I use an EV-ject every time I charge and so does my wife. it does help a little with angle and reach.

Almost very supercharger i frequent now has at least one. It’s a regular spot except instead of the charger being at the back of the spot it’s right across from the charge port when parked. Something like this you pull into forwards.

Good point. I have seen the one special stall. I was thinking more of Euro? style where all the stalls have side chargers.

Maybe EVJect would work for reach, but then you're daisy-chaining adapters which is generally a no-no.
Each of them are simply pass throughs, which lessens the issue. Any decently made CCS to NACS adapter won't have any issue at 500 amps and neither will EVJect. Now there are a lot of bad adapters out there flooding Amazon and Alibaba... but I'd hope Applegreen didn't utilize a bad one. The other alternative is the A2Z Cybertruck adapter, which is a really well made unit.

The whole issue with the extension cord isn't the handle... it is the cable. A 400 amp cable simply isn't robust enough for the draw that Tesla requires (or most new EVs).

Agreed. I wonder if passive cooling air-cooled extension cables can really become a thing with the higher amperage charging since it seems liquid-cooling is almost mandatory in these cases to safely avoid heat build-up and derating. Especially in warmer climates.

There should be some signal from the charging handle to the adapter/extension cable back and forth that limits charging to 100-150kw (or whatever is deemed safe) if an accessory is detected to be in use. Sure, that sucks for peak charging speeds, but if someone can then safely use an accessory when needed for extra reach so be it, wait the extra 5 minutes for your charging session.

yep if you own a CT in the NJ area, you need an A2Z ccs to nacs adapter or one with a similar extended nacs side. the nacs applegreen chargers on the turnpike do NOT work on CTs.

if you have something mounted in the hitch like a bike rack, or shelf or spare tire, etc - unless th SCs are arranged so that the thing in the hitch fits between them like this:

and there are definitely some that wont allow for this, then you either have to wait for a pull into/through slot or take up a bunch of spots, or demount your hitch jawn.

and then theres the rest of the world that now able to use our charging infrastructure - their ports are all over the place.

an extension although presently unsafe will be useful for those cases. or maybe they can just lenghten all the cords - which yeah youmight have heat issues still.

Tesla's solution is simply V4 cabinets. They won't retrofit V3s with longer cables (some technical cooling issues) and the V4s just have longer cables attached. Though they won't be long enough for every situation still.

right so I agree with @carsly have the whatever product it is talk to the supercharger to say “yo, easy with the electrons, we dont want to melt/burn/explode” and watch 6 youtube vids instead of 3.

With NACS being a published standard, it is certainly possible to do this. The communication isn't overly complicated.

How many of you have been to a supercharger where it wasn’t possible to plug in the CT? Where? What configuration? Please share.
I keep hearing how badly needed this thing is every time some iteration of this thread shows up every several months but why?
My personal experience as someone with free supercharging who uses them an awful lot has been that with smart parking towards the left of the spot and carefully backing close to the charger this is never the case. There are instances where you’re too close to open the tailgate but none I’ve seen where I could not charge. Trailer spots and side chargers are even easier
Those of us who tow an RV are one example of an extension market...scarcity of "pull-through" charging stations means we have to find a place to unhitch, go charge, re-hitch. If an extension were safe and feasible, many times charging stations are available from opposite side of normal parking space, and relieves the hitch-unhitch routine. I'm aware of the non-feasibility/safety of current extension status, but if this changes I'd be a customer.

These EV charging handles and chords are very expensive, and there are exactly "0" approved extension cables. It's a direct violation to use one on Tesla's network.

If you burn your truck to slag and end up taking hundreds of thousands of dollars in equipment with you, the losing parties are going to sue you into oblivion.

People need to know and respect how much juice is flowing through those cables into your vehicle.

It’s not always I dream I have Deja Vu, but when I do, it’s like it’s happened before.

as has been said many times. “yep.” I dont want one that is zero approved. the company doesnt appear to want to sell one thats zero approved, as its been not available for awhile.

funny how in some threads how people turn into gatekeeping triple boarded OSHA, DOT, NHTSA Administrators, meanwhile we’ve all happily agreed to pre-alpha, alpha, beta, release candidate test a several thousand pound robot with no door handles that we have to add a rear view camera to.

as they say in the hospital, im “MD Aware” of the apocalyptic thermonuclear potential of using this specific product that I cant yet even buy. the OP asked the company about their progress in creating a 100 safe, tesla approved alternative to fix an annoying design decision that tesla made.

Not a single person here has such a truck. We all purchased rigorously tested vehicles.

No, they didn't specify "Tesla approved", just "validated". Anyone can validate their own product.

I posted this response because there are naive people out there who are blissfully unaware and unbothered on how much life ending electricity is flowing through those cables.

Put it this way pal, if I see anyone using one out in the wild I'm immediately reporting it to Tesla Roadside, where they can dispatch someone to the station. Tesla will eventually search the logs and find out who used it; possibly banning them from ever using the network again.

Tesla is also starting to install a lot more cameras at their stations. You should read their Terms of Use.

I use an EV-ject every time I charge
Any decently made CCS to NACS adapter won't have any issue at 500 amps and neither will EVJect.
"Disclaimer: NACS EVject may get hot during supercharging sessions from 0-35% when the charger exceeds its own amp rating. Please handle with care until EVject and charger wand cool down. EVject has been tested up to • 252 kW on Superchargers• 330 kW on CCS1 chargers. We don't recommend charging at rates above that at this time."

Seems like there's a risk at V4 cabinets...
