Hello Everyone and to start with a very happy new year to you all . I have a question and have tried to look for the answer on google and on ecf , but have not been able to find an answer , so i am now posting the question here , all help appreciated . I have a Reo Grand and love it , but at times i find it a bit big and heavy to carry ( specially when im wearing formals ) , i was considering a Reo mini and wanted to know how long the battery would last in it with a 2 ohm cartomizer . I do understand that it would totally depend on how much i vape , but just an approximate idea would help !! I only use a 2 ohm boge carto and on average go through about 3- 4 mil a day , on my grand ive never had a aw 18650 run out on me during the day . i do have brand new aw 14500's with me that i would throw on the mini if i got it .... all help appreciated and thank you for your replies in advance . wishing you well warm regards Sahil .
