I fell asleep and left my battery of my Yocan evolve 2020 version charging over night woke up and it blinks when I go to fire it up? Did I mess my battery up or did it not charge?

First of all, we don't recommend charging your device all over the night.
As for your Evolve battery problem, I think it didn't charge, and it's still at low battery status.Please use the cable that comes with the package box, and use a q-tip to clean the charge port.
If it still doesn't work, please contact our after-sale team to claim warranty.The email address is service@yocantech.com
