just for you warp 
1. 6v+ devices all vape the same assuming they run the same voltage
2. 5v devices all vape the same assuming they run the same voltage
3. 3.7v devices all vape the same assuming they run the same voltage
More mAh = MORE BATTERY LIFE, not more overall power
Mods (Battery Tubes) Differ in the following ways:
1. Button Placement
2. Overall Design (1 piece, 2 piece, solder-free, adapters, etc...)
3. Voltages they run/Batteries they take
Moral Of The Story -- *Mods* as they are better known as, are simply battery holders. What makes them different is: design, the voltage they put through to the atomizer, batteries used as far as lifespan, and that is about it ...
