This Nitecore CARBO 10000 powerbank is a really lightweight, super small powerbank. It only weighs 157 grams and yet has a capacity of 10,000 mAh. This powerbank features a ´Unibody Shell Construction´. That means that the body of the powerbank is made from one piece of CFRP (Carbon Fibre Reinforced Polymer). As such, the powerbank is incredibly strong yet lightweight. This powerbank is 200% more pressure-resistant than the original Nitecore NB10000. Perfect for when you´re travelling or backpacking!
