What do I need to know to buy a portable charger for my iPhone 5S? Thanks!

I'm going on vacation so I want to have a portable battery bank. I've found several choices for a portable charger for my iPhone 5S. The Voltage by Urban Beatz with 2200 mAh , iHome with 2200 mAh, and Samsonite with 4400 mAh. Would any of these be too powerful? Thanks!

voltage is measured in volts anything higher then 5volt which is std usb volt will damage devices


mAh is mili ampere hours

ampere is current and that is not pushed but drawn there can be M(EGA)A(mpere)Y(ears) and it will not be too powerful because a device

which draw 1 milli ampere will do so even if the thing it's connected to can provide a Giga ampere
