10 Best Portable Charger Power Banks 2025 in the United States

This portable charger stands out with its built-in cables, which means you don’t have to carry extra cords for different devices. It includes three built-in output cables covering iPhone, USB-C, and Micro USB, plus three additional USB output ports, allowing you to charge up to six devices at once. That’s great if you have multiple gadgets or if you’re traveling with others. With a 10,000mAh capacity, it provides a decent amount of power to recharge most smartphones about two times, which is suitable for daily use or short trips. Its slim and lightweight design (about the size of a large smartphone and weighing under 9 ounces) makes it easy to carry around without adding bulk.

A handy digital display shows the exact battery percentage remaining, so you won’t have to guess when to recharge the power bank itself. Speaking of charging, it supports three types of input ports, giving flexibility in how you recharge the power bank. The product is widely compatible, working well with popular phones like iPhones, Samsung, Google Pixel, and more.

While 10,000mAh is good for everyday use, it might not be enough if you need to recharge large devices or multiple gadgets many times over. Also, some users might find the built-in cables less durable over time compared to separate cables. This power bank represents a solid choice for people who want a neat all-in-one charger, especially travelers or those who often juggle different devices and prefer not to carry extra cables.

This portable charger offers a solid 15,000mAh capacity, making it suitable for charging smartphones, tablets, and other small devices multiple times on a single charge. Its standout feature is the built-in cables for various common connectors (USB A, Type-C, iOS, and Micro), which means you won’t need to carry extra cables—a real convenience for travel or daily use. It supports fast 22.5W charging, which helps charge your devices quicker than standard power banks, although it’s not the fastest speed available in the market.

With six output ports, including a bi-directional Type-C port, it can power multiple devices simultaneously, ideal for users with several gadgets or families on the go. Despite its capacity and multiple ports, it remains compact and lightweight, easily fitting in a pocket or bag, and features a handy lanyard for carrying. The smart LED display clearly shows how much charge remains, so you can plan your usage without surprises. Safety is well-covered with protections against overheating and overcharging, plus it meets airline standards for air travel.

While 22.5W is fast, it may be slower than some high-end models offering 30W or more, and the built-in cables, while convenient, might wear out faster than detachable ones. Also, for users needing ultra-high capacity or heavy device charging, 15,000mAh might fall short. This power bank is a versatile and user-friendly option great for everyday use, travel, and multi-device charging without extra cable hassle.

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.
