10 Best Portable Charger Power Banks 2025 in the United States

The INIU Portable Charger is a slim and lightweight power bank with a 10000mAh capacity, making it a practical option for travelers and daily use. It can charge devices multiple times, such as topping up an iPhone 8 up to 3.6 times or a Samsung S22 nearly twice. It is exceptionally thin at 0.5 inches, fitting easily into pockets or bags without adding bulk, and weighs just 7 ounces.

The charger features three output ports (one USB-C and two USB-A), enabling you to charge multiple devices simultaneously. Additionally, the USB-C port can be used for both input and output, offering versatile charging options not commonly found in other power banks. This can be particularly useful if you already use USB-C devices and cables. With a 3A high-speed charging capability, it can significantly reduce the time needed to charge your devices, which is a big plus for people on the go.

Its 15-layer SmartProtect system ensures safe charging by preventing overheating and battery damage. One of the additional features includes a built-in flashlight, which can be handy in an emergency. However, it is important to note that while this power bank offers many strengths, it might not be the best choice if you need to charge power-hungry devices frequently, as higher capacity options (larger than 10000mAh) might be more suitable. Additionally, its sleek and slim design, while convenient, may make it less durable compared to bulkier models. In conclusion, the INIU Portable Charger is well-suited for those who need a compact, reliable, and fast-charging option for everyday and travel use.

This can be particularly beneficial for travelers or those who carry multiple gadgets. Additionally, the power bank offers six output ports and three input options, allowing you to charge up to six devices simultaneously, a feature that is quite handy for multi-device users.

In terms of portability, its slim design and light weight (about 0.55 lbs) make it easy to carry around, fitting comfortably in a pocket or purse. The LED display is a helpful addition, providing a clear indication of the remaining charge, so you know exactly when it needs recharging. A potential downside might be its charging speed; while it offers 3A fast charging, this might not be the fastest option available and could be a consideration for those who need rapid charging capabilities. The universal compatibility is a plus, as it supports both newer and older devices across different brands.
