Thanks Shawn I'll look into those. I was also looking at Smok G150. I'll have to check some reviews.
I have had the G150 for about 3 weeks now and, while it's nice, I would be reluctant to take it on such a trip.
1. Unreliability. I've noticed several issues that give me pause about the reliability and even safety of this device. Number one is charging. Sometimes it stops charging before its fully charged. It has definitely fried one of my usb wall plugs as well. Sometimes it seems to take a lot longer than it should to get fully charged. I definitely do not trust to charge it unattended . plus it could burn out my charger . .that would make me worry about taking it on an extended trip.
I also don't trust the resistance reader. Just last night, I removed the tank to fill it . .put it back on and got the "new coil" prompt . .but the coil resistance was way off. So I did it a few times .. screwed the tank on and off to see what G150 said the resistance was . .it was a .3 coil but I got a different reading every time ranging from .3 to .48.
Otherwise I really like it . .so these issues are kind of a bummer. It has a lot of power, fits good in the hand even though it's too heavy to pocket. I don't know if mine might be defective but I definitely would not purchase one right before a trip . .at the very least I'd want several weeks with it first to make sure everything is in order.
