10 Best Portable Power Banks 2025 in the United States

This portable power bank is equipped with a 10000mAh capacity, which is sufficient for multiple charges of most smartphones. One of its standout features is the built-in cables, reducing the need to carry separate charging wires.

With six output ports and three input options, it offers versatility for charging a variety of devices simultaneously. The slim design and lightweight make it highly portable, akin to carrying an extra phone. The digital LED display is a useful addition for monitoring the remaining battery percentage, eliminating the guesswork.

Fast charging capability ensures your devices power up quickly, which is a significant plus for heavy users on the go. Compatibility is a strong suit, as it supports a wide range of devices including iPhones, Samsung phones, Google Pixel, and many other USB-C and Micro USB devices. However, the presence of only a 10000mAh battery capacity might be limiting for those who require extended use without frequent recharging. Additionally, while the built-in cables are convenient, they might not be replaceable if damaged. This power bank is an excellent choice for travelers and tech enthusiasts who need a compact, multi-functional charging solution with the convenience of built-in cables.

The Anker PowerCore 10K is a slim and lightweight portable power bank with a 10,000mAh capacity, making it a solid choice for daily use and travel. Its size and weight are highly convenient—it’s easy to carry in a pocket or bag without feeling bulky, which suits people who need power on the go. The device offers two charging ports: one USB-C port that serves as both input and output for faster charging and one USB-A port, allowing you to charge two devices at once.

It supports 5V/3A high-speed charging, which means it can quickly recharge smaller devices like iPhones and some Android phones, but it might not be the best for fast charging larger tablets or laptops. The power bank is durable and drop-tested for reliability, which helps if you’re often outdoors or traveling. It does not include wireless charging, so if you require that feature, you will need to consider other options.

With this capacity, the power bank can recharge an iPhone twice or a Galaxy phone nearly twice, but it provides about one full charge for an iPad mini, making it less suitable for extended power support for larger devices. This power bank is well-suited for everyday users seeking a compact, reliable charger for phones and smaller gadgets, though it may not meet the needs of those requiring higher power output or features like wireless charging.

The Anker 10,000mAh portable charger is a solid choice for anyone needing a compact and reliable power bank, especially for travel. Its 10,000mAh capacity is enough to fully charge most smartphones about two times, making it convenient for day trips or short outings. The standout feature is its 30W fast charging, which is notably quicker than average power banks, capable of charging an iPhone 16 Pro Max to 50% in just under half an hour. This saves you time when you’re on the go.

The built-in 5.4-inch USB-C cable is a smart addition, so you don’t have to carry extra cables, and it’s designed to be durable for everyday use. It also supports bi-directional charging, meaning the power bank charges quickly itself (up to 20W) and can charge various devices like iPhones, iPads, MacBooks, and even gaming devices such as the Nintendo Switch or Steam Deck. It includes one USB-C and one USB-A port, covering a range of devices, though if you have older iPhones, you'll need to bring your own Lightning cable.

Weighing just 7.7 ounces and measuring about 4.3 by 2.6 inches, it’s lightweight and easy to carry in a bag or pocket. The capacity might feel limiting if you want to charge larger devices multiple times or share with multiple people simultaneously, since it has only two ports. The built-in cable is short, which might not be ideal in all situations. For those prioritizing fast charging, portability, and durability, this power bank is a fitting choice. It also comes with an 18-month warranty and positive customer feedback, adding peace of mind to your purchase.
