I am using a 510 manual from innovapor. I love the throat hit, the vapor , the temperature of the vapor. EVERYTHING. But, after vaping for a very little while the power seems to die down. I have several different batteries. I think I just need a stronger battery overall. Is this possible in the 510? Whats available if anything. I've ordered a 5v. passthrough but that wont help me when I'm on my horse! Thanks for any info. Tried to put this question on the veterans forum but they wont let me yet.
