So, I got the Lectron Tesla to J1772 adapter (48A) version. I got a smoking deal on it.

Anyway, I am noticing that it works 100% of the time on the Gen 2 Tesla Wall Connectors. So far I have only been able to use it on chargers that are 40amps or lower. It gets warm, but no different from any other charger handle at 40A.

I was the lone Mach-e with the Teslas at a hotel sipping on free electrons. The hotel has J1772 chargers but they are 20A and they charge for those.

But I am noticing that it does not work 100% of the time with Gen 3 Tesla Wall Connectors. My company has 8 x Gen3 Tesla wall changers that they claim are all set-up the same way (haven't convinced them yet to let me play with the settings). Anyway, The Lectron works with 2 out of the 8. I am wonder if the Gen 3 has more app lockout to keep adapters or non-tesla connections from work. But that would mean Tesla Tap should have the same issues.

Is anyone with a Tesla-Tap noticing connection issues with Gen 3 Tesla Wall Connectors?

Gen 3 Wall Connectors have a feature that allows the owner to restrict them to only work with Teslas. I haven't heard if Tesla has enabled that feature yet, but it's possible.

The biggest problem you may run into with the Gen 3 chargers is they can go up to 80A. Since the Mach E can charge at up to 48A, your smokin' deal may be smokin'.

Yes, it would request 48A. On a 40A adapter, that could be pretty uggy. 😱🐩
Yep. That's the reason we're getting at least 50A and typically the recommended 60A or higher TeslaTaps for the Mach Es.

Yes, the MME won't draw more than 48A. So as long as the Lectron is rated for 48A of continuous use, it would be fine.
I e-mailed Lectron during the Tesla Tap discount period asking if their adaptor was rated for 48A continuous use and they said that it is.

It probably is. People get hung up on the 80% rule for continuous use, but that is specific to NEC code in buildings. The same doesn't necessarily apply to external devices and adapters. Those just go by the manufacturer's ratings.

I agree. Nice to get it in writing from the manufacturer though. 😁 :cool:

Right. External devices tend to have more air movement around them so the thermal build up is not as high. I would still prefer to use an adaptor rated for something higher than what the car is going to request than one that is under-rated. 😊🐩

And it is a bad sign that the device gets warm at 40 Amps.

I used my TeslaTap Mini 60 amp at two different hotels and it worked perfectly both times.

Plug the TeslaTap adaptor onto the Tesla cable. Wait 30-40 seconds. Plug into MME. Charging!!

When I say warm...I mean warm...not hot. Like the same temp as the Tesla handle or any J1772 handle would. It was 50F ambient when I checked it so it was probably only 80F.
