10 Best Portable Phone Chargers 2025 in the United States

The INIU Portable Charger stands out with its 10000mAh capacity, which is ample for multiple charges of most smartphones, making it great for weekend getaways. Its slim and lightweight design (only 0.5 inches thick and weighing 8.8 ounces) makes it highly portable, easily fitting into pockets or small bags.

The inclusion of a USB-C port that supports both input and output is a notable feature, increasing compatibility and convenience for users with various devices. The charger offers 3A high-speed charging, which can significantly reduce the time needed to power up your devices. Safety is also a priority, with a 15-layer SmartProtect system to prevent overheating and battery damage.

Additional features like a built-in flashlight add extra utility, making it handy in emergencies. However, with only one USB-A to USB-C cable included, you might need to purchase extra cables for simultaneous charging of multiple devices.

The Anker PowerCore 10K is a great choice if you want a portable charger that’s easy to carry around but still powerful enough to keep your phone and tablet charged. With a 10,000mAh capacity, it can fully charge an iPhone 15 twice or nearly twice for a Galaxy S23, which is handy for daily use or short trips. It’s impressively slim and lightweight, making it comfortable to slip into a bag or even a pocket.

The charger supports fast charging at 5V/3A thanks to Anker’s PowerIQ technology, so your devices get power quickly without long waits. It has two ports: one USB-C, which works for both charging the power bank itself and charging your devices, and one USB-A for other devices. This gives flexibility but only two devices can be charged at once, which might be a limitation if you need to charge multiple devices simultaneously. The build quality is solid, with scratch resistance and a drop test certification, so it should hold up well to everyday use.

One small downside is that while the fast charging is convenient, the capacity is moderate compared to larger power banks, so it’s best suited for light to medium use rather than extended trips without access to a power outlet. This makes it an excellent compact and reliable option for travelers or anyone who wants a no-fuss portable charger with good speed and decent capacity.

The Anker Portable Charger impresses with a 10,000mAh capacity, which is sufficient to fully charge most smartphones at least twice. It features 30W fast charging, meaning it can charge devices like the iPhone 16 Pro Max to 50% in just 27 minutes – significantly faster than traditional chargers. This makes it highly efficient for users who need quick boosts of power, especially on the go.

The built-in USB-C cable is a convenient feature, designed to withstand over 10,000 bends, enhancing its durability for daily use. Despite its power, the charger remains compact and lightweight at 7.7 ounces, making it a practical travel companion. The bi-directional charging capability allows for both charging your devices and recharging the power bank itself quickly, with up to 30W output and 20W input.

It only includes one built-in USB-C cable and an additional port (one USB-C and one USB-A), which might limit simultaneous charging of multiple devices. Additionally, users who need to charge multiple high-drain devices like tablets and laptops frequently might find the 10,000mAh capacity somewhat limiting. It also comes with an 18-month warranty and friendly customer service, which adds peace of mind for potential buyers.
