Ok so a tank involves a 'hollowed out' atomizer with a hole punched in it, while a clearomizer IS the atomizer, but its just clear and refillable?
Different delivery systems:- note
bolded Atty, Carto, etc is the abbreviated form
Atomizer/
Atty- an element on to which 3-4 drops of juice is dripped- usually used for testing new juices because Attys are easy to clean. There are some diehard Atty users because it’s the best vape possible but very time consuming.
Cartridge/
Cart- a container with sponge (filled with juice) that is used with the Atty- juice drips on to Atty from filled cart and is vaporized- older outdated first “tank” system and prone to leaks unless the user is willing to buy extra seals and “fiddle” with them.
Cartomizer/
Carto- metal tube with stuffing and element. Holds anywhere from 1- 4 ml of juice. Carto is fully saturated and must be occasionally refilled when juice runs out. My Cartos last 1-2 weeks. Best Cartomizer I’ve found is the Smok Tech XL 1.7 single coil. Boge 2.0 ohm cartos will give a cooler vape. Always use single coil cartos with 3.3- 3.7 PVs for the best vape.
Carto+Tank- a Carto with 1 or 2 holes punched in it. Carto is than placed in a glass, metal or plastic tank which is filled with juice- juice saturates Carto by way of hole in Carto. My Cartos with a tank last, before tight draw occurs: light juices- 80-90 ml. dark juices- 50-60 ml. Cartos can be bought pre punched or a punching tool can be purchased.
Clearomizer (includes the Stardust and the Vivi Nova Tank)- a plastic or metal tank with a wick and element. A glass clearomizer is just about to be released. Contains NO stuffing. The rebuildable clearos come with heads (coil+ wick) that can be cheaply ($2.00) and easily (10 secs) replaced. When the head burns out simply unscrew the old head out and screw in new head- takes 10 secs. My Vivi Nova heads are lasting about 6-8 weeks BUT I wash the heads every few days and dry burn them. I've found the Vivi Nova to give the best draw. Some love them while others hate them.
If thats true, then the reason people choose the tank is to get more juice while refilling less often, and people use the clearomizer for the convenience?
Very well put except the head in Vivi Nova lasts about 8+ weeks depending on the type of juice- dark and/ or VG heavy juice requires more cleaning of the head. As I said though some love em while others don't.
For example, would the Volt X2 650 mah be considered an ego?
Not really because the Volt and all PVs from Smokeless Image use 808 threaded accessories.
No.
"Mod – Dual usage – Can be used to describe modifications to a device or accessory (such as getting more vapor production out of your cartridges) or a design variation of a commonly manufactured electronic cigarette. In the latter context, mods typically use larger rechargeable Lithium Ion batteries and allow the user longer battery life and increased vapor production but at the cost of the device looking like a traditional cigarette. Many mods will also allow the user to increase or decrease the voltage of their device to achieve optimal performance."
Are there 'mini tank' systems that are the same width as the battery?
Yes you can buy tanks that are pretty well the same width of the eGo Class. There are also cones that "smooth out" the transition from the battery to the tank. I have used both clearomizers and Vivi Nova Tanks and the Vivi is of far superior build quality.
My reco would be the Kgo 1100- 3.7 volts.
The next step up would be to Mini VV/ variable voltage. They fire from 3.3- 4.8 volts and are 510 threading. I own both Spinners and Twists and prefer the Spinner.
Vision Spinner comes in 400, 650, 900, 1100 and 1300 mah. Wide knurled voltage dial easy to turn and easy to read voltage markings. 1300 mah Spinner is the same size as 1000 Twist.
Both variable voltage PVs above fire from 3.3-4.8 volts.
I owned the Twists and now use them as backups because the dial was hard to turn and I could not clearly see the voltage markings.
1300 Vision Spinner- 113mm or ~4.4 inches long; 16MM WIDE, 2MM WIDER THAN A STANDARD EGO
1100 Vision Spinner- 119mm or ~4.75 inches long
1000 Twist- Length 120mm(4.75")/Diameter 14mm
