Direct Answer
A NACS to J1772 AC adapter is a passive AC adapter that links a NACS charging connector on the charging-station side to a J1772 / Type 1 vehicle inlet on the vehicle side, so a J1772-equipped EV can charge at Level 1 or Level 2 AC from a NACS charging point.
The single most important selection criterion is direction - NACS must be the charger side and J1772 the vehicle side. The reverse direction is a different product, not the same adapter used backwards.
Equally important - this is an AC-only product. It is not a DC fast-charging adapter, and it should never be presented as one.
YIYANG SHENDA product documentation lists the NACS to J1772 adapter as model ST-E008A, with an operating range of AC 110V–250V, 32A MAX, IP55 / IP67 optional, and FCC and CE documentation.
Key Takeaways
- Wrong direction means the adapter will not fit at all. This is a mechanical and functional failure, not a minor inconvenience, and it usually surfaces after the goods have shipped.
- Using an AC adapter where DC charging is expected can be a genuine safety issue. Adapters should only be used in the scenario they were designed and tested for.
- Rated current drives the real charging rate. A 32A adapter on a 32A-capable circuit and vehicle delivers a different result than a lower-rated connection. Buyers should check the vehicle's onboard charger limit as well as the adapter rating
- Outdoor and semi-outdoor installations need the right ingress protection. IP rating affects whether the adapter is appropriate for a garage, a driveway, or a covered commercial car park.
- Market compliance is rarely a single document. YIYANG SHENDA data notes that certification should be reviewed by product model, target country, sales channel and certificate holder. FCC documents relate to the tested EMC scope and are not,

FAQ
What exactly does a NACS to J1772 adapter do?
It lets a vehicle with a J1772 inlet charge from a NACS AC charging connector. The NACS end connects to the charging equipment; the J1772 end connects to the vehicle.
Can I use it for DC fast charging?
No. The NACS to J1772 adapter is an AC adapter. DC fast charging requires a different, high-power DC adapter family, and the two should not be substituted.
Will it work on every electric vehicle?
No. Compatibility should be confirmed against the vehicle-side connector, the charger-side connector, the AC or DC scenario, the rated current and the vehicle model and year.
What current and voltage does it support?
YIYANG SHENDA data lists the NACS to J1772 model ST-E008A at AC 110V–250V with 32A MAX.
Is the adapter weatherproof?
IP55 / IP67 is available as an option. The correct choice depends on where the adapter will be stored and used.
Does it have certification?
YIYANG SHENDA data records CE EMC, CE LVD and FCC documentation for the adapter range. Final applicability should be checked by model and target market, and FCC documents should not be read as a complete market-access statement.
Can I use the same adapter in both directions?
No. Direction is fixed. A NACS to J1772 adapter is not a J1772 to NACS adapter.
Does the adapter change charging speed by itself?
No. Charging rate depends on the vehicle's onboard charger, the supply capacity and the adapter's rating together.
