The battery should blink and turn off completely after it is connected and reaches 100% charge. If you do not have a cart in the Yocan UNI Mod it will blink and not allow it to fire. This is to prevent it from overheating without using it to make a cartridge fire. Place a cartridge in the battery and it should fire. Hope this helps!

@nokvdvy7 good suggestion, well done.

I'm not finding answers to why ALL 3 lights blink 3 times on my uni mod.
Where are the answers? Am I the only person who gets 3 lights blnking 3 times with no vapor?

Due to our engineer need more information about the light indicate status, not just blinking 3 times.
By the way, most of the blinking issues due to the connect error, try to reload a new oil cartridge, or magnetic adapter.
If your device still can't working, please make a short video to us.
I will forward it to our engineer team to assist you.
Happy vaping.

Yep same here. Not even 1 week old Yocan Regen.. first the 3 lights would flash 10 times. So I charged it. Now it does nothing when I plug it in, turn it on, or anything.
