10 Best Iphone Battery Cases 2025 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 Anker 622 Magnetic Battery (MagGo) is a compact and lightweight battery case designed specifically for the iPhone 13 through 16 series, offering a battery capacity of 5,000mAh. This capacity provides a decent amount of extra power for daily use, helping extend your phone’s battery life without adding much bulk. One of its strong points is the seamless magnetic alignment with the iPhone’s MagSafe feature, making it effortless to attach and ensuring a stable wireless charging connection without the hassle of cables. The charger also includes a USB-C port on the side, allowing for wired charging if preferred, which adds versatility.

Its ultra-slim profile, only half an inch thick and weighing about 5 ounces, makes it easy to carry in a pocket or bag without feeling heavy or awkward. The built-in foldable kickstand is a nice touch, allowing you to prop up your phone for hands-free video calls or streaming, which is great for convenience at home or on the go. However, while the design is sleek and portable, it doesn’t offer much in terms of rugged protection, so if you’re looking for a battery case that also shields your phone from drops or impacts, this might not be the best fit. Charging speed is decent for a portable charger but not particularly fast compared to some larger battery packs.

The product comes with a 24-month warranty and good customer support, reflecting Anker’s reputation for reliability. This battery case is ideal for users wanting a lightweight, magnetic, and easy-to-use charging solution that enhances battery life without adding bulk or complexity, but it’s less suited for those needing heavy-duty protection or very rapid charging.

The Mophie Juice Pack Battery Case for iPhone 16 Pro Max offers a solid boost to your phone’s battery life, providing up to 50% extra power with its built-in 3,600mAh battery. This means more time for music, videos, or calls without hunting for a charger. It’s designed specifically for the iPhone 16 Pro Max, ensuring a snug fit and compatibility. The case is slim and lightweight, weighing under 10 ounces, which helps keep your phone easy to carry without feeling bulky.

It also provides enhanced protection, able to absorb shocks from drops up to six feet, which is great if you want to safeguard your device from everyday bumps. A handy feature is its integrated magnet, allowing you to attach your phone securely to compatible wallets or mounts, though it doesn’t support magnetic wireless charging itself. Charging is straightforward with a USB-C port, and the Priority Plus charging feature makes sure your iPhone charges before the case, so your phone battery gets topped up first. Another plus is the eco-friendly design, made partly from recycled plastics, which is a nice touch for sustainability.

The case adds protection but might still feel a bit heavier than a regular case, and the magnetic back is limited to attachments, not charging. Also, it’s specifically made for the iPhone 16 Pro Max, so it won’t work with other iPhone models. If you want more battery on the go with protective benefits and don’t mind a slightly heavier case, this Mophie Juice Pack is a good option to consider.
