PowerBear iPhone 5S / iPhone 5C / iPhone 5 [Stamina Series] Extended Rechargeable Battery Case with Built in USB PowerBank with 4200mah Capacity (Up to 250% Extra Battery) - Green [24 Month Warranty and Screen Protector Included]

Works for a little bit! Now don't get me wrong, it will always charge your phone but it will mess up your phones battery! I used it for about 2 weeks straight every time my phone would die I would turn the case on to charge it if I was too busy to use my wall charger. So eventually I start to notice that my phone would say that it's on 1% so I would turn on the case the soon as it turns on and the phone indicates that it's charging it jumps from 1% to 25%-35% instantly. Then when you take it off charge it will go from there to 10%! It messed my battery up! It does that all the time now. If I charge it up all the way and let it die all the way I won't have a problem. But who does that? Who lets their phone die ALL THE WAY? No one lol! I just use my wall charger now even though the damage is done. I don't need anymore problems!

First, the battery pack charges before your phone does. I don't like that. When you turn the battery on to charge your phone, it stays on no time before it randomly turns off. And the case is huge. Used a mophie before and it worked great but lost charging capabilities after a year but I used it every day, a lot. Can't wait for my new mophie to get here. This was a complete waste of my money.

This product is amazing. It allows me to charge my phone 2-3 times when the case has been fully charged. I recommend this to anyone who is always on the go.

It worked for a while, but it dropped onto the carpeted floor in my bedroom and now I'm not able to plug it into the charger! It didn't even fall that hard! So, apparently it wasn't very well made.

Love this product! It's a little big and bulky but works great!

Son loves it and uses without complaint

So far so good! Like the backup battery! Was delivered w/in 2 days - arrived by US Mail on a Sunday!

I returned this and you still charged me for it...terrible
