20-amp version of the Efficere Basic USB outlet for circuits wired with 12 AWG and a 20-amp breaker, kitchen counters, home offices on dedicated 20A circuits, laundry areas. The 5-20R configuration accepts both 15A and 20A plugs. Same dual Type A 21W USB as the 15A model; the 20A rating is for the AC receptacle circuit capacity, not the USB output. Tamper-resistant, screwless wall plate included.
When do I need a 20-amp USB outlet vs a 15-amp?
Use a 20-amp USB outlet only on a 20-amp branch circuit wired with 12 AWG conductors and protected by a 20-amp breaker. It is appropriate where the circuit must serve equipment with 20-amp plugs or where code and circuit design call for a 5-20R receptacle configuration.
The USB output is 21W, is that enough for all my devices?
It is adequate for phones, tablets, and many small electronics, but it is not ideal for modern USB-C fast charging or laptop charging. The USB section provides standard 5V charging at up to 4.2A total, shared across the two Type A ports.
Can I install this outlet on a 15-amp circuit?
No. A 20-amp receptacle with a 5-20R face should not be installed on a 15-amp branch circuit because it can accept a 20-amp plug that the circuit is not designed to support.
What does the 5-20R slot configuration mean?
A 5-20R receptacle has one T-shaped neutral slot so it can accept both standard 15-amp plugs and 20-amp plugs. That configuration identifies the device as suitable for 125V, 20-amp branch circuits.
