Kodo yocan Charged until all lights blinked then turned off. When I double press nothing happens. When I hold the power the center light will turn on after 6 seconds, but nothing else happens

Answer:
Please click the fire button 5 times to turn it on.
If you can change the voltage level when you click the fire button 3 times.
The Yocan Kodo's fast charging speeds which allow the device to reach a full charge in just less than 30 minutes.
The indicator light will turn off once it is fully charged.

Please can you try to install a brand new vape cart.
