10 Best Lightweight Portable Power Bank 2025 in the United States

The INIU Portable Charger offers a reliable and portable solution for those who need a convenient power bank on the go. With a capacity of 10000mAh, it provides ample power to charge devices multiple times, such as an iPhone 8 up to 3.6 times and a Samsung S22 up to 1.8 times. The ultra-slim design, at just 0.5 inches thick, makes it exceptionally portable and easy to slip into a pocket or bag. This makes it ideal for travelers and everyday use alike.

One of its standout features is the USB-C IN&OUT port, which is relatively rare in power banks, allowing fast charging for a broader range of devices. Additionally, the power bank supports 3A high-speed charging, considerably faster than the more common 2.1A chargers, meaning your devices can be charged more quickly. Safety is also a priority with INIU, as the charger features a 15-layer SmartProtect system to prevent overheating and potential battery damage.

However, the product does have some minor drawbacks. Despite its slim design, the weight at 7 ounces might feel a bit heavy for some users who prioritize ultra-lightweight accessories. Furthermore, while it includes essential accessories like a USB-C cable and travel pouch, the relatively short cable might limit its practicality in certain situations.

The Anker PowerCore 10K is a great choice if you want a compact and light power bank that still holds a solid 10,000mAh capacity. It can comfortably recharge an iPhone 15 about twice and offers nearly two full charges for a Galaxy S23, making it handy for daily use or short trips. Its slim design and light weight (just under 9 ounces) make it easy to carry in a pocket or bag without adding bulk.

You get two output ports—a USB-C that doubles as input for faster recharging of the power bank itself, and a USB-A port—offering flexibility for different devices. Charging speed is decent with PowerIQ technology and 5V/3A output, so your phone won’t take forever to top up. The build feels sturdy and durable, passing a drop test from over 3 feet, plus it has scratch resistance, which is reassuring for travel.

A 10,000mAh capacity is enough for everyday needs but might be limiting if you want to charge multiple devices several times or larger tablets. Also, it doesn’t support wireless charging despite that being mentioned, so you’ll need cables. If you want a budget-friendly, reliable power bank that's easy to carry and charges quickly via USB-C, this Anker model is a solid pick, especially in a two-pack for sharing or backup.
