Last night I had 3 joyetech e-go T's that were all working fine. I used them with a drip tip and then started with a cartomizer a couple of days ago. This morning I got up and all three batteries are gone! They blink a little, but none can make smoke. I wiped off the connection surfaces with alcohol and cleaned all the atomizers, and no luck. They all show charged if you put them in the charger. Two are rechargeable and one is a USB passthrough. Does anybody know what might've caused it, or if there's a way to get them going again?
