EasyAcc 4A Dual powered my Raspberry Pi including HDD

In order to operate my Raspberry Pi incl USB disk as a media server, I was looking for a power supply, which has enough power to operate not the Pi, but also an attached 2.5 "USB disk.
Because of a USB port of Pis not enough juice came out to operate the hard drive I've bought a Y-cable and then try to use 2 USB ports of Pis - but that was not enough to operate the hard drive.
So I have a dual USB charger wanted and remained at that very depend on EasyAcc, a company that surprised me and convinces already with your Bluetooth According Pecher "EasyAcc mini".
And here I was not let down: the Pi the 1A port connected, one half of the Y cable into the 2.4A port and the other half in the Pi USB port -> finished the media server is the only needs a power outlet.
Test, I've also a cell phone (Moto G LTE) and a tray (LG Tab 8.3) can be recharged at the Dual Charger and since both devices were fully recharged within a few hours.
For me, again the evidence: Quality costs, but need not be expensive - EasyAcc appears with its products to combine both and my needs were satisfied with this product completely.
