Nitecore NPB4 Power Bank

There’s no shortage of portable power banks on the market, but there are fewer focused on the Great Outdoors. The new Nitecore NPB4 is packed with features designed to embrace rough treatment in the field whilst still integrating all the latest technical specifications and functionality.

This 20,000 mAh Li-ion battery pack showcases multiple fast charge output ports (including USB-A, USB-C, and Micro USB) and will charge the latest iPhone 12 six times. A touch sensor power display indicates remaining battery life, and a number of protective safeguards ensure the charger continues to work between 14-104°F. The NPB4 is airline-approved, weighs just 13.33 ounces, and includes a nylon holster compatible with MOLLE tactical products. However, what sets this charger apart from the competition is that it’s IP68 rated and subsequently can be safely submerged in 2 metres of water for 30 minutes. As a sea kayaker, I can see this charger being a valuable failsafe should my communication/GPS device suddenly die and require charging at sea. As a general rule, electronics don’t enjoy many of the conditions associated with outdoor adventures, but the NPB4 promises to be a power bank you can depend on. Nitecore supports these claims with an 18-month warranty and a free replacement should you have any issues in the first 15 days.

The NPB4 integrates some innovative features whilst offering competitive charging performance. However, it’s the focus on durability that really differentiates this power bank from the alternatives. Being the “world’s first IP68 rated waterproof power bank,” makes the Nitecore a real contender in the overlanding/outdoors sector.
