Works well just don’t like that full charge the phone then it charges the pack. Catch myself with times I don’t have a full charge

My job requires me to be on the streets for long hours, and this case has saved the day for me. It doesn’t charge your phone to full capacity or rapidly, but it does provide you with a backup battery that prevents your phone from dying.

It works well no problems i’ve had them in the past and they worked really well. I’ve tried other ones but they no good end. I’m not working so it’s good to be back with the mophie

Quality stuff nice case with makes the phone work really well

Great emergency charging back up when you don’t have access to a standard power source. Sometimes these do start to not effectively charge as they do when new: but thankfully they have a lifetime warranty

Great phone case charger holds up nice easy to take on and off maximum protection

Fits well In pocket. And charges my phone fast. I like the matte finish color.

Easy and protective cover that gives me extra confidence

Great charges fast. I got it for 79.99 great case and good quality..

This is the best iPhone battery case available. It offers great quality, so you'll never have to worry about a low battery again.

I live on the road. Airports, rental cars, client sites, delays, reroutes, and days that start at 5 AM and somehow end at midnight. My iPhone 17 Pro Max isn’t a nice-to-have…it’s mission-critical. Calls, email, Teams, boarding passes, car apps, hotel keys, two-factor auth…if my phone dies my day’s over. That’s precisely why the Mophie Juice Pack earns a permanent spot on my phone. This isn’t pretending to be something it’s not. It’s a full-on battery case that features an integrated 3,600 mAh rechargeable battery that can boost your phone’s life by up to about 50%. In real life, this means that I can land after a cross-country flight, hit meetings, take calls, and still have battery left without the trouble of “finding an outlet” in every terminal. The most attractive thing is how simple it is. There’s no separate power bank to remember, no cable to dig out of a bag. The Juice Pack is always there, always ready. If the phone battery runs low, a quick press of the button kicks in supplemental power. Simple. Effective. Just how it’s supposed to be when you’re moving fast. Protection is another one of many underrated wins here. The case does add real drop protection and isn't anything close to a rugged brick. It’s definitely thicker than a minimalist case (physics still applies here) but the bulk adds it with purpose, not sloppiness. I would rather have just a bit more thickness than a cracked screen and dead battery at 30,000 feet. Charging behavior is smart as well. The phone charges first, then the case when you plug it in. That’s huge when you’ve got 5 minutes at an airport outlet and need usable battery right now, not later. LED indicators clearly indicate remaining charge so you’re never guessing. There are trade-offs. With the case on, you won’t get wireless charging passthrough, and yes, it adds weight. It can even heat up when you’re charging hard and multitasking. None of that surprised me…and none of it outweighs the benefit of reliable, all-day power. Bottom line: whether you’re a road warrior, frequent flyer, or anyone who cannot afford a dead phone, the Mophie Juice Pack for iPhone 17 Pro Max is the answer. It’s not flashy. It’s not ultra-thin. It just works…and when you travel as much as I do, that’s precisely what matters.

Works good but your phone also loses power when the case is on because it’s always plugged into the case the phone thinks it’s charging the case

excellent charging case. protects your phone good and is not bulky.

I’ve been using the Mophie Juice Pack on my iPhone 17 Pro Max for a couple of weeks now, and it’s a solid option if you need extra battery life and better protection. The case isn’t too bulky considering it has a built-in 3600mAh battery—it adds some weight and thickness, but the phone still fits comfortably in my pocket. The build quality is good, with raised edges to protect the screen and camera, and it offers up to 6-foot drop protection. On the battery side, it reliably adds about 50% more life on heavy-use days (streaming, photos, navigation). There’s a manual button to start charging the phone, which prevents unnecessary drain, and priority charging means the iPhone tops up first when plugged in. It also has full access to the Camera Control button, which is nice. A few drawbacks: It’s $100, and there’s no wireless charging for the case itself (wired USB-C only). It does support MagSafe for accessories like wallets or mounts, though. If your iPhone 17 Pro Max battery isn’t quite lasting through your day, this is a reliable way to extend it while adding decent protection. I’d rate it 8/10—practical and well-made, but not for anyone prioritizing a slim profile.

It’s exceeded every expectation. It was greatly needed. I would definitely recommend this product to everyone.

The best invention for a smart phone ever… Mr. Patterson approved

Very useful and it’s a great product I would recommend this to everyone

Product is exceptional. Durable, everything I wanted in a battery case.

I like that i have extra battery charge available. Realistically will charge your phone 50%

The Mophie - Juice Pack Apple iPhone 17 Pro Max - Black is the iPhone companion you need for those power users that require more battery life than your new iPhone Pro Max can deliver is one day. From streaming to photo sessions, Video calls to social media, the Mophie is your backup power on the go without cords or needs to be attached to a wall outlet! Delivering on the go power boost to keep your phone charged and running beyond all-day use. I found this product to be very useful when I was out in nature doing photography where the cell signal is questionable at best and the battery drain was extensive.I was able to snap my phone into this case-charger and did not worry about losing power for hours. It is a bit heavier than I prefer, but the trade off is critical when battery power is required and phone shut down is not acceptable! PROS - Solid build, protects phone while charging - Easy slide off top to slide phone in yet remains secure - Depending on use, can charge phone from minimal to full 2-3 times - Fast recharge via USB-c or wireless charging CONS - Heavy!
