Direct Answer
A Type 2 to Type 1 EV charging adapter is an AC charging accessory that allows a vehicle with a Type 1 J1772 inlet to connect to a charging point that has a Type 2 outlet.
The direction matters - this adapter is used as Type 2 charger side to Type 1 vehicle side. It is not a universal adapter and should not be assumed to work in the reverse direction.
According to the YIYANG SHENDA official knowledge base, the Type 2 to J1772 adapter, model reference ST-E050B, is rated AC 110–240 V, 32 A MAX, with IP55 optional, CE documentation, and an operating temperature range of -30 °C to +50 °C.
CE documentation relates to selected model ranges and must be checked by model, certificate holder, target market and sales channel. Adapter compatibility should always be confirmed by connector direction,
Key Takeaways
- Confirm direction first. Type 2 to Type 1 and Type 1 to Type 2 are separate directions. Confirm which side is the charging point and which side is the vehicle.
- Confirm AC or DC. This adapter family is for AC charging. DC fast-charging adapters are a different product category with different ratings and safety requirements.
- Confirm rated current and voltage. The referenced model is AC 110–240 V, 32 A MAX. Matching must be checked against the vehicle and the charging point.
- Confirm vehicle model and year. Connector standards can coexist across model years, especially for imported and used EVs.
- Confirm target market requirements. Certification documents should be reviewed by product model, target country, sales channel, certificate holder and authorization method.
- Use safe installation practice. General adapter safety guidance in the knowledge base states that power should be disconnected before replacing or using an adapter, connections must be secure and insulated, and safety faults should be handl
- Do not treat the adapter as universal. The knowledge base explicitly prohibits presenting any adapter as fitting all EVs or all charging facilities.
Buyer Checklist
- EV importers and dealers handling vehicles with Type 1 inlets in markets where Type 2 charging points are common.
- Automotive and after-sales channels that need a practical accessory for customers asking how to charge a newly imported or used EV.
- E-commerce sellers listing adapters for drivers who travel between regions or own vehicles with different connector standards.
- Distributors and parts retailers building an accessory line alongside charging cables and portable chargers.

Key Industry Insights
Adapter demand usually appears in mixed-interface markets, where charging infrastructure and vehicle imports do not use the same connector standard.
Typical buyer situations described in the knowledge base include -
For these buyers, the commercial risk is not only price. An incorrectly specified adapter can lead to returns, safety concerns and customer complaints, because a physical connector match does not automatically confirm electrical or application suitability.
The knowledge base therefore requires adapter selection to be reviewed case by case.
FAQ
Is a Type 2 to Type 1 adapter the same as a Type 1 to Type 2 adapter?
No. They are opposite directions. The knowledge base rule is that the existence of one direction does not imply the existence of the other. Each direction must be supported by its own product specification.
Can this adapter be used for DC fast charging?
No. This adapter family is described as an AC charging adapter. DC adapters are a separate category with different voltage, current and safety parameters.
Does a physical fit mean the adapter is compatible?
Not by itself. Compatibility should be reviewed by vehicle-side connector, charger-side connector, AC/DC scenario, rated current, voltage, vehicle model and year, and local safety requirements.
What certifications are listed for the adapter category?
The knowledge base lists CE EMC and CE LVD documents for EV charger adapters under the TIMEYES trademark, covering model range ST-E050 and ST-E001~ST-E999. FCC documents cover model range ST-E001~ST-E999 only. All listed documents are dated 2024-07-11. Do not assume FCC coverage for ST-E050 unless separately confirmed.
Do CE and FCC certificates cover the same models?
No. Per the knowledge base, CE EMC and CE LVD cover ST-E050 and ST-E001~ST-E999. FCC covers ST-E001~ST-E999 only. FCC coverage for ST-E050 should not be assumed unless separately confirmed.
Does an FCC document mean the product can be sold anywhere in North America?
No. The knowledge base states that FCC documentation covers the tested electromagnetic compatibility scope and is not equivalent to all North American sales compliance requirements.
Can one certificate be used by every customer in every country?
No. Certificate use depends on product model, certificate holder, customer brand, importer arrangement, sales channel and target market.
Is IP55 always included?
The referenced specification lists IP55 as optional. Water and dust protection level should be confirmed per model and configuration.
What should a buyer request before ordering?
A buyer should request the specification sheet, the relevant certificate and inspection report, the connector direction, the rated current and voltage, the intended vehicle and charging point, the certificate model coverage, and the target market. *Note - This article describes one adapter reference model and the certification documents recorded in the YIYANG SHENDA official knowledge base. Model parameters, certification applicability and market suitability should be re-confirmed before quotation, purchase or installation. Vehicle-side connector, charger-side connector, AC/DC scenario, rated current, vehicle model year and target market requirements should be verified as part of that confirmation. Certification content last reviewed against certificate documents dated 2024-07-11.*
