I have been using my nicostick with a USB connection for a couple of weeks now. I'm very impressed with the 510 performance at 5v. But one side affect that they all get using a manual switch at 5v, heat.
I was concerned that the atomizers may have a shorter life span but that doesn't seem to be the case. One thing you have to watch out for is sucking the cart dry.
I got to wondering just how hot the atty was getting. Then I remembered that I have an infrared heat gun I use to check the temp on my RC monster truck engine. So I vaped as I usually do and when I reached the point where I normally stop to allow it to cool down I shot the atty with the heat gun. The temp at the hottest point was 159 degrees F.
I was surprised that it was that hot!

PS: The temp was taken on the outside barrel of the atty, not the coil.
