Same tank? Same wattage?I'm using 2 2100mah a day in the kbox vs the 30w istick that has a 2200 that lasts a day and a half..
Those efest batteries, I would not trust. They're rewraps of unknown origin, and they're damn sure not 38 amps. No 18650 battery is. That being said, what's the voltage cutoff on the kbox mini? Somewhere around 3.6 volts? If I'm right, that's the biggest reason you're getting less battery life.13 watts on kbox and 11 on istick.. Same tanks with both, Nautilus... The batteries are efest 38 amp 2100
Ok, That two watt difference makes a difference. And I missed @yuseffuuhler's point as well: the cut off voltage in the Kbox could be stealing some batt life too.13 watts on kbox and 11 on istick.. Same tanks with both, Nautilus... The batteries are efest 38 amp 2100
How long do you get from your Nautilus atomizer? Mine go for a week mostI have the same problem. 2 efest batteries a day on my Kbox. I vape around 6ml a day also using Nautilus minis on mine at 13 watts.
It further occurs to me, if they were free, they're probably also used. They go south and reduce their capacity over time and with recharging. Do you have a good charger that meters the mAh it puts in the battery each time it charges? (If not, you ought to think about getting one; I use the Xtar VC4, and recommend it, $30 online.) Two new married pairs of Samsung 25Rs from a reputable dealer just might fix your problem...Ya I was just wwonderin why the replaceable batteries wouldn't last as long.. Especially with the kbox being no screen.. But maybe it's an efest battery thing
