Can you use a USB docking station to charge multiple devices efficiently?

Added (1). I want to make my Targus docking station a multi-USB port charger. It runs at 5V and 2.6A with 4 USB slots. Will it be an effective charger to 4 devices? The docking station will be plugged into a wall socket with an iPhone wall plug.

No. Most phones need 1A to charge, some take more (mine pulls 1.8A to fast charge). Only providing.65A to each device will take the phones hours to charge, if they even charge at all.

There are docking stations that are higher amperes to be able to charge multiple devices, but your station is not one of them.
