some help for a noob

[bundy325]

hey guys sorry for the lack of punctuation
i have a good amount of beer in me

now i got a mvp 2.0 today from a local vape shop for around 40$ last one to the girl gave me a good deal plus flirting with her kinda helped lol

now it came with a iclear 13b tank but my questions are
what is the point of being able to change the wattage and voltage?

i got some juice from the same store if i go over 3.5 v i get a burned taste if i go over 6W also i get a burned taste from the iclear 13b
now is it the juice or ?
i also have a ego tank i think thats what it is and i get the same results

now maybe its not functioning correctly but i have a ego tank and the ohms is suppose to be 1.8ohm well that what it says on the coil but when i try to read it on the mvp it says 2.0

so happy i got ahold of the mvp for a good price i had a ego c usb passthrough that was giving me headaches already
im not a heavy vapor but i wanted something reliable plus which is a big bonus before going to my local best buy to look for a portable battery brick due to using my phone alot its like the best of both worlds thats what pretty much sold me on the mvp was the ability to charge my phone

thank you guys in advance

I'll give this a limited shot for you
Changing the V or the W can affect the flavor - make it more or less pronounced, or bring out the subtle nuances in a more complex juice.
Generally, you should start out at the lowest setting (volts or watts) and then gradually increase the voltage or power until you hit your "sweet spot" (best flavor for your tastes). It will be different with each flavor and maker you vape. There is no reason to push your device to max power. Higher settings are more useful for sub-ohm vaping. If you're using standard, pre-built coils, you probably won't need the higher settings.
Next, factory built coils are rated at standard resistances, but are usually not exactly on target, so it's kinda normal to see a small variance in ohm reading from whatever they're marked as being. Nothing to be concerned with there.
