I’ll just go back to the vampire vape at 10ml I enjoyed that and I’m supposed to be using high VG juices in this. It’s just I had a few salts left over. I’ve only had this mod less than 2 days lol
I'm not sure if you understood my question.
It is not an issue if you use Nic Salts or Freebase nicotine as 'Nic Salt; and 'Freebase' refer to the type of nicotine in the juice.
What is relevant is the CONCENTRATION of the nicotine in the juice you are using which is shown in mg (milligrams)
All ready to vape juices that contain nicotine in the UK come in maximum sizes of 10ml (millilitres) - most of these bottles will be designed for MTL tanks which have tight airflow and run at low power settings so will contain higher concentrations of nicotine because MTL tanks only vaporise a small amount of juice (the less juice that is vaporised, the stronger the concentration of nicotine needed to be satisfying). Typical strengths will be 12 or 18mg for Freebase Juices and 10 or 20 mg for Nic Salt Juices.
Most 0mg juices are available in much larger (60ml, 120ml or even 240ml) sizes. It is legal to sell them in the UK because they do not contain nicotine. They are sold in 'shortfills', which means a 60ml bottle will actually contain 50ml so you can add a single 10ml 18mg Nicotine Shot to make 60ml of 3mg concentration (you can use a Freebase or Nic Salt Nicotine Shot depending on your preference).
The current tank you are using is designed to vaporise A LOT of juice and run at much higher power settings - if you use high nicotine juice in this you will stand a chance of making yourself ill with the amount of nicotine you are ingesting. Your tank is designed to be used with 3mg concentration juices (6mg at an absolute maximum).
I think the reason you are struggling with 40 Watt power settings is you are probably vaping much higher nicotine levels than you should be with that tank - it is also the reason it is getting expensive as you are currently blasting your way through small bottles that are designed to be vaped in tiny amounts in a low power tank.
Trying to turn down the power really low so you can vape MTL strength juices on your tank will not work - it isn't designed to run at typical MTL power settings or be frugal with juice. You have a direct to lung tank that is designed to run at higher power settings and blast its way through large amounts of lower nicotine strength juice - and that is what you should be using with that tank
Unfortunately, if you want to vape Vampire Vapes MTL Nic Salt Juices with high nicotine levels you need to buy an MTL tank that is specifically designed for strong juices (unless you can find lower powered MTL coils that will fit inside your current tank).
If you want to continue with the same tank and high powered coils you really should buy a shortfill juice and nic shots (I recommend you vape 3mg juices)
High nicotine and high powered tanks are a combination that could make you very ill, so if you currently are vaping this way I recommend you change as soon as possible.
