10 Best Portable Charger Power Banks 2025 in the United States

The Anker Laptop Power Bank offers a strong 25,000mAh capacity, making it well-suited for long trips or heavy device usage without frequent recharging. Its standout feature is the triple USB-C ports, each capable of delivering up to 100W power, which means you can charge multiple laptops or high-power devices simultaneously—a rare and useful option in portable chargers. Added to this are two built-in USB-C cables, one retractable and the other doubling as a durable strap, which reduces the hassle of carrying extra cables and is great for on-the-go convenience.

The power bank also includes a USB-A port, letting you charge up to four devices at once, covering a wide range of gadgets like smartphones, tablets, and gaming consoles. In terms of size and weight, it is reasonably compact at just over 6 inches long and weighs 1.31 pounds, so it is portable but still a bit heavier than smaller phone-only chargers. One limitation to note is its 90Wh rating, which is ideal for air travel carry-on but means it can't exceed that capacity due to airline restrictions. Charging the power bank itself is fast, with 100W input capable of reaching 30% charge in 20 minutes, saving you time between trips.

This power bank fits best for users who need reliable, powerful charging for multiple devices, especially laptops and newer smartphones, and appreciate the convenience of built-in cables. If you want something ultra-light or mainly for single device use, this might feel bulkier than necessary. It combines high capacity, fast charging, and thoughtful design for multi-device users who are often on the move.

The Anker Power Bank with a 20,000mAh capacity is a solid choice for anyone needing a reliable portable charger for travel or daily use. Its large battery can keep your devices powered for an extended time, which is especially convenient if you're away from outlets for a while. One standout feature is the built-in USB-C cable, which saves you from carrying extra cords and is designed to be tough enough to handle many bends.

The charger supports fast charging, delivering up to 87W across three devices, with one able to receive as much as 65W — this means it can quickly juice up not just phones like iPhone 15 or Samsung models but also larger gadgets like a 14" MacBook Pro. It even recharges itself fully in about 1.5 hours when using a 65W charger, which is quite efficient for a power bank of this size. The digital display helps you easily see how much charge is left, and safety features like overcharge protection add peace of mind.

On the downside, at 15.5 ounces and over 6 inches long, it’s a bit bulkier and heavier than smaller, lower-capacity models, which might be less comfortable for pocket carry. While it has three output ports, one is the built-in cable, so you don’t get three separate cables for different devices. This might limit flexibility if you want to charge multiple different devices without extra cables. This power bank is an excellent option for users who want a powerful, fast charger with convenience features and are comfortable carrying a slightly larger unit.

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.
