With new 25W USB-C Fast Charge technology, the Samsung 25W USB-C Fast Charging Wall Charger charges your battery from zero to up to 50% in about 30 minutes, so you can spend less time connected to an outlet. The 25W USB-C Fast Charge wall charger will charge the Galaxy Note7 and other USB-C devices without the Fast Charging feature as well, with up to a 2-amp charging rate. The Samsung Wall Charger comes with a detachable USB to USB-C cable, which allows you to charge your phone from the USB port on your computer or other USB power source if you aren't near a wall outlet. You can sync and transfer files with your Galaxy or any other smartphone using the USB-C cable.
