Your typical Level 1 / Level 2 home EVSE (i.e., charging station) can typically be plugged into a NEMA 5-15 (your average 120V outlet), NEMA 6-20 (240V outlet, not nearly as commonplace in your average home vs. NEMA 5-15), NEMA 14-30 (240V, typically used to plug electric dryers into), or NEMA 14-50 (240V, typically used for electric ovens and RVs) plug outlets, depending on the type of plug that comes with the EVSE--many portable (not to be confused with wall mounted home EVSEs like the Tesla one mentioned in this thread) Level 1 / Level 2 EVSEs include an adapter to plug it into a NEMA 5-15 receptacle.
As noted above a NEMA 5-15 is rated at 120V whereas the other ones I mentioned are rated at 240V; NEMA 5-15 outlets are typically wired to either 15A or 20A circuit breakers (for the latter, a 5-15 plug outlet rated at 20A must be used), NEMA 14-30 outlets need to be wired to a minimum 30A breaker, and NEMA 14-50 must be wired to a minimum 50A breaker.
It should also be pointed out that if choosing to run wire from a 60A breaker the wire gauge used here is somewhat thicker than that used to run wire from a 50A breaker--meaning, more expensive per foot; you many want to keep that in mind if you don't have a 60A breaker already in place and are looking to have one installed. Do not try to be cheap and cheat your way around it--electrical code requires it plus it's not worth the risk of potentially having your home burn down. If looking to power a home EVSE off a 60A circuit it is highly recommended to hardwire said EVSE to the 60A circuit rather than plugging it into a receptacle capable of handling 60A.
As far as current draw itself goes--electrical code requires that the max current draw cannot exceed 80% of the circuit breaker's rating--meaning, for a 60A breaker the max draw is 48A, 50A breaker is 40A, 30A breaker is 24A, 20A breaker is 16A, and 15A breaker is 12A. What does this mean in terms of power draw? Given that W(atts) = V(olts) * A(mps), and the voltage rating of the various NEMA plugs I mentioned above, you get this (and yes I realize this is explained on the Tesla wall connector product page as well):
NEMA 5-15 -> 120V * 12A = 1.44 kW
NEMA 6-20 -> 240V * 16A = 3.84 kW
NEMA 14-30 -> 240V * 24A = 5.76 kW
NEMA 14-50 -> 240V * 40A = 9.6 kW
NEMA 60A -> 240V * 48A = 11.52 kW
It should be pointed out that currently there aren't that many EV models that can charge at rates higher than 11 kW so unless your home already has a 60A breaker (and an outlet wired into the 60A circuit) already in place and/or you have a Tesla and really need the Tesla wall charger's 48A capabilities it makes little sense to spend money to have one installed. Your typical public charging stations are capable of charging at much higher kW rates because they use DC charging vs. AC charging (which is applicable to the stuff I mentioned above).
I'm not gonna debate as to whether one really needs to charge at higher rates when charging at home and/or its effects on long-term battery health, just simply throwing out the raw numbers here for those wondering about charging times; you can do the math by looking at the various power draws I listed above and knowing the battery capacity of your EV in order to then determine how long it will take to charge your vehicle based on your EVSE's capabilities and home electrical setup.
Every other modern Tesla can charge at 48 amps, which the Wall Connector can supply.
A mobile connector + 14-50 adapter costs $320 anyways, this isn't much more unless you're okay not carrying the mobile connector.

The NEMA 14-50 doesn't list miles per hour, that I can find. But both list 15%-100% charge time. 20hrs vs 8 hrs.
That ratio gives us 2.5, and then the amps 30:80 gives us 2.666. So you're right it's not as efficient, but doesn't seem egregious and makes sense because there's usually a bell curve to efficient charging. I'd imagine the "rounding" they're using for the marketing may make things look different, and both may need a slower top off cycle.
I was curious if there's another charger people are looking at that in the 60-60+ amp charging options, ignoring cost and efficiency and looking more at faster charging.
More than once, I've gone on a long road trip on a Saturday, gotten home close to midnight under 10% charge, then had the car back to 100% by 8am for another road trip on Sunday. At 32 amps, I'd be waiting until noon to leave or topping off at a supercharger unnecessarily.
Also, if you decide to add a second electric vehicle that's not a Tesla, you can just use that.
You can also charge a second non-Tesla with a Tesla->J1772 adapter: https://www.amazon.com/Lectron-Te...B07V7V2QT8
Significantly bulkier than the J1772->Tesla but it's an option.
If you have a local utility incentive on a non-Tesla EVSE though, that's a no brainer.
To your point, all other EV manufacturers are putting CCS1 on their vehicles sold in the US, so eventually it will become ubiquitous. The 3rd-party charging networks have a loooong way to go to catch up to Tesla's supercharging network. I give it 10 yrs til non-Tesla owners are able to make cross-country trips as conveniently as Tesla supports.

Like wrong gauged wiring / breaker ....
The NEMA 14-50 will get you 32amps, 7.6kW (220V).
So there is a difference, worth it? Up to you, how fast you want to charge. Needless to say if you don't already have the 14-50 outlet installed, then go with the Tesla WC.
Too bad they don't have the original capability of charging @ 80amps.
As a concrete example, I picked up a used 2013 Model S for $27k. Gorgeous car, spent maybe $800 to fix a few things on it (4G LTE upgrade, screen UV treatment, etc). It doesn't have the range of newer Teslas (265 mi vs ~340), but it does the job. I drove it 900 mi from point of purchase to home and the supercharging experience was excellent. I spent 30 min to charge, but I needed to stretch my legs, goto the restroom, and get a snack anyway so not much time lost.
People complain about gas prices but continue to buy gas guzzlers. Make smarter purchasing decisions.

Here's the math/quote i've received in the past:
Labor : ("I'm installing a charger for my tesla") $1200
Tesla charger : $500
__________________
Total : $1700
vs
Labor: ("I need a NEMA 14-50 for my dryer) : $375
__________________
Total : $375
I kid you not, these were the prices. This "tesla tax" for all you new tesla owner is going to be a "nice" surprise. It's there when you try to get your windows tinted as well.
