Mine is definitely around 10 sec or more. All three of them, 1 auto, 2 manuals
I'm still questioning whether the X2 is fully charged. I always had to keep track of which usb/wall adapter was which. You are aware that Smokeless Image sells two types of usb wall adapters?
From my understanding, the X2 battery will charge only with the usb wall adapter that it came with. The one that ships with the X2 is a 1.5A "with 3x the power." The other is less. (I just looked on the website, it doesn't list the mAh of the lesser adapter, the one that ships with the X2 passthru is 1500mAh. I had both units and often got them confused. The X2 battery and its passthru cord are not recommended to be plugged into the computer usb port either.
I ended up giving away the less powerful wall units with my 78mm batteries and kept the 1.5v usb wall adaptor for my remaining X2's, so I no longer get them confused. I therefore am unable to compare them visually side by side. . I'm not sure if there is an easy way to tell them apart by looking at them together. Hard to tell from the website pics, they each were shot from a different angle.
The X2 doesn't ship with a wall adapter; that is sold separately. The only thing it ships with is the charging cable. Imagine posted that both of SI wall adapters will charge the X2, but to use it as a passthru while it is charging, you'll need the 1.5A (1500mA) charger.
I suggest manual batteries to everyone. I like the performance of the manual batteries 100x more than automatics.
haha, when you get your manual, don't forget to turn it on first: hit the button 5 times really fast; the 5-click on/off timing is a little persnickety, so you may have to play with it a few times to get it to turn on. But once you get the timing right, you're golden - the on/off function is really great to have (no accidental activation in your pocket). And once the unit is turned on, it's manual vaping as usual.sending mine back and getting a Manual 650 X2 instead.
-i charged mine fully before i used it. there was something wrong with it. it shouldnt cutoff after 4 or 5 seconds. Ill let you guys know when i get the "real deal".
