The Darwin made simple...
1. Screw on any atomizer with cart/tank/drip-tip, or a cartomizer. (make sure it is filled or primed with liquid).
2. Turn the dial down as low as it will go (4.2).
3. Push the button and vape.
4. If you want more/warmer vape, turn the power setting up gradually until you find a sweet spot for the liquid at hand.
5. Remember that sweet spot (power level number) for said liquid.
6. When the battery gets low, plug it up to charge...you can usually keep using the Darwin while it is charging. Or, just plug it up when you're sleeping and keep it fresh.
7. Stock up on adapters/extensions. They can extend the arm a little longer so more carto types work, and you can try anything and everything out there that will screw on a PV. In the least get a few 510>510 extensions if not a series of adapters. For me this combo of extensions is nice to have: 510>510, 510>901, 901>510, 901>801 With those four bits, it's hard to find any atty or carto that won't work on a Darwin. I almost never take the first 510>510 extension off my Darwin except to clean it out occasionally...it catches liquid and protects the original brass threads from wear and tear. Some folks might even like a
goose-neck extension. Drippers might even like the
Empire Drip Shield.
8. Enjoy the swinging arm! It doesn't have to be extended to a full 180 degrees for it to work. I.E. with it at 90 degrees, you can hold the Darwin different ways, and it's easy to set it down on a table/car-seat/etc. and not worry about it tipping over and such as that.
9. Now, lets pretend you have a Banana Nut Crab Berry Cake flavor that you liked alot at a power setting of 7. From now on, you can screw on pretty much any atty/carto and start with 7 and the 'heat' at the coils is going to be very close to the same. The Darwin will do everything it needs to do automatically to keep the coils operating at 7 watts. Of course slight adjustments of the dial might be in order for a new atty/carto to perform the best for you, but you can get pretty darn close just in remembering the 7.
10. You can flip the arm all the way down and it will turn the Darwin 'off'. You can just leave it on all the time...but it's nice to know it can be fully powered down if you want to stuff it in a pocket/purse/suitcase/etc. where it might misfire if the button gets pushed by accident.
