I have a friend that was interested in getting some vaping gear to quit analogs. He purchased an istick (20w), used it for about 2 weeks or so.
It was working great, but seems to be dying after just 2 weeks of use.
- display is blinking non stop. If I hold down the fire button, it reads "no atomizer" without blinking, then goes back to main display and starts blinking again (like a strobe)
- all atomizers I tested will read "atomizer short". they all work perfectly on every other mod I test.
- it's not holding charge. it seems possible to use it as pass thru (if it wasn't for atomizer short msg), but as soon as you unplug the usb, it goes out. been charging for over an hour, it sits there with the display blinking, the battery reads full as soon as you plug in the usb, and "low power" as soon as usb is unplugged.
I realize it's a long shot but, any suggestions? Anyone heard of similar issues before with the isticks?
Thanks!
Unfortunately, it seems that your friend got a bad iStick. Too many issues to start diagnosing over the internet, which may or may not be interrelated. I suggest your friend contact the vendor and RMA the bad one for a good one.

You know, I checked the 20 Watters and they come to only 24.00 shipped!
