It mainly depends on one's vaping pattern...
For instance I take long pulls,
very often bordering on 10 secs each, every 30/40 secs; that makes an average of maybe 15 seconds of continuous vaping per minute.
I use an AW IMR 2000 mAh as well, which at my usual 7W on 3ohm would last for about 1h20m of continuous vaping, or close to 500 (of my) puffs. Multiply that time by 4, add some breaks here and there, and it makes for some 7+ hours of actual vaping.
But I'm a chain vaper
... If you consider more 'normal' (?) vaping patterns, you can easily double that time.
This 10 second limit is one of the reasons I am surprisingly grabbing my GG clone all the time with a dual coil 1 ohm [total] load. For one It allows me to vape at 16 watts on a full battery and lasts pretty good down to 3.6 volts and starts to get weak on flavor. The BIGGEST reason for my preference is there is NO 10 second limit on the draw. My draws are close to 20 seconds and here is why.
I am trying to 'turn down the watts for batt life but thats going to take time.
I like to savor the flavor of my coffee and sometimes coffee/cinnamon flavored juice.
Witch brings up a not so commonly discussed Technique to e-cig smoking [vaping].
Typically I like to draw 3 times and sqwoosh my tongue up against the roof of my mouth forcing the vape out my nose, slowly but concentrated no inhale. Then after three of those I take one long draw in for the lungs. You won't believe how much more flavor you will savor vaping this way, sort of how a pipe or cigar smoker smokes for the first 3 pulls then a cigarette smokers technique for the last pull. All done wile holding the button down ONCE the whole time!!!!!. Doing this I can cut my flavor expenses in half [I'm a DIY juice-maker]. Use less flavor juice percentage.
I can not do this with a LavaTube or any other computer controlled power supply [MOD] with a 10 second limit.
However this vape business is moving faster then the computer business and like the new
DNA 20 D Chip and it's 20 watt max,
DNA20D By Evolv click on the stats link.
Read the specs here the voltage outputs have some confusion.
I read into the Normal voltage column as yielding no more then the 15 watts some others are already achieving.
Then the Vmax 5 amp super stuff at vapor beast dot com.
None of witch has an opt out of the 10 second limit.
I love electronic gadgets but my simple mechanical wins the war of
No Nanny Bovine Scatology just vape and forget about it.
Use my LavaTube for experiments, ohms check voltage optimum search tests
when rewinding my coils. After that I pop it on the mechanical and enjoy no nanny vaping.
Havent found a computer chip controller out there yet that fits my taste. One I can access with a flash program to eliminate some things I don't want will get my business.
