10 Best Portable Charger Power Banks 2025 in the United States

The Anker 621 Magnetic Portable Charger (MagGo) is a compact and lightweight power bank with a 5,000mAh capacity, making it suitable for topping up an iPhone once or providing extra power on the go. Its standout feature is the built-in strong magnets that attach securely to the back of iPhone 12 through 16 models, allowing wireless charging without worries about alignment and disconnection. This makes it very convenient for casual phone users who want a hassle-free charging experience without cables.

The charger uses USB-C for input, supporting faster recharge of the power bank itself. Weighing just 5 ounces and slim enough to fit in a pocket or purse, it’s designed for portability and ease of use. However, its 5,000mAh capacity is on the lower side compared to larger power banks, so it may not fully charge bigger phones multiple times or power other devices. Also, it lacks multiple output ports, meaning you can only charge one device at a time. Some users might find the wireless charging heat generation noticeable but within safe limits.

This charger is an excellent option for iPhone users who value convenience and portability over high capacity or multiple device charging.

The Charmast Portable Charger offers a solid 10,000mAh capacity, which is enough to recharge most smartphones about twice fully. A standout feature is its built-in cables—three different output cords cover iPhone, USB-C, and Micro USB devices, so you don't need to carry extra cables. It also boasts six output ports total, allowing you to charge up to six devices at once, which is handy if you have multiple gadgets or are traveling with others. Charging the power bank itself is flexible too, with three input options including USB-C and Micro USB, making it easy to recharge from various chargers.

In terms of size, it's super slim and lightweight, roughly the size of a large smartphone and weighing just over half a pound, so carrying it around daily or on trips won't feel bulky. A clear digital display shows exactly how much charge is left, helping you avoid unexpected power loss. Compatibility is broad—this charger works well with iPhones, Samsung phones, Google Pixels, and many other USB-C and Micro USB devices.

On the downside, while the 10,000mAh capacity is good for everyday use, it might be less suited for heavy users who need multiple full charges of power-hungry tablets or larger devices. Also, although it supports fast charging at 3A, the exact speed can depend on the device and cable used. Some users might miss wireless charging, which isn't included here. Lastly, the built-in cables are convenient but fixed length, which might limit flexibility in some charging setups. This charger fits best for people who value convenience and portability, especially those who often carry multiple devices with different charging ports. It's a simple, reliable solution for everyday use and travel, combining several cables in one slim package without extra clutter.

The INIU Portable Charger offers a solid 10,000mAh battery capacity, making it a good choice for daily use and short trips where you need to recharge your phone and other devices. Its standout feature is the dual USB-C ports that serve both for input and output, allowing you to charge the power bank and your devices with the same type of cable, which is quite convenient. One USB-A port is also included, so you can charge up to three devices at once—a nice bonus if you carry multiple gadgets. The 45W fast charging capability is impressive for a compact charger, letting you charge an iPhone 15 to 60% in just 25 minutes. This speed is helpful when you’re in a hurry.

The power bank is also notably lightweight and compact thanks to its high-density battery cell technology, making it easy to carry in a pocket or bag without much bulk. Additional perks include built-in indicator lights and a small flashlight, which can be handy in emergencies. On the downside, while 10,000mAh is enough for most smartphones once or twice, it might not be sufficient for heavy users or charging tablets multiple times. Also, although the power bank supports fast charging, the actual speed can vary depending on your device and cable quality. The 8.8-ounce weight is light but not the lightest in the market if you prioritize ultra-light gear.

This power bank is suited for users who want a reliable, fast-charging, and portable option with multiple ports for everyday use or travel. It may not fit those needing extra-large capacity or ultra-lightweight gear for extended trips.
