Useful in case of emergency – AA-Battery USB Emergency Backup Power and Charger Pack Reviews

Very useful in case of emergency when you don't have a nearly source of power. For example, in my case, when going outdoors to the mountain using my mobile device as a GPS and running out of battery. This tool saves me of being out of communications in an emergency.
It is not the same power as a real source of power. I use it with four rechargeable batteries and don't get the same results. Slow charging times and don't get full battery on my mobile device.
It's ok just in case of emergency. It does what is supposed to do: help you with a bit of charge and allow you to arrive to a safe place to charge your device.
It's worth to have one because of it's low price despite it's not perfect. But can help you and save your life in a situation when you need battery on your mobile device to make a call, for example.
