Thats the set up i want! Do the Kr808 cartos just screw on or do you need and adapter? and why Kr's? what is that pass through your using? thanks for answering all the questions it can be confusing getting started.
Thanks for your comments, mrp! I couldn't be happier (at this time) with my current setup.
The KR808D-1 cartos do screw on, but you will need a 510-battery to 808/901-atomizer adapter in order to use them with 510 and eGo batteries. I bought my adapters from goodprophets.com (they ship from PA) for 99 cents each, and that's the cheapest price I know of (for adapters and drip tips). The adapters work very well, and the only thing I had to do was use a small screwdriver to turn the slot on the round adapter connector counterclockwise two full turns to lift the round connecter out enough to make a better connection with the round connector on my eGo batteries.
KR808D-1 cartos tend to produce more flavor and vapor than the Boge 510 cartos, so that's why I decided to switch to them. I'm still using both Boge and KR808 cartos, but when I placed a recent order for more cartos, I only ordered KR808D-1s (from litecigusa.net).
I have seven passthroughs that I bought during my first month as a vaper, thinking they would be handy to have at the computer, but then I found out that passthroughs can be used anywhere that has a wall plug available -- and it's not a good idea to plug passthroughs into a computer USB port, because the amp output from the motherboard is not enough to power passthroughs effectively, so I bought five 2amp AC to USB wall adapters at madvapes.com. I have passthroughs plugged in at my bed, my bedroom desk, my office desk, and in my car (using a 2amp Car to USB adapter from madvapes.com).
Since I bought all of this stuff, I've discovered that I'd rather use eGo batteries to vape, instead of the passthroughs, so I rarely use the passthroughs anymore. And that's why I've been buying more eGo spare batteries lately. The performance of the eGo battery is much better than the performance of any passthrough I've tried (have tried three different brands). The passthroughs output 5 volts, which was causing more mouth pain when using them due to more heat hitting the inside of my mouth, as compared to the 3.2 volt eGo batteries.
