Why is that? From what I understand they should work fine with any battery over 440mah. You definitely don't want to use them with a standard battery though.
Let me take a stab at making this easy to understand. Pardon me while I put on my nerd cap
Yes, the dual-coil cartos DO work on eGo devices. I've tried them on different eGo batteries and they work perfectly. The flavor and TH I get from them, in these configs, is astounding. The very first time I set one up I was blown away! I am now ruined for life, happily ruined that is
Dual-coil cartos have 2 coils, like the name says. They are wired in parallel, which lowers the ohm rating. When you do this, you create a device that requires MORE watts to work. It's the same concept as with car stereo amplifiers. Because the dualies draw more power from the battery it will use up the power faster, meaning they will need to be recharged more often. This is why, I believe, people have been saying that dualies will eat up eGo's. The more often we have to recharge the battery, the shorter the overall life of that battery will SEEM.
Now, I say seem because in actuality all we are really doing is using up the battery faster because of more frequent charging. These batteries have a "life". That life depends on usage. More frequent usage means "shorter" life.
Example: Battery 1- 650mah battery using single coil standard resistence cartomizer. Let's say this battery gets standard vaping usage. The battery lasts 1 year with regular charging. At the end of it's "life" it requires charging more aften because it has used up the chemicals inside, meaning it won't hold a charge anymore.
Example: Battery 2- 650mah battery using dual-coil cartomizer. Same scenario as before, standard vaping usage. This battery requires charging more often because power consumption is greater. Remember, it requires more power to use a lower impedence. This battery lasts 9 months.
It boils down to this, if you want to use dual-coil cartomizers you should understand that it will appear as if the batteries don't last as long. The trade-off is seriously worth it to me. YMMV. I've had a few questions asked of me on how to improve the "power" of a PV. This is an inexpensive, around $2 or less, way to increase perfomance.
