Product Overview
The Fosmon 3 Outlet Wall Adapter Cube Tap is a smart, space-saving solution for anyone who needs more power outlets but lacks available wall sockets. Designed with both functionality and safety in mind, this compact adapter transforms a single standard outlet into three usable 125VAC sockets—perfect for charging phones, laptops, lamps, routers, and other low-to-medium wattage devices. Whether you’re at home, in the office, or traveling, this adapter offers a reliable way to expand your power access without cluttering your space with bulky power strips. Its sleek cube-shaped design ensures it sits flush against walls, making it ideal for tight spots behind furniture or appliances where traditional plugs would block adjacent outlets.
Engineered for durability and everyday use, the Fosmon Cube Tap features a sturdy plastic housing that resists wear from daily handling. The adapter operates as a passive splitter, meaning it doesn’t add electrical load but simply redistributes power from one outlet to three, keeping your circuits within safe limits. With its 90-degree angled plug, it minimizes strain on device cords and reduces tripping hazards near doorways or furniture. Plus, being ETL Listed by Intertek, it meets rigorous safety standards, giving you confidence in its performance and compliance with national electrical regulations.

This adapter is designed for indoor residential and commercial use only. It is not intended for outdoor, damp, or wet environments such as bathrooms or basements unless explicitly rated for such conditions. Since it does not include surge protection or voltage regulation, it should be used responsibly with devices that do not exceed typical household appliance wattage ratings. Always verify that the total power draw of connected devices stays within the circuit’s capacity to avoid overloading.

Benefits & Use Cases
The Fosmon Cube Tap excels in scenarios where wall outlets are limited or already occupied. It’s especially valuable in dorm rooms, bedrooms, home offices, hotel rooms, and rental units where installing new wiring isn’t an option. Travelers often find themselves in cramped accommodations with only one accessible outlet—this adapter solves that problem by maximizing existing socket availability.
The 90-degree plug design is particularly advantageous in tight spaces. For example, if you have a nightstand with two outlets and need to charge your phone, tablet, and lamp simultaneously, a flat plug might block the second socket. The angled design allows the Cube Tap to occupy only one outlet while still providing access to two others. Similarly, placing it behind a couch or TV stand helps manage cable clutter by eliminating the need for extension cords or power strips that extend outward.
Unlike surge-protected power strips, this adapter focuses solely on expanding outlet count without adding unnecessary components like USB ports or switches. This makes it lighter, simpler, and more cost-effective for basic power distribution needs. It’s also ideal for travelers who want to avoid carrying bulky adapters—just pack the Fosmon Cube Tap alongside your laptop charger and smartphone cable.
While it doesn’t support high-wattage appliances like microwaves, space heaters, or hair dryers, it’s perfectly suited for everyday electronics such as laptops (typically 60–90 watts), LED lamps (5–15 watts), Bluetooth speakers, Wi-Fi routers, and e-readers. Just ensure your home’s electrical system can safely handle the combined load of all plugged-in devices.


Important Notes
This product is intended strictly for indoor use and should never be used outdoors, near water sources, or in damp environments. Do not stack multiple adapters on top of each other, as this can create fire hazards and reduce airflow around the unit. Always inspect the adapter before each use for signs of damage, cracking, or loose parts. If any issues are detected, discontinue use immediately.
Remember that the Fosmon Cube Tap is a passive device—it doesn’t provide surge protection, power conditioning, or overload shutoff. While ETL Listing ensures it passes safety tests, responsible usage is essential. Avoid connecting devices that collectively exceed the amperage rating of your wall outlet (typically 15A for standard North American homes). For reference, most personal electronics consume well below 120 watts at 120V, so even three devices together rarely approach circuit limits.
No additional cables, manuals, or accessories are included beyond the adapter itself. The package contains only the Cube Tap unit. Users should already possess appropriate power cords compatible with their devices. This keeps the product simple, lightweight, and focused on delivering core functionality without bloat.
