What Is a 20A USB-A/C GFCI Receptacle?
A 20 AMP GFCI Outlet with USB-C A/C receptacle is an indoor wall device that combines Class A ground-fault protection with built-in charging through one USB-A port and one USB-C port in a NEMA 5-20R receptacle format. This ShengYu model is listed as a 125V, 20A, tamper-resistant, self-test GFCI with 5.0A total USB output, 5V DC 2.4A on USB-A, and 5V DC 2.4A on USB-C. That makes it suitable for projects that need both higher-capacity AC receptacle formatting and broader device compatibility than a dual-USB-A-only design.
Who Should Use This Model
- Contractors sourcing indoor 20A GFCI + USB combo upgrades
- Commercial kitchen and breakroom project buyers
- Hospitality and lounge renovation buyers needing both legacy and newer charging formats
- Distributors building out indoor 20A combo receptacle inventory
When to Choose a Different Model
- Choose a 15A hybrid USB GFCI receptacle when the project calls for a standard NEMA 5-15R device instead of a 20A T-slot format.
- Choose a standard 20A TR GFCI receptacle when USB charging is not needed.
- Choose a WR GFCI receptacle when the installation requires weather-resistant construction, because this model is explicitly Weather Resistant: None on the live specification block.

Frequently Asked Questions (FAQ)
What is a 20A NEMA 5-20R GFCI receptacle with USB-A and USB-C ports?
A 20A NEMA 5-20R GFCI receptacle with USB-A and USB-C ports is an indoor wall device that combines Class A ground-fault protection with two different USB charging interfaces in one 20A receptacle format. It is used when a project needs both higher-capacity AC receptacle formatting and support for newer USB-C devices as well as legacy USB-A devices.
Can I install this 20A USB-A/C GFCI on a standard 15A branch circuit?
No. This is a 20A NEMA 5-20R receptacle, so it should not be used as a standard 15A replacement. For buyer-facing selection, the safe rule is to use a 20A receptacle on a 20A branch circuit and confirm the final installation against the circuit design and adopted code.
Will the USB-C port fast-charge a laptop?
No. The live specification lists the USB-C port at 5V DC 2.4A, which is standard 5V charging rather than high-voltage USB-C Power Delivery for laptops. This model is better suited to phones, tablets, scanners, and other standard USB devices than to notebook charging.
What does 5A total USB output mean?
A 5A total USB output means the built-in USB-A and USB-C ports share up to 5 amps of total 5V DC charging capacity. On this model, the USB-A port is listed at 5V DC 2.4A and the USB-C port is listed at 5V DC 2.4A, which makes the receptacle suitable for convenient dual-device charging in the same wall location.
Does this combination device need more wall-box space than a standard receptacle?
Yes. Combination devices that integrate 20A GFCI components and hybrid USB charging hardware can require more box space than a standard receptacle. That is why box volume and wiring space should be checked before replacement work begins, especially on remodel projects or boxes with limited depth.
Do the AC outlets on this unit accept both 15A and 20A plugs?
Yes. A NEMA 5-20R receptacle is designed around the 20A T-slot face pattern, and that format accepts standard 15A straight-blade plug use as well as 20A plug configurations. That is one of the main reasons buyers select a 20A combo device instead of a standard 15A USB charging receptacle.
Are the AC outlets tamper-resistant?
Yes. The AC receptacle portion of this model is tamper-resistant. The tamper-resistant shutter feature applies to the AC slots, while the USB-A and USB-C charging ports are separate charging interfaces.
Is this hybrid USB GFCI weather-resistant?
No. The live specification lists Weather Resistant as none, so this is an indoor USB GFCI receptacle rather than an outdoor WR device. It is suited to commercial kitchens, breakrooms, hospitality interiors, and similar indoor projects rather than exterior installations.

5-Step Quick Wiring Guide for GFCI Receptacles
This is a general wiring reference for standard U.S. GFCI receptacle installation. Always turn off power first and verify local code and product-specific instructions before installation.
- Turn Off Power: Switch off the breaker and verify the electrical box is de-energized with a voltage tester.
- Identify LINE and LOAD: Locate the incoming power cable for the LINE terminals. If a second cable feeds downstream receptacles, identify it as LOAD and use it only when downstream GFCI protection is required.
- Connect the LINE Wires: Connect the incoming hot wire to the brass LINE terminal, the incoming neutral wire to the silver LINE terminal, and the ground wire to the green grounding terminal.
- Connect LOAD Only If Needed: If downstream protection is required, connect the outgoing hot wire to the brass LOAD terminal and the outgoing neutral wire to the silver LOAD terminal. Do not reverse LINE and LOAD.
- Mount and Test the GFCI: Fold the wires neatly into the box, mount the receptacle and wall plate, restore power, press RESET, then press TEST to confirm proper operation before resetting again.
