Shenzhen SOY Technology Co., Ltd

Shenzhen SOY Technology Co., Ltd operates in China and lists nine distinct power‑supply items in its catalogue. The listed items fall under the top categories Adaptors, Electric Power Supply Components, Mobile Phone Batteries & Chargers and Batteries & Chargers, reflecting a focus on electronic power conversion equipment. Each product is described with its output voltage and current rating, for example a 24 V 5 A desktop switching adapter and a 24 V 10 A 240 W switching adapter. The majority of the entries carry HS code 8504.40, the international classification for static converters and power supplies for voltage conversion. Materials are repeatedly noted as ABS housing combined with copper windings, PCB assemblies or FR‑4 substrates, indicating standard consumer‑grade construction.

The catalogue includes desktop and wall‑mount adapters ranging from 12 V 1.5 A up to 24 V 10 A, as well as laptop charger adapters rated at 20 V 3.5 A and 19 V 3.42 A. Typical industry specifications for such adapters include compliance with IEC 60950‑1 or the newer IEC 62368‑1 safety standards, output voltage tolerance of ±5 %, and efficiency levels above 80 % for switching designs. Common material grades are ABS or PC for the external housing, copper wire or copper windings for the power coil, and FR‑4 PCB for the electronic circuitry. Buyers often request CE, UL, GS or PSE markings, all of which appear in the product titles for several items, and may also look for RoHS compliance and electromagnetic compatibility (EMC) test reports.
