    I got battery cases for all the iPhones since the 3GS from every brands and this one is by far the best of them all.

    It feels a lot better than mophie in the hand and the power button does not get pressed by accident in my jeans pocket.

    Also good to have a manufacturer doing a battery case in white, it looks like Apple designed this case with perfect finish and color match.

    Just got mine in white this morning, very pleased with it. A lot more comfortable to hold than mophie, perfect fit and look very good with a white iPhone unlike every other black cases. The SD card expansion and availability of white model make this case the best iPhone battery case ever.

    I bought I Phone 7 and 7+ black plus battery case, the design and idea are excellent. Just come areas that need to improve, such as during phone charging if it could bypass the battery case that will be nice to have. Furthermore, if bigger battery capacity that will great too. Thanks

    Very good case and expansion system overall. The microsd card expansion is a wonderful feature– have a 200 GB card and now have more than double the phone capacity for files. The hardware all works fine once you know how to operate it. The iOS app (SmartCase app) which integrates the memory expansion card to the native iOS system needs a little more polish, but overall works well. One important thing that the documentation doesn’t tell you that you need to know is that occasionally you will need to reboot the battery case so that the charger and expansion card functions properly. To do that you hold the case’s power button down for 20 seconds, and then it will reboot and everything will work. The only other suggestion I would have is someday to increase the battery capacity. I’ve noticed that the battery charger does get drained pretty quickly when charging and using the memory expansion at the same time.

    I was very surprised by the quality of this case. Great feel in the hand with great features. At this price I’m referring this product to everyone who has an iPhone 7.

    I love this case I brought another before this but sent it back because this case was so good, the only downfall is that u have to take the iPhone out everyone u want headphones in but it doesn’t bug me that much to want another

    This is a great case. It feels great in your hand and is very high quality. It is also much cheeper than the Apple rechargeable case.

    Чехлы понравились.
    Купил чёрный 7+ и белый на 7.
    Заряжают исправно. Работу sd пока не проверял.
    К варианту на 7 вопросов нет. Все сделано очень аккуратно.

    А вот на 7+ немного озадачил. Ширины боковых стенок не хватает для того, чтобы телефон можно было положить лицевой стороной, только если на стекло. Не хватает каких то десятых долей мм. Это странно, так как с вариантом на 7 такого неудобства нет.

    Здесь же отмечу, что гибкая верхняя часть чехла для обеих моделей сделана без учёта её отгибания. В результате в собранном виде верх немного надломан в сторону от экрана. На эксплуатацию не влияет, но на фоне общей продуманности устройства, слегка удивляет.
    Было бы удобно иметь в инструкции более подробное описание режимов работы с аккумулятором. Вот почему он сам перестал заряжать 7+ после того, как заряд дошёл до 80%?
    После повторного включения аккумулятора все зарядилось нормально, но можно же об этом написать пару строк в инструкции?
    И по обозначениям индикаторов так же хотелось бы больше информации в инструкции.
    Это же чехол с аккумулятором, а не ребус?:)

    В любом случае, оба варианта рекомендовал бы к покупке.
    Отличный вариант дополнительной зарядки по хорошей цене. Да ещё и с sd!
    К тому же легкие, компактные, красивые и приятные на ощупь.

    Ce case est vraiment bien. Bonne prise en main, ne rajoute pas de poids réel a l’appareil. L’idée de la carte micro sd est tout simplement génial. Bon prix pour tout ses avantages. Je le recommande!

    I use iphone 6 plus but use iphone 7 plus casing. All ok just the camera is somewhat shielded by the casing. But can diy a bit. For the earphone also need a little diy for the better. Smart app still support iphone 6 but can not read the app kuke. Sorry admin …. for trying things out of the mood. I just want to know.
    So far, this casing is still best in my view as it is a quality product. keep it up kunercase.com
    Just want to request for the next product data can transfer to kunercase over 1.5gb or more.


    • Hi Emanz
      Thank you for the review.
      The two phones have different camera position and so the case will cover the iPhone 6 camera. Glad to know you are able to use an iPhone 7 plus battery case on an iPhone 6 plus. But this is not recommended for other users. You need to cut the case.
      The case can transfer single file of size 3.5gb. Please try to format the SD card with your case. Or try another SD card.

    Excellent case. The first one I received had a factory defect and they gladly sent me another one as a replacement. It has all the features I’m looking for a case (memory expansion, extra battery life) and it still protects my phone from everyday use. Definitely recommending this to anyone looking for a battery case for their iPhones.

    It takes a while to get this case to Europe but its worth it. I have used the products of Mophie for a long time and it’s a super nice product. I saw this case came by on the internet and saw some reviews, i have to say u can go wrong for this price the battery case is super slim and u have the option for and extra 256 gig’s of storage may u need it. I would recommend this case over the Mophie case if we look on how slim the Kuner case is the only thing that i miss alot in this case is wireless charging. But with the new iphones that came out this is not an issue anymore

    It is a good battery case, but it doesn’t recognize the SD card. I don’t know if this is a problem with the case or the app. The app looks nothing like the description in the info. It doesn’t recognize the case when plugged in to the computer, so I can’t use it as an extra drive either. The storage is completely useless.

    • Sorry to read about this. Please format the SD card using our APP. We use smartcase APP for the iPhone 7 memory case. Please contact customer support if you still have problems using our case.

    The Kuner Case feels great in the hand. I was worried it would be a waste of the iphone’s aesthetics to use a case, but it really still looks and feels great. It’s surprisingly slim and the soft shell seems study enough.

    The lightning port works correctly with headphones with little problem after an initial set up using the instructions.

    The battery in the case charges well, and the phone can be charged directly with the case on. Using the case charge to charge the phone though.. works, but seems slow and x% of the case doesn’t seem to equal x% going into the phone.

    The memory works, but SD cards don’t really lock in, so it has to be laid in perfectly. Originally it gave me a message my SD card was now broken (scratched), but after some fidgeting it connected again. I don’t feel confident to store essential things, but I’m happy to use it for movies/tv show storage and contact back ups, which is what I wanted anyways.

    Overall I would definitely recommend this case to friends and family. The cost is worth it and its unique features set it apart from all other cases. IT was also worth the wait in delivery time.

    • You really need to use your fingernail to push it up until you hear a clicking sound, at which point the card will lock into place. To get the card out of the slot, push it down using your fingernail. Please contact customer support if you still have problem with the card slot.

    I really love this case. I love having a case that protects my phone, has a battery to recharge my phone and a slot to install a micro sd memory card for more storage. There a few things I would like to see updated for future case. 1. A larger battery to be able to get more than one charge. I know it’s possible because other cases that have batteries in them can charge the phone up to three times off a single charge. 2. I would like a software update of the firmware in the case to allow more than 256gb micro sd card. I know 256gb already sounds like a lot but when you are on a long trip you may fill 256gb fast with pictures and videos and I don’t want to carry more card around and potentially loose them. 3. The top rubber piece that holds the phone in is not as snug as I would like. The phone is in tight and has no possibility of falling out because the other three side hold the phone in great. It’s more of a slight anoyance issue 4. This last one is not a deal breaker but it would be nice to have the capability to have wireless charging built in. It’s not an necessarily feature but would be nice. Other manufacturers have them built into their cases that have batteries in the case.

    Love the case for exactly what it is, an extra 50-100% battery life and the memory expansion. As stated before I too wish the top rubber was a little more stable, a screen protector or even an otter box style protector case with the capabilities of the kuner would be the only way to improve.

    • Thanks very much for your purchase. The top rubber piece was made to removing the phone easily from the case. It is not as stable as other sides. We will try to improve it and find a compromise.

    Great case so far but I had another great case that only lasted about six months. Let’s see how long this one last. I will give a more detail review in about six months.

    I’ve had the 7/8 case for about a month now. Physically the case is very nice. iPhone fits snug in the casing and it feels like a natural extension of the case. The anti-slip material is a nice bonus and it doesnt add much to the phone, either in weight or size.

    The one area that needs work though is the software. I bought this case mainly for the extra storage specifically music. To play music you have to use the SmartCase software, which works, but is a little lacking in functionality. For instance, whenever I start a song after switching on the case, it plays for a few seconds and then skips to the next one. Minor annoyance. It also doesnt have an EQ setting. Aside from that importing photos/videos etc from the phone are all a simple click but I have had issues with timeouts where the software reports there is no SD card. Switch off the case, back on, restart synch and it works again. All small issues that can be fixed with software updates

    All in all I would say the pricing is good even if you just use the extra battery. Having the extra storage space via SD card should be viewed (for now) as an added bonus.
