How long do the batteries last on a single charge?

veiik batteries are designed and manufactured using the latest lithium-ion and lithium-polymer technology. How long a battery last depends on a number of different factors, however the most notable variable is a battery's capacity or milli Amp hour (mAh). Veiik batteries can range in capacity, starting with 180mAh and reaching higher. While we cannot list each of our batteries expected life, a good frame of reference is the following: a 650mAh battery, will last approximately 650 puffs before needing to be recharged, 1100mAh approximately 1100 puffs, 200mAh will approximately be 200 puffs etc. However, actual battery life can vary wildly depending on the cartridge being used. Please keep in mind that these are all approximate calculations and each user will have varied results based on usage and age of battery.
