FAQ

Can I replace an outlet with USB myself?

Yes, if you're comfortable with basic electrical work and have the proper tools. Always turn off the power at the circuit breaker before starting.

Why is my outlet with USB not charging my phone?

Possible causes include a faulty USB port, lack of power to the outlet, or a damaged charging cable. Test with a different device and cable to isolate the issue.

How do I know if the circuit breaker is the problem?

Check if the breaker is tripped or damaged. If it trips again after resetting, there may be an overload or short circuit in the circuit.

Can I use a regular outlet instead of a USB outlet?

Yes, but you'll need a USB adapter or power strip with USB ports to charge devices.

Are USB outlets safe to use?

Yes, when installed correctly and used within their rated capacity. Avoid overloading the circuit to prevent overheating.
