Leviton GUSB1-W 15A SmartlockPro GFCI USB Charger Outlet - Fast Safe

In this review of the Leviton GUSB1-W SmartlockPro GFCI combination outlet, the bottom line is simple: this is a safety-first wall outlet with powerful built-in USB charging that suits kitchens, bathrooms, and other areas where code requires ground-fault protection. The reviewer found it most compelling for homeowners who need GFCI protection plus the convenience of dual high-current USB ports, delivering quick charging for phones and tablets without adding a separate adapter.

Key Features

• Dual high-powered USB ports: Two Type A ports supply a combined 3.6A to charge smartphones and tablets faster than typical USB GFCI outlets.
• Self-test GFCI protection: The device automatically conducts internal tests to confirm ground-fault protection is available and indicates problems with visual or audible alerts.
• Code-compliant design: Meets NEC requirements for locations that require GFCI protection, making it suitable for bathrooms, kitchens, garages, and outdoors where specified.
• Tamper-resistant outlets: Built-in shutters protect against foreign object insertion, improving safety in family homes or public spaces.
• Status indicator light: A simple visual indicator provides intuitive feedback on device readiness and fault conditions.

Who It's For

The Leviton GUSB1-W is ideal for homeowners, electricians, and renovators who need a single device that combines reliable GFCI protection with high-speed USB charging in code-sensitive areas such as bathrooms and kitchens. It works well for households that prefer built-in charging without wall-wart adapters crowding outlets.

It is less appropriate for installers who only need a basic GFCI outlet without USB ports, or for setups with shallow electrical boxes, since the unit requires an extra-deep wallbox and a separate wallplate. Customers seeking USB-C ports should look elsewhere, as this model provides Type A ports only.

Pros & Cons

Pros

• Combined GFCI and USB charging saves space and provides code-required protection in one device.
• High combined USB output (3.6A) charges phones and tablets faster than many GFCI USB outlets.
• Self-testing GFCI adds ongoing safety with automatic monitoring and clear indicator feedback.
• Tamper-resistant design and robust build quality match what customers report about durability and ease of installation.

Cons

• Requires an extra-deep wallbox and wallplate sold separately, which can complicate retrofit installations.
• No USB-C port option, so users with newer devices may still need an adapter or cable.
