Simply put, this mean the vapour goes directly into your lungs without lingering in your mouth. DTL isn’t usually an entry point for new vapers as the hit can be more intense than MTL, which can be a little off putting for first time vapers, however over time once you’ve become experienced you may want to give DTL a try. DTL also provides flumes of vapour, or more commonly known as ‘cloud chasing’, which for some is part of the enjoyment of vaping. Sub ohm devices are DTL and will usually be a bigger device as they need a larger battery and often have settings which allow you to alter the air flow to satisfy your preference.
High VG e-liquids are needed for DTL devices and as the hit is more intense than MTL you’ll usually find the maximum nicotine level available will be lower than high PG e-liquids.
