I have purchased at least 3 different phone cases included 2 that could charge my phone. I was about to give up when I read a review from a customer about this product. He/she did not exaggerate. This is by far the best storage/battery charger that I have seen so far. Moreover, it is sleek, beautiful and very high quality material. I highly recommend this product!

Extended the life of my battery by 3 fold! Fits snug around my Samsung Galaxy S3. Leather flip cover (a bonus) is nice a sturdy. Protection a plus. The flip out stand is a little worrysome (if I use it at all). With just the push of the power button on the charger, you can charge your phone in about 1 hr.

Took me a while to figure it out (longer yet to remove phone from my Otter Defender). Great back up/extended power and quality look for Samsung Galaxy3.

I love this case,it has great style & looks nice & also great backup battery power to charge my phone,The only dislike I have is the front cover flap doesn't stay closed,I wish it would of been magnetic or have some kind of closing device to keep it closed... But I still recommend it highly.

The main reason I bought this is for the extra time without charging my phone constantly. Although I've only had it a short while I live the battery life. Another good thing is the fact u can charge the case, without having the phone in it, and it looks great.

I purchased this case a month or so ago and am really in love with it. So far I have actually had 3 of my friends and 2 of my family members purchase this exact same case with Outedge after they seen mine. Highly recommend. I promise you will not be disappointed.

This case has a really nice eye catching design and is very powerful. For the price, I would not pass this thing up. I am buying one for my wife today...

I previously had purchased the mophie Galaxy S3 battery case but it finally stopped working after months of use. Instead of purchasing another one, I decided to shop around to see what else is out there. I came across this battery case and found it had a much stronger battery and a much lower price. I decided to purchase and am glad I did. This case definitely has a nicer design and is way more powerful. I feel like this case actually protects my phone more than the mophie one did. If your looking for the best battery case around for Galaxy S3 look no further!
