Nice product, but to use it properly

Warning however: This jack is equipped with 2 USB ports at 2 different amps.
This is a good idea to base, especially for those with mixed devices (Apple + Android).
However, this amounts to only have one port if you have a single (Apple or Android, for example).
Indeed, it is important not to connect a device to an outlet too "strong" for charging.
Load too quickly reduces battery life.
So if you have only Iphones for example, this outlet is larger than the one delivered with final.

Also, I recommend the use indicated on the device ie 2.4A for "Apple". This is too much for Iphone that come with a charger 1A. So use the one labeled "Android". This can be misleading ...
Personally I therefore uses that indicated "Android" for my Iphone ...

Thus, the product itself is well done, nice and very useful for those who know exactly that it needs to plug different amps.
For others, the risk of inappropriate use. Hence the star less.
