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 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.

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.
