There are reasons why the EVOD V1 keeps getting recommended:
- the fixed 3.7V output 650ma battery can last ~4-6hrs (or more)
- with the stock 2.4Ohm or 2.2Ohm coils it will sip juice - run out of juice and battery about the same time
- the draw is fairly to very tight, great for "toodle puffing"
- the coil design is silly simple and actually works with %100VG
- the Silica wicked coils lifespan can be measured in WEEKS and not days, Silica does not break down like cotton (technically it is ceramic)
- the silly simple coil/atomizer design is equally silly easy to rebuild
- the cost of a "kit" and/or any of the parts are dirt cheap as the industry has moved to high output juice guzzling setups
One of my V1 EVOD's replaced the VMAX+Kayfun V4 I keep in the "throne room". A upgrade from the EVOD is the "EMOW" or Kanger Areotank+EVOD Twist. However much like the EVOD tanks, the EMOW/Areotank's are "eGo" mount and can easily be used on mods with only 510 threads with a inexpensive adapter.
In general if you are looking for +2.0 ohm coil/atomizer offerings you'll need to narrow your search to "eGo" type tanks as the overwhelming majority of the "510" type tanks were/are offered with mostly subohm and sub 2.0 ohm coils/atomizers.
Contrary to popular opinion "juice consumption" has little to do with "power" and "ohms" but rather SURFACE AREA in contact with the wick. The very thin (32-38AWG) wire used on the itty bitty "eGo" atomizers require very little power (very low mass) to heat up and vaporize very little juice simply because of the itty bitty "footprint" or contact area these coils have with the wick. (and the itty bitty wick)
In general, the diameter of the wire controls the resistance per foot. Larger diameter wire has less ohms per foot than smaller diameter wire. (of the same wire type) For the same number of windings and ID diameter the larger diameter wire will have more mass and surface area in contact with the wick requiring more wattage/power to heat up than smaller diameter wire.
To conclude if you want a juice/battery sipping setup you'll need to focus your attention on the 'eGo' type tanks which have itty bitty atomizers with itty bitty wires/coils in them. In general with few exceptions (like the 'cross over' Nautilus type tanks) tanks designed for the '510' connections will almost always use thicker wire and require more power.
(for fun and games (just because I could) I rebuilt a EVOD tank with NiFe70 37AWG and with a eGo/510 adapter ran it on a VTC-Mini in TC mode. Fun stuff)
