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 621 Magnetic Portable Charger (MagGo) is a compact and lightweight power bank, boasting a 5,000mAh capacity that's convenient for on-the-go charging. It uses Anker's MiniCell technology, allowing it to be smaller and lighter without compromising on charging performance. This makes it an excellent choice for those who prioritize portability and ease of use.

The strong magnets ensure it stays attached to the back of your iPhone (compatible with iPhone 12 through 16 series), making it handy for everyday activities like taking selfies or making calls. It’s designed to align perfectly with your phone, reducing the common issue of disconnection during wireless charging. However, users should be aware that slight heating can occur during use, which is normal due to efficiency losses in the conversion circuit.

The 5,000mAh capacity is suitable for partial charges or to extend your phone's battery life, but it may not fully charge your device multiple times. With its USB-C connectivity, it ensures fast and efficient input charging. Additional features include a 23.6-inch USB-C to USB-C cable, a 24-month warranty, and strong customer service support. On the downside, the device only offers one USB Type-C port, which might limit its use for charging multiple devices simultaneously. Weighing just 5 ounces and measuring 4.13 x 2.62 x 0.45 inches, it’s designed for ultimate portability.
