Up until yesterday I hadn't tried using the any of my X2s in pseudo Pass-through mode. Having 3 of the monsters I have never been without a charged one, I say pseudo merely because a true Pass-through (so I've been told) has no batteries and is completely reliant on household or otherwise a separate power supply. What I found was the X2 1300 that I used for the test had been used for the better part of 2 days and I figured this would best represent the conditions one would use this feature. To my surprise boy oh boy did it make a more than noticeable difference. At first I thought it may have been the juice (SI Cowboy) so I went through all of my 6 favorite juices which are all in new X2 Clearomizers and concluded that it truly was a big difference no matter the juice. I guess to some extent this makes perfect sense because I am using the recommended 1.5 amp charger from SI and the power is suitable for both vaping and Charging at the same time so one could conclude it must have more overall power than the X2 has even fully charged. Why you ask do I bother to point out the obvious? Well I didn't really give it much thought until yesterday but I will say it has made me a Frequent Flier of the X2 in pass-through mode. It's like getting those first few Vapes you get from a freshly charged battery all day long. Just thought this was worth sharing. Now I just need to find an extension cord long enough to reach from my house to the Mall... 
I'm thinking I see a car type charger in my future. One last thing, a question to those who have far more knowledge of these things, is there any chance this will hurt or diminish the longevity of the battery? If so I may just buy one to use exclusively for this purpose.
