Nitecore NB Air 5000mAh Power Bank

Tossed this in my running vest and honestly forgot it was there — 3.1 oz is barely noticeable compared to my old brick. The USB-C fast charging topped my phone up on a chilly 10-miler without a hiccup.

Three weeks into carrying this on every hike and it's basically disappeared in my hip pocket at 3.1 oz. The carbon fiber frame feels sturdier than the plastic brick it replaced, and USB-C refills it fast enough that I stopped noticing the wait.

Tossed it in my running vest pocket and forgot it was even there — the carbon fiber frame keeps it rigid without any bulk. Topped off my phone from 20% to full on a single trail run.
