195 - Power Grip Series™ 30-Foot 50-Amp RV (Straight Blade) Cord w/ Storage Handle
How do you get Nema 14-30 adapters to fit the Tesla portable charge cord into old & new dryer outlets? They show them as available options on the TM website but when I spoke to a service advisor he said they were not available. Anyone know if such adapters are available to fit into the Camco 50 Amp extension cord?
They're coming but they're still working on building them and getting them through UL certification. I believe all they have today is 5-15 (120V), 14-50, and 6-50. So at home I swapped out my 10-30 outlet for a 6-50 and just told the car to charge at 24A. Yes, this is illegal, FlasherZ will yell at me, etc but what was I supposed to do? My options were spend a TON of money on a new panel and wiring which I don't need (24A is plenty for the amount of driving we do), charge at 120V until Tesla makes the adapter, or do the hack above.
I got mine in the other day...heavy sucker! Almost wish I'd have just gotten the 15'. I still haven't tested it to be sure it will work...maybe this evening.
Does it look the same as the pictures on the website? Or are there coloring and other manufacturing and/or packaging details? Just curious.
Looks just like the photo on Amazon...thick black cord (looks like a black garden hose) and those yellow plugs with easy grip handles. Just a web strap with a rubber handle for the carry strap.
Until you need more than 15' 30' works under 30' AND 15' but 15' does not work greater than 15' AND ONLY 15' & under! I tend to pick up more, that 15' will run out quick!
I need a quick way of building an extension cord to plug into an oven female wall plug and to the male NEMA 14-50 side of the UMC. Around 50 feet to charge my Model S. Was thinking of buying a female NEMA 14-50 wall plug and connect a 8-3 cable to it and then create a junction box to plug the male connector (don't seem to find a simple NEMA 14-50 connector in-store, just a pre-stubbed version). This is for very very very rare use. any electricical advice?
