Best Phone Battery Charger Cases of 2025

"The installation was a bit tricky, as I had to fold the top down more than usual, but it works well. Charging and using the battery case is easy. I'm glad I have better protection and longer battery life for my iPhone."

"I really appreciate the one-piece design and the USB-C charging feature. It has a comfortable grip and feels secure in my hand. I highly recommend this product!"

"I'm impressed with this case! The ones in stores are way too expensive, and this one is just as good. It does make my iPhone feel like a solid brick, but I love it!"

"I purchased four of these cases after a friend recommended them. My case and my mother-in-law's worked fine for the first three days, but my husband's never charged at all. We thought it was just a defective case, but it seems all of them are faulty! My phone overheated to the point where I feared it would catch fire! When charging overnight, my phone barely reaches 50%, while the case stays at only one bar. They feel like I’m carrying bricks in my purse! I will be contacting the shop for a refund!"

"I've owned a few of these cases over the years, and they really do a great job. I don't have to plug in my phone as often, and it keeps my phone charged all day. I just plug it in at night, and by morning, both my phone and the case are charged! The only downside is that it does make my phone a bit heavy."

"This battery case is a fantastic product! It significantly extends my phone's battery life, allowing me to use it all day without worrying about running out of power. The quality is impressive, providing solid protection for my phone, and I can charge both the phone and the case at the same time. The design is sleek, and it doesn't add too much bulk, making it a great accessory for anyone needing extra battery life!"

"As someone who is always on the go, I found this Battery Case to be a game-changer. The minimalist black finish caught my eye, and I love how it doesn't make my phone bulky. With a 7500 mAh capacity, it has saved me on long days filled with meetings. I can rely on my phone without hunting for a charger, and the case offers great protection from drops. Overall, I'm really happy with my purchase!"

"I purchased this case because my phone's standard charger failed. Instant gratification came when I put it on, as I haven't had to plug my phone in for over 48 hours! My wife is tired of me raving about it, but I can't help it! Even my in-laws are getting one. This case saved me from spending $400 on a repair!"

"I really love this case! While it does take some time to charge, the battery lasts a long time. I have two cases, so while one charges, I can use the other. It's been a lifesaver on trips, especially at places like Disney where charging isn't easy. I would 100000% recommend it!"

"I was really disappointed as it doesn't work with Apple earbuds. Customer service provided phenomenal assistance and sent me a new one quickly! Now, it works as expected without any issues!"

"This case was one of the best purchases I made. It fits perfectly on my phone and charges both the phone and its battery simultaneously. However, I can only use regular USB chargers, not USB-C fast chargers."

"After serious usage for 5 months, I wanted to increase my rating from 4 to 5 stars. This case has worked perfectly for me and has eliminated my concerns about battery life overnight."

"I love the high quality materials used in this product. It feels very durable and reliable!"

"Using it has been extremely easy; I figured it out right away without any hassle."

"Their customer support is impressive! They helped me quickly when I had a question."

"I found this battery case to be even better than I expected. It allows my phone to slide in or out easily, and I can always check the battery level at a glance. I primarily use it for travel, giving me the security of extra battery life whenever needed."

"I've had this case for a little under three weeks, and so far, it's working great! It charges alongside my phone at night, and I don't have to remove it or use a different charger. It can provide a full charge from empty and easily lasts all day, even with heavy use. Just be cautious when inserting or removing the phone, as the pin can bend easily."

"This battery case has been a game-changer for my long days. The capacity really makes a difference—I can get through an entire workday and still stream music during my commute without worrying about my phone dying. It fits my iPhone 14 Pro Max perfectly and adds extra power without making it too bulky. Plus, the rubberized edges offer added protection for my clumsy moments!"

"I absolutely love this battery case for my iPhone SE 2020. While it does add a bit of weight, it's far more convenient than worrying about battery life or carrying a separate charger. It charges my phone 2-3 times and data transfer works flawlessly. I usually charge it overnight since it takes a long time to recharge, but I don't have to stress about running out of power anymore!"

"This battery case is simply the best I've ever had! It charges my iPhone 6S from 20% to full in about an hour, and I still have 3 dots left on the charge scale. When it finally needs a refill, it takes less than 2.5 hours to recharge fully. I'm really impressed!"

"I got this for my grandson, who is always on his phone. This battery case feels just like a regular case while providing extra battery life. Since he relies on his phone for medical devices, I need it to stay charged. I don't worry about his battery anymore, as he can now go through the day without needing to recharge!"

"Happy new year everyone! I had to share my thoughts on this product because it truly is amazing. I bought one for my boss, and I was surprised by how slim it is for a 7500mAh battery. It fits my phone easily and offers ample screen protection. The charging speed is impressive, and it charges both the case and phone simultaneously. I was so impressed that I got one for myself and my fiancé too. This case is absolutely worth every penny, especially if you often forget to charge your phone overnight. I wanted to let others know that this product genuinely delivers on its promises!"

"I initially loved this case, using it as a portable battery pack while traveling. However, I found that the charging port doesn’t hold the cable securely, which can be frustrating. Despite this, the battery does a fantastic job keeping my iPhone 12 Pro charged to 100% for about 6 hours. It would be my go-to case if the connector was more reliable."

"This is my second purchase of this product. The first one lasted almost a year before it stopped charging my phone, even though the lights still illuminated. I thought it might be user error, so I bought another one in May, but I encountered the same issue again. If you’re looking for something long-lasting, I would suggest looking elsewhere. However, it works great while it lasts, especially if you upgrade your phone frequently."

"I absolutely love this charger! It works wonderfully and has double the battery life of my previous case. By the end of the night, I still have two bars left. Definitely recommend it!"

"I had a great experience with this product initially, but after a couple of weeks, the charging port became loose and it stopped working. However, for the price, I'm okay with replacing it every few months."

"This is a great product for casual use. It charges my phone two or three times, but as a mechanic, I noticed some peeling on the outer part. Still, I think it's reasonable for the price!"

"I appreciate the follow-up from the company regarding my complaint. This case is very durable and charges well; I definitely recommend giving it a try."

"Having used similar charging cases for years, I was disappointed when this one didn't charge my new iPhone 16 Pro at all. It lights up, but no charging occurs. I’m sending it back."

"This battery case is a fantastic addition to my phone accessories. With its 8500mAh capacity, it keeps my phone charged all day. I love the fast charging feature and the drop protection it offers."
