Do I need purchase HPWC online in advance ?

Why do people bother with these rather than just getting a 14-50 receptacle installed in their garage etc? The car comes with a big charging cord and various plugs (interchangeable) including a nema 14-50.

Just curious. Installation costs will be similar but the hardware costs of installing a receptacle will be a fraction of buying a $600 HPWC.

I bothered because I didn't want to have to get the cable out of the car each day (I want to make sure my travel cable is always with the car), and the connector is easier to insert, and has higher current carrying capacity (not really needed in most cases).

And it looks cool... :)

Each to their own....but those are my reasons.

I’ve had an S and now X for over five years now, and those were my reasons for putting an HPWC in the garage: faster charging (80a on my S and 72a on my X vs 40a), no risk of forgetting the cable (always want to have it in the car for emergencies), and less hassle as well as safer to not be constantly plugging and unplugging a 240v plug, especially if one of my kids does it.

HPWC looks cool plus AFAIK the handle is not energized until it does a handshake with the car prior to starting to charge, so much safer to handle.

That said, when we installed solar I added a NEMA 14-50 outlet in the driveway, to have a backup charging location. Glad I did because we will soon have an AWD Model 3 join our X.

Update: just got out my multimeter to check. It measured 0.1 volts at the HPWC handle’s power points.

In Ontsrio, you get half the purchase price back as a rebale, so only $300

It definitely looks better.

It's not easier to insert it's the same.

It's good for higher power but not necessary as you say.

But why would you have to get the cable 'out of the car each day'. Keeping it in the car always doesn't make sense. Unless you went somewhere super remote away from home for a while where you had to plug into 110 to charge.

Personally I have only used my cable 1x away from home in 30,000 kms of ownership. It lives in the garage.

Superchargers and level 2 chargers have their own cables.
