Refillable pod devices by Vapresso at 11 watts (medium).
To me the flavor of them versus full size gear is like the fidelity of an MP3 versus a compact disk; yeah you can tell a difference but not enough to go back to carrying larger electronics devices.
At $5+ per pack of smokes, for one day supply versus the 1 to 4 weeks from the $5 disposable pod tank.... rechargeable a few hundred times and once that stops I'm still mucho $ ahead. Recharging big ole 18650's means lug around a charger and spare batteries just in case. Carrying two pods is like carrying two inkpens...three, four...five is easy to do.
Not once has anybody who saw me vape a pod say "don't things explode?"
Fits in my shirt/trouser pocket. If the coil quits, just swap in a new one. Sometimes I'll fire up a Zenith clad mod for better flavor, just like sometimes I listen to a CD for better fidelity. But the day to day approach is keep it simple and portable.
