10 Best Battery Chargers 2025 in the United States

The Anker Power Bank is a 20,000mAh portable charger designed to meet the needs of users who require reliable and fast charging for multiple devices. One of its standout features is the impressive 87W total output, which allows for rapid charging of devices like the MacBook Pro and iPhones, making it a solid choice for both everyday users and professionals on the go. The built-in USB-C cable is particularly convenient, ensuring you don’t need to carry extra cables, and it’s durable enough to withstand over 10,000 bends, adding to its longevity.

This power bank is quite portable, making it easy to carry around, and it’s also airline-approved, so you can travel without worries about battery restrictions. The fast charging capabilities are another significant strength, enabling users to charge devices quickly, which is great for those with a busy lifestyle.

While the power bank offers great charging speed and capacity, it is a bit bulkier compared to smaller models, which may not be ideal for users looking for ultra-light options. Additionally, the need to share the total output with multiple charging slots can mean that charging several devices simultaneously may reduce the speed for each device slightly. Although safety features like overcharging protection are included, the reliance on a high-capacity battery means users should stay aware of using it responsibly to avoid any potential issues.

The Anker Power Bank is a strong choice for anyone needing a reliable, fast-charging, and portable solution for their devices, especially for those who frequently charge multiple gadgets. It may not suit users who prioritize ultra-compact designs, but its performance and features make it a noteworthy option in the battery charger category.

The Anker 633 Magnetic Battery is a versatile and portable battery charger that stands out with its 10,000mAh capacity, making it suitable for users looking to charge their iPhones on the go. Its compact design allows for easy portability, which is great for travel or daily use. One of the key features is its wireless charging capability with strong magnets that align perfectly with compatible iPhones, ensuring a secure connection and efficient charging. Additionally, it supports high-speed charging through its 20W USB-C Power Delivery port, allowing users to charge their devices significantly faster than standard chargers.

While the magnetic feature is a strong point, it limits compatibility primarily to MagSafe devices, meaning users of non-MagSafe phones won't benefit from the same ease of use. The charger also has only a single charging slot, so it may not be ideal for users looking to charge multiple devices simultaneously. Although it includes safety features typical of reputable brands like Anker, such as overcharge protection, it’s important to ensure that the charger is used as intended to maximize safety.

The charger’s foldable stand is a nice touch, enabling hands-free viewing while your device charges, but it could be a bit more robust. The battery's weight of 7.7 ounces is manageable, but it may feel a bit heavier for those seeking ultra-light options. The Anker 633 Magnetic Battery is a great choice for iPhone users seeking a reliable, portable charging solution with the added benefit of wireless charging, but it may not suit those with other smartphone brands or those needing to charge multiple devices at once.

The Belkin Portable Charger is a solid option for those in need of a reliable power bank, especially for Apple devices like the iPhone. With a capacity of 10,000 mAh, it offers up to 31 hours of additional battery life, which is great for long trips or busy days. One of its standout features is the integrated Lightning and USB-C cables, making it a compact all-in-one solution that eliminates the need to carry extra cables.

With a total output of 23W, you can charge two devices at the same time, which is convenient for users with multiple devices. The pass-through charging feature is another benefit, allowing you to recharge the power bank while simultaneously charging your phone, saving time on charging. Additionally, the LED indicator light is a handy feature, letting you know when it’s time to recharge the power bank itself.

There are a few drawbacks to consider. While the 10,000 mAh capacity is decent, it may not be enough for heavy users who require even more power for extended periods. The design, while compact, may not suit everyone's preferences, especially considering it's slightly bulkier than some ultra-slim alternatives on the market.
