The protank 3 is a duel coil (I think they know many people just recoil the protank 1, 2 and mini heads) which I'd say needs more than a fix voltage ego style can provide. An ego style will be putting out 3.5-2.2 most of the time you are using it, they only output the 3.7 when fully charged.
The ipow (I don't know much about them) looks like it would be a good upgrade for you.
Thanks, I am a bit dubious about going to a dual coil set up, heard they drain the battery faster, warmer vape, etc. This correct?
However I do have 'the bug' and want to upgrade my Mini Protank 2 and eGo battery.
