Are the 801s really 280mah?
So they last how long?
(My 510 batts only last a few hours if that... thinking of a Chuck. Can I get through TSA wuth a chuck? hmmmmm...)
I'm pretty sure that 801 batts are 280 mAh (as are KR808D-1s). It's difficult to specify how long they last; that varies considerably based on how many puffs you take per hour and how long (and strong) your puffs are. The most objective way to compare is with mAh. The 510 batt is 150 mAh; the 510 Mega batt is 280 mAh; the M702 I mentioned in a previous post here is 100 mAh; and there are batteries for the Chuck as high as 3000 mAh.
But really, I think a PCC levels the playing field. And the low mAh batts recharge much more quickly than the powerhouses.
The Chuck is about the same size as a Prodigy, which I had no problem taking through airport security a couple months ago (and vaping in the airport terminal). I also had had some concerns; I was afraid they might think it was a pipe bomb, but they didn't blink and eye. Just remove the batteries and keep them in a separate container (e.g., a baggie) within your carry-on. Find out more in the Travel section of the In Public sub-forum.
