Overall, the SMOK Morph 219 is a fantastic all in one kit. The new TF 2019 tank design provides good enough flavour and coil life to satisfy any stock coil vaper and the mod is absolutely brilliant.
Have you tried a different usb cable to be sure the usb cable is good?
Some mods plug in with the batteries in and some without I'm not sure which way the Smok Morph works.
You could try it the other way?
