Never let your phone die! The NITECORE NB10000 power bank has an extraordinary 10,000mAh battery that can charge an iPhone 11 or Samsung s10 three times. Embodying all this power in a solid carbon fiber frame and case, the NB10K is 40% lighter than conventional power banks, while smaller and thinner than a phone, with a sleek modern minimalist design. The NB10k 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 a long search and rescue mission. It is also a great addition to your emergency prep kit or bug-out bag. NB10k is packed with features that put it way ahead of the pack. Its USB/USB-C dual QC output ports are compatible with a variety of electronics and allow you to fast charge two devices at once. For delicate devices such as Bluetooth headphones and smart watches, NB10k has a one-touch low current mode. Its lightweight yet strong carbon fiber case ensures that NB10k is highly resistant to puncture, abrasion, and impact. Additionally, the NB10k is IPX5-rated water resistant, and provides safeguards against short-circuit, overcharge, over-discharge, and overheating.
