Samsung Semiconductor has developed a brand-new chip that enables smartphones to wirelessly charge at up to 50 watts. This chip supports the Qi 2.2 standard and promises maximum compatibility, also with magnetic chargers.https://www.notebookcheck.net/Samsung-unveils-Qi-2-2-chip-for-50W-wireless-charging-and-magnetic-chargers.947801.0.html
