Full Guide to USB Wall Outlet Installation

April 13, 2026

Installing USB outlets in the home is a simple upgrade that not only adds charging convenience but also modernizes the way we use power. Did you know that the average American home has about 70 receptacles, according to the Electrical Safety Foundation International, and approximately 17-21 connected devices – from smartphones to laptops to e-readers to headphones? As the number of devices used that require a charge increases, as does the need for more charging space in the home. Instead of stocking up on power strips, USB outlets provide additional charging ports where they are needed most.

Follow our guide to choosing and installing the right USB receptacle for your space based on needs, quality, performance and style.

Why Install a Built-in USB Outlet

Let’s start with why you might even consider upgrading to USB outlets.

Modernizing the home with built-in USB ports in place of standard outlets is a no-brainer. It removes the hassle of searching for a charging brick and the struggle of fighting for charging space. It adds a level of future-readiness that is beneficial for everyday life as well as potentially adding value and interest to homebuyers down the road.

• Reduces Clutter: USB outlets are ideal for high traffic areas of the home or where devices are commonly used. They eliminate the need for power adapters and power strips.
• Adds Extra Charging Space: Outlets with built-in USB ports can add two additional spaces for charging needs so everything can be plugged in at once without overloading the outlet.
• Delivers Faster Charging: USB outlets come in a variety of wattages to support the charging needs of modern devices (see more on this below). For example, a 65W USB outlet can sufficiently charge a laptop, tablet, smartphone and more.

Are Wall Outlets with USBs Safe?

Wall outlets with USBs are safe, but not every USB is created equal. One of the first things to look for is the brand reputation. With a flood of brands to the market, it’s important to choose an outlet from a brand with reliable engineering and verified test data. Plus, there are a number of features that are key for determining whether an outlet is going withstand heavy wear and maintain the highest level of safety.

USB Safety Features to Look For and Why they Matter

• UL Listing: A UL listing proves that the outlet meets electrical safety standards. Be cautious of misleading or vague claims and double check that the packaging/product has a proper UL marking.
• Power Delivery: Automatically delivers the optimal charging voltage and current dependent on the device that is plugged in.
• Intelligent Thermal Sensing: Prevents overheating to protect the outlet and device.
• GaN Technology: Enables higher efficiency charging in a smaller form factor while generating less heat.
• Tamper Resistance: Required by NEC for safety for all residential outlets.

How to Choose the Right USB Outlet Type

There are a variety of USB outlet types to choose from, which can be overwhelming. Consider the port type, installation location code requirements, wattage and number of ports when determining the best outlet for a space.

Consider Type A vs. Type C USB ports

• Type-A ports: These are larger and, by today’s standards, charge fairly slowly. However, there are devices that still charge with a type-A port. If you’re considering a type-A USB, we recommend a Type A/C USB with an option for both.
• Type-C ports: For a more future-ready option, type-C ports offer more flexibility for the long-haul. The new standard in charging is the type-C, and some states are even requiring that devices only use type-C to reduce the number of adapters and cords that become outdated.

Understand Wattage Compatibility for Common Devices

From headphones to laptops, devices require sufficient power to charge in an efficient way. When choosing the right wattage, know what types of devices you’re going to be powering. Here’s a short list of some of today’s most commonly used devices and their required wattage:

• 15W: wireless headphones, smartwatches
• 30W: smartphones
• 45W: tablets
• 65W: small laptops

Determine if you Need GFCI Protection

According to the National Electrical Code, GFCI protection is required for spaces like the kitchen, bathroom and laundry room. Check the code requirements in your state and follow the guidelines to install a point-of-use GFCI USB combo device where necessary.

Coordinate the Outlet Style with the Space

Style doesn’t have to be an afterthought when upgrading home outlets. Legrand features a wide variety of outlet options, including designer styles in the adorne® and radiant® Collections. These Collections offer a variety of device colors and coordinate wall plate colors to blend in or stand out in a room.

High Traffic Areas: Home Office, Kitchen

• Ideal spaces for higher powered outlets like a 65W Type-C USB
• Keep in mind locations that might require GFCI protection
• Powers devices like laptops and tablets
• Delivers true power for full-speed charging

Relaxation Spaces: Living Room, Bedroom

• Ideal location for 30W Type-C USB outlets
