Tube mod, 18650 battery with USB pass though that also charges the battery so a separate charger is not required as you could just plug in the mod when you went to bed. 3-6 volt VV, bigger OLED screen, puff counter, ohm meter, would show recommended voltage range of whatever you have attached to the battery. Battery indicator would be both a bar type, and the exact voltage left, could set it to show either, also would have an LED that would light when fired that you could change the color on to match the rest of your gear. It would have a removable head like the vision tox so you could use both a full size battery and a smaller battery to make it mini-lavatube sized.
That is a lot of features to pack into a couple buttons so the only button on the outside of the device would be the fire button and the volt up and down buttons, there would be a little door that would open up, or slide open that would hide the rest of the controls.
I really really really want a PV that is both full sized and mini in one.. but the tox has not gotten good reviews.
anyone have anything they would add to this?
