Galaxy S7 Battery Case, Alpatronix BX420 4500mAh Slim External Protective Rechargeable Portable Charging Case Charger Cover for Samsung Galaxy S7 Juice Bank Power Pack [Android OS 8.0+ (Oreo)] - Black

I'm very pleased with this product, and am happy I purchased it. It more than doubles the battery life on my phone.The case itself is thick, but not overly imposing. It's about the same as a highly protective case from otterbox. It went on pretty easy but took me several days to figure out how to take off. Once I got the hang of it, it became quite easy and I take it off frequently when I am not working and have no need for longer battery life. On the bottom right there is a little protruding edge to assist in the removal. The trick is just to focus on removing the edges of the case, and once gone the phone slides right out of the battery back. It's really simple.You charge the case while your phone is in it. I have also just charged the case without my phone in it and that works as well. It will charge your phone and once full the battery case begin to charge. You are able to tell by 4 understated lights on the bottom back of the case. When you need to start using the extra battery, you just push a hidden button right beside the lights and your phone will begin to charge which you will be able to see by the usual indicators. I turn the battery off once my phone is fully charged and have enough juice left to partially charge it once more.I really recommend it!

I had a case exactly like this one but it was a different brand. It lasted about two years before the battery finally quit. I work construction and I have been rough on it. It's been dropped numerous times and took quiet the beating. The phone never took damage. In fact when I did take my phone out of the case it looked brand new. The matte finish really helps with grip. My Wife has the same phone and she said she didn't like the weight. It does roughly double the weight of your 8 ounce phone so if you have delicate wrists you may want to keep that in mind. I like the weight of it. It actually helps me from dropping it. The battery is plenty enough for a full charge and then a little bit more. The case lets the phone charge first then it'll charge. Your charging port in the phone will stay tight and solid so that right there will save phone life in the long run. It does get warm when it's charging from the case. That's normal. batteries emit heat when charging. I let mine charge in the work truck during the day a lot of times. Be sure to keep it out of the sun. They can overheat and that's not good for your phone or case. This case came with a charging cord (cord not charger) and the adapter you would need for a 3.5 mm jack. That saves you a few bucks right there. I bought a three pack off Amazon before to connect to my camper stereo. Some headphones are small enough to fit through the case but honestly your phone has bluetooth, just use that. This one also came with a screen protector. Another bonus. I already have one but if you don't you save like 4 bucks. It has a one year warranty but if it's like my last one, you won't need it. You won't be able to use wireless charging while the case is on it. So you're going to have to just unplug the pad and plug it into your phone. Not that big of an issue. You won't regret this purchase. Everything else on your phone will work fine.

I love this case so much better than my old Mophie! I had one for my iPhone & android & thought IT was Best product ever! So wrong I was. The price is the first reason, the weight & the plastic frame that goes around the front breaks & couldn't charge phone w that case on . I didn't realize that there were so many others out there that , in my opinion, were so much better.I love Amazon for variety, reading reviews & price comparison ability. I had you & 2 others I was trying to decide about. I chose yours for the weight, the phone charging automatically would charge the phone first, & then charge the charger. The fact that the charger is turned off until you need it & you manually push the button, it doesn't just just start as soon as your phone is low.For me, it keeps me aware that we are on the reserve power now, so remember to charge both up when you get home.Its thinner & had a nice design that helps me with the grip.I only had problems w screen protector. I need to get new one. Too many bubbles, then when trying to fix it, had become un sticky w fingerprints all over it.Other than that, I would definitely recommend it to a friend.

Just got this so I'm giving it 5 stars based on the concept since we've had these type before. Battery life is sufficient to recharge a Samsung Galaxy S7 and an S8. Durability, it solidly built so I'm assuming that it will be durable. Easy to hold, it fits snugly around the phone so, yes, easy to hold. If this make/model doesn't hold up to our experience with others, I'll update the rating.

Very ImpressedFor a company I’d never heard of I was hesitant to believe I was going to get more than an “average” mofi-style phone case.–After receiving my case, and a successful 2-weeks of use, I can report I'm pleasantly surprised. The company includes intuitive cards included in the box to remind the user to register their product/apply a rebate/and leave customer feedback, which I found helpful; there is an included microphone extension that I was unaware of when purchasing, but comes in handy for long car trips; and, the build and features of the case are at least “above-average”, and has consistently taken my phone from ~20% charges to a 100%-which was MUCH better than my previous case.All-in-all I think this is a 5/5 for the craftsmanship and “extras” the company throws in.
