Verified Purchase(What is this?)
This review is from: PowerGen Black Mobile Battery Pack / External Battery Pack 3200mAh UltraSlim Power Bank Charger (with imbedded Micro USB) for HTC, Samsung, LG Android Cell Phones and iPhone 5, 4, 4s, iPod Touch and more (Electronics)
I got this to have as backup power for my Galaxy Ace and mp4 player for the daily commute to and from college. I've only had it a week but it has become as important to me as my phone! I don't leave the house without it, having it means I can use my phone for videos and games as much as I want without worrying about draining the battery.
I'll be using this intensively so I'm sure I'll wear it down eventually, but as it stands I'm getting two full charges for my phone and one full charge for my mp4 player which is more than enough for what I need. Even if I do overwork it and the performance decreases significantly I have no problem buying another one in a year at this price. Much cheaper than replacing my phone battery or entire mp4 player!
