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

posted by dunkiper on 03/15/2013 Certified Owner

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
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.
Cons:
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.
Other:
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.
Bottomline:
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.
