An All-Day Vape is as the title describes: a vape you can take all day. This doesn't refer to the amount of time your vaping session will last, so you're not going to find any information here about devices or an e-liquid that will last all day. Instead, an All-Day Vape is a flavour and nicotine strength you can comfortably vape throughout the day without feeling under or overwhelmed by the sensation.
There's no All-Day Vape flavour. You can't go into a Vape Shop or visit an online vaping store to find All-Day Vape in the list of e-liquids. The term has come from the vaping community to describe a personal preference and help newcomers and experienced vapers alike find their perfect flavour and nicotine strength.
There's no definitive answer here. As we've said, All-Day Vapes are a personal preference, and so they'll vary from person to person.
If you're a vaping newcomer, an All-Day Vape may be an e-liquid with a low level of nicotine and a subtle flavour such as a Cherry flavoured e-liquid with a 0.8% nicotine strength. This should give you an experience that isn’t too overwhelming.
If you're an experienced vaper, you may find you like something with more impact. So maybe your All-Day Vape will be a 1.6% nicotine strength Classic Tobacco flavour. It's entirely up to you, your preference, and your level of vaping experience.
An All-Day Vape isn't a flavour you can buy, and it isn't something someone else can decide for you. You need to work it out for yourself, and find your perfect combination of flavour and nicotine strength so that you can comfortably vape during the course of the day.
