Charging Speeds
with Magic Docks

As EV owners and advocates are well aware, 2024 will prove to be the year when automakers begin to adopt the J3400 charging standard (NACS), first with adapters and finally with dedicated plugs and ports so that any and all makes and models with CCS1 connectors will be able to plug in at Superchargers.

After only 6 days into the year, the sole accommodation for this change so far are Tesla Supercharger sites that boast “magic dock” adapters, as shown in the MotorTrend photo above. I think it safe to assume that, in the not-too-distance future, other automakers will begin to supply customers with similar adapters, such as Lectron’s Vortex Plug and A2Z’s Typhoon Plug. Apparently the latter company is even developing an extension cord because Supercharger cables are too short to reach the charging ports on other EVs without occupying more than one parking spot. Of course, Tesla will then eventually need to authorize Supercharger sites without “magic docks” to allow the use of such adapters.

As of this date, “magic docks” in the USA and Canada are few and far between. I can locate only 44 of them on this map by applying a filter for “Teslas + Other EVs,” —with one of them in Alaska, surprisingly enough, as shown below:

Out of curiosity to see how many other EVs have used these magic docks, I searched for them on PlugShare to find more specifics. Upon perusing the records that drivers had submitted, I was intrigued to see the charging speeds that their EVs attained. They seemed to vary greatly depending upon the make and model, and perhaps also because of the state-of-charge when they plugged in. I decided to make a list of the maximum speeds recorded at the 8 “magic dock” Superchargers near my location —still too far away for me to use, unfortunately. Here is a table that I compiled from those data:

If readers own one of the EVs in the table, perhaps it will help them anticipate what they can expect if and when they plug in at a “magic dock.” Truth be told, none of these other EVs achieved “blistering” charging speeds from a 250kW Supercharger, but several of them strike me as reasonably “fast.” Whether or not such speeds will prove consistent as other adapters become available, and as Tesla opens up more Supercharger sites… only time will tell.
