About Hk Ying Hui Yuan Group Ltd. - Electric Power Supply Components Supplier in China

Based in China, Hk Ying Hui Yuan Group Ltd. currently lists five active products in its catalogue. The supplier is classified under the top categories "Electric Power Supply Components" and "SMPS", indicating a focus on power conversion equipment. All five entries are European‑type power adapters rated at 12 V DC with different current capacities. Each product description explicitly mentions compliance with CE marking and RoHS directives, reflecting adherence to European safety and environmental standards. The catalogue does not provide additional technical data such as connector type or packaging dimensions, limiting the public product profile to voltage, current, and regulatory marks.

The five adapters are differentiated by output current: 5 A, 6 A, 6.5 A, 7 A and 7.5 A. They are all described as "Europe power adapter 12v" which typically implies a Europlug (Type C or Type E/F) compatible with European sockets. No HS codes are listed, so the supplier’s export classification is not disclosed in the source data. The product set targets buyers who need low‑voltage DC supplies for equipment operating at 12 V, such as networking gear, industrial control panels, or consumer electronics.

Product Range and Specialties of Hk Ying Hui Yuan Group Ltd.

The catalogue comprises five 12 V DC adapters with current ratings ranging from 5 A to 7.5 A. In the broader market, such adapters are commonly built to IEC 60950‑1 (now superseded by IEC 62368‑1) safety standards and are tested for voltage tolerance of ±5 % and efficiency above 80 %. CE marking confirms conformity with EU directives, while RoHS compliance restricts lead, mercury, cadmium and certain flame retardants to 0.1 % or lower by weight. Typical European adapters also specify a maximum operating temperature of 70 °C and include built‑in protection features such as short‑circuit and overload protection. Buyers often request datasheets that list input voltage range (e.g., 100‑240 VAC), output ripple (<150 mV p‑p), and connector dimensions.

Trade and Export Information - Hk Ying Hui Yuan Group Ltd.

China is a major exporter of low‑voltage power adapters, and shipments are usually classified under HS Chapter 85 (electrical machinery). European and North American distributors are the primary import markets for CE‑marked adapters, while Southeast Asian OEMs also source similar items for local assembly. Commonly required certifications include CE Declaration of Conformity, RoHS test reports, and, for some buyers, IEC type‑testing certificates. Export logistics typically involve 20‑ft or 40‑ft containers packed in cardboard boxes with anti‑static liners; FOB Shanghai or CIF Hamburg are frequent Incoterms. Chinese exporters often work with third‑party inspection agencies to verify CE and RoHS compliance before loading.

Sourcing from Hk Ying Hui Yuan Group Ltd. - Buyer Guidance

When sourcing from Hk Ying Hui Yuan Group Ltd., request a full CE Declaration of Conformity and the latest RoHS test report for each adapter model. Ask for a detailed datasheet that includes input voltage range, output voltage tolerance, ripple voltage, efficiency, connector type and protection features. Verify that the supplied current rating matches the intended application load and that the packaging complies with anti‑static handling requirements. Samples are useful to confirm physical dimensions, plug type and label wording before placing a bulk order.

What voltage and current ratings are offered by the adapters?

The supplier lists five models all delivering 12 V DC with current ratings of 5 A, 6 A, 6.5 A, 7 A and 7.5 A respectively.

Are the adapters CE marked and RoHS compliant?

Each product description includes "CE" and "RoHS", indicating that the supplier claims conformity with EU safety directives and the RoHS restriction limits.

What documentation should a buyer request?

Buyers should ask for the CE Declaration of Conformity, the most recent RoHS test report, and a technical datasheet covering input range, output tolerance, efficiency and protection features.

Is there a standard plug type for these European adapters?

European adapters of this class usually use the Europlug (Type C) or the grounded Type E/F; the exact plug type should be confirmed from the supplier’s datasheet.

What are typical packaging and shipping methods?

Adapters are commonly packed in anti‑static cardboard boxes, grouped in pallets for container loading. Export shipments often use 20‑ft or 40‑ft containers under FOB or CIF terms.

What minimum order quantity is typical for such adapters?

While the supplier does not state an MOQ, exporters of low‑voltage adapters often set MOQs between 500 and 1,000 units per model, depending on packaging and testing costs.

What lead time can a buyer expect?

Lead times for standard, CE‑marked adapters from Chinese manufacturers usually range from 30 to 45 days after order confirmation and receipt of required certifications.
