A battery with variable voltage will get you what you want. They are known as twists or a battery with adjustable voltage. The Zigzag rig you have does not have that. It's 3.7volts no matter what. When you increase the voltage, the coil gets hotter, producing more vapor - to a point, then it tastes burned. Yes, It's an ego style battery fixed at 3.7 volts.

+1 for this and feel free to PM me as well. I looked up your Zigzag kit online. The style of tank you have is want is more commonly known as a "Top Coil CE4" clearomizer. A couple years ago that was pretty much a staple tank and heavily used because at the time (2012-2013) it was the standard for beginners clearomizer tanks just like it is now. I still have some of those style of tanks but made by Innokin (out of one of my starter kits I bought on sale for the eGo batteries in it,) and another one that Kanger used to make with replaceable coils (known as the CE-X)
There is nothing wrong with starting on that tank but Zamazam is right that a "twist" eGo battery or a variable wattage device like an Eleaf Istick would be your next step when you're ready to upgrade. There are several versions of eGo Variable Voltage batteries available now a days and you'll want to google threw them to see if that is the route you want to go...or if you're serious about sticking with vaping which, from the sounds of your posts you are, you might want to consider skipping the next level of eGo and go straight for a beginners regulated Variable Wattage mod which will greatly open up your options for what kind of tank you can power and give you more flexibility in the future saving you money in the long run from "stepping up" one device at a time. If you want to go the eGo route than Discount Vapors has about the largest selection I can think of off the top of my head. If you want to do some research here and watch as many reviews on youtube as you can for the various box and tube regulated mods than 101vapes or Vaporbeast with their discount codes and a few other places may be where you want to start your shopping. The advantage to going with something like an Eleaf Istick 50 watt is that it's got a built in battery pack of 4400 mah that you charge with a USB cable like your phone so you don't have to buy external 18650 batteries and a charger for them out the starting gate, but can power sub ohm tanks (tanks with a resistance of less than 1 ohm,) to help give you that thicker vapor your seeking like the Kanger Subtank series or the Aspire Atlantis tanks or the Arctic Tank,,,those are the one's I like but your milage may vary.
The reason I bring up maybe skipping ahead to a regulated box or tube mod is because of the way you are describing the e-liquid you're seeking. E-liquid is made up of three or four basic components....PG (propylene glycol), VG (vegetable glycerin), flavoring, and if desired nicotine. Some liquids are nicotine free. Generally speaking PG is the thinner of two base ingredients. PG is generally a better flavor carrier and is responsible for most of the "throat hit" feeling of e-liquid...either on it's own or in conjunction with nicotine depending on your nic level and the quality of the ingredients of the liquid. VG is thicker and sweeter on it's own but does not carry flavor as well, it is responsible more for the vapor production in your liquid. Both base ingredients produce vapor but VG produces far more than PG on it's own. VG gives a much denser feeling vape but lacks the throat hit of PG even with high levels of nicotine mixed into it. Most, but not all flavoring is PG based...but there are some liquids that use a VG or alcohol based flavoring...this is necessary as some people are sensitive or allergic to PG and cannot vape liquids that are PG heavy or in some cases contain any PG at all.
Because of it's thicker and stickier nature, most older clearomizers like the one you're using and even some newer ones like the Nautilus and the Aerotank series can have a difficult time wicking some VG heavy liquids. There are exceptions like Alien Visions E-juice flavor Boba's Bounty, which is 100 percent VG to the best of my knowledge, but I was able to get it to wick in a Kanger Evod clearomizer but I had to build the coil a certain way and drill out the airflow holes in it to get it to wick properly. Generally, clearomizers like the one you're currently using like a 50/50 blend of the two at best or one with 60 percent or more PG. The newer sub ohm series of tanks have much larger juice flow ports and can handle much higher concentrations of VG in their stock coils where as before you would have had to modify them or use them in a rebuildable tank or dripping atomizer. Some people thin their VG heavy liquids out with a drop or two of distilled water for use in clearos like your but it takes some practice to get the mix right and as much as one drop extra can over thin the liquid and dilute the taste an vapor enough to make it unpleasant.
However, these sub ohm coils require devices with much higher power outputs to fire the subohm coils than generally put out by an eGo style battery. Some of these tanks, like the Kanger Subtank series, also have a 1.2 ohm coil option that can be fired on some eGo batteries but it is still recommended to use them on a higher powered device.
I am linking a couple threads to help explain the battery safety and power basics and about resistance and building. As these threads were written in response to other people's questions not all of the wording in them pertains to your specific question but the general knowledge in them is go to know never the less. I know you've been digging around the liquid threads and other parts of the forum and you are definately off to a good start. Any questions you have please as them in a thread or PM me directly if you'd like and if I can't answer them I can point you to who can. Once again, welcome to the VU and congrats on making the switch to vaping and best wishes on your vaping journey!
