The four adapters at a glance
| Adapter | Plug into | Fits car port | AC or DC | Works at home? |
|---|
| Lectron Vortex Plus (NACS to CCS1) | Tesla Supercharger cable | CCS1 | DC only | No |
| Lectron Vortex Plug (NACS to CCS1) | Tesla Supercharger cable | CCS1 | DC only | No |
| Lectron J1772 to NACS, 80 A | Any J1772 charger | NACS (Tesla) | AC | Yes |
| Lectron NACS to J1772, 48 A | Tesla Wall / Destination Charger | J1772 | AC | Yes |
The price gap between the AC and DC halves of this table is the thing to internalize. An AC adapter is a passive connector shell with pins in it. A DC adapter is a part rated for hundreds of amps at up to a thousand volts, with a locking mechanism and a certification question attached. They are not interchangeable at any price.
Vortex Plus or Vortex Plug? The difference is in the wording
Both carry identical headline figures — 500 amps, 1,000 volts, 500 kW — and the two products differ in three places, all of which are Lectron’s own wording on its own two product pages rather than anything we measured:
Certification language.The Plus is described as “UL2252 Certified” and “tested by SGS”. The Plug is described as “UL2252 Compliant”, and its own FAQ says it “adheres to UL 2252 design standards”. Compliant and certified are not the same claim, and on a part that carries 500 amps we treat that distinction as the main reason to pay the difference.
Retention.Lectron publishes an “automatic internal dual-locking mechanism (interlock) on both the NACS and CCS1 connections” for the Plus, and a “manual locking latch” for the Plug — explicitly contrasting the two itself.
What is published at all.The Plus publishes IP67 and a two-year warranty. The Plug’s page publishes no ingress-protection rating, no warranty term and no dimensions. That is three unknowns on a part that lives in a bag in a car.
Our full Vortex Plug versus Vortex Plus comparison has the nine-row table and the Supercharger-generation caveat. The short answer for most buyers: the Plus, because the price difference is small relative to what is at stake, and the Plug only if the saving matters more than three published specifications.
The question that sends most people to this page
Live search completions for “best NACS adapter” are dominated by specific non-Tesla EVs — the IONIQ 5, the Mach-E, Rivian, the Kia EV6, the F-150 Lightning, the Chevy Bolt, the Polestar 2, the Lyriq. Almost all of those drivers are asking about case 3 above: fast charging at a Supercharger. Two things to know before you buy for that:
Access is granted by your automaker, not by the adapter. Lectron’s own page states the Vortex Plug is designed exclusively for CCS1-equipped EVs with automaker-granted Supercharger access, and it names the brands its FAQ covers. If your car does not have access, the adapter changes nothing.
Many of these cars now ship with a NACS port already.If your car has a native NACS socket, you do not need a DC adapter for a Supercharger at all — you plug straight in. Our J1772 versus NACS explainer shows both port shapes so you can check your own car rather than relying on a model year. The thing those cars often do need is the opposite direction for AC: a NACS car plugging into a J1772 home charger.
Adapters and home charging
One rule covers everything on this page: a DC adapter never helps at home. If you drive a Tesla or any NACS car and the charger on your wall is J1772, the adapter you want is the inexpensive AC one — and after that, every charger on this site is available to you, which is the real reason to own one. See the full J1772-to-Tesla adapter review for the amperage and heat questions, and the best home chargers for a Tesla for the alternative: buying a native NACS charger and carrying no adapter at all.
If you are going the native route, our NACS home charger roundup and our Tesla Wall Connector alternatives cover the hardware. And if you inherited a Tesla charger with a house and drive something else, the NACS-to-J1772 adapter in fourth place above is the cheapest way to make that wall useful — reviewed in full here.
One honest note on that fourth pick. It dropped off our daily retailer check for a spell, with no price returned, which is why it sits fourth rather than higher; the listing is live again, so its button should show a number rather than a bare “Check price on Amazon”. On any day the check cannot verify a price you will see the bare button instead, because we will not print a figure we have not confirmed. Its lasting reason for being fourth is narrower: it is the only part on this page that does its direction, and that direction — a non-Tesla car drawing from a Tesla AC connector — is the rarest of the four situations above.
What we are not telling you
We own none of these adapters and have not plugged them into anything. Every figure above is read from Lectron’s own product pages on the dates recorded in our sources, and the certification comparison is a comparison of published claims, not of test results. We also publish no DC charging speed for any car-and-adapter combination, because that is set by the vehicle, the Supercharger generation and the battery temperature, and no one involved publishes a figure we could stand behind.
