The Ugreen charging adapter can replace the one you had or improve the charging of your mobile phone. The package does not include a cable, so you will need to use the one from your mobile phone. It supports fast charging Power Delivery, Quick Charge 2.0, Quick Charge 3.0, Quick Charge 4+, Quick Charge 4.0, which should be compatible with your mobile phone. Otherwise, your mobile phone will charge slowly, as with a conventional charger.
