150 watt box mod with internal battery or charging capability

[SissySpike]

guys, I don't want to have to replace batteries... I want to be able to charge it like the istick or mvp

You are picking the most inconvenient unreliable option. Yes up front there is a little more cost buying a charger and batteries but 4 batteries and unless you are a dummy you will never run out of power.

Id say 10 to one of the failures we here about are mods with on board chargers. Just be smart and get some sort of battery case I promise you will be much better off with replaceable batteries

But if you insist there is this http://www.gearbest.com/electronic-cigarettes/pp_162615.html
