10 Best Power Bank For Iphones 2025 in the United States

The Anker PowerCore 10K is a great choice if you want a compact and lightweight power bank mainly for your iPhone and other small devices. With a 10,000mAh capacity, it can charge an iPhone 15 about twice, which is enough for a day or two of moderate use away from a wall outlet. It supports fast charging with PowerIQ technology and outputs power at 5V/3A, meaning your iPhone will charge quickly compared to standard chargers. The USB-C port is versatile for both charging the power bank itself and charging your devices, plus there's a USB-A port for older cables. Its slim size and light weight make it very easy to carry in a bag or pocket. The build quality is solid with scratch resistance and a tested drop protection, so it’s durable for travel.

If you need to charge larger tablets multiple times or want extremely fast charging for bigger devices, the 10,000mAh may feel a bit limited. Also, it doesn’t support wireless charging despite the mention of wireless in features, which could be a downside for some users. This power bank provides a nice balance of portability, charging speed, and reliability, making it a smart pick for iPhone users who want a dependable, travel-friendly option.

The Anker 621 Magnetic Portable Charger is a compact and lightweight power bank designed specifically for iPhone users, with a 5,000mAh capacity that offers a decent amount of backup power without adding bulk. Its standout feature is the MagSafe-compatible design, using strong magnets to securely attach to the back of iPhone 12 through 16 models, making it easy to charge on the go without holding cables. This magnetic attachment also helps prevent the common wireless charging problem of misalignment. The included USB-C cable adds flexibility for wired charging when needed.

Weighing just 4.5 ounces and slim enough to fit in a pocket or purse, it’s highly portable and convenient for everyday use. The 5,000mAh capacity means it won’t fully recharge larger iPhone batteries multiple times, so it’s best suited for topping up rather than extended off-grid use. Slight heating during wireless charging is normal and worth noting.

With a 24-month warranty, this charger offers solid reliability. It is ideal for iPhone owners who want a portable, easy-to-use charger that sticks to their phone for quick power boosts, but those needing longer battery life between charges might want a higher-capacity option.

The Anker Power Bank with 20,000mAh capacity is a strong choice for iPhone users who need reliable portable charging. Its large capacity ensures multiple charges for your iPhone, making it ideal for longer trips or heavy usage. The power bank can charge three devices simultaneously, distributing 87W of power, which is great if you have multiple gadgets. It features two USB-C ports and one USB-A port, providing versatility for charging different devices. The built-in USB-C cable is a convenient touch, eliminating the need to carry extra cables and ensuring you always have one on hand.

Additionally, the cable is designed to last, withstanding over 10,000 bends, which highlights its durability. One standout feature is its fast-charging capability; it can charge an iPhone 15 Pro to 58% in just 30 minutes, which is impressive for users who need power in a hurry. The power bank itself can be fully recharged in 1.5 hours with a 65W charger, ensuring it's ready to go quickly. In terms of size and weight, it’s relatively compact (6.2 x 2.89 x 1.02 inches) and weighs 15.5 ounces, making it portable but slightly heavier than smaller-capacity power banks.

It includes safety features like overcharging protection and has a digital display for monitoring charge levels. Despite its higher price point, the robust features and reliable performance may justify the investment for users needing high-capacity, fast-charging solutions. However, if you prefer something lighter or less powerful, this might be overkill for your needs.
