Nitecore has released the NB10000 Gen 4 power bank, which is not only the lightest but also the most compact in its class. Weighing just 146 grams, it’s designed for endurance athletes and backpackers who need to shave every gram of weight from their gear.

The battery holds a substantial 39Wh capacity and supports PD, QC3.0, and SCP charging protocols, making it versatile enough for most gadgets. Its impressive water resistance ensures it can handle rain or even being submerged in water temporarily.

However, the price point at $83.95 makes it a high-end choice, two to three times more expensive than typical 10,000mAh power banks. Yet, its weight savings and efficiency make it worth considering for those who value every ounce.

The Gen 4’s touch-sensitive knock-to-wake feature can be a bit hit-or-miss, with the RGB lighting being both useful in low-light conditions and unnecessary in others. Nevertheless, these features are customizable and can be disabled if preferred.

Overall, Nitecore has delivered a power bank that is perfect for those who prioritize weight over cost, making it an excellent choice for outdoor enthusiasts looking to carry light and stay powered up on the go.
