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 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.

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.
