Product review: GMYLE(R) 40W 8A 5 Port USB Desktop Power Charger


I really like this charger. It is quite compact for being able to charge 5 things at the same time. We own a number of mobile devices from different manufactures, we have Android devices, Apple devices, Samsung devices. Google (starting with Jelly Bean 4.21) figured out the Apple protocol and starting with that release is able to draw the optimal charge on ports designed for Apple. My Nexus devices work well on different ports for most chargers, but the same is not true for my Apple devices and my older Samsung Tablet.

And now we see that some of the better chargers are beginning to add intelligent technology to the chargers so can figure out the optimal protocol to use for each device on any port. This GMYLE wall charger is one of this new breed.

I tested this wall charger using a current monitor with my Android phone and iPad Mini. I ran my tests with each devices on every port while it was the only one charging, as well while the charger was charging three tablets and two phones. The charger provided optimal charging on every port on every test. Impressive! I am including details below for those who like to see the technical details.
