Best Phone Battery Charger Cases of 2026

"After years of using different battery cases, I can confidently say the Mophie Juice Pack stands out for its superior design and function. I love how I can just leave it on and my phone uses the case battery first, really helping extend my phone's battery life. No more constantly switching things on and off. The case is slimmer than generics, feels premium, and fits my daily routine perfectly. Highly recommended if you’re on the fence."

"I’ve been searching for a MagSafe battery case and this one delivers a strong magnet and a solid grip. The USB-C cutout is spot-on and installation is a breeze. I just wish the lower part was a bit shorter, and unfortunately, customer service has been really slow with my warranty claim. Still, it’s a great case if you need strong magnets and easy charging."

"I've tried cheaper battery cases before, but they just don't last. This case powers my iPhone SE up to 60-70% and the build quality is far better than no-name brands. The USB-C pass-through charging works flawlessly, and the design balances slimness with battery capacity. Definitely worth the extra cost for the quality."

"I really appreciate how compact and lightweight this charger is—it fits perfectly in my small purse, making it incredibly easy to carry around while traveling. It’s been a reliable backup for my phone during trips abroad."

"I’m impressed with the magnetic attachable power bank; it’s so convenient and can recharge my phone multiple times before needing a recharge itself. I plan to buy a second one because it’s just that useful."

"This is the best power bank I’ve purchased so far. It charges my phone quickly as long as it’s not in my pocket, and the overall experience has been fantastic."

"I'm a frequent business traveler, and this charger is a game changer for me. I can easily go two days without needing to recharge, and I no longer have to hunt for outlets in airports. The case is a bit bigger than a normal phone case, but that’s a small price for the incredible battery life. I typically don’t leave reviews, but this product is truly exceptional."

"After buying a used iPhone 13 with only 85% battery health, I was frustrated with how quickly the battery drained. With this replacement, my phone now lasts all day with battery to spare. The fit is perfect and it's made a world of difference for my work needs."

"I wanted a case that would keep my phone powered throughout long days and trips, and this one delivers. Its slim, stylish design and lightweight feel make it easy to carry, while the 7000mAh capacity easily gets me through the day. The LED indicators are convenient, and the added screen protector gives extra peace of mind. It doesn't support wireless charging, but the extra battery life is worth it. I highly recommend this to anyone looking for style and performance in one package."

"I've never been one to leave reviews, but the Alpatronix Battery Case for my iPhone 17 Pro Max deserves praise. It has completely changed how I use my phone — the battery now lasts all day and then some, even with heavy use. The sleek design and premium feel are huge pluses, and I appreciate how charging both the phone and case together is effortless. If you want peace of mind and extra power, this case is absolutely worth it."

"As a repeat Alpatronix customer, I can say their latest battery case really impresses me. The USB-C port is a major convenience, and wireless charging works perfectly, which solves issues I had with older versions. The build quality is protective and solid, and the battery capacity gets me through even the busiest days. I also loved the included screen protector. If you want reliable power and protection, this case has it all."

"This battery case has become a true lifesaver during my travels and long days away from chargers. It's easy to use, attaches securely, and genuinely extends my phone's battery by over a day. Charging is straightforward, and the added screen protector is a nice bonus. I feel confident using Alpatronix products and would recommend them to anyone needing dependable extra power."

"As someone who's constantly on the move, I really appreciate how this case keeps my phone charged throughout the day. The 8500mAh battery holds a lot of power, and I don't have to worry about finding an outlet or carrying extra cables. It's not too heavy given the battery size, and the sturdy build offers great protection for my phone."

"I was surprised by the quality and practicality of this charging case. It eliminates the need for separate power banks, charges quickly without overheating, and even came with a bonus screen protector. The fit is perfect, and it helps me stay connected when I'm away from home for long hours."

"While the case does add some weight and doesn't support fast charging or data transfer through the port, it's still a solid choice for anyone needing extra battery life. The design is sleek, and it offers a noticeable boost when my phone's running low, especially at the end of a busy workday."

"I bought the mophie juice pack for my wife’s iPhone 15 Pro Max, and she’s been using it daily. The extra battery life is a lifesaver on busy days, and the drop protection is noticeably better than regular cases. She especially likes the sleek, slim design that doesn’t make her phone feel too bulky. The eco-friendly materials are a plus, and being able to use wireless charging is super convenient. The only minor downsides are that it adds a bit of weight and only comes in black, but for us, the benefits far outweigh these small issues."

"After having Mophie cases for my past iPhones, I was hesitant to get one for my new iPhone 15 because the previous version for my iPhone 11 wasn’t great. But the improvements in this new Mophie are outstanding—better durability, stronger corners, and a raised edge for protection. Charging is now much easier with one integrated plug. I’ve used the backup battery more in a couple months than with previous models over several years. Very happy with the quality and upgrades."

"In my experience, the mophie juice pack is probably the best battery case you can buy. It gives my phone about 50% extra charge, perfect for getting through the day. It’s smaller and lighter than other battery packs, and the comfortable fit makes it easy to use. It’s pricier, but the quality is worth it. I highly recommend it."

"I've tried several glass protectors, but this one is my absolute favorite. Installation was effortless, it feels just like the original screen, and it doesn't affect brightness or touch at all. After a couple of drops, my phone screen is still flawless—only the protector took a small chip, which is exactly what I want. The quality and value are unbeatable—I’d definitely buy it again."

"The TAURI case for my iPhone 17 Pro Max is by far one of the best protective cases I've owned. It’s solid and premium without any bulk, and the camera and screen protection give me real peace of mind. The anti-yellowing material keeps it looking fresh, and my phone has survived several drops perfectly. I highly recommend it for anyone seeking reliable, stylish protection."

"I’m really happy with the look, thickness, and clarity of this case and protector combo for my new iPhone 17 Pro. The only thing missing was a custom guide for easy installation—it would have made applying the screen protector much simpler. Other than that, it’s a quality product and I hope it stays clear over time."

"As someone who uses my phone heavily for work, travel, and entertainment, I really appreciate the extended battery life and dependable protection this case provides. The fit is excellent, and wireless charging works seamlessly with my charging setup. While it does add some bulk, that's a small price to pay for the convenience and reliability."

"I've been a loyal user of these battery cases for several phones, but recently I've had issues with the charging port breaking on multiple cases. Customer service was unresponsive and warranty support was not helpful. The product used to be great, but I'm disappointed in the current quality."

"After struggling with my iPhone battery draining quickly, I gave this case a try because of its strong reputation and excellent packaging. I've found it to be solid, easy to use, and reliably protective. Customer service is outstanding compared to other brands I've tried. If your phone battery can't keep up, this case is a great solution!"

"With this case’s huge 10,000mAh battery, I easily make it through the day, even when I’m using my phone a lot. The LED display keeps me updated on the battery level, and it’s awesome that I can use USB-C for both input and output—charging my earbuds or tablet straight from the case is super handy. I also love that it supports wireless charging both ways; just drop it on a pad and let it charge, no cables needed. Best of all, I can still use Android Auto, wired headphones, and transfer data without removing the case. It’s sturdy, has raised edges for protection, and isn’t as bulky as I expected for the battery size."

"I’ve been using this since the S25 Ultra came out and it’s held up really well. While it is a bit bulky, that’s typical for battery packs, and I’m impressed by how well it protects my phone from drops. Wireless charging works through the case if you get the positioning right, but I usually stick to the cord for convenience. The battery capacity is great for my work, where I’m constantly taking photos all day. The only minor gripe is that the button to activate the pack can be triggered a bit too easily, but it doesn’t ruin the experience."

"I’m a long-time fan of Newdery cases. This one is thick and heavy, which I actually like since I have big hands. It can charge my phone twice, making it perfect for travel. The fit is snug and secure, and I appreciate that it supports wireless charging too. The only thing I’d improve is adding smart charging to shut off automatically at 100%, but overall, I really like this battery pack."
