    I tried a couple of other power supplies recommended by the sales people (who didn't know what they were talking about). Finally, I found someone who really knew what they were talking about and after hearing what my needs were they recommended this power supply. I couldn't be happier. It is powerful enough to charge my phone and my sons' tablet even while being used. It is really great.
