10 Best Iphone Battery Cases 2026 in the United States

The Anker 621 Magnetic Portable Charger (MagGo) is a compact and convenient battery pack designed specifically for iPhone 12 to 16 series users. With a battery capacity of 5,000mAh, it provides a decent boost for your phone on the go, making it particularly beneficial for those who frequently find themselves away from charging points. The product's unique MiniCell technology ensures that it's lightweight and fits easily in your pocket or bag, which is a significant advantage for users who prioritize portability.

One of the standout features is its strong magnetic attachment, allowing for a secure connection to the back of your iPhone. This design not only prevents disconnections during use but also makes it easy to operate your phone one-handed, which is a nice touch for multitaskers. The wireless charging capability simplifies the charging process; just snap it to your phone, and you're good to go. Users should expect some heating during use, which is typical for this type of device due to the efficiency of the charging conversion.

The 5,000mAh capacity may not fully recharge your iPhone from a low battery, especially on newer models with larger batteries. Those looking for a more robust solution might find this limiting. Additionally, while it's compatible with MagSafe, you might need to ensure your case is also compatible to maintain the magnetic connection.

The mophie Juice Pack Battery Case for the iPhone 16 is a solid choice for those looking to extend their phone's battery life while ensuring protection. With a built-in 2,800mAh battery, this case offers up to 50% extra power, making it great for heavy users who enjoy music, movies, and photography on-the-go. The slim design is a standout feature, making it easy to carry while providing enhanced drop protection for everyday mishaps. Weighing in at just 8.6 ounces, it doesn’t add much bulk, allowing your phone to fit comfortably in your pocket.

One of the unique aspects of this case is its magnetic compatibility, designed for secure attachment to compatible wallets and mounts. However, it does not support magnetic charging, which might be a downside for some users who prefer that convenience. Additionally, the priority plus charging feature ensures your iPhone charges first, giving you peace of mind that your device is powered up before the case itself.

On the sustainability front, mophie has made strides by using up to 50% post-consumer recycled plastics, appealing to eco-conscious consumers. The USB-C port for charging is another modern touch that adds to its versatility.

While the mophie Juice Pack excels in many areas, it may not be the best fit for everyone. Some users might find the price point slightly higher compared to other battery cases. Furthermore, while the protective features are commendable, those looking for maximum ruggedness might want to consider other options that offer even more robust protection. This battery case is ideal for those who prioritize extended battery life and a sleek, protective design, but it may not cater to everyone’s specific needs in terms of ruggedness and magnetic charging functionality.

The Mophie Juice Pack Battery Case for iPhone 16 Pro is designed to give you up to 50% extra battery life with its built-in 2,800mAh battery, which means longer phone use for things like music and videos when you're away from a charger. It fits the iPhone 16 Pro specifically, ensuring a snug and secure fit. The case has a slim and lightweight design that provides protection against drops from up to 6 feet, so it helps guard your phone without making it bulky or heavy (it weighs about 9 ounces).

One handy feature is the integrated magnet, which allows it to attach securely to compatible wallets, car mounts, or stands, although it doesn’t support magnetic charging itself. Charging is smartly managed so your phone gets powered first before the case recharges, helping to keep your phone ready to use. The case also uses eco-friendly materials, with up to 50% recycled plastic, and charges via a USB-C port, making it easier to use with modern chargers.

While it offers solid drop protection, it may not be as rugged as some bulkier cases if you need heavy-duty protection. It also doesn’t support wireless charging through the magnetic back, which some users might expect. Taking these points into account, this case is a good fit if you want a balance of added battery life, everyday protection, and convenience without adding much bulk to your iPhone 16 Pro.
