Power was my first "irritation point"... too many little
batteries to keep charged. With the power upgrade came delivery improvements. Cartos to CE4S's to EVOD's to ProTanks...
Recently purchased a Private V2 mech mod... contemplating which direction to go with an RBA and which stinkin
batteries to buy for the V2.
My psychosis still centers on batteries. I now have two VV Pass-Thru devices which I use at my desk and in my vehicle. Batteries only required when I'm mobile away from a power source. These have helped me with my dislike of batteries and concerns with their volatility.
My next want is a Pass-Thru with the more complex internals like a Provari... I know they make a pass-thru you can use in the Provari tube... but I find the $69.95 price for it combined with the Mod and batteries and chargers a big rip-off
