Overview
The DOACE 3-Inch Power Grommet is a flush-mount desk accessory that integrates two AC outlets and four USB charging ports into a single, tidy unit. With two USB-C PD 3.0 ports (20W each) and two USB-A ports (18W each), it can simultaneously charge smartphones, tablets, and other small devices while keeping your desktop clutter-free. Installation requires a 3-inch (76mm) hole in your desk surface. The included locking ring secures the grommet firmly, and the 6-foot flat plug extension cord provides flexibility in placement. ETL certified and built with fire-resistant materials, this power tap is designed for safe, long-term use in home offices, gaming setups, and conference rooms.
Connectivity & Compatibility
The AC outlets support 125V/12A/1500W total, suitable for monitors, lamps, and other desk peripherals. The USB-C ports support Power Delivery 3.0 up to 20W, ideal for fast charging iPhones, Android phones, and tablets. USB-A ports deliver 18W for older devices. Compatibility requires a desk top thickness of up to 30mm (1.18 inches) and a 3-inch diameter cutout. The flat plug is low-profile, fitting behind furniture easily.

Best Use Cases
Remote workers and home office users: Keep your desk tidy by consolidating power and charging for your laptop, phone, and tablet in one spot. The USB-C ports are great for quick top-ups during the workday. Gamers and streamers: Reduce cable clutter around your monitor and peripherals. Note that high-power gaming PCs should still use a dedicated power strip. * Shared desks and meeting rooms: Install in conference tables so participants can easily charge devices without hunting for outlets. USB-C fast charging is a plus for short meetings.
Things to Consider
Installation requires drilling a 3-inch hole, which may not be suitable for renters or those unwilling to modify their desk. The USB total output is limited to 40W, so charging a laptop via USB-C will be very slow—use the AC outlets for that. Also, the AC outlets are 2-prong only (no ground), so devices with grounded plugs may need an adapter. ## FAQ
Q: Can this grommet be installed on metal or plastic desks? A: Yes, as long as the material can be drilled and the thickness is within 30mm. Wood, metal, and thick plastic are all fine. Q: Will the USB-C ports charge my laptop? A: They output 20W, which is enough for phones and tablets but insufficient for most laptops (which typically require 45W or more). Use the AC outlets with your laptop's original charger. Q: Is there a warranty? A: The manufacturer does not specify a warranty period, but purchases are covered by their 30-day return policy.
