Compact Power, Refined
The Nitecore NB10000 Gen4 is the next evolution of Nitecore’s ultralight 10,000mAh power bank, redesigned to deliver the same dependable capacity in a smaller, lighter, and more practical form. Weighing just 4.94 oz and sized for easy pocket or pack carry, it’s ideal for outdoor adventures, travel, and everyday urban use where space and weight matter.
Built for Real-World Use
Designed for demanding conditions, NB10000 Gen4 features a durable IPX7 water-resistant construction that handles rain, wet environments, and active use with confidence. Dual USB-C ports with up to 22.5W fast charging support efficient, flexible power delivery for modern devices on the go.
Simple, Smart, and Always Ready
The lanyard-style USB-C cable keeps charging always within reach and also makes the power bank easy to carry or secure while moving. Illuminated USB-C ports provide clear battery and charging status indicators, while pass-through charging allows devices to charge as the power bank itself is recharging. Rounded out with RGB port lighting and a knock-to-wake function for quick power checks, Gen4 delivers intuitive, reliable power for both trail and city life.

What People Are Saying
Mitchel K.Fenix HMR65R-T V2.0 Review
Super stoked on the new V2.0 version of this headlamp. The new ratchet system is a great improvement. The update headband is fantastic. And the purple colour scheme is super cool. I’ve owned multiple Fenix lights over the past few years and I won’t consider any other brand for future purchase. Happy customer.

Rob M.Pocket size protection
There are five reasons why I purchased this Klarus XT1C flashlight. It can be programmed for one button instant strobe. One,Defense from bears or people. Two, Offence, red light keeps you hidden at night. Three, USB-c battery usually an upgrade. Four, small pocket sized and five, Klarus is a good brand name.
