This is one of the few times, it is NOT operator error. Unit is only 4 months old. After charging flawlessly, two days ago, it just wouldn't charge. At first I thought it was the tablet itself that wasn't charging, but then I observed the lightening bolt charging indicator go off the moment I moved the charger cable wire to check whether it was plugged into the outlet correctly.. After hours of frustration and experimentation, I realized that both the charger and the cable were completely useless. They had worn out after only 4 months of use. The slightest movement of either the charger or the cable would stop the charge.
After researching, I learned that I could use my iphone charger and and a cable I had from monoprice-- voila tablet was charged 100 percent!
