China, the world’s main manufacturing hub for power plugs and adapters, offers a range of traditional and smart types. These devices come in two- and three-prong variants with round pins or flat blades to suit socket styles in different countries.
In the traditional category, widely available are power plugs based on assigned letters of the alphabet. There are A, B, C, D, E, F, G, H, I, J, K, L, M, N and O types, with 100 to 220V rated voltage, 50/60Hz frequency and 2.5,5, 10, 13 and 16A rated current. They are compliant with UL, cUL, VDE, CCC, CSA, BS, VDE, SAA, BSI, PSB, PSE, T-Mark and RoHS standards.
Common power adapters that can be sourced are wall-mount and desktop kinds with 100 to 240VAC input voltage, 50/60Hz frequency and 5, 9, 12 and 24VDC output voltage. These meet UL, CE, VDE, CCC, CSA and RoHS requirements.
In recent years, Chinese manufacturers have added smart plugs and adapters to their catalogs, riding on the automation trend. These products offer a convenient alternative to enabling remote control of appliances, A/V equipment, lamps and other devices from a mobile app.
Most suppliers use components, such as metal pins, wires, transformers and other passive components, controllers, PCBs and shells, sourced domestically. The cost of these materials has remained generally stable. However, due to competition, some companies lower their product prices to get more orders. This trend is expected to continue in the coming months.
