Well i am wanting to upgrade from my ego to something with more kick.Even with 2.0ohm cartomizers i find it to be somewhat lacking unless i use a very high pg /nic content
juice.But i was curious what to do should i go for a True 3.7v PV ,5v or VV.Still undecided but what i do know is that i would prefer it to be tube shaped and with batteries and charger to be under or around the 100 mark.So what would be some good options to look at .
The eGo has been metered underload at 3.2 and 3.4v at 3.4 with the 2.0ohm cartos you're vaping at @5.8Watts. If you get a true 3.7 Special Edition Riva - with the 2Ω boge cartos you'll be @6.8Watts. If you like dripping... with the cisco 306lr atty you can get to 7.7Watts on the eGo and 9.12Watts with the SE Riva.
Going to a 5 volt - you can get 10 watts with a 2.5ohm atty/carto but you're liable to knock out some flavor at that point and burning cartos is also a problem, I think, above 8.5Watts so using 2.8Ω and above is better for flavor and attys/carto life.
6 volts - you need to be around 3.5Ω and above to keep from killing flavor and attys.
I'd pick up an SE Riva at liberty flights and try it out. If you don't like it you can sell it at 90% of your cost on classifieds - perhap even up if you carry the shipping.
Above that - figure whether you want to stick with the tube type mods or go to box type and a
variable
voltage mod in either style might be in order. I have a Big Brother vv box mod that I vape at over 6 volts with a 4.2 joye atty @ 10W for dripping my coffee ejuice.
