NEMA 10-30 receptacle + Tesla mobile charger with 10-30 plug+ NACS to J1772 adapter questions...

[Taki]

Hi, I will be picking up my 2025 Mach-E next week (coming from a Model Y) and am trying to get up to speed on ways to charge the Mach E using my current Tesla mobile charger (which is connected to a NEMA 10-30 receptacle using the Tesla mobile charger 10-30 plug and in my garage). It seems simple enough to just purchase a quality NACS to J1772 adapter and I should be good to go, however, I came across this link which explicitly says, "Level 2 Adapter Compatible Adapter, but Ford does not approve." It says this in the top blue box which is on page 2 of the PDF in the link below:

Ultimately my questions are as follows:

1. Is it a problem using an NACS to J1772 adapter and a Tesla mobile charger on a 10-30 receptacle? I believe the Tesla mobile charger with 10-30 plug will limit the charging to 24 amps so that it is 80% of the 30 amp breaker. I would probably get the UL 2552 approved A2Z NACS to J1772 plug adapter. I don't like the language that Ford does not approve of a Level 2 adapter in the link above.

2. On a Model Y, the car automatically adjusts for the inputted amps. Does a 2025 Mach-E do the same, or do I have to set it every time I charge?

3. This approach seems to be the cheapest way for me to Level 2 charge at home (all I have to do is buy the adapter). Does anybody else have a similar setup or do something differently?

4. Can I just leave the adapter plugged onto the end of the NACS cable all the time, or do I have to remove the adapter from the cable every time I unplug the car?

5. Is there anything I need to do in the Ford app for charging at home as described above, or is it just a matter of plugging it in like on a Tesla?

Thanks, and I appreciate any input!

1) Not a problem. Get the Stellar adapter. Currently 15% flash sale, was 25% for Boxing Day, but that ended. Stellar Pro is unnecessary. https://a2zev.com/products/nacs-j1772-stellar?ref=Typhoon

2) The vehicle will take up to 48amps via AC charging. Nothing to do.

3) Yes, many. May have to set the charger from "Tesla Only".

4) Leave it.

5) You need to set, ideally in the vehicle, the charging location (after you charge for a minute or so) for the max charge level and hours you want to charge.

I bought a Tesla Mobile Connector for use at my friend's duck hunting club because they only had 10-30 and 5-15 receptacles available. I used it several times with a Lectron 80A Tesla Destination Adapter (that I already had) with no problems.

As long as you’re using the Tesla 10-30 plug and not a 14-50 to 10-30 adapter, then you’ll be fine.

As for the Tesla to J-1772 adapter — just use a name-brand one. I use a Lectron one, and it has been working perfectly for years. I originally used it with my Bolt, and now the Mach-E. The only time you have to worry is with higher amperage charging. Some adapters are only made for up to 40 or 48 amps. Of course, the Mach-E maxes out at 48 amps, but you want to check on the adapter just to be sure. Any of them will work at the 24 amps you’ll be using, but you might take it with you on a road trip, and you want to make sure it’s good for at least 48 amps.

Check the version of the Tesla Mobile adapter. If it is recent, it should be fine. I believe Gen3 supports J1772, but previous generations did not.

I have a Gen 1 I use all the time with a Stellar adapter, the Tesla Mobile Connectors communicate just fine with J1772

I thought of another question. When I am charging with the Tesla mobile charger and I am ready to remove the chargong plug, do I need to push any buttons on the tesla plug or the button next to the car charging port? I still don't have my car yet...

Any adapter worth a damn should stop the charging when you press the release handle. No need to press the button on the Tesla handle or anything else.

Simply press the release button on your adapter. That will signal to the car to stop charging. Wait a quarter of a second or so, then pull the adapter from the car. You can then remove the adapter from the EVSE or leave it connected to the EVSE.

All adapters should stop charging since the act of releasing the latch from the car tells the car to stop charging.
