From now on, during the upgrade of eVic supreme firmware will pop up a choice box, letting you choose the firmware version, V1.1 or V2.1.
V1.1 is the upgrade version of the previous V1.0, which ameliorates the voltage and wattage adjustment.
V2.1 is a simplified Home screen version. Features of all-new firmware 2.1:
1. Bigger font, clearer display
2. Automatic adjustment mode
3. Operation is more simple
All new eVic Supreme released by Joyetech will be loaded V1.1 by default, and you can choose to switch to V2.1 by personal preference.
