One of my students said that her Prime calculator battery was dead and it wouldn't charge. I plugged it into a computer and it seemed to charge fine. I suspected that she was using a fast charger >5volts. I recommended that she use a computer or the small charger and she's been fine since. Fortunately, it appears that no harm was done to the calculator.
