I have full faith that if I were to put in a 15-50 NEMA plug at home, It'd be wired 'right'. That said, I hard wired m juicebox, and really dont need at plug.

I think my question is, are people finding that they can or cannot use the included charging system at public 15-50 NEMA outlets? Outlets that we're installed explicitly to Audi's spec?

I've tried 4 plugs now at 3 different locations and not had any luck.

I had an electrician install a 75' line and NEMA 14-50 plug at my home. My plug in JuiceBox 40 pro works fine, as well as the Audi supplied EVSE unit from that outlet. Last week I had the opportunity to use the e-tron's EVSE as a destination charger at a hotel's NEMA 14-50 plug, and it worked perfectly. I would check the wiring of your 14-50 outlet it may be improperly wired (3 wires). Other vehicles may not be as picky as the e-tron.

I tested it at at least 4 houses in the neighborhoud, didn't work in any of them. When I walked 50 meters further, to a house that was on the 400v cabine, all was fine.
As at that point my Level 2 charger also didn't work (same issue BTW), it scared the ... out of me, as at that point, I had a car waiting to be collected, but no way to charge it.
Finally, the Level 2 problem was solved by the installer, and I fixed the Level 1 problem by simply buying another cable by Zencar, which is less sensitive to the electric setup. This one does the trick (there is a grounding icon that lights up on the cable, but it works fine, and allows you to select the Amperes): https://www.4ev.be/thuislader-audi-e...eter-16a-shuko
Where do you live?

The JuiceBox 40 spec (and the Audi spec) for the plug in version is NEMA 14-50 not 15-50.

Just tried mine out and got the following results:

120V @ 100% yielded 0.8 kW read in the vehicle
240V @ 50% yielded 4.3 to 4.4 kW read in the vehicle
240V @ 100% yielded 8.7 kW read in the vehicle

My JuiceBox 40 yields 8.8 kW read in the vehicle with line voltage of 242V.

14-50 outlet, carefully self installed according to the best guidance YouTube has to offer.

You have to wonder why 120V charging is even an option - if I did the math correctly over 100 hours to charge from empty to full at 120V vs. 10 hours (overnight) at 240V.

Since I'm gone four or more days at a time, my work parking lot at the airport includes 20+ 120V outlets. Seems appropriate if the workforce parks for such a long period. Cheap to install and more than enough to allow a top up in 3 or more days.

I don't like the idea of leaving the EVSE out in an uncovered lot, but no one seems to have a better solution.

I guess they are secure since you can't unplug them without the key fob, correct? Is it OK if they get rained on?

I get the same 240V yields on my charger. Works great. I also added the wall mount. Part #8V4-915-899-A
