Jump to: Our Verdict / Features / Specifications

The NPB1 Power Bank is a lightweight, slim, and waterproof power bank that can charge a phone fully once. It can also hold charge in very low temperatures, making it ideal for hiking and backpacking.

Nitecore says: 

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).

Our Verdict

NPB1 Power Bank is a lightweight, slim power bank with two key features that set it apart from other power banks I have used for hiking. These make it much more user-friendly and are tailored to life on the trail.  

It is incredibly light and capable of charging my phone fully once, so I can go around two days "off-grid" if I am using it sparingly. I primarily use my phone navigation, an audiobook at camp and the occasional photo. You may use your phone more or less, so that should be considered.

Firstly it's waterproof; it can even charge when submerged I do not intend to charge my phone whilst underwater, but that level of waterproofing instils confidence when backpacking. The knowledge that it will still work if this gets wet is a huge draw for me. 

The other key feature is the charger's ability to hold charge in very low temperatures. Most electrical products do not like freezing temperatures and quickly lose charge if exposed to these conditions. However, the Nitecore holds its charge down to -10.
