If i were installing a new one right now, I would get a Chargepoint hard wired one. They are rated so highly by folks I trust, e.g., such as Tom McLoughney @ StateOfCharge. And still inspite of Porsche sale pricing, the Charepoint is $450 less.
_ONE_ (not all) of the issues w/Porsche is their ability to support their EVSE products…if you have any problems with a Porsche EVSE they are mostly incapable of providing any meaningful support for their products - for example when this unit can't charge a non-Porsche EV and you raise that issue to Porsche (who I've never really figured out) they will have no response or follow up.
but as long as it's working it's a good choice, especially for a 100 amp 19.2 kW model (which this one _CAN_ do) is a good price for an EVSE like this.
My utility has a $300 rebate for the ChargePoint unit, and I can use it for their Flex program that pays $50 for signing up (the utility gets to stop charging if they need, which they pay for, to balance grid load a few times a year)
Good point craz8, that we all should first check with our electric utility. Mine offers $250 off for new EVSE install (either a direct check to the customer or a bill credit).
