Nitecore NB Air Ultra Lightweight and Slim USB-C 5000mAh Power Bank

The Ultralight battery for the Ultra Marathon Vest

I bought this to be a slim ultralight battery bank to put in my Salomon AADV Skin 12 runners vest for those long Ultras where I might need a top off for my Garmin watch and cell phone maybe even a headlamp. This battery is absolutely perfect for this scenario!! I love it and will be buying a few more for drop bags for my future Arizona Monster 300!

Ultralight, compact, perfect for backpacking and car camping. Charges iPhone fast! I’ll be using this one a lot.

I used this for a 50k trail race. It was light enough that it didn't add extra weight to my vest and charged my phone quickly.
