HPWC and SR+

[eprosenx]

Is there any benefit getting a HPWC if the on board charger max out at 32 Amp with a NEMA 14-50? I originally thought the HPWC would allow me to charge the car at 48amp if I have a 60amp breaker, but someone told me SR+ only charge at 32 amp from either the UMC or HPWC. I am so confused.

We discuss these same topics on the forum here so often that I put together a couple of pages that cover a ton of the pros and cons that are being discussed here (great discussion and points by the way!)

It comes down to personal preference. I myself installed a Wall Connector outside and a 14-50 inside (as a backup), but that was just me.

Slightly off topic, but does anyone knows if you can plug an HPWC to an existing NEMA 14-50 plug using a cable similar to this? https://www.amazon.ca/Conntek-Outdoor-50-Amp-250-Volt-50-Feet/dp/B001TO4YH6/

Long story short, I would prefer to use the HPWC over the mobile connector for aesthetic and logistical reasons (outdoor parking).

I believe the answer is yes but it is technically a code violation.

Yes you can, but it's not really meant for portable use. Besides the size of the body, the cord is going to be heavy and awkward. Personally, I'd stick with the UMC, and if you just HAVE to have 40a, the corded mobile connector.
