A simple "battery pack"  isn't 5 volts it depends on the battery it uses use however there are a number of things called USB "power banks" or "portable chargers " which are basically a 3.6V rechargeable battery in a box with a charger and a 5v generator built into the same box.  you can charge them from a USB port and then plug in a USB device to charge that device.  some however are "clever" if you don't take enough current from them they think the plugged in device is "charged" and then shut down.
