Are HV attys more durable?

Is the wire thicker in a HV atty thus increasing the ohms or is it a longer wire with more loops?

That's a great question! The durability question is hard to answer, other than to say they are built to be more rugged. A 4.5 ohm atty, however, will not work on a regular batt. To compare durabilities well, the two different attys would have to vape well on the same batt, and that is often not possible. DSE510s have resistances of about 3.1 ohms, so higher than the regular (2.3-2.5 ohms), but less than the attys sold as HV (~4.5 ohms). The DSE510 attys will vape on regular batts or higher capacity 3.7V batts, and they are known to last much longer. A DSE510 atty will also vape on HV PVs, but the HV will make it die faster than the 3.7V PV. So the answer to your question is they are more durable, but the voltage of the PV can still shave off life from it.

Its like a Jeep. On normal roads, extremely rugged, and may last longer than a normal car. But off-road, which it is designed for, it might not.

As for how they actually raise the resistance, I do not know for sure...still researching it...but it seems like it depends on the manufacturer. Both ways you mention will work in theory of course, but there are also other materials than NiCr which have higher resistance for the same amount of wire material.

You can learn a lot from the local electronics wizards, like Vaporer, where they are building coils:
