The Prodigy V3, an American-made PV from PureSmoker.com, is a truly fine piece of hardware. Except for a delrin-plastic insulator disk in the mechanical switch assembly, this drip-friendly mod is made entirely of stainless steel, which is very precisely machined and beautifully finished. The switch assembly screws in at the bottom of the tube and has a cleverly-designed locking feature. All the V3s parts, including the switch components, are brilliantly simple and heavy-duty. The unit comes with a choice of adapters for 510, 801, or Ace/901 atomizers. The full kit includes four RCR123a lithium-ion batteries and a charger. The V3 operates with two RCR123a batteries that supply a total of 6 volts. It can also be used with a single 3.7 or 3-volt battery (see below).
Ive been using a satin-finished Prodigy V3 with a 510 adapter for about three weeks. They also come in a sandblasted finish. I have found that some e-liquids don't taste as good when vaped at 6 volts, and some taste better. They all have had an increased warmth and throat hit. In general, a vape at 6 volts is a sensational experience.
But regular 510 atomizers are not designed for such high voltage. Even though I kept the atomizers wet and my drags short and reasonably well spaced in an effort to minimize overheating, the atties burned out quickly, each one lasting maybe a day or two.
Fortunately there are solutions to this problem. The best option is to use only high-resistance atomizers at 6 volts. The V3 still produces tremendous amounts of warm vapor with these, but the atomizers hold up much longer. Not sure just how much longer; I havent popped one yet.
Another solution is to use a regular atomizer with a single 3.7-volt battery instead of two 3-volt batteries. The battery to use is the AW P17670 (protected) battery, which is available directly from PureSmoker at the same price as sold by Lighthound.com. Not just any 17670 protected battery will do because most of them wont fit in the V3. Even the AW P17670 just barely fits. It will only go in from the adapter end. They have foil sticker labels on them that I pull off (and use Goo Gone to remove the gummy residue). Even these stickers can interfere with clearance. These batteries do require a different charger from the 3-volt batteries, of course.
It would appear that using a 3.7-volt battery with a regular atomizer in a V3 would defeat the purpose of using a high-voltage PV, but it doesnt entirely. The eGo, for example, is a 3.7-volt device. Its a great one too; a current standard of e-cig excellence. But the eGo battery actually puts out a little less than 3.7 volts. So the V3 with a 3.7 battery produces more vapor than the eGo.
Some who use the V3 with a 3.7-volt battery use low-resistance atomizers to approximate the high voltage effect. I havent tried that because I dont like low-resistance atomizers, but there is a place for them I might try going, for the sake of experimentation. It regards a third solution to the 6-volt/regular atomizer problem.
The V3 can be operated at 3 volts by substituting a dummy spacer for one of the RCR123a batteries. I got one at BatteryJunction.com to experiment with. Using a regular atomizer at 3 volts does work, but you dont get a very satisfying volume of vapor. A low-resistance atomizer would compensate for the decreased voltage.
Regardless of what battery/atomizer combination might be best for a particular vaper, what I like most fundamentally about the V3 aside from its intrinsic quality and versatility is that, like other mods, it uses non-proprietary batteries.
