Some fans ask question regarding Yocan Evolve charging light still blinks red.
He/Her told us that the Yocan Evolve and I charged it for about 2 hours and it still blinks red.

First of all, you have to know the indicator light of the charging device.
When you plug in the USB cable, the light will turn red.
And once it fully charged, the indicator light will be turn off.

Usually, the full charged time need to 1-2 hours. If you device still blinks red after you charged it 2 hours.
I think there are some problem with your device.
