Nitecore NB10000 Power Bank GEN4

The Nitecore NB10000 Power Bank GEN4 pairs a carbon-composite shell with 143g of weight and 10,000mAh of capacity — figures that put it among the lightest power banks at this capacity. USB-C connectivity with PD fast charging up to 22.5W keeps both the bank itself and whatever you're charging from it topping up quickly. An IP67 rating adds dust protection and brief submersion resistance, a step above the IPX4–5 ratings typical of travel electronics in this category. The carbon-composite shell keeps weight down without a major durability trade-off, so it survives being tossed in a pack's side pocket or a camera bag without much worry. Built for thru-hiking, alpine use, and travel, it targets situations where you need to recharge a phone or camera away from power while keeping the added weight in your bag to a minimum.
