    Nice Charging case with one issue for me...

    The mophie - Juice Pack for the Apple iPhone 17 Pro Max, for what it is, it has a nice clean look to it but it makes the phone noticeably larger and heavier. The covers over the buttons have a nice, positive action to them. The are not mushy. There is a solid click to let you know it was pushed. The case feels like a sort of soft plastic but it is still quite hard. It's hard to explain. Unfortunately, it is quite smooth and can, and has, slip out of my hand. The case has a nice, clean, integrated look to it (unlike the Apple add-on battery), but it takes some effort to install or remove. The fit is tight on my phone out of the box but will hopefully loosen up over time. The Apple battery is easier to install and remove since it is a MagSafe accessory but looks like a wort on the back. One down side is this will only work with iPhone 17 Pro Max. It might not work with your next phone unlike the Apple battery which will work with any MagSafe capable iPhone. There is a 4 LED battery strength meter on the back. As well as a small button to check charge level or start charging The case will attach to a MagSafe accessory (charger, phone holder, wallet, etc) but it will not charge via MagSafe. Charging is thru a USC C cable only. I'm sure this was done to save weight and keep the case as compact as possible. However, the case is already adding noticeable weight and bulk so I think I would prefer having the option to charge wirelessly. When charging thru the cases USB port, it prioritizes charging the phone before charging the case battery. The mophie battery charges quickly. Under 2 hours from 2 LED Lights to Full. Around 3 1/2 hours from 0% to 100%. It kept my phone charged at 80% for a full day (a light use day) and still had 25% left. A lot of video watching would reduce that time. At one point I discharged my phone down to 19% and installed a fully charged battery pack. It took 1 hour and 15 minute to discharge completely and my phone went from 19% to 64%. So this pack provides about 45% extra battery to the phone. Conclusion - For those that need a battery like this and want a clean integrated look, this Juice Pack is a no brainer. It looks great and provides a noticeable boost in run time. It takes a minute or two to put on and take off compared to other solutions but it looks a lot better. My only big issue with it is that I can't charge it wirelessly. If it could do that, it would be almost perfect. If you can deal with that, I say go for it.

    Charged my phone for all day use

    I’ve never had one of these cases/chargers before so this is my first experience. I have also decided to go from a pro to a pro max so the size difference by comparison is a huge difference to me since I have small to regular size hands for a female that’s 57. So being able to comfortably grip the phone with one hand is no longer an option. So I figured if I’m going to be using two hands to use my phone I may as well upgrade the case and because I use my phone a lot on social media not having to charge it as much as a huge convenience. Insulation was super easy you just slide open the case slide the phone and slide close and press the small button on the back bottom of the case to start charging the phone I have a phone charger in my car, but not sure if it works because it goes on and off when charging. But all the other charging cords work perfectly fine and the lights flash on the back when it’s a successful charge. It is super heavy, but I have dropped my phone and I feel like the heaviness of the case protecting my phone I’m a fan.

    Premium Feel and slim designed battery pack

    Unboxing, I was impressed by the overall quality and weight compared to other battery packs I’ve tried. It feels solid and premium, smooth in the hand, and well balanced. Most importantly, it didn’t add noticeable bulk to my phone — just a little extra weight, and still much lighter and more convenient than carrying a separate power bank. The smooth finish feels nice but is slightly slippery and shows fingerprints easily, so it can look smudged unless wiped down. Installation was very easy, and charging the case itself was straightforward. After the initial charge, I installed my phone when it was around 10%. At first, I wasn’t sure how to activate charging because a quick press of the button only showed the four indicator lights blinking. After a little trial and error, I realized you need to press and hold the button longer to start charging the phone. As soon as it was turned on, it worked very well. My phone charged from about 10% to 80% (my set limit to protect battery health) in just under an hour. I really like that this is a battery pack that also serves as a protective case that you can turn on and off — I can stop charging once it reaches 100% and then turn it back on later when I need more power. Overall, it’s a nice phone charger that does not add extra bulk, just a bit more weight, and still feels lighter and easier than carrying a power bank. I recommend it if you’re looking for a slim, integrated battery charger that you can turn on and off as needed throughout the day. The reason for the four stars is because the case shows all fingerprints and a little slippery. Would be nice if you had a little more grip.

    Protective Battery! Qi charging?

    TLDR: Protective battery with no Qi I really enjoyed the product. The material is rubbery, I felt it was durable. Dropped the case by itself a few times just to see how it would fit, and it felt fine. So I put it on my phone, a low drop, no problem, all the cameras, buttons, etc are well protected. The fit is very neat/tight. Easy to put on an take off, which is nice. The way the case charges is through the usb c, so there is a port sticking out on the bottom of the case, you plug that into your phone, then slide your phone on. It is NOT a Qi battery, so it's not charging via the back of the phone. Which I suppose is nice, as the battery charges faster, at least it feels that way. Qi 7.5 / 15w, as opposed to the ports ability to go beyond that. I do wish however it had Qi charge on the case itself. The way to charge the case is a USB C port on the bottom of the case. I wish it had both, it would've been nice. I took a star away from it, as I felt this should be most cases in this range in 2026. Otherwise it performs as advertised, a protective case with a battery. It constantly just keeps your phone up, I recommend turning on your phones battery protective feature, to keep it at 80% to preserve your phone. Otherwise no complaints.
