i have just purchased a Yocan UNI Box Mod Oil Vaporizer Battery and already have issues with it. the 3 lights blink abnormally 3 times repeatedly after i try to ignite the ecig. the cartridge is tightened to the magnet which is inserted into the battery. i tried loosening the magnet attachment but it still isnt working. i dont know what the issue is but my ecig cartridge is brand new and my other new cartridges will not work with my battery either. the battery is fully charged as well.
As for the flashing 3 times issue, most of the time due to incorrect connection, and the UNI battery can't detect the vape cartridge.
Here are some tips for you.
1. Use a q-tip or cotton with isopropyl alcohol to clean the connect point.
2. Screw a brand new 510 adapter.
