10 Best Portable Power Banks 2025 in the United States

The INIU Portable Charger stands out in the portable power bank category primarily due to its slim and lightweight design, making it one of the thinnest 10,000mAh power banks available. Weighing just 8.8 ounces and measuring only 0.5 inches in thickness, it’s an excellent choice for travelers who want to minimize bulk without sacrificing power. With the ability to charge devices quickly at 3A, it can recharge an iPhone up to 78% in just one hour, which is impressive for those in need of fast power-up during busy days.

One of the unique features of this power bank is its USB-C IN&OUT port, allowing it to charge both itself and other devices using the same cable. This is quite beneficial, as many power banks in the market only offer USB-C for recharging but not for device charging. The 15-layer SAFE charging technology also ensures protection against overheating and device damage, giving users peace of mind while charging.

On the downside, while the 10,000mAh capacity is sufficient for most smartphones, heavy users or those with tablets may find it limits their ability to charge multiple devices fully. Additionally, some users may prefer a power bank with multiple output ports, as this model features only one USB-C and one USB-A port, which can be restrictive for those needing to charge multiple devices simultaneously. The inclusion of a flashlight is a nice touch for emergencies, but some may find it unnecessary. The build quality is good, although it's always important to handle it with care, especially because slim devices can be more prone to damage if dropped.

The INIU Portable Charger is a solid choice for anyone needing a reliable power bank. With a 10000mAh capacity, it provides ample power to recharge various devices multiple times, such as an iPhone 8 up to 3.6 times or a Samsung S22 1.8 times. Its slim design, measuring only 0.5 inches thick and weighing 7 ounces, makes it highly portable and convenient for travel.

One of its standout features is the USB-C port that supports both input and output, offering versatility not commonly found in other power banks. Additionally, it includes two USB-A ports, allowing you to charge multiple devices simultaneously. The 3A high-speed charging capability ensures your devices get charged quickly, with the ability to fuel an iPhone up to 78% in just one hour. Safety is also a priority with INIU's 15-Layer SmartProtect system, which prevents overheating and potential battery damage.

The power bank comes with a few additional features like a flashlight and indicator lights, adding to its utility. Despite these strengths, the lack of wireless charging might be a downside for some users. Additionally, the included USB-A to USB-C cable is only 1 foot long, which may be inconvenient for certain situations. However, with a 3-year warranty and lifetime technical support, INIU stands by the quality of their product, making this power bank a reliable option for on-the-go charging needs.

This portable power bank is equipped with a 10000mAh capacity, which is sufficient for multiple charges of most smartphones. One of its standout features is the built-in cables, reducing the need to carry separate charging wires.

With six output ports and three input options, it offers versatility for charging a variety of devices simultaneously. The slim design and lightweight make it highly portable, akin to carrying an extra phone. The digital LED display is a useful addition for monitoring the remaining battery percentage, eliminating the guesswork.

Fast charging capability ensures your devices power up quickly, which is a significant plus for heavy users on the go. Compatibility is a strong suit, as it supports a wide range of devices including iPhones, Samsung phones, Google Pixel, and many other USB-C and Micro USB devices. However, the presence of only a 10000mAh battery capacity might be limiting for those who require extended use without frequent recharging. Additionally, while the built-in cables are convenient, they might not be replaceable if damaged. This power bank is an excellent choice for travelers and tech enthusiasts who need a compact, multi-functional charging solution with the convenience of built-in cables.
