I just bought the aspire cf sub yesterday. I plugged it in the original charger (only charger i have) last night and it still is not fully charged in the morning. When I DO unplug the vape it blinks blue 3 times, it has done this every time I have charged it. Yesterday after I purchased it, it died an hour or so later, i plugged it in and it still blinked 3 times, so no matter how long I charge it, it blinks three times and it dies really quickly. After I charged it yesterday, I literally hit it twice and then it was dead. Why would this problem be occurring? I've read multiple posts about using the original charger but I have done that and it's not working.
