10 Best Portable Power Chargers 2025 in the United States

The INIU Portable Charger offers a good balance of portability and power. With a capacity of 10000mAh, it can recharge an iPhone 8 up to 3.6 times or a Samsung S22 about 1.8 times. One of its standout features is its slim design, measuring only 0.5 inches thick, making it very easy to carry in a pocket or bag.

The charger is equipped with a USB-C port that supports both input and output, which is rare in the market, and includes two additional USB-A ports, providing versatility for charging multiple devices simultaneously. It also supports 3A high-speed charging, allowing for faster recharge times compared to standard 2.1A chargers. The safety features are robust with a 15-layer SmartProtect system to prevent overheating and battery damage.

On the downside, while the charger is lightweight at 7 ounces, it might still feel a bit heavy for some users who prioritize ultra-light travel gear. Additionally, it offers a flashlight feature which might be redundant for some users. Despite these minor drawbacks, the INIU Portable Charger is an excellent option for those seeking a reliable, high-capacity, and portable power solution.

The INIU Portable Charger offers a robust 20000mAh capacity, making it ideal for extended use, potentially lasting up to a week without needing a recharge. This is particularly beneficial for travelers or those who frequently use their devices on the go. It boasts 22.5W output power with Power Delivery (PD) 3.0 and Quick Charge (QC) 4.0 technology, ensuring fast and efficient charging. You can charge an iPhone 13 up to 52% in just 25 minutes, which is notably faster than many standard chargers.

The charger has multiple ports, including USB Type C and USB Type A, allowing you to charge various devices simultaneously. This versatility is great for users with multiple gadgets like smartphones, tablets, and smaller accessories such as AirPods or smartwatches. It's relatively lightweight at 12.8 ounces and compact with dimensions of 5.3 x 2.8 x 1 inches, making it easy to carry in a bag or pocket. Additional features include LED indicator lights and a built-in flashlight, adding to its practical use in various situations.

Some users may find the size slightly bulkier compared to smaller capacity power banks. The charger comes with a USB C cable, travel pouch, and a welcome guide, supported by a 3-year warranty and lifetime technical support, which reflects confidence in its durability and user satisfaction. Although it is manufactured in China, its popularity suggests it meets consumer expectations in the portable power charger category.

The Miady 2-Pack 10000mAh Dual USB Portable Charger offers a reliable and convenient power solution for users of various smartphones, including iPhone, Galaxy, and Pixel models. One of its major strengths is its capacity; at 10000mAh per charger, it's enough to fully charge most smartphones at least twice. The inclusion of USB-C fast charging is a significant advantage, especially for modern devices, although it's worth noting that a lightning cable for iPhone users isn't included in the package.

The dual USB output ports (5V 2.4A) allow for simultaneous charging of two devices, which is a handy feature for multitaskers or travelers with multiple gadgets. The compact and slim design makes it highly portable, weighing just 218 grams, and its grippy texture ensures it's easy to handle and carry around. The use of Li-polymer cells enhances safety and reduces weight further, making it airplane-friendly. Additional features like auto shut-off and LED indicator lights add to the user-friendly experience.

However, some potential drawbacks include the absence of a lightning cable for iPhone users, and the charging speed, while decent, is not the fastest available on the market. The Miady charger is a solid choice for those seeking a balance of capacity, portability, and convenience.
