We love the Pachy. It is quiet and smooth and doesn't feel like it has any power penalty versus the Town & Country we traded in. My family has a
dealership in another state where we bought. There is now a state rebate on these, but we are not eligible since we didn't buy it from a Texas dealer.
I picked the VersiCharge because it is simple and has integrated cord management. We have a flat rate electric plan so there is no benefit to scheduled charging, and it is convenient to hang the cable over the charger and plug it into the dummy socket on the front.
I am not sure if 10 AWG will cut it for a 50 amp circuit through the attic. You might need to dial back the amperage on the charger and use a smaller breaker. It would still be much faster than the L1 charger in a 110v outlet. Your electrician should know for sure.
