Using new AW IMR 18350s, running an HH.357 1.5ohm atty at 4.7V, I get about 12 hours and 4mls of juice.
And yes, i know 4.7V is high to run a 1.5ohm atty, but i just cut from 24mg nic to 12mg nic and thats what it needs to provide similar throat hit.
Side note: I have noticed no extra cravings or differences in how i feel when i dropped from 24mg to 12mg Boba's.
