10 Best Portable Battery Chargers For Cell Phones 2025 in the United States

The Belkin Portable Charger offers a substantial 10,000mAh capacity, providing up to 31 additional hours of power for your iPhone, making it a solid choice for long days or trips. The integrated Lightning and USB-C cables simplify your life by eliminating the need to carry extra cables, and its 23W output allows you to charge two devices simultaneously. This is particularly useful for users who need to keep multiple devices powered up throughout the day. The pass-through charging feature is handy, letting you charge your phone while the power bank itself is recharging.

An LED indicator helps keep track of the charge level, ensuring you know when it’s time to recharge the power bank itself. The compact size (6 x 2.5 x 1 inches) and weight (10.2 ounces) make it relatively portable, although it might feel a bit bulky for some users. It's not the lightest option out there, but the built-in cables and reliable performance could justify the size and weight for many. If you have an older device that doesn’t support USB-C, you might find this power bank less convenient.

For those who travel frequently or need reliable backup power for their devices, this Belkin charger offers a blend of capacity, convenience, and multi-device support.

The Charmast Power Bank 20000mAh is a versatile and high-capacity portable charger suitable for a wide range of devices, including phones, tablets, and more. With its substantial 20000mAh capacity, it can charge devices like the iPhone 14 approximately 3.8 times and the Samsung Galaxy S23 Ultra about 2.5 times, making it perfect for users who need reliable power on the go. One of its standout features is the built-in multi-interface cables, which simplify the charging process by eliminating the need for additional cords and adapters. This makes it an excellent travel companion or daily use accessory for people who prefer convenience and efficiency.

With five output ports and four input options, it can charge multiple devices simultaneously and can be recharged using various methods, catering to heavy electronics users and those with multiple gadgets. The 20W PD fast charging capability ensures quick power-ups, reducing downtime and keeping users connected. Despite its high capacity, the Charmast Power Bank maintains a compact and slim profile, weighing only 0.73lb and measuring 6.33 x 2.85 x 0.74 inches, which is smaller and lighter than many other 20000mAh chargers on the market. Additionally, the LED display provides a clear and precise readout of the remaining battery percentage, taking the guesswork out of when to recharge.

The power bank requires two lithium polymer batteries (included), which might be a consideration for some users. Also, while it offers many features, the price point might be higher compared to simpler models. The Charmast Power Bank 20000mAh offers a blend of capacity, portability, and convenience, making it a strong choice for those in need of a dependable and feature-rich portable charger.

The Anker Nano Power Bank is a compact and handy choice if you need extra juice for your iPhone or other Apple devices on the go. Its 5,000mAh capacity offers a decent boost, roughly adding up to 20 hours of video playback on an iPhone 14 Pro Max, which is great for everyday use or short trips. One of its standout features is the built-in Lightning connector, so you don’t have to carry a separate cable, making it very convenient and pocket-friendly at just about 3 ounces and small enough to fit easily in your hand or pocket. It supports 12W fast charging, which means your device will charge faster than with many basic power banks, helping you get powered up quickly. The MFi certification ensures it’s fully compatible and safe to use with Apple products, reducing the risk of connection issues or damage.

This power bank only has one built-in Lightning port and no additional USB outputs, so you can only charge one device at a time. Its 12W output is good but not the highest available, so if you have devices that support faster charging, this might not charge them as quickly as some other models. Also, since it’s designed mainly for Apple devices due to the Lightning connector, it’s less versatile if you want to charge non-Apple gadgets.

If you prioritize portability and convenience for Apple phones and don’t need to charge multiple devices simultaneously, the Anker Nano Power Bank serves as a solid and reliable option.
