Hands down best battery case by value and size!

Slim battery cases for the larger iPhones, such as the iPhone Xs Max, are hard to find. This case not only offers substantial battery life, but it also fits perfectly in your hand, pocket, cup holder, or anywhere else you put it. This battery case has a major difference among the others because it does not make the bottom of your phone an extra centimeter longer as other battery cases do. It may not seem like a problem, but that extra length messes with hand placement when holding your phone. Another key takeaway from this case is that it can be charged with the normal Apple Lightning cable instead of some random MiniUSB or MicroUSB cable. I personally tried the Apple Lightning cable and a USB-C to Lightning cable and they both worked perfectly.

Great product!

I got this charging case before I left out of town, I knew I wasn't going to be near a place to charge my phone so I looked into a charging case that I can use while taking pictures and not have to worry about my phone dying hours later because of the full brightness in the sun. Right off the bat when I got this case, it was really light weight and I didn't feel like it was too heavy to hold. It was also nice because it wasn't a slippery texture and I have no problem with it falling out of my hands, it didn't add too much bulk, barely noticeable from my last case, so it felt like it already did! I think one of the things I like most about this case is the fact that I can use this as an actual case instead of using it as just a backup battery case. I do not have any cons about this product as I continue to use it. Overall, great product!

Will charge the phone case

So my iPhone Xs Max is on it's way and I am already prepared for when it gets here. I got a this case specifically since I had the same case for my iPhone 8. It is a protective case as much as a charging case, I am constantly on the road and sometimes have no where to charge my phone. please remember this case is not supporting car charger and I use my GPS constantly. Super excited to hit the road with my iPhone!

Quality product for a bargain of a price!

The charging case from Swaller is surprisingly one of the best phone cases I've used, along with the fact that it has a built-in lithium battery to keep your device juiced for the day! As a travelling professional, this feature is a life-saver, and it doesn't even come at the cost of a lot of bulkiness onto your iPhone. I can still use many of my external accessories while the case is still on due to its non-obtrusive design. The case itself gives me about one full extra charge on top of the on-board battery, which is excellent. Paired with the fact that I can charge the case and my phone each night at the same time, this device couldn't be better. I love it! It also supports pass-through, so if you connect your phone while its in the case to a laptop, for example, you can still transfer media to and from it as well! My only nitpick is that it can pickup fingerprints easily to the matte finish, but its a small thing while compared to the benefits of the design. The buttons dedicated to the volume and lock buttons work great, and are completely unobtrusive.

Great battery for the money and it works!

Great extended battery for IPhone XS Max! Easy to remove but there’s no need. Had a juice box extended battery but hated the micro USB charging! I love the lighting charging! Makes charging so easy and I leave home and never worry about looking for a charger!

Great Product

This product is amazing! Love how I’m able to obtain a grip of this product. I’m able to keep a charge all day without having to plug up my phone. As a developer, I’m on the phone majority of the day. Quite frankly, I enjoy just letting the phone go down to about 30% just so that I could hit a button on the back of the case. Also, it’s not bulky, so I’m able to put it in my pocket without a problem. I only have one con to the design of the case. My phone case shows the grease of my hands. I have to wipe it throughout the day to have it look clean. But all and all, it’s a great product! My initial reason for this product was for traveling purposes, but now, I can’t keep it off! It comes in handy and you’ll never regret it!
