If your da b vape device have similar problem, please read on.
I bought one of these literally a few hours ago from a retailer and already it won’t turn on after I already made sure it was charged
Any indicator light when you plugged the cable?
Do you have check the charge port?
If you have checked above issues, the cable is OK, I think get a malmanufacturing item.
