Is that one of the new mini's (2.0, 2.1) with the larger battery capacity ? I've got an older mini, and love it, but the 14500 battery only lasts about 12 hours, or about 2ml of vaping. I have been wondering how the newer mini's hold up over the course of a long day.
It's the 2.1, that takes an 18490/18500. Did you mean 2hours? 12 hours would be rather good!
The 2.1 also have a larger drip well, so you can use all the popular Reo rba's on it.
