Length of mobile charger

Can someone kindly measure the mobile charging cable from the end of the charger unit to the plug. Thanks

From watching those state of charge videos, the adapters are only a bit more than a foot so not much more from the 20' mentioned above.

This brings up another question for me. It is better to buy an NEMA 14-50 extension cord or a J1772 extension cord?
Extension cords of any type are not recommended, but I have never seen or heard of a j-1772 extension cord..?
I've already found a nema 14-50 cord that should be safe. See:

I have not researched this one like above, but here is a J1772 extension cord:

That's awesome, thank you for posting that. A weapon to fight back against icing.😎👍👍
For me, I have parents and in-laws with their dryer outlets near their garages; hoping to park in their garage, and charge on their dryer outlet using something like this.... :)
Yeah, whereas EV and evse makers will say extension cords not recommended, 1450 extension cords are used with RVs all the time with no issues, and I have used them successfully over the years. I think the caveat is mostly because the manufacturer can't control what people do with extension cords, and sometimes people do some pretty silly things.

I'm coming from many years in the RVing world too, and still own 3 campers, us and two of our boys at college on their own RV lots. Our former motorhome was 50amp 240v and our current campers are all 30amp 120v.

This is where the fun begins: when you have a 50amp motorhome, with two roof air conditioners on 20amp breakers for each, a large Inverter/Charger, and all the interior amenities, a microwave especially. We learned over a very short period of traveling that having MANY different adapters and extension cords was key, when a 50amp outlet was not available.

Although, I'll admit that even now I realize that EV charging is different. The main change is that motorhomes don't necessarily pull 50amps on both legs of 240v power at the same time Continuously, or rarely do, if ever, but the mobile EVSE does draw continuously, at least at 30amps. The heat generated in the wiring can certainly be more pronounced and prolonged, and therefore would make one more cautious to the extensive use of 'extension cords' and additional in-line junction boxes and female and male plugs. Of course, there are times when it makes sense, I'll use one at one of my son's camper sites since I won't be able to park close enough for the EVSE cord to reach, but that's not a long-term solution.

I think Ford is smart to use the NEMA 14-50 as the go-to outlet. It is designed for 50amp 240v service, and designed to 6/3AWG wiring, suitable for 50amps of continuous load. While the EVSE will only be close to 30amps on each leg, this gives breathing room for the heat to dissipate easily and never be a concern.
In another situation, I might use an existing 30amp double-pole breaker in a pinch, or for a temporary solution via an existing DRYER outlet. It's also not a long-term thing, though it make work just fine, especially if the outside temps are not already adding to the wiring's own ambient temperature.
Ford is just using the 14-50 because it was established as a defacto mobile approved connector in legal battles Tesla waged a number of years ago.

It's been too long since I read the findings, but government regulators refuse to allow connections above 110 volts because they were not approved for "mobile vehicle" use. Tesla went to war in court arguing that a recreational vehicle was by definition a mobile vehicle, so the 1450 should be allowed for their early EVSEs. Tesla won, and here all these years later it is the OEM de facto standard. Another way Tesla paved the way for all of us.
