Nitecore has introduced its latest portable power solution, the NB10000 Gen 4, which redefines the standards for lightweight and compact external batteries. This innovative device is particularly suited for individuals who prioritize minimal weight in their gear, such as endurance athletes, backpackers, and bikepackers. Its design focuses on practicality and performance, making it a standout in a market often plagued by excessive features.
The NB10000 Gen 4 power bank is remarkably light, registering at just 146 grams on a scale, and features an exceptionally slim profile, measuring 1.45 x 11.6 x 4.68 centimeters. These dimensions and weight make it the most compact and lightest 10,000mAh power bank currently available. Even with its integrated USB-C lanyard, which adds a mere 6 grams, it surpasses its predecessor, the NB10000 Gen 3, in terms of portability. This achievement is largely due to the integration of advanced silicon-carbon anode battery technology, a material increasingly found in high-end smartphones like those from Samsung.
Despite its small size, the Gen 4’s 39Wh battery offers substantial charging capabilities. In tests, it fully recharged an iPhone 15 Pro twice, retaining some residual power. Its impressive 22.5W output also allows it to top up larger devices, such as a 14-inch MacBook Pro, when necessary. Additionally, the power bank supports pass-through charging, enabling it to charge connected devices while simultaneously recharging itself. This feature is particularly useful for managing multiple devices on the go. The power bank's construction from carbon fiber sheets further enhances its durability and contributes to its minimal weight. It also boasts IPX7 water resistance, meaning it can endure rain and temporary submersion, a crucial characteristic for outdoor adventurers.
During testing, the NB10000 Gen 4 demonstrated high efficiency, delivering 33.58Wh out of its advertised 39Wh capacity, equating to an 86.1 percent efficiency rate. This marks a slight improvement over the Gen 3 model's performance. The energy density stands at an impressive 229.98Wh/kg, or 220.90Wh/kg when factoring in the cable, establishing it as a leader in its class. It supports multiple charging protocols, including PD, QC3.0, and Huawei's SCP, ensuring broad compatibility with various electronic gadgets. Unlike previous versions, the Gen 4 did not exhibit overheating or shutdown issues when power levels were low, though a brief interruption in power delivery was noted when almost fully depleted, quickly resuming normal operation. The device also includes animated RGB lighting around its dual USB-C ports, intended to assist users in low-light conditions. While these lights and a touch-sensitive wake button are present, they can be deactivated if desired. The power bank also offers a customizable eco mode, which reduces output to 5W to conserve energy and prevent automatic shutdowns for low-draw devices like headlamps or wireless earbuds, enhancing overall charge capacity by minimizing heat loss.
The Nitecore NB10000 Gen 4 is a prime example of superior engineering in portable power, combining class-leading energy density with an ultralight and compact form factor. While its price, at .95, is higher than many standard 10,000mAh power banks, the significant weight savings and robust features justify the investment for those who demand the best in portable outdoor technology.
