Overheating Issue

[joey gibson]

So I have a cuboid 150 watt and I run it with an rda and within 3-5 vapes the rda itself gets extremely hot. whenever i go over 40 watts it tastes burnt. Can anyone help?

What sort of wire are you using? How sure are you everything is nicely 'built'?
Depending on your wire and wicking, you might get dry hits at 40w. Are you dripping on the coils or down the middle?

Your RDA top cap is just a hunk of (likely) metal which is going to conduct heat; RDAs themselves will get fairly hot during normal usage and some of this heat will transfer to the mod, as well. I don't want to suggest that we shouldn't be paying attention to how hot our toppers and devices are getting or that you shouldn't be concerned if your device itself seems overly hot, but "my RDA gets hot while vaping" is just a fact of using RDAs and not necessarily indicative of a problem.

That said, harsh hits are not good and a definite sign that something isn't working right, though it may be as simple as using more power than your coil can handle.

Besides what sort of wire type and gauge you are using, what is the resistance? 40W pushed through a 1.8ohm coil made with 30g wire is VERY different than 40W pumping through a .2 ohm made with 22g.

Hot legs can also cause harsh hits at any power level.

Few details to be able to help:

Wire gauge and type?
Ohm of the coils?
Specs? Wraps and ID?

Welcome and glad you joined.
In General higher ohm coils/lower wattage (generally MTL) vaping will:
Heat the coil slower, which may produce “less” vapor
Provide A “cooler” tasting vape, can produce more flavor
May use less E-Juice (<$ less money)
Prolong battery life (<$)
Prolong coil life (<$)
Prolong wick life (<$)
May result in less PV maintenance/Issues
Less irritation to non vapers
Aids stealth vaping
May be better in the long run healthwise (<$)
