I've been lurking for a bit and figured I'd finally post with a few questions that I can't seem to find answers to (although I'm sure they might be here somewhere...
).
Here's the deal-- I just got my DSE901 kit a few days ago after reading here that it was a good one to start with. So far so good but I only have 2 atomizers and 2 batteries so I should probably order some of that right now...I have 40ml total of juice and have much more on the way already plus a case. I didn't think at first about the logistics of lugging around all the "stuff" so I'm anxious to get that, ha!
Okay so my questions are:
I don't quite understand what a "manual switch" does or why it would be a good thing.
I do get why the USB passthrough would be good but wonder if that's more for heavier users?
I might be interested in ordering some more prefilled carts to have on hand...not every place seems to have these...is there any recommended supplier?
If you get a car charger is it like a passthrough where you can use the device while it's plugged in?
Thanks so much for all the help. I haven't touched an analog since I got my starter package.
Or even wanted too! This is way more fun although I think I might add two new addictions-- vaping plus shopping for vaping stuff. 
Just gotta get my husband on board with it...he's a heavy smoker...but I'm not gonna push him...just hoping it rubs off on him some...
Thanks for the help.
