10 Best Portable Power Banks

The INIU Power Bank offers a strong 20,000mAh capacity, which should provide about a full week of charges for most smartphones, making it great for travelers or anyone needing reliable backup power. It supports 22.5W fast charging with modern PD 3.0 and QC 4.0 technologies, allowing your phone to reach around 61% charge in just 30 minutes, which is notably quick for a power bank in this range. The USB-C port is versatile, serving both as input and output, so you can both charge the power bank and your devices with the same cable type—a handy feature as USB-C is becoming the standard. Additionally, with two USB-A ports alongside the USB-C output, you can charge up to three devices at once, which is convenient for sharing power or charging multiple gadgets simultaneously.

The power bank weighs about 363 grams and measures roughly 13.5 x 7 x 2.5 cm, which is somewhat bulky compared to smaller models, so it’s better suited for backpacks rather than pockets. Its build includes high-quality materials and safety features, backed by a 3-year warranty, giving good peace of mind against overheating or short circuits. The LED display helps you easily monitor the remaining battery.

A potential drawback is that while 22.5W charging is fast compared to many power banks, it doesn't reach the very highest speeds some newer models offer (like 30W or above), so charging very power-hungry devices might be slower. Also, the weight and size mean it’s not the lightest option if ultra-portability is a priority. For users seeking a reliable, safe, and versatile power bank capable of charging multiple devices quickly and efficiently, this model remains a solid choice.

The UGREEN Magsafe Power Bank offers a solid 10,000mAh capacity, enough to fully charge most modern smartphones at least once, making it suitable for daily use or short trips. One of its standout features is the magnetic wireless charging, which provides up to 15W fast charging without cables, perfectly aligning with compatible iPhones (like the iPhone 15 and 16 series) thanks to its strong magnets and a non-slip surface. This wireless convenience adds ease but is limited to devices supporting MagSafe.

Additionally, it has a USB-C port delivering 20W power, enabling fast wired charging for multiple devices simultaneously, which is great if you need to charge your phone and another gadget at the same time. The input charging speed is also 20W, so the power bank itself can recharge quickly, reducing downtime. Weighing just 222 grams and slim at around 1.3 cm thick, it’s highly portable and pocket-friendly, ideal for carrying around without bulk.

Safety-wise, it includes protections against overcurrent, overvoltage, short circuits, and overheating, ensuring your devices and the power bank stay safe during use. The use of airline-friendly materials is a bonus for travelers. The wireless charging output is capped at 15W, which is decent but not the fastest compared to some competitors. Also, it supports only two output methods: wireless and one USB-C port, so if you need more ports or different types like USB-A, it might be limiting. This power bank suits iPhone users who value wireless charging and need a lightweight, fast-charging portable battery with solid safety features.

The INIU 22.5W Power Bank offers a solid 10,000mAh capacity, making it a practical choice for typical daily use—enough to charge a smartphone multiple times without being bulky. It stands out for its fast charging support with 22.5W output using modern PD 3.0 and QC4+ technologies, which can recharge compatible phones up to twice as fast as standard chargers. The inclusion of USB-C for both input and output is convenient, as this port type is now common on many devices including recent iPhones, iPads, and Android phones. This dual USB-C setup also helps speed up recharging the power bank itself.

At 210 grams and with a slim, compact design that's notably thinner and lighter than similar models, it’s easy to carry in a bag or pocket without feeling heavy or awkward. Safety seems well-covered with high-grade materials and a notable 3-year warranty, which adds peace of mind. It also supports trickle charging for small devices like AirPods, helping to protect their batteries.

The 22.5W output, while fast, is on the modest side compared to some higher-wattage power banks that can charge tablets or laptops faster. The battery size is good for everyday smartphones but might fall short if you want to charge larger devices multiple times or power-hungry gadgets. The built-in phone holder and flashlight are useful extras but may not be essential for all users. This power bank represents a dependable, easy-to-use option for anyone seeking a balance of portability, safety, and decent fast charging for modern phones and small devices.
