I'm not sure if you're talking the standard 510 to eGo, but the button is slightly closer to your mouth on the eGo, and a sliver closer with a standard cartomizer on the eGo.is the cartomizer setup the same overall length as a standard atty+cartridge? one thing I wish was different about the 510 is that the manual button is so far forward. would feel much more natural if the button was closer to the mouthpiece end.
I know the eGo batt will not fit the standard 510 pcc........will it charge from the 510 wall charger or if I get an ego battery will I also have to have a separate charger?
A separate charger would benefit. The standard 510 charger will charge it slower.
One question . . . do you know anybody who might like to try vaping? If so, it may benefit you to just get an eGo kit. You could resell or loan-off one of the kits to somebody who would like to start. A lot of people have written that they actually prefer different pvs for different situations . . . in the car, in bed, in public, on long trips, at work . . . . LOL, I've been vaping for about a month. I have 2 eGo batts, 5 510 batts, 7 510 attys, 12 510 cartos, and tons of cartridges and juices. I am still about even with what I spent on cigarettes. I don't see it as too much of a loss, and I use them for different things.
