The EU's common charger initiative does not end with wired USB charging as the bloc wants to harmonize interoperability requirements for wireless chargers to ensure interoperability tween devices from other suppliers and avoid the technological 'lock-in' effect by the end of 2024.To help the end user make more informed decisions about which power bricks to buy for their devices, the EU will also demand hardware companies equipped with chargers and electronics with appropriate labels that reflect the capabilities of new power bricks.The EU believes that universal chargers will help EU citizens to save up to €250 million per year on unnecessary power brick purchases and eliminate about 11,000 tonnes of e-waste annually in the block.But if it were to just to be a requirement that a powered-off laptop can be trickle charged over USB, in addition to its power brick... Then that would be no big deal.New 28V, 36V, and 48V fixed voltages enable up to 140W, 180W and 240W power levels, respectively.They still need to address the issue of the cable falling out where a screw lock is not practical."
