Welcome to the wonderful world of
vaping!
When I first started, the difference in draws was a drag - lol
I learned to draw slow and it made all the difference.
Another thing that was different was pacing myself as analogues eventually burn up but when do you take a break from vaping?!
The battery thing is why I have several batteries charged up and just switch as needed.
Have fun checking out the forty zillion other posts to this forum...it is awesome.
Vape On!
