My vape will not turn back on


I have a wall charger for my mod and it kind of messed up and I plugged it back into my vape and what usually comes across the screen when I turn it on came up and then the screen went black. I tried taking the batteries out, using a new charger and nothing. It will not come back on. My batteries were about half way charged so I know they aren’t just dead. Please help


Are you charging your device through an external battery charger or through the microusb port? What device do you have? Is it a dual batteries device or a single battery device?
