Import Adaptor — Buy in wholesale FOB from Supplier in China

Hangzhou Guanbo Technology Co., Ltd supplies a regulated AC-DC power adaptor with universal input capability of 115 VAC or 220 VAC, delivering a stable 12 VDC output at 1 ampere include over-voltage and short-circuit protection, which are essential for unattended or continuous-operation equipment where supply anomalies could cause damage or fire risk. The construction uses ABS housing with copper windings, a common combination for cost-sensitive power supplies where thermal management and electromagnetic compatibility must be balanced against unit cost.

The regulated output distinguishes this adaptor from unregulated alternatives, maintaining 12 VDC within a tight tolerance band despite input voltage swings or load variations. This stability is critical for sensitive electronics such as routers and CCTV cameras, where voltage ripple or sag can cause data corruption, recording failures, or premature component failure. Copper windings in the transformer or inductor sections provide the magnetising current path with lower resistive losses than aluminium alternatives, though core material and winding geometry ultimately determine efficiency and temperature rise. ABS housing offers mouldability for complex shapes and adequate electrical isolation, but thermal conductivity is low, so internal heat must be dissipated through convection and radiation rather than conduction to the enclosure.

Importers and distributors in the consumer electronics and security equipment supply chains represent the primary buyer segments for this adaptor. It is suited to applications where a single 12 V rail at modest current is required, such as small network appliances, LED strip controllers, and analogue CCTV camera installations. OEMs integrating the adaptor into finished products should verify the output ripple specification, conducted and radiated emission classes, and mean time between failures data. Bulk procurement buyers should confirm whether Hangzhou Guanbo Technology offers customised cable lengths, connector types, or branding options for volume orders.

Hangzhou Guanbo Technology Co., Ltd is located at No. 30 Wantang Road, High-New East Technology Zone, Hangzhou, Zhejiang Province 310012, China. The company sits within the Hangzhou high-technology corridor, an area with substantial concentration of electronics manufacturing and power supply design firms. The trust tier is listed as harbor, with a response rate of 0.00 percent and zero recorded average response hours, indicating no verified engagement metrics are available. The supplier profile does not state year of establishment, workforce size, annual revenue, or factory floor area, so these details must be obtained through direct inquiry.

The source description identifies the company as active in regulated AC-DC power supply products, with this specific listing targeting the 12 V/1 A segment for routers, CCTV cameras, and LED applications. No client names, export destinations, or additional product families are mentioned. The address places the firm in a technology zone with access to Shanghai Ningbo port logistics and Hangzhou Xiaoshan International Airport for air freight. Buyers should treat the initial engagement as a full qualification exercise, requesting company registration documents, quality system certifications, and reference customers before committing to volume orders.
