For the vast majority of new starter kit, we recommend 70% VG (read more about VG here) and a maximum of 6mg nicotine strength to get a nice experience and feel of the vape. New e-cigarettes generally use sub-ohm coils, which has a stronger effect than the older devices meaning that you’ll get more nicotine faster, and therefore need a lower strength on the e-juice.
This also applies if you are upgrading from an older e-cigarette and already has e-juice with 12/18/24mg nicotine, then you also need to buy e-juice with a lower nicotine strength. Do you however want it stronger, you can certainly try 12mg or stronger.
If you are using rebuildables, or are looking to, we recommend 3mg for RDA and 3 or 6mg for RTA and RDA.
