So I got a note core intelligence i2 charger 2014 version said it has 3 settings but I got it so while I vape an kill the battery I can put them in the charger an vape an the repeat the process yet it's been roughly 5 to 6 hrs an it finally is charged there is no buttons on the charger nothing in the instructions on how to change it cuz the battery charges a hell of a lot fast in the mod then in the charger wondering if it's on trickle charge or does the charger just figure out the battery an charge slow af
