I've put together a 5 volt "mod box" that uses rechargeable double AA's, just a basic battery box from radio shack for two bucks with a momentary switch rated for 2 amps molded into some empty space in the box with JB Weld painted black with Sharpie.
The battery connector, where the 510 atomizer screws in, was hack-sawed off a dead battery

4*AA's (~5.5 volts)
$2 battery box
$4 switch

Joye 510 atomizer, 3.2 ohms, $7
this is what they call high voltage, and it really burns the flavor and tastes bad if I leave it on for more than a few seconds, but just letting it heat up for a sec then taking a quick two or three second hit, and releasing the trigger just before i stop drawing, produces an exhale volume similar to a cigarette, and taking it in is pretty close too. the vapor is much warmer than a mini-cigarette battery.
this is just so much better than the starter kit i bought at the liquor store
closer to cigarette on the following points:
throat hit
volume of exhale
warmth of vapor
short inhales, more like a cigarette
...and i've even grown away from wanting the tobacco flavors already, running out of my sample of mango, everything i liked about a cigarette without the parts i didn't like...i find i want to vape much longer than i want to smoke, so i guess i have to get lower potency stuff next time.
I had sized this atomizer to 4.5 volts, but it hits so much better at 5 volts.
on a fresh charge it reads 5.7 v
