Frying a cartomizer

[Blue Sage]

It has been a while since dealing directly with my electrical training. However my wife has been using a Vision Nano Clearomizer on her Blu ecig. (She's happy with her Blu for her purposes.) From what I understand that clearomizer is 1.8 ohm. And the Blu fluctuates from 4.2V down to 3.3V.

If I'm correct in thinking, she should never use the clearomizer just after her device was charged. Since at 4.2V she'll be using 9.8W and 2.3 Amps. The Wattage is outside the known sweet point and the Amps is liable to fry it. Her optimal point for continued use would be for using the clearomizer after she's already used the battery for a while. I haven't actually checked yet, but I imagine that the battery in the PCC never reaches 4.2V

Does this seem right?

There is no way in hell that the blu battery even comes close to frying any cartomizer (unless dry and empty) or clearomizer whatsoever. With it's puny 90 mAh if the blu pushes 4.2v it will do so for a very (VERY) brief period of time.

Anyways, 10 watts will not burn anything, might get dry hits, but nothing will actually burn.

When you think of a charged battery being at 4.2 volts this is with no load (current draw) on it. When you draw current from the battery some voltage drops across the internal resistance of the battery so that it lowers the actual output voltage. Lower capacity batteries have a higher internal resistance and can't supply as much current. Many people don't understand the part about batteries having internal resistance. Also, when your battery starts to lose charge the internal resistance goes up which causes more voltage drop internally and also less current output

The really high drain 18650 type batteries have a really low internal resistance to allow the amount of current flow they can provide but the resistance still goes up as the charge drains.
