Outdoor GFCI Outlet Box with USB-C & USB-A Ports - Weatherproof Power

In this review of the Outdoor GFCI Outlet Box with USB-C and USB-A ports, the bottom line is simple: it is a sturdy, weatherproof outdoor power solution for yards, patios, and lighting circuits. The unit pairs a 120V, 20 AMP GFCI receptacle with dual USB ports (Type-A and Type-C) for a compact combination of safety and convenience. The standout reason to buy is the metal, 3R-rated enclosure that resists rain, dust, and rust while including everything needed for a basic outdoor installation.

Key Features

• 20 AMP GFCI Receptacle: Protects outdoor circuits by interrupting power during a ground fault, improving safety for wet-area outlets.
• Dual USB Ports: Provides Type-A and Type-C charging with a combined max output of 5V/4.5A, convenient for charging phones and small devices outdoors.
• All-Metal Weatherproof Box: The 3R-rated galvanized steel enclosure is built to resist rain, dust, and rust for longer outdoor life.
• Easy Installation: Multiple knockouts on the side, bottom, and back and ample wiring space simplify mounting and wiring tasks.
• Lockable Cover: The metal cover can be secured for added protection in public or shared outdoor areas, increasing physical security.
• Complete Kit: Includes the steel box, gasket, metal cover, and the 20 AMP GFCI, so installers receive the main components together.

Who It's For

The box is ideal for homeowners, landscapers, and contractors who need a reliable outdoor outlet for backyard lighting, small power tools, or device charging where moisture and dust resistance matter. It works well for patios, garages, campsites, and areas that require a lockable, tamper-resistant exterior outlet solution.

It may not be the best fit for high-demand commercial charging stations or appliances that exceed the combined USB output or require multiple high-amp circuits; those users should consider dedicated outdoor equipment rated for heavier loads or multiple circuits.
