How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.
On current and voltage these two are close enough that the numbers do not decide anything. The certification does.
Side by side
| Lectron Vortex Plus | A2Z Typhoon Pro | |
|---|---|---|
| Voltage | 1,000 V | 1,000 V |
| Current | 500 A | 500 A on liquid-cooled cables; 400 A otherwise |
| Superchargers | V3 and V4 | V3 and V4 |
| Interlock | Yes | Yes |
| Heat protection | May reduce or pause charging | Two sensors: derate, then stop |
| Weather rating | IP67 | IP54 mated, IP67 enclosure |
| UL 2252 | Certified, tested by SGS (per Lectron) | In progress (per A2Z) |
| Warranty | 2 years | 12 months |
The differences that matter
- Certification. Lectron states UL 2252 certification; A2Z states its certificate is pending. Certification wording.
- Warranty. Two years against 12 months.
- Heat handling. A2Z publishes a two-stage sensor design; Lectron says its adapter may reduce or pause charging in very hot conditions.
- Authorization. A2Z's page says third-party adapters are not currently officially authorized on Tesla Superchargers; check your automaker's guidance for either.

Full published specifications and the case against each.
1. A certified third-party adapter
Lectron Vortex Plus NACS to CCS1 adapter
Lectron · NACS to CCS1 · 500 A
A NACS-to-CCS1 DC adapter with an interlock, certified to UL 2252 and tested by SGS, per Lectron. Rated 500 A and 1,000 V, IP67, for V3 and V4 Superchargers -- and only for cars whose automaker has approved Supercharger access.
What is good
- Certified to UL 2252, the standard written for EV adapters, per Lectron
- Interlock keeps the connection secure during DC charging
- IP67 dust and water rating
- Two-year warranty
What is not
- Only for cars whose automaker has approved Supercharger access
- V3 and V4 Superchargers only -- not V2, and not AC chargers
- Your automaker's own adapter, if it offers one, is the first choice
| Rating | 500 A / 1,000 V / 500 kW |
|---|---|
| Direction | NACS DC charger to a CCS1 port |
| Chargers | V3 and V4 Tesla Superchargers; not V2, not AC chargers |
| Vehicles | CCS1 EVs with approved automaker Supercharger access |
| Interlock | Built in |
| Heat | May reduce or pause charging in very hot conditions |
| Weather rating | IP67 |
| Certification | UL 2252, tested by SGS, per Lectron |
| Warranty | 2 years |
Skip this if: Skip it if your automaker supplies or sells its own NACS adapter for your car -- that part comes first -- or if your car already has a NACS port.

The verdict
Lectron Vortex Plus: the published UL 2252 certification and the longer warranty decide it. Revisit the A2Z Typhoon Pro once A2Z publishes its certificate. Either way, check whether your automaker offers its own adapter first. The full roundup.
