The purpose of this presentation is to present recent results obtained from the high pressure studies of the charge transport in ionic liquids. The experimental data from high pressure dielectric measurements will be analyzed in term of the density scaling concept [1,2].  As a result we will show that there is a relationship between intermolecular potential, thermodynamics and  electrical transport  properties of investigated ionic liquids.  In the second part of the presentation we will focus on the decoupling phenomenon between viscosity and dc-conductivity in protic ionic liquids at various temperature and pressure conditions [3-5]. Finally, the general rules governing the charge transport in this class of ionic liquids will be formulated.
