Keep looking for more info on your problem. I came home from work (tired as hell), and put my month-old 1000 Twist on charge and started using my backup. After an hour, I saw the charger LED was green and took the Twist off of charge.
When I put on a Boge LR cartomiser it flashed
three times. When I hit the fire button it flashed at least a dozen times. After trying two other cartomisers, I put it back on charge and the green charging LED did not flicker. (I think it may not have been charging when I first put it on charge tonight)
While looking up information online (and finding this
thread) I picked up the Twist again. As I picked it up, I saw the white LED was flashing at least twice. When I hit the button to fire it, it fired. With the same carto, it vapes fine.
When I unscrewed the carto to put on another, I again saw the three flashes. I screwed it back on, and it works. I just put it on charge again (it's not hot) and it is charging. (red LED, flickers green every 10 seconds or so)
I have no clue what is going on with this thing. When it hits full charge I will update this post.
On a side note, the 650 eGo-C Upgrade (with mini-USB passthrough) in unregulated power seems to
vape around 4.2 at full charge. This is my backup unit and I love it for it's small size. (only an inch longer than a cartomiser with a drip tip)
