Okay, I love passthroughs more than anything, but in a week and a half now I have 4 FRIED atomizers. Something is not right. Is this happening to other people????? I've even changed passthroughs and yet another one is fried today.
Lucky--this has happened to me till I saw my passthough was staying on for a few seconds after I stopped taking a draw. After changing out the passthrough, it stopped. But you say you have done that. Have you watched the light in the mirror to make sure it goes out as soon as you stop the draw? if so, then lets go to the power source. 4.5V 1 AMP will not fry the atomizer. What will fry it is over 1 amp--so what are you using for a power source? --------Sun
L7 you are just hardcore and the atomizers want to see you suffer.
How much are you vaping on the pass thru?
Have you been using the USB pass on your computer or some other power supply (battery pack, or some other weird mod)?
when running on usb power it is better to drip rather than use a cart. The cart when running dry is like taking the oil out of a car engine, you will fry the coil if its not wet.
