I am looking at getting a 3 port USB wall charger, to save having so many individual ones plugged in. A lot that I've seen offer Qualcomm FastCharge, and other similar things, which are around 2.4A, or higher.
The chargers that I currently have (which are cheap ones) are alll 1A or less (with the exception of my Lenovo tablet charger, which is 2A). I'm slightly concerned that using such a charger will overload my devices (eg phone), and cause damage to the battery. I have a fairly large powerpack, I think 10Ah, and it says that it should be charged with a 1A current.
Am I right to be concerned?
