E-Cigarette FAQ - Know When Your E-Cig Cartridge Is Empty
How can I tell when it is time to change my E-Cigarette Flavor Cartridge?
In most cases, you will be able to tell when it is time to change the cartridge (or cartomizer) on your PrimeVapor Electronic Cigarette by either a change in the taste you get or when the vapor production declines.
However, sometimes when the vapor production declines, it means that your battery is running down. We have found that the best way to check this is to put the Flavor Cartridge in question on a USB Passthru. Then you can know for sure if it is the battery or the cartridge that is at fault.
