Nitecore NB Air 5000mAh Power Bank

The Nitecore NB Air is a 5,000 mAh power bank weighing about 88 g, built around a carbon-fibre frame to keep weight down without giving up structural rigidity. Both input and output run through USB-C, and it supports fast charging, so a phone or GPS unit tops up quicker than on a basic 5V bank — useful when you only stop for a short break rather than overnight in camp. At 5,000 mAh it's enough for one to two full phone charges depending on the device, which suits day hikes, fastpacking, or as a backup top-up alongside a larger bank on longer trips — it's not sized to carry a phone, headlamp, and GPS through a multi-day stretch with no other charging option. For hikers prioritising low pack weight over maximum capacity, the 88 g figure is the main selling point.
