I just had a 50A put into my garage and don't even know what to look for in a charging cable. Can anyone do a quick ELI5 of features I want?

There are many things to consider. If you have truly put a 50A breaker in your garage, you will have to derate this. Max output will have to be limited to 40A, not the full 48A it's capable of. That's because you have to derate to 80% of the rated output of the breaker (80% of 50A = 40A). To use this at 48A you would need a 60A breaker (and the appropriate gauge wire)
In addition, this unit is hardwire only so you would be wise to hire an electrician to install. They also have a version with NEMA 14-50 plug. If you got that version, and already had an EV rated 14-50 socket, you wouldn't need an electrician as you just mount it and plug it in. The EV rated part is important as cheap 14-50 plugs not meant for continuous, high current drain, can melt.
Finally, this is J1772. Many "older" EVs have that plug, but basically all new cars are going to come out with a NACS (Tesla) plug. If you get a NACS EV, you'll need an adapter. They're relatively cheap and is actually what I do, but in the reverse (I have a J1772 EV, but a NACS charger that I got a good deal on)

And of course, you need to worry about quality. I believe Wolfbox does have a good reputation.

I'll second most of what jasonvr said above, but for an EV charger (which have the potential to burn your house down if made poorly) I'd recommend going for more reputable one that has actually gone through the UL certification process - not one that just claims to 'meet standards'.
Also, one with a proper warranty of at least a couple years. I wouldn't expect much 'warranty support' out of this one beyond Amazon's 30 day return policy.

Some of the more favorable options include: Tesla's, Chargepoint Home Flex, and the Grizzl-E Ultimate or Mini
Here's a review 'shootout' showing some of the best: https://www.youtube.com/watch?v=sBTxLK1QC6M

It appears CSA and UL are largely equivalent with CSA being Canadian

https://control.com/technical-art...fications/

and actually this product lists the CSA US cert meaning approved for use in the US

Fair enough. Looks like this unit (E50) is also energy star certified. https://www.energystar.gov/produc...ls/3442081

That said, it does appear to have a relatively high idle power consumption @ 8.5W. Many units are below 2W, FWIW.

Our community has rated this post as helpful. If you agree, why not thank

I just returned their Level 2 Charger a couple days ago due to incompatibility with my Pacifica Hybrid and Kia Niro EV. It didnt work with either, they error out. But my existing Level 2 Emporia works fine with both, and I added a Grizzle Level 2 (using the exact same wiring as I tried with the Wolfbox) and both charge fine. I would NOT recommend Wolfbox for EV charging.

Could anyone comment on whether this is a good price ?
Looks like most of the chargers go down to this price every now and then
