Awesome!! Small and vv! What is the battery life like?

I'm not sure Erika, just finished putting it together. The switched regulator is spec'ed with an efficiency up to 90%.

So I'm curious. Does it work?!

I was getting about 4 hours with moderate vaping and w/ no caps.

Now I got 6 hours with heavy to moderate use

and 7 1/2 hours with moderate usage with 100uf caps added

Been through about 4 or 5 charge cycles.

I was going to add a touch Mosfet with the DualCool N-Channel NexFet (CSD16325Q5C)

It would have been perfect under the 04050c board and w/ the contact point centered in the Rim of the .44 bullet casing,

but I didn't want to add any additional drain to the 900mah battery even if it is a slight drain.

I built the Mosfet circuit but opted not to install it. Maybe I'll do that another time and monitor the battery life difference.

Just put together another .44 mini booster.

This time with a touch switch and a voltage range that can handle Low resistance Dual Coil cartos.

Nice touch with the .44 rim. ...just a little extra conversation piece for the airport? :)

Ha, Ha, it's the piece that excepts the touch that would cause a bigger conversation... :yes
