Mine did. As well as an AC to USB adapter, although I just plug the USB charger into the hub on my desk.I'll see around for those dual coil carto's. the site I ordered the kit from did not have those.
Does the ego T come with a usb charger?
I bought the eGo-T system with the type B attys and tanks and the 1000 mAh batteries.
Then I bought a few CE2s, eGo cartos, etc. to experiment.
Once you have the eGo batteries, you have the big part of any 510 or eGo system.
The eGo batteries will power both eGo and 510 attys and cartos.
Just note that the smaller 510 batteries use a different charger than the eGo batteries.
I haven't tried the dual coil mega cartos yet, as they're apparently only available one place, and they're pretty big to carry around. (The "normal" B tanks with a 1000 mAh battery is a pretty large stack for a shirt pocket, too. Most of my early leaks came from dropping the thing, and jarring the tank loose.)
You look like you're on the right track -- try a bunch of stuff and find what works for you. It's still pretty much the "wild west" era for vaping, so there are huge numbers of choices out there.
