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

The Anker MagGo Power Bank is a slim and lightweight charger designed especially for iPhone 12 through 16 series, offering a strong 10,000mAh capacity that can charge an iPhone 15 Pro nearly twice. It supports ultra-fast 15W magnetic wireless charging, which is great for quickly topping up your iPhone without cables. There’s also a 30W USB-C port for wired charging, adding flexibility if you want to charge other devices or faster charge via cable.

Its compact size and light weight make it very easy to carry around, fitting comfortably in a pocket or bag. The power bank’s sturdy metal frame and thermal insulation help keep it cool and durable during use. However, the magnetic fast charging only works with compatible iPhones, so Android users won’t benefit from this feature and will experience slower wireless charging speeds. Also, while 10,000mAh is a solid capacity for portable use, heavier users who need multiple full charges may want something larger.

For those with a recent iPhone seeking a reliable, sleek, and fast portable charger offering the convenience of MagSafe compatibility, this Anker power bank represents a strong option. It is optimized for iPhones and may not provide the same experience with other phones.

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 621 Magnetic Portable Charger (MagGo) is a compact and convenient power bank designed specifically for iPhone 16, 15, 14, 13, and 12 series. Its standout feature is the 5,000mAh battery capacity, which provides a decent amount of charge for on-the-go use, although it may not fully charge larger battery phones multiple times. The use of MiniCell technology makes it smaller and lighter, and at 5 ounces, it's easy to carry around in a pocket or purse without adding significant bulk.

The strong magnetic attachment is very handy, ensuring the charger stays firmly attached to your phone, allowing for easy one-handed use. This is particularly useful for taking selfies or making calls while charging. The wireless charging feature simplifies the process, though users should be aware that slight heating is normal due to efficiency losses during the conversion process. The USB-C port type is modern and efficient, and the included 23.6-inch USB-C to USB-C cable is a nice addition.

Another benefit is the worry-free 24-month warranty and friendly customer service provided by Anker. However, it's worth noting that while the charger is highly convenient for short-term use, its 5,000mAh capacity may not be sufficient for heavy users who need multiple charges throughout the day. This product is ideal for iPhone users looking for a lightweight, portable, and easy-to-use charging solution with a magnetic attachment and wireless charging capabilities.
