For the Aspire ZQ Vi pod, you can use both salt nicotine e-liquids and regular e-liquids. Salt nicotine e-liquids, as known, typically have a 50/50 VG/PG ratio and are generally produced in nicotine strengths ranging from 20mg to 50mg. Regular e-liquids, on the other hand, are produced with VG/PG ratios from 40/60 to 100/0 and nicotine strengths ranging from 0mg to 18mg. One of the most common questions we receive from those asking for ZQ Vi pod e-liquid recommendations is, "Can we use regular e-liquid?" Our answer is yes. With its cartridge featuring spiral airflow, it allows for comfortable use of e-liquids with a 70/30 VG/PG ratio. Among the low-nicotine e-liquids we've tried for the ZQ Vi, our recommended e-liquid varieties, in order of preference, are as follows: Yogi E-liquids, Dinner Lady E-liquids, Five Pawns E-liquids, Dragon Salt, and Kilo E-liquids.
