The Nitecore NPB1 power bank is equipped with a 5000mAh 21700 li-ion battery, providing an energy density of 173mWh/g. Compact and lightweight, the power bank can easily be stored in your pocket or backpack. 



With a waterproof rating of IP68, the NPB1 remains unaffected after 30 minutes of underwater submersion up to 2 meters, making it a reliable and durable power source whether you're caving, trail running or commuting. The charging port has a high strength, waterproof o-ring and advanced glue pouring technology ensures the components are kept safe inside the power bank. The unit is made from fire retardant PC materials and constructed by ultrasonic welding technology for extreme tightness against water and vapour. 

The NPB1 features a QC 3.0 output with a micro-USB and USB-A design making the charging process convenient for most devices, with a maximum output of 18W. 

To ensure you know how much power the NPB1 can offer, it has a touch sensor power level display. Simply tap the touch icon and the blue indicator will show 3 lights for 100% (approx), 2 lights for 70% (approx.) or 1 light for 30% (approx). 

The Nitecore NPB1 provides multiple protection safeguards, including:

  • Overcurrent protection
  • Short circuit protection
  • Over-discharge protection
  • Over-charge protection
  • Over-voltage protection
  • Thermal protection

The NPB1 includes a USB charging cable (USB-A to micro-USB).

We are unable to accept returned power banks once they have been opened.
