iPhone 7 Plus / 8 Plus Battery Case, XchuangX 4000mAh Rechargeable Protective Charging Case Slim for Apple iPhone 7/8 Plus (5.5 inch), Support All Types Headphones, Answer Call, Sync-Through-Black

I really wanted to like this product. I've been looking for a decent priced charging case (under 50$), that also wasn't bulky, had good charging power, and had sync capability so that I didn't have to keep removing it when connecting to my car to play music. This case seemed to hit all the marks. It is a decent price, VERY slim and light, seems to charge the phone very well and indeed connects to my car when plugged in. However, the issue is that it doesn't securely hold on to the top of my phone very well. When in my pocket, the phone is often half way coming out of case at the top. I am most likely returning the case in hopes of finding something that fits a bit better. All other reviews seem positive, so it may be that I just got a faulty item.

​I honestly like this case! It's super slim for a battery case and provides sufficient protection thanks to its soft silicone exterior. The simplistic design makes all the ports easily accessible, and buttons are effortless.However, as some reviewers have mentioned already, the silicone exterior made be great as a protector, it attracts a lot of lint. On top of that, the soft texture makes it especially tricky when putting the phone in your pocket.Sadly, I had to return mines. The figures don't add up. I purchased it for my iPhone 8 Plus which has a battery capacity of 2,675 mAh. This case has a capacity of 4,000 mAh, nearly 50% larger. Somehow it drained over 25% to recharge my phone from 92% to 100%. If you're a heavy user, this battery may not last throughout the day.

Update after using for two weeks:Power doesn’t last enough. The battery is thin and can’t store enough juice.The case is VERY HARD to remove.Case collects dust and grime very easily and is not easy or slick to fit into pant pockets.Easy to use and flexible. Not a rigid case. Flexible silicone. Although it generates the dreaded accessory not supported warning when I connect to iTunes

Slim, Nice Material, Good Battery Life, BUT CHARGING PORT BREAKS! I wanted to love this case, I really did. Looks amazing, so slim you can't even tell its a battery case. Feels great in the hand. It was perfect. Broke after 2 weeks. Exchanged for a new one (no issues with exchange), Broke after first week. Something is wrong with the charging port, after a while, it's a pain getting cable to make up contact with charging port. ALMOST PERFECT, but in the end.. had to just return it and get a different case altogether.

Great looking thin case, however the silicone is a bit on the slick side. The top tends to come off of the phone leaving the top of your phone exposed sometimes. The extra battery life is nice when you can get it to charge the phone. Sometimes it takes turning the charging function on and off a few times for it to work.

I was skeptical about this charger based on its low profile, but it's been great, especially at this price point. It got about 2 full charges for my phone, with heavy use. Perfect for a weekend trip!I don't traditionally like silicone cases but this one is great and on top of the charging aspect, feels like it offers more durability and protection to my phone.

I had to send it back. It installed nicely and had a good feel. When I turned it on it started to charge, but soon stopped. After 2 or 3 more tries it made it to 100%. I restarted the phone with the case attached and it stayed charging to 100% but then started flashing accessory not supported and wouldn't stop. I know it was cheap but I didn't expect all of these problems. Also had poor instructions and no support.

It is super easy to use and you just use your regular phone charger to charge it!! It takes a little while to fully charge but it is worth it. It helps me every time I am running around and don't have time to sit and charge my phone, I can just use the case to charge it on the go!
