Just an FYI. With a mech mod the only way to "fine tune" your vape is to change your coil (or build a new one). With a high vv/vw regulated mod (and its buck/boost circuitry) you can "fine tune" with a push of a button. On a mechanical mod your voltage drops as you vape. With a regulated mod this does not happen. Your first hit is just as good as your last hit.
The only mech mods I really enjoy vaping with these days are my Reos mods. All my other mechanicals require too much upkeep (for me) and I don't like the fall off in performance as the battery is discharged.
That said, if you are going to purchase your first mech mod I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader (if you are going to be rebuilding).
Baditudes Blogs. The blogs regarding battery safety & Ohm's Law are listed below:
BATTERIES
9. Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
17. Purple Efest Batteries Not As Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.
OHM'S LAW
14. Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.
16. Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
