Nitecore’s latest power bank is the lightest and most compact yet

Nitecore has released the NB10000 Gen 4, a 10,000mAh power bank marketed as the lightest and most compact in its class. The device features carbon fiber construction, IPX7 water resistance, and 22.5W output, making it ideal for outdoor enthusiasts.
Why it matters
It reflects the ongoing trend in consumer electronics toward miniaturization and high-efficiency power solutions for mobile users.
There’s two things you should know about me, your intrepid reviewer: I hate the feature creep associated with modern power banks, and I love shaving grams off the gear I carry when backpacking, bikepacking, and trail running. So imagine my delight when Nitecore released a new generation of its ultralight NB10000 battery. After a few weeks with it I can confidently say: Haribo be damned!
The $83.95 NB10000 Gen 4 weighs just 146 grams, according to my scale, and measures 1.45 x 11.6 x 4.68cm (0.57 x 4.57 x 1.84 inches), according to Nitecore’s spec sheet. That makes it the lightest and most compact 10,000mAh power bank I can find. Even when factoring in the extra 6 grams added by the included USB-C lanyard, it still beats the previous ultralight champ: Nitecore’s NB10000 Gen 3.
