The low voltage cutoff on the iStick30 is 3.3V.The crucial point will be just before the istick shuts off from low battery. We don't know where that is - a cautious guess would be 3V. 30W at 3V would be 10A drawn from the battery (without allowing for inefficiencies in the istick, which could be, say, 5%).
I suspect that eleaf cut things pretty fine on the battery specs for the 30W - wouldn't be surprised if it's the same battery that the 20W had!
That said, if using less than the full 30W or if the cutoff is higher than 3V then you have something of a margin
The low voltage cutoff on the iStick30 is 3.3V.
Just awesome! I vape my Subtank Mini at .5 ohms and 22watts and can easily empty over 2 tanks before a recharge so far. Was going to go a full week before I post results to be more accurate. Doing the math I should have about 30% more mAh but it seems like much more. I'm thinking the 2200mAh they claim from factory may not be entirely accurate. Also, the iStick30 warns of low battery at 10% but at 3200mAh that gives a much more comfortable 10%So, the big question is how's the battery life so far?
