USB wall sockets combine a mains socket with one or more USB charging ports in a single wall device. For distributors and project buyers, the useful comparison is not just the number of ports: the selected model must fit the destination market, intended use and installation plan.
Specify the port arrangement
Record whether the project needs USB-A, USB-C or a combination, and how many ports should be available beside the mains socket. Port names alone do not describe charging performance. Ask for the output rating, supported charging protocols, and whether the stated output is shared or available per port when ports operate together.
Match the mains socket to the destination
Confirm the exact socket configuration, rated values and intended country before comparing USB features. A product title such as “USB socket” does not establish compatibility or approval for every market. Keep the socket configuration, USB charging specifications and relevant conformity documents tied to the quoted model code.
Check the installation format
Ask for a dimensioned drawing showing the faceplate, rear body, fixing points and required wall-box depth. Confirm whether the device is offered with a switch, indicator or cover, and whether those details vary by model. For a coordinated project, check that the appearance matches the selected switches and outlets.
Questions for the supplier
- Which USB port combinations are available for the target market?
- What output and charging protocols apply to each model?
- How is total output affected when multiple ports operate together?
- Which drawings and conformity documents cover the exact model?
- Are the selected colour, packaging and labelling available?
OUBEN’s catalogue includes socket models listed with USB combinations. Confirm the current specification and documents for the requested item code before approving a sample or order. Treat every open field as a question to resolve; another model’s rating should not be assumed to apply.
