I was really skeptical on this battery charging case I thought to myself what can be so different from other charging cases? To my surprise!! When the package arrived I immediately opened and began using the case. I noticed that this case was not as restrictive as other cases. For example the charging port is right where you’d expect it to be. Since my time of first use I have gotten used to not charging my iPhone 7 as often as I did without the case. It is great for various applications. I am a mechanic and mobile detailer and often when I’m working on cars I listen to music. This charging case has allowed me to extend my charging by cable intervals to only one time a day and that is mostly at night when I end up plugging my phone. That is amazing what this case can do. I love the fact that I can go anywhere and not worry about carrying a charging cable or extra power bank because this is enough to charge your phone for the whole day. I would really recommend this if you have an iPhone that the battery does not last as long and you do not want to buy a new phone just yet. Very great product. ### ⭐⭐⭐⭐⭐ Great case for any iPhone 6 to 8 *by C***E on December 27, 2018*  I've used this case for about 2 weeks now and suffice to say it has changed my life. I've always found that the battery life on the iPhone 6s is poor and will run out by about mid day - this case is perfect for extending the phone charge for the entire day.The case will hold about 2 full charges when fully charged, enough to last for a full day (and night) out. It is not bulky like some other battery cases. It fits snug to the phone and is very sleek. The buttons on the sides work well and the speaker and headphone jack are completely accessible. For a long battery extender, it does not add too much weight to the phone either. While it is certainly not an OtterBox, the case does provide some protection (I've dropped it on a hard carpeted floor and nothing has happened). This case also fits well with my girlfriend's iPhone 7 and sister's iPhone 8.I would highly recommend this case as a relatively cheap battery extender, for iPhone 6s users specifically, you will notice an immediate difference. ### ⭐⭐⭐⭐⭐ Got it for my mom's phone, mom loves it :). Fits on the iPhone 6s just fine! *by T***I on December 17, 2018* It fits just fine on the 6s even though it says 7/8 on the box. This was my biggest concern, but it has both the earphone port properly spaced as well as the camera. It looks like the camera doesn't have enough room off the top but it does. Pictures look great as well.I'd suggest reading the instructions since its actually legible and comes with pictures and etc, but you have to hold the button on the back for a couple seconds for it to start charging. After that you're solid. The chargers not even that thick, it's great on the hands as well. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/103032874-iphone-6-6s-7-8-battery-case-rechargeable-extended-battery](https://www.desertcart.pl/products/103032874-iphone-6-6s-7-8-battery-case-rechargeable-extended-battery) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-28*
