Anyone made an adapter for the power cord that works?

With limited adapters available from Tesla (5-15, 14-50 and 6-50 are the only ones I know of available at this time), had anyone made a home made adapter that works?

Today I tried to use something an RV buddy of mine has, which supposedly links two 5-15 outlets (usual US houses) to obtain 240 voltage (which theoretically would half the charge time using a standard 120 volt household outlet).

Here is a link:

Needless to say it didn't work. The Tesla cord had a red light on it instead of green.

I was also interested in this:

However to use this one would need some form of adapter from 14-50 or 6-50 to a 6-15.

I'm just not sure whether the tesla cord can recognize these adapters or extension cords and "shut down" but there needs to be some other ways for us to charge this vehicle than public stations. And the power cord won't reach a dryer deep in a house.

Thoughts?

I really think you'd be better off installing a supported outlet in your garage, or wherever you plan to park your vehicle. I would rather not try to "hack" a solution for such an expensive purchase.

I don't think I understand the situation. Do you not have a garage or driveway? I know renters are sometimes having difficulty. Why would you need to jury-rig something for home charging?

Can't you just have someone install a 14-50 near the car? These adapters you are looking at are over a hundred dollars each. By the time you buy them it might have been cheaper to install the proper 14-50.

I have a 14-50 in my garage. Charges just fine. I live in Tennessee where public charging stations are not as prevalent as the west coast. Many other EV owners including Roadster owners made their own adapters for traveling situations where they may stay at a friend's house, hotel, etc. I'm looking for solutions for these situations.

Getting a 240V outlet from two 120V outlets (whether home-made or using the Quick220) only works if the two outlets are on different sides of the split-phase power (your house gets 240V with the ground/neutral in the middle, so either hot wire is 120V above ground; some houses get 2 out of 3 phases that give 208V across them). Quick220 automatically detects when they are on the same phase, but otherwise doesn't do anything special, it just gives you 240V between the two hot lines.

Neither of these approaches will work if either breaker is a GFI or arc-fault breaker, as the current won't be coming back through the neutral connection. This is also dangerous to do if you have any 120V connections, since you can overload the neutral of one of the outlets.

If all you want is an adapter to use other outlets, you can wait a few weeks and buy them from Tesla, or you can make a cable to connect to a NEMA 14-30 and then program the car to draw 24A since by default it will think it can draw 40A, since it sees the 14-50 adapter.
