iAlegant S6 Edge Battery Case, 4200 Mah Backup External Battery Charger Case For Samsung Galaxy S6 Edge Rechargeable Power Bank Case with Kickstand (black)

I love this thing!!! It is a bit bulky to keep on my phone all the time, but I just keep it in my school bag in case. It adds little to no weight to it. And when I am at school all day away from a charger, and my phone starts dying, I just pop this thing one. When you run your phone with lots of aps and stuff while charging with this it can get how, but it hasn't really effected anything yet. It charges pretty quick's, and snaps on easy. I've also use it to charge other phones that aren't the edge like my wife's S6, and it charged it fine even if it wasn't a perfect fit. Warning though, it is impossible to get the kick stand out. Still worth 5 stars though.

It's a good battery case, It's REALLY heavy though so make sure to wear a belt if you want to put it in your pocket

Great case. It makes my phone last for a whole day and charges fast. In many ways it works as expected. The only downside is that the button, that starts the charging is easy to be pressed when in the pocket accidentally.

The case looks and feels really good i have been using it for a while and any problem with it

I love that my husband's phone is able to last all day. He has been able to take pictures with his phone on his trip without it dying every hour. He is so thrilled with his battery case.

Was ok for short immediate charging.

It works great!

I've only had this for a few days, so I will update if anything changes. So far it does exactly what I want, recharge my phone when I'm not around an outlet. Great for when I have to travel. It will make your phone more heavy and bulky, as to be expected. Haven't decided if I'm going to start taking it off when I don't need it, but I might, just so that it's not so bulky all the time.
