10ml e liquids typically can last a few days depending on the type of vaper and the e-cigarette being used. With MTL tanks (Mouth to Lung) a 10ml e juice can be stretched to a week, this is due to the resistance of the coils and the higher nicotine content usually found in 10ml vape juices such as 10ml nicotine salt e juices.
So if you're someone who is vaping 10ml a day it may be the time that you start looking into short fill e liquids. Shortfilled vape juices are 60ml bottles filled with 50ml of e-liquid in a 0mg nicotine strength. Vapers then usually add in a 10ml shot of nicotine to reach their preferred strength.
