You need a Hybrid like the Zenesis or iHybrid or Juggernaut... etc... high end because CHina is not making these yet; its a new wave and they haven't caught up yet... they will.
The hybrids are designed with no connector (510) for one thing... their Gen atomizer is built right in, which gives more straight power from the batt - 1. no voltage interference of a connector 2. no electronics that limit amperage or protect against shorts; no wires 3. brass or other type of contact material for the button and pos. connection to batt which conducts power better as well.
Mechanical devices are made with a connector (510) for your 2nd party Genesis atomizers i.e DID etc ect but optimized like the hybrids.
These are all in the $250 range (hybrids), and 150 to 250 range (mechanicals; Poldiac, Gus, Caravela, Chi You, Roller, Dingo, ELA etc.)
Some are looking at cheap mechanicals ... you can look that up in the forums... "mechanicals for Genesis" but they are a compromise in quality and performance in the most part.
Thanks for all the great advice! What sort of device would I want to run a SLR coil?
I also tracked down the video you mentioned. This one, right?

I almost forgot to say even at the high prices these are HARD TO GET
