10 Best Fastest Portable Chargers For Iphone 2025 in the United States

The Anker Laptop Power Bank stands out with a very large 25,000mAh capacity, which means it can charge your iPhone 15 or 16 multiple times and even handle bigger devices like MacBooks. Its three USB-C ports each provide up to 100W power, allowing fast charging for multiple gadgets at once—great if you carry an iPhone and a laptop or tablet together. The built-in cables, including one retractable and one short carrying strap cable, add convenience by reducing the need to bring extra cords. It also includes a USB-A port to connect older devices.

Despite this power, it stays within airline rules for carry-on batteries, making it suitable for travel. At about 1.3 pounds and roughly 6 x 2 inches, it's portable but a bit on the heavier and bulkier side compared to smaller phone-only chargers. If you want a fast charger that can handle multiple devices including laptops, this is a solid choice, though it might be more charger than needed if you only want to power an iPhone. The digital display and fast recharge speed (30% in 22 minutes) add practical benefits, while the 18-month warranty and positive customer reviews suggest good reliability.

This power bank is best suited for users who need powerful, versatile charging on the go and don’t mind a slightly larger size.

The Anker MagGo Power Bank is a robust portable charger specifically optimized for iPhone users, particularly those with the iPhone 12, 13, 14, and 15 series. With a 10,000mAh capacity, this power bank can securely provide up to 1.8 charges for an iPhone 15 Pro, making it a reliable option for extended use away from a standard power source. Its 15W wireless charging capability, Qi2 certified, ensures fast and efficient charging, capable of bringing an iPhone 15 from 0 to 50% in just 44 minutes. This is particularly beneficial for users needing quick, reliable power boosts on the go.

The smart display is an intuitive feature that keeps users informed about the charging status, including battery percentages and estimated recharge times, enhancing user experience by eliminating guesswork. Additionally, the built-in foldable stand allows for hands-free viewing, making it convenient for media consumption or video calls while charging. However, it's important to note that while this power bank can charge Android devices like Samsung and Google phones, they won't benefit from the magnetic feature or the full 15W charging speed, thus charging at lower efficiency.

The compact size (3.94 x 2.76 x 0.79 inches) and relatively lightweight build (8.8 ounces) make it portable and easy to carry, although it might not be the most lightweight option available. The Anker MagGo Power Bank is well-suited for iPhone users who value fast, efficient wireless charging, and convenient additional features like a smart display and foldable stand.

The Baseus Laptop Power Bank offers a strong package for anyone needing a fast, portable charger, especially if you use an iPhone 16 or 17 series. Its 20,800mAh capacity means you can charge an iPhone about three and a half times, which is plenty for a full day or longer without access to a plug. What really stands out is its high output power—up to 145W total, with 100W available on a single USB-C port. This means it can charge not only smartphones but also larger devices like MacBooks very quickly. It supports four devices at once with two USB-C and two USB-A ports, which is great for travelers or those carrying multiple gadgets.

Despite the high capacity, it stays TSA-approved for flights since its rated capacity is just under the typical 100Wh limit. It’s compact and reasonably lightweight at about 1.15 pounds, roughly the size of a soda can, so it won’t add much bulk to your bag. The digital display is a helpful touch, letting you see the remaining battery and charging speed at a glance.

While powerful, to get the fastest laptop charging you need a high-quality 100W USB-C cable, sold separately, which adds to the cost. Additionally, if you frequently charge multiple devices at once, the 145W total output will be shared, reducing charging speed per device. For iPhone users focused on fast, reliable charging and willing to carry a slightly larger power bank, this Baseus model represents a solid choice. However, if you want something ultra-light or only ever charge one phone at a time, smaller power banks might be easier to carry.
