I got my Little Chuck yesterday, put in a newly charged Utlrafire 16340 880 mAh, and then proceeded to chain-vape to see how long it would go with heavy usage - it lasted abut 3.5 hours. I also have some 18350 batteries - higher mAh - and used fairly heavily last night and this morning - probably 3 hour - and then it lasted all day for me at work, where I have to go outside, so don't vape nearly as hard.
I just bought a multimeter, but haven't opened it yet. I'll do that Saturday so I can measure the voltage on my batteries a they come off the charger, and be able to test the 901 atomizers that don't seem to be working before bothering to try a thorough cleaning on the several I want to test - no sense in cleaning a dead atty!
I also have a Big Chuck, and get 3+ hours on my RCR123A 3v batteries vaping 6 volts. And my 18650 batteries at 3.7 v definitely last more than a full day.
