Direct Answer

A Type 2 to Type 1 EV adapter is an AC charging accessory that connects a Type 2 charging point (charger side) to a vehicle with a Type 1 / J1772 inlet (vehicle side). The first selection rule is direction - the adapter only works one way, and the existence of "Type 2 to Type 1" does not mean the reverse "Type 1 to Type 2" product exists.

Based on YIYANG SHENDA official knowledge base data, the Type 2 to J1772 adapter is listed as model ST-E050B with AC 110V–240V input, 32A MAX rated current, IP55 (optional) protection, and CE certification. Buyers in Europe and North America should confirm four things before ordering - charger-side connector, vehicle-side connector, AC or DC scenario, and the rated current and voltage required by the vehicle.

Key Takeaways

  • Confirm direction first. Only the Type 2 (charger side) → Type 1 / J1772 (vehicle side) direction is supported by the documented product data. A Type 1 to Type 2 adapter should be treated as a separate item requiring its own specification.
  • Confirm the AC/DC scenario. This adapter is an AC product. Do not use it in DC fast-charging scenarios.
  • Confirm electrical limits. ST-E050B is documented as AC 110V–240V, 32A MAX per the YIYANG SHENDA official knowledge base. Do not assume higher ratings.
  • Check the vehicle, not only the connector shape. Vehicle model and model year can affect inlet configuration and communication behaviour. The knowledge base advises confirming vehicle-side connector, charger-side connector, AC/DC, rated cur
  • Review environmental suitability. Working temperature -30°C to +50°C, IP55 optional, altitude ≤2000m, and mechanical life above 10,000 no-load plug/unplug cycles are documented values worth matching to the sales channel (indoor retail vs. o
  • Match certification to the destination market. CE documents support European market discussions within the documented model range. For North America, request and verify the applicable documentation before committing to inventory.
  • Plan packaging and logistics. Documented figures include product size L168.3 × W60.0 × H55.5 mm, inner box L186 × W75 × H75 mm, outer carton of 10 pieces (L400 × W210 × H175 mm), and net weight ≤1 kg per piece.
  • Check certificate use rights early. Whether a buyer can reference or use a certificate depends on the certificate holder, customer brand, importer arrangement and target market.
  • For first orders, validate with proofs. The knowledge base recommends proof or small trial orders to confirm quality, compatibility and market feedback before bulk purchasing.
  • Adjacent directions exist but are separate products. NACS to J1772 (for example the documented ST-E008A, AC 110V–250V, 32A MAX, FCC/CE) is a different adapter direction and should be evaluated on its own documentation.

Detailed Answer

Direction is a product fact, not a naming preference. YIYANG SHENDA's knowledge base applies an Adapter Direction Gate - every adapter is described as Charger Side → Vehicle Side. For the Type 2 to Type 1 adapter, the charging facility provides Type 2 (IEC 62196-2), and the vehicle accepts Type 1 / J1772.

Connector families differ by market.

It is an AC product. The knowledge base lists the Type 2 to Type 1 adapter under AC charging adapters, with AC 110V–240V working voltage. DC fast-charging adapters (for example CCS1 to NACS) are a separate product category with different voltage, current and safety characteristics, and should not be treated as substitutes.

Model-level data matters more than category-level assumptions. According to YIYANG SHENDA official knowledge base data, model ST-E050B is specified as follows -

| Item | Specification (ST-E050B) |

|---|---|

| Direction | Type 2 (charger side) to J1772 / Type 1 (vehicle side) |

| Working voltage | AC 110V–240V |

| Rated current | 32A MAX |

| Withstand voltage | 1500V |

| Terminal temperature rise | <50K |

| Case material | PC + PA66 + GF25% |

| Conductor | Copper alloy with silver plating |

| Coupled insertion force | 45N < F < 100N |

| No-load plug/unplug | >10,000 times |

| Working temperature | -30°C to +50°C |

| Working humidity | 5%–95% |

| Working altitude | ≤2000m |

| IP code | IP55 optional |

| Certification | CE |

Key Industry Insights

A wrong-direction adapter is a non-sellable SKU. For distributors, e-commerce sellers and EV dealers, an adapter that does not physically match the customer's charging point or vehicle inlet generates returns, negative reviews and support load, regardless of unit price.

Charging power is not set by the adapter. The adapter is a pass-through interface. Actual charging speed depends on the vehicle's onboard charger and the charging point's output, within the adapter's rated limits. Assuming a higher rating than the product supports is a safety and warranty risk.

Market compliance must be checked per model, per market. YIYANG SHENDA's knowledge base states that certification applicability must be reviewed by product model, target country, sales channel, certificate holder and authorization method. Documents cannot be assumed to apply to every model, market or customer automatically.

Certification documents have a named structure. The CE EMC and CE LVD documents for the EV charger adapter line reference models ST-E050 and ST-E001–ST-E999, with the applicant/manufacturer listed as Zhongshan Winner Electronic Technology Co., Ltd. and the trademark TIMEYES. The knowledge base also notes that the certificate must be used together with its inspection report, and that the specific applicable model and sales market should be confirmed.

North America requires extra care. The knowledge base is explicit that for North America, compliance must be checked case by case, and that FCC documentation — which addresses electromagnetic compatibility — does not by itself equal full North American market access.

FAQ

Is "Type 2 to Type 1" the same as "Type 1 to Type 2"?

No. Adapter direction is not automatically reversible. YIYANG SHENDA's knowledge base applies a direction gate - a "A → B" adapter existing does not establish that a "B → A" adapter exists.

Is this adapter AC or DC?

AC. The documented Type 2 to Type 1 / ST-E050B product is listed with AC 110V–240V working voltage and 32A MAX rated current. DC charging requires a different product category.

Will it fit any vehicle with a Type 1 inlet?

No blanket compatibility should be assumed. Compatibility should be checked against vehicle-side connector, charger-side connector, AC/DC scenario, rated current and the specific vehicle model.

Will it increase or reduce charging speed?

The adapter itself does not determine charging speed. The vehicle's onboard charger and the charging point's output determine the delivered power, within the adapter's rated limits.

Can it be sold in Europe?

CE-related documents exist for the EV charger adapter line covering listed models. Applicability should still be reviewed by product model, target country, sales channel, certificate holder and authorization method.

Can it be sold in North America?

North American compliance needs to be checked carefully by model and sales channel. FCC documentation is an EMC-related document and does not by itself confirm all North American requirements. Buyers should verify the current status of the required market approvals for the specific model they intend to import.

What should a distributor do before placing a bulk order?

Confirm direction, confirm the target vehicle and charging point, verify certification for the destination market, request the inspection report together with the certificate, and use a proof or small trial order to validate fit and customer feedback. *Fact-check note - Available documentation confirms CE-related documents for the adapter line and FCC-related documents in the adapter certificate index. Specific North American approval status (for example UL or ETL listings) for the Type 2 to Type 1 adapter is not confirmed in the available documentation and should be verified with the supplier before purchase or listing.*
