I really like charger functionality and the display is clear. The best one I've ever used. But a strong adapter needs to be used, otherwise the adapter will get hot enough. The screen is easy to read, it can be seen in many directions, the controls are easy to navigate and offer more information than many other chargers on the market Also, the charger does not make high-rise electrical noises that are very sensitive - a high-quality indicator. Generally, this charger complies with the high standards I expect in my devices.
