Is It Practical to Build Homes with USB Power Outlets?

With technology continually advancing and gadgets becoming more integral to daily life, the question arises: is it practical to start building homes with USB power outlets?
After 39 years of experience working in homes, I have witnessed the rise and fall of various devices. One useful innovation that has caught my attention is the inclusion of USB and USB-C ports in outlets. These ports are convenient because the power bricks often burn out and are easily lost. However, before embracing this technology for entire homes, various factors need to be considered.

The Current State of USB Outlets

While USB and USB-C outlets are undoubtedly useful, they are currently quite expensive compared to standard receptacles. Equipping a house with these outlets might not be the most practical approach, especially given their cost. A compromise could be to strategically place a few of these outlets, which would be a reasonable solution until economies of scale bring prices down.

For DIY homeowners, installing these outlets is relatively simple. Replacing a standard receptacle with a USB/USB-C outlet is a straightforward task. However, there are a few things to keep in mind:

Do not and should never replace a GFCI (Ground Fault Circuit Interrupter) receptacle with a USB outlet. USB outlets are physically larger, so ensure the box you are installing one in has the necessary volume to fit the device and existing wiring. Some devices have only USB/C ports without electrical receptacles. Installing these outlets could cause a loss of standard receptacles, particularly on kitchen counters. This is an important consideration for strategic placement.

These outlets must be hardwired into each location, which means they could cost you a few hundred dollars to install around your house. It is possible to hardwire each location, but the installation process should be handled meticulously. Always turn off power at the fuse or breaker panel when working on an electrical circuit to prevent accidents.

The Challenges and Future of USB Outlets

The issue with USB outlets lies in their ever-changing standards. The outlets can be quite expensive, costing between $20 to $30 per piece. They need to be hardwired into each location, which means they can cost a few hundred dollars to install around your house. Additionally, the QC (Quick Charge) standards are continually evolving, with QC4.0 on the horizon. This means that outlets may become obsolete within a few years.

Four to five years ago, 1.0A USB plugs were the norm. Three years ago, they transitioned to 2.0 or 2.1A. One to two years ago, QC2.0 became the standard. Currently, QC3.0 is available, and QC4.0 is likely to follow. Unfortunately, despite the availability of the 1.0, 2.0, and 2.1A standards at big-box stores like Lowe's and Home Depot, the QC standards are now only available online. This can make them seem outdated the moment you install them.

Moreover, these USB outlets are a semi-permanent installation. While they are removable and easy to replace, removing and replacing each outlet could be a significant undertaking, involving cutting power throughout your house and a full day of work.

Considering these factors, building homes entirely with USB power outlets may not be the most practical solution. However, incorporating strategically placed USB outlets can offer a useful and practical solution until prices drop due to economies of scale and technological advancements.
