TeslaTap 50 AMP is enough?
I almost bought the Lectron but saw reviews on YouTube where it frequently failed to work on some cars like Hyundai/Kia/Genesis. There was even a video where they opened a TeslaTap and apparently there's a little circuit board in there that negotiates with the charger as opposed to the Lectron that only had some resistors. The MINI is just stoopid expensive though, almost as much as my Splitvolt charger, so I guess what I need is this 50 AMP one: http://www.umc-j1772.com/index.php?r...&product_id=99
EQE maxes out at 9.6kW / 240V = 40 AMP and it's my understanding electrical codes say for continuous use you should only pull 80% so I'd need a 50 AMP adapter to be safe, right? Seems there's a little confusion in the forums about Tesla destination charger ability to provide up to 80 AMPs. Correct me if I'm wrong though.

I am guessing that the adapter is sized to support 50 amps continuous so it would be oversized for your 40 amp application

Yeah, that's how I read it too:
But I'd rather err on the side of caution and get a slightly bigger conductor whose resistance won't increase as much as temp goes up.
We do not list all of the vehicles that are compatible as our bypass circuit makes the TeslaTap 40 compatible with ALL US built EV’s with a charge rate up to 40 AMPS @ 250VAC (10 KW).

Maybe someone at TeslaTap read this thread. 
The wording has changed:
So I believe their 50 AMP adapter should allow my U.S. spec EQE to pull the max 9.6 kW (40 AMPS @ 240V) continuously and safely. They haven't changed the wording on that page yet tho.

Just went from my Tesla To an EQE suv. Went to Amazon to get an adapter and found this 48 amp Fizzenergi for $50. Hate to be cheep, but it's around $150 less than some others. Anyone with any experience with one of these?
thanks
thanks

Not sure about the quality on those, could be just fine. I went with a Lectron one based on its ratings and purported ampacity of the conductors. Ideally, you want to minimize resistance in those conductors to prevent heating. Probably not worth risking an $80k+ car on a $50 adapter, but hey, if it works, it works. Just observe, take temperatures, and proceed with caution. It may be totally fine.
