I started my vaping with a cig-a-like,killed its battery in 4 hours (as I chain-vaped constantly)I then got 2 ego+clearomizers & was happily chugging through 30ml in 2 weeks(18mg)In steps an RDA so I was forced to build a dual 18650 celled box to power it & worked my way down to 0.4 ohms before deciding RDA's were spawn of the devil & resumed chuffing away on an Aga-S with dual coils & extra holes drilled in the cap.I had by then bought a Vamo and was happy with my 18mg juices in clearo's at no more than 9 watts.I bought a few other tank type devices (Russian 91%,RSST etc)but still vaped 18mg @ no more than 10 watts.
Then decided to retry the RDA's,so out came the tools and the Chinese clone RDA was duly stabbed with an assortment of ever larger drills & the 18650's were now VTC4's(instead of recycled laptop cells)& the tube mod was now Kylin(shit)Sigelie(shit)and copper clone(awesome)and batteries were now including 26650's in a Hades clone(shit) Then I happened on a box mod built using lipo cells so did a little research & bought a heap of 1000 mah lipo cells & a couple of Hammond enclosures.An hour later,I was now vaping an RDA @ 0.34 ohms and the box mod allowed this kind of output for easily 30 hours of chain-vaping. This convinced me to switch to RDA's full time,and the DIY juice production allowed large clouds of tasty vapour & I noticed I was finally getting nicotine "rushes" so could lower the nicotine content in my juices & not suffer cranky behaviour.The lipo mod production went a little mental in the last few months & I'd bought some physically large cells so needed a huge box/enclosure of some kind to house them.Enter 1 plastic box that is almost large enough to live in,and some jiggerypokery with 2.5mm thick cabling/110A rated mosfet and the result is a constant 8.2+ volts @ 0.78 ohms = 90+ watts cutoff where I recharge the cells so I can vape over 12 hours @ 110+ watts.Yes I do get through a lot of juice(upto 20ml per day)Yes I do look like I'm driving a traction engine.Yes I do get stared at(so fuck)Yes I do enjoy it.Yes I do tend to melt the insulators on centre-pins(clone drippers so easy to replace)cheap to modify,to get even more vapour.My minds eye sees the fog & is sated,even if there is no nicotine in the juice. I am so pleased with the results of this box,I intend to build another with variable power,and another with even higher output as each increase in voltage is reducing the current drawn & thus will enable me to revert back to the 1000 mah cells in smaller enclosures,but still get long runtimes.
As for anyone else's preferred wattage,if you're getting satisfaction from 1 watt or 1 million watts doesn't matter.The only thing that matters is you're not smoking.
