OMG THE DAY AFTER I ORDER MY ALFA.
Haha that's usually how it goes.
Well, each session is 10 minutes so you can assume around 5 or 6 sessions with a 1 hour charge. Also the ability to have charged batteries ready to go means it would last a few hours of continuous use.
Depending on bowl size my regular sessions usually last 12-15 min with other vapes (.25g of herb) and even longer if you're a "temp stepper". I understand there are other batteries on back up. I'm just expressing my personal opinion
