Never let your phone or vape die! The Nitecore NB10000 power bank has an extraordinary 10,000mAh battery that can charge a base iPhone 11 or a Samsung s10 three times. Embodying all this power in a solid carbon fiber body frame, the NB10K is 40% lighter than conventional power banks, while smaller and thinner than a phone, with a sleek modern minimalist design. The NB10000 is the ultimate portable backup battery charger for road warriors, outdoor enthusiasts who enjoy trail running, hiking or camping, or first responders who are on an extended search and rescue mission. It is also a great additional to your emergency prep kit or bug-out-bag.
