The Nitecore NPB4 power bank features four next-generation 21700 Li-ion batteries, boasting a 20,000mAh capacity and an impressive energy density of 193mWh/g.

Engineered for waterproof durability, the NPB4 is equipped with a high-strength O-ring on the charging port, advanced glue-pouring technology to safeguard internal components, and fire-retardant PC materials for enhanced resistance to water and vapor.

With multiple fast-charge output ports, the NPB4 delivers a maximum output power of 18W. It packs enough energy to provide approximately six full charges for an iPhone 12, 32 charges for an AirPod charging case, and three charges for a portable gaming console.

The power bank also features a touch sensor power level display, indicating charge status with three lights for around 100%, two for 70%, and one for 30%.

For added safety and reliability, the NPB4 includes multiple protective mechanisms, such as overcurrent protection, over-discharge protection, short circuit protection, and more.
