Yes, you can use your Micro USB charger that came with your S4 Mini to charge this battery pack.

the led are flashing red
I have charged the pack up a few times now but this evening it has started flashing red when i plug it in to recharge it. I have tried a couple of chargers as well as plugging it in to my laptop but all result in the same thing. I'm sure this is not normal but don't know what i do about it.
The portable battery charging pack needs an electrical supply to operate.

Where to download online manual for eeb-ei1cwe
there is no online user manual for eeb-ei1cwe in global site and uk site. In order to understand led indicators, charging procedure and safety guidelines I need user manual (which I lost after purchase). Could you please send download link for this product. Thanks
It works because the output voltage (5.2V) is higher than the battery voltage (~5v). the power is provided by a inside battery and the usb ports are feedbacks-protected (energy can only go out,not in (protects the inside battery)
