The European Union might not be the only government body setting a common standard for device chargers. The Verge notes US senators Ed Markey, Elizabeth Warren and Bernie Sanders have sent a letter to Commerce Secretary Gina Raimondo calling on her department to develop a “comprehensive strategy” that would lead to a common charging standard. The EU acted in the “public interest” by settling on one port, the senators said, and the US ought to follow suit to reduce the environmental impact of chargers while improving convenience for users.

The politicians’ arguments largely mirrored the EU’s stance. A charger standard would theoretically reduce e-waste by letting people reuse existing cables and adapters for new devices. It could also help consumers money by sparing them from buying additional chargers, not to mention adding “sanity and certainty” to electronics shopping. This would prevent companies from locking you into proprietary cables that become obsolete, according to the group.
