10 Best Portable Battery Chargers 2025 in the United States

This portable charger offers a 10,000mAh capacity, which is a solid middle ground for daily use, providing roughly two full charges for most smartphones. Its standout feature is the built-in cables—three output cables (including Lightning, USB-C, and Micro USB) and one input cable—which means you don’t need to carry extra cords, making it very convenient for travel or busy days. With six output ports in total, you can charge up to six devices at once, which is excellent if you have multiple gadgets or are sharing with others. It also supports three different input options for recharging the power bank, adding flexibility.

The slim and lightweight design, about the size of a lighter and weighing less than 9 ounces, makes it easy to carry around in a pocket or bag. The digital LED display showing the exact remaining battery percentage is a useful touch to avoid surprises about power levels. It’s compatible with a wide range of devices from iPhones to Samsung and other USB-C or Micro USB products. A 10,000mAh battery might be limiting if you want to charge larger tablets multiple times or rely on it for extended trips without recharging.

This charger suits everyday users who value convenience, multiple device charging, and portability, but those who need heavy power capacity or advanced safety certifications may want to consider other options.

This portable charger stands out with its built-in cables and multiple ports, making it very convenient if you dislike carrying extra cords. It has 3 built-in output cables (for iPhone, USB-C, and Micro USB) plus 3 additional output ports, allowing you to charge up to six devices at once—great for people with several gadgets or families on the move. The 10,000mAh capacity is solid for daily use, usually enough to recharge a smartphone about two times fully.

It’s also super slim and lightweight, roughly the size of a small phone and weighing just over half a pound, which makes it easy to carry in a bag or pocket. The digital LED display showing the exact battery percentage is helpful because it prevents guessing when you need to recharge the power bank. Charging speed is supported up to 3A fast charging, so devices can charge reasonably quickly, although it’s not the fastest available if you have very high-power phones. The three input options to recharge the power bank itself add flexibility, which is a nice touch.

The build quality appears decent, with a neat and slim design, though users expecting rugged or waterproof protection might want something more robust. This charger suits travelers or anyone juggling multiple devices who wants a tidy, all-in-one solution without carrying extra cables. For everyday convenience and compatibility with almost all popular phones and tablets, this power bank performs well, though those needing more power capacity or ultra-fast charging might consider other options.

The Anker 20,000mAh portable charger is a strong choice for anyone needing reliable, fast charging on the go. Its large capacity can keep multiple devices powered through a day or more, which is ideal for travelers, commuters, or users with several gadgets. The standout feature is its 87W total power output, allowing rapid charging of laptops like the MacBook Pro, as well as fast replenishment for phones including the iPhone 15 series, Samsung models, and even gaming devices like the Nintendo Switch. Having three output ports plus a built-in USB-C cable adds convenience, reducing the number of cables you need to carry. The built-in cable is designed to last through frequent use without wear, which is a nice touch for durability.

The power bank itself is fairly compact and lightweight, making it easy to pack or carry around. Charging speed is also impressive, both for your devices and for refilling the power bank itself with a compatible 65W charger. Anker's reputation for solid build quality and the inclusion of safety features to protect your devices from overcharging or overheating provides extra peace of mind.

On the downside, while having a built-in cable is convenient, it might limit compatibility with some less common devices that don't use USB-C. Also, if you need to charge more than three devices at once or want wireless charging, this model doesn't offer those options. The size, while portable, is not the smallest power bank available, so it might feel a bit bulky if you prefer ultra-compact gear. This Anker power bank presents a great balance of power, speed, and durability for most users needing a dependable travel charger for multiple devices.
