Why do many people seem to favor low-ohm coils?

Hehe, seriously though, I must have missed something... I vape on DCT (F16 single coils actually) at around 7-8 watts, I'm afraid to burn the stuff! Is it only on RBA's that you can go this high?

completely different setup... stick to the 7-8 watts...

the coils in your cartos are not intended to be vaped at that high a wattage.... did you even read this thread?

Uh... That's sort of what this whole thread is about...

Go back and read the thread... Because Watts alone doesn't tell you anything about heat... many factors go into it.

forgive me if i stray away from topic. but i got myself a mech mod so i could try the low ohm coil (high wattage) vape. i'm starting to wonder how are you guys able to maintain a good vape at those wattages

i hold my button for 1 second and i start getting hotspots (the kind that could pop the coil within another second). even when the coil worked perfectly fine on my regulated pv.

or is it cos im using 32 awg? i tried 32 awg twisted as well, not much luck either.

one setup was a 0.7 dual coil set up with a single 18650 and the other was a 2.0 ohm setup with stacked 18350s.

could anyone offer some advice? thanks in advance.

Actually, higher gauge wire is thinner and has more resistance than lower gauge wire.
E.g., 32AWG wire is thinner and has higher resistance than lower gauge 28AWG wire.

Isn't "gauge" parts of an inch? As in, 28 AWG is 1/28th of an inch in diameter? Or is there still some layer to US measuring units I can't comprehend? :D

ounze, liquid ounce, troy ounce... how do you guys cope?!

Somehow I'm not surprised. AWG, SWG.....

The diameter of a No. n AWG wire is:

Coping? I measure my coping mechanisms in Pints...

Walk before you run?

Sorry. Hotspots are indicative of a bad coil/wick setup. There are a ton of resources on rolling a wick and coil.

Honestly, don't shoot for extreme setups until you're confident in coil and wick building skills.

I must respectfully disagree. The boost circuit is always running on VV / VW devices 5 volt device or 6 volt device is already boosted to the max. It then uses pulse width modulation to regulate lower voltages. Take a look at PBusardos reviews on VV devices. He hooks them up to his oscilloscope and you can see with the exception of its highest setting being a flat line, lower voltages pulse between low and high voltages to give the correct voltage. So 3 ohms at 6 volts has a lower amp draw than a 1.5 ohm 4.25 (both being 12 watts).

Mechanical mods are the same way of course difference being its at the batterys limit 3.7ish.

I have to agree with you...If I put a 1.8ohm coil on my eVic, at say 8 watts, I get less battery life than putting a 2.6ohm coil at the same 8 watts. I was completely confused at first, so much so that I thought the eVic was being an idiot and calculating it wrong.

I try to remind myself that the battery is wanting to discharge (seeking balance). So, we aren't discharging the battery, or pulling amps; we are allowing it to do what it is inclined to. The less we "resist" that, the faster it can get it's job done.

I bet they hate the hell out of being charged...
