Three Democratic US senators are calling on the White House to follow the EU’s example and push the tech industry to adopt a single charging method for mobile devices. 

On Thursday, Sens. Ed Markey (D-Ma.), Bernie Sanders (I-VT), Elizabeth Warren (D-Ma.) sent a letter to US Commerce Secretary Gina Raimondo, urging her to develop a plan that addresses the lack of a universal charging method for today’s products. 

“We write regarding the economic and environmental harm inflicted by the consumer electronics industry’s failure to establish uniform charging accessory standards—a shortcoming that requires consumers to frequently change their charging accessories,” the senators wrote. 

The letter says the US should look to the EU’s recent agreement to require electronics vendors to adopt USB-C as a common charging method for smartphones, tablets, e-readers, and cameras by fall 2024. 

“We urge you to follow the EU’s lead by developing a comprehensive strategy to address unnecessary consumer costs, mitigate e-waste, and restore sanity and certainty to the process of purchasing new electronics,” the senators added. 

The senators themselves didn’t mention the USB-C charging method. Instead, their main complaint focuses on proprietary “specialized charging equipment and accessories” for new electronic devices. 

“This is not merely an annoyance; it can be a financial burden,” the senators wrote, adding: “Innovation should benefit consumers. It should not come at their expense, saddle them with incompatible accessories, and compel them to purchase different charging equipment for each device they own.”

Although not named in the letter, it’s clear enforcing a common charging method would affect Apple, which has long used its proprietary Lightning port on iPhones and iPads. But in its defense, Cupertino has previously said that requiring it to adopt USB-C would force Apple customers everywhere to buy additional accessories, generating more e-waste. 

Still, it looks like Apple will have no choice but to adopt USB-C for iPhones in Europe by 2024 when it comes to wired-based charging. In their letter, the Democratic senators added: “The EU has wisely acted in the public interest by taking on powerful technology companies over this consumer and environmental issue. The United States should do the same.” 

 The US Commerce Department didn’t immediately respond to a request for comment.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
