A wireless phone charger is built into the front console and provides up to 15W of power to charge Qi-enabled phones. Although the charging pad provides 15W of power, many phones will only accept a 7.5W charge using a Qi wireless charger, so the charging time for each phone will be different. Generally speaking, it will take between 2 to 3 hours to fully charge a cell phone in a Tesla, depending on the brand of phone, size of phone battery, etc.
