You can install a USB-C outlet behind the trim of an interior door in a Florida home. This provides a convenient charging option for devices like phones, tablets, and laptops, keeping floors clear of chargers and cables. Given Florida's humidity and the possibility of power-washing garage floors, protecting the outlet from moisture is essential.
The Leviton T5635 is a commonly chosen outlet for this purpose. It can deliver a total of 30 W of power—15 W per port when both ports are in use—while still having two standard AC receptacles. The outlet is UL-listed and IP20-rated, confirming its safety and resistance to humidity. Note that it doesn't come with a wall plate, which will need to be purchased separately. The outlet's built-in charge-status LEDs are also helpful for knowing when a device is fully charged.
To install the outlet without damaging the door trim, you will need:
12-volt drill 1-inch pry bar Finishing nails Silicone gasket or UL-approved sealing tape 15-A circuit breaker GFCI outlet Standard 3-way outlet box
The drill will be used to remove the existing trim, while the pry bar helps to lift trim without breaking it. Finishing nails will reattach the trim after the outlet is installed. A silicone gasket will create a moisture barrier, and the GFCI outlet adds safety in a humid environment. The outlet box should be either metal or high-impact plastic rated IP20.
Turn off the power at the breaker. Carefully remove the trim, ensuring the jamb remains intact. Install the outlet box into the cavity, making sure it is level and flush with the jamb. Wire the outlet according to the instructions, connecting both AC receptacles and the USB-C ports. Mount the outlet and attach the silicone gasket around the mounting flange. Install the wall plate and reattach the trim using finishing nails. Test the outlet with a USB-Power Delivery analyzer or a device known to work.
The primary concern is moisture ingress, which can lead to corrosion of the USB-C pins. A silicone gasket or UL-approved sealing tape around the outlet’s mounting flange can help protect against humidity. If the outlet is placed near a window or door leading to a garage, consider using an IP44-rated outlet for better protection.
Be cautious when cutting the trim; a shallow cut helps maintain the jamb's integrity. Use a pry bar to lift the trim and keep the jamb free from gaps that could allow moisture in. After installation, apply a clear sealant to the edges of the trim to further block moisture. Installing a dedicated 15-A circuit with a GFCI breaker is advisable in areas with high humidity or frequent power washing.
Regular inspections are important. Check every year for moisture signs on the trim or outlet faceplate. If discoloration or a musty odor is present, replace the gasket or reseal the area. With proper sealing, a UL-listed outlet can last 12–20 years in a Florida home, providing reliable charging without the mess of separate chargers.
