No, surprisingly, the brand-new Class 345 trains used on London's Elizabeth line do not have USB ports or power outlets at the seats for passengers to use. While the line is a marvel of 21st-century engineering and features high-speed Wi-Fi and air conditioning, the decision was made during the design phase to omit chargers to maximize standing space and reduce maintenance complexity for what is essentially a high-frequency commuter service rather than a long-distance train. In 2026, this remains a point of minor frustration for travelers heading to Heathrow who need a quick battery boost. To avoid getting stranded with a dead phone, many commuters carry a compact portable charger like the Anker PowerCore 10K, which is small enough to fit in a pocket but powerful enough to charge a smartphone twice. While the stations themselves have some limited power points in waiting areas, you should definitely not expect to find a "plug-in" spot once you board the purple trains.
