Import 5v0.5a Ac/Dc Adapter — Buy in Bulk from Supplier in China

This 5V0.5A AC/DC adapter from Greatking Hongkong Technology Co., Ltd. is a low-power wall-mount switching supply delivering regulated 5V DC at 0.5A for 2.5W continuous output. The unit ships with interchangeable plug heads covering UL (North America), EU, UK, and AU configurations, enabling multi-region deployment from a single SKU. The standard DC output connector is specified as 5.5mm × 2.1mm in an L-type barrel configuration, a near-universal size for small electronics.

Construction is described as durable for daily use, though specific enclosure material (typical ABS or PC blend for this class) and ingress protection rating are not stated. The white box and carton packaging option, with custom branding available, suggests OEM/ODM orientation typical of Shenzhen-area electronics manufacturers. The supplier notes CE compliance, though full certification scope and corresponding test standards are not detailed in the source material.

Primary applications include consumer electronics, small appliances, and portable devices requiring stable 5V input. The 2.5W output suits microcontroller boards, small sensors, LED indicator systems, and legacy USB charging applications. Buyers should confirm with the supplier whether the adapter includes active power factor correction or meets specific efficiency regulations (such as EU ErP or US DoE standards), as these requirements vary by application and destination market.

Greatking Hongkong Technology Co., Ltd. maintains its registered address at No.49 Dabao Road, 28th District, Baoan, Shenzhen, Guangdong, 518133, China. The company holds both imported supplier tier and harbor trust tier designations on the platform, with a recorded response rate of 0.00% and zero average response hours. This absence of verified communication history means buyers should initiate direct contact early in the sourcing process to assess responsiveness and verify active operations.

The Shenzhen Baoan location places the supplier within one of China's densest electronics manufacturing corridors, with extensive component sourcing and contract manufacturing infrastructure. The emphasis on customizable packaging and multi-standard plug heads indicates a business model oriented toward OEM branding and regional distribution. The Hong Kong company name with mainland Shenzhen operations is a common structure for export-focused electronics firms. Buyers should verify whether the supplier owns manufacturing facilities or operates as a trading company, as this affects quality control traceability and direct technical support capabilities.
