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 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.

The Mophie Juice Pack Battery Case for iPhone 16e offers a solid solution for users needing extra battery life on the go. With a built-in 2,400mAh battery, it can extend your iPhone’s usage by up to 50%, which is useful for longer days away from a charger. It’s designed to be slim and lightweight at just 4 ounces, so it adds minimal bulk while still providing enhanced drop protection from up to 6 feet, helping to keep your phone safe from everyday bumps and falls. The case includes a magnetic back that works well with compatible wallets and mounts, although it doesn’t support magnetic wireless charging, which may be a downside if you were expecting that feature.

Charging is smartly managed through Priority Plus Charging, meaning your phone charges first before the case itself, ensuring your iPhone always gets power when needed. Made with up to 50% recycled plastic, it also appeals to eco-conscious users and charges conveniently via a USB-C port. However, the battery capacity is moderate, so heavy users might find it only gives a moderate boost rather than multiple full charges.

This case suits iPhone 16e users looking for a lightweight, protective battery boost with eco-friendly materials and magnetic compatibility for accessories. It may fall short if you want wireless charging support or very high-capacity backup, and while it offers decent protection, it might not be ideal for those needing rugged or waterproof features.
