Thank you to everyone who’s emailed questions to the Artisan site. The amount of interest in our product has made us really feel good. It turns out that you folks are our ego boosters.

The most common questions being asked are about battery life and longevity. The simple answer is that, at its max setting, the Ego Booster will reduce battery life by around 25%, so if you typically get 8 hours out of a battery before needing a recharge, using the Booster at the maximum setting will give you a little over 6 hours. As to battery longevity, time will tell, but we believe that, given the buffer between atty and battery that the Ego Booster provides, there will be little or no impact.

If those answers are enough for you, great. If you’re looking for more, I'll have to paraphrase Artisan John and roll out some math.

The capacity of a battery is determined by its stored charge, which is current multiplied by time, commonly measured in mAHr. A battery’s life (i.e. the time between charges) is determined by how much current is drawn from the battery over a given amount of time.

An atty is just like any heater; the amount of vapour it produces is a function of power and the more power it dissipates (measured in Watts of output), the more vapor it produces. The formula for calculating the power dissipated by an atty is I^2*R, where I is current and R is atty resistance.

(I have to use I^2 to represent I squared because I can't figure out how to superscript here.)

At its max setting, the Ego Booster increases power output from the atty by a little over 50%, so:

New Power = 150% of Old Power = 1.5*Old Power
or
Inew^2*R = 1.5*Iold^2*R.

The Rs cancel out, leaving:

Inew^2 = 1.5*Iold^2

If we take the square root of each side of the equation, we get:

Inew = 1.224*Iold

Thus the new current is 122.4% of the old current.

What this means is if you increase the current to the atty by 22.4%, power dissipated by the atty increases by 50%. Also, if you increase the current into the atty by 22.4%, then you will decrease the battery life by the exact same amount. So a fully Boosted battery’s life will be 77.6% of a non-Boosted battery’s life. Not a bad trade off considering the significant improvement in vapour and flavour provided by the Ego Booster.

So thanks for reading, and please keep the questions coming. Maybe next time we’ll convince Jill to step in front of the camera and you can get your answers from her instead of me.
