so, can someone suggest a 5v, something that will go for 2 days to a week before i have to charge, and a charger, that fits the V4L cartos? and isn't some thing to piece together. (like a battery box, some switch and some regulator.)
a small flashlight thing is fine size too. I have been at the vaping for over a year, its great, but the battery thing is killing me.
so, any ideas?
