Since first post, I have spent 4 or 5 more hours reading about them. It seems most people online like the ipv3, then a few the sigelei, and next to none like the clouper. I seem to change my mind on what I am going to get with every post I read.
But I keep coming back to the clouper, for one reason. The output voltage on the clouper t8 is 5.6 to 14 volt. Both the others it is 1 to 7 volt.
The main reason I want to get a high wattage regulated device is so I can build any size coil and still get a strong vape. If I am understanding ohms law, at 7 volts you would still need to low sub ohm(.33) just to get 150watts, even the sigelei would need .5 ohm atty to get its 100 watts. The cloupors `14 volt could get 150 watts at 1 3 ohm.
On the low side the clouper gets hammered. The other two should be able to run my kayfun, nautalus, etc. But I would have to get pretty high ohm attys to make the clouper work with them. But this part doesn't matter much, since I have other mods to use with them.
I'm not seeing many people mentioning the low voltage output on the sigelei, or the ipv3. So that makes me think I am doing something way wrong, either with my math, or with what "output voltage" means. So any clarification on this would be appreciated.
