Size and Portability
The INIU power banks are surprisingly compact. The smaller 10,000mAh model is incredibly pocketable, easily fitting into any pocket, purse, or bag. Its size belies its power, making it ideal for on-the-go charging.

Even the larger 25,000mAh model, while more substantial, remains surprisingly portable. It's significantly smaller than I anticipated for its capacity, and still manageable to carry around all day. It's impressive how INIU managed to pack so much power into such a compact design.

Charging Capabilities and Speed
Both INIU power banks boast impressive charging speeds. The smaller model offers 22.5W fast charging, sufficient for most phones and tablets. The larger model, however, is a true powerhouse with its 100W output, capable of rapidly charging even laptops.

The 100W output allows for simultaneous charging of multiple devices at maximum speeds. I was able to charge my AirPods, iPhone, and MacBook simultaneously without any noticeable decrease in charging speed. The versatility is a major advantage.

Build Quality and Design
INIU power banks feel robust and well-made. The matte finish on the larger model is pleasant to the touch and resists fingerprints well, though the glossy screen can attract smudges.

The inclusion of a small stand on the smaller model is a nice touch, allowing for convenient phone charging. Overall, the build quality inspires confidence in the product's durability and longevity.
Conclusion and Verdict
Both INIU power banks offer excellent value for money. The smaller model provides a great balance between size, speed, and capacity for everyday use. The larger model, while pricier, is a true beast, easily powering multiple devices at impressive speeds.

The INIU power banks are a testament to well-engineered design and functionality. While the larger model’s capacity is technically a limit for air travel, I highly recommend the smaller model for its sheer portability and power, whereas the larger is a luxury option for travelers needing multiple device charging simultaneously. For their performance, compact size, and build quality, they are a worthwhile investment.
