Nitecore’s NB10000 Gen 4, weighing just 146 grams, combines high-capacity portability with ruggedness, targeting outdoor enthusiasts seeking reliable, distraction-free power solutions for hikes and adventures.
Nitecore’s NB10000 Gen 4 is a rare power bank that seems designed to remove distractions rather than add them. For readers who carry every gram on a bike, trail or long trek, that focus matters. The device costs $83.95 and weighs 146 grams on The Verge’s scale, making it one of the lightest 10,000mAh batteries available, even before considering its compact footprint and included USB-C lanyard cable. Nitecore says the battery uses silicon-carbon anode chemistry, which helps explain the size and weight savings.
In practice, that lightness does not come at the expense of usefulness. The Verge found the 39Wh pack could recharge an iPhone 15 Pro twice with some capacity to spare, and it is capable of delivering up to 22.5W, enough for modest top-ups of larger devices such as a 14-inch MacBook Pro. Nitecore also supports pass-through charging, so the battery can charge a connected device while itself is being recharged.
The hardware is intentionally simple. Instead of a full display, the unit uses a basic four-stage battery indicator. Its shell is built from carbon fibre sheets and it carries an IPX7 rating, meaning it should withstand rain and brief immersion in water. That makes it better suited to rough outdoor use than many generic power banks, which often prioritise screens, gimmicks or extra ports over resilience.
The Verge also reported solid efficiency. In testing, the battery delivered 33.58Wh from a claimed 39Wh, or 86.1 per cent efficiency, a slight improvement over the previous-generation model. The publication noted that this translated to class-leading energy density for the category. It also said the Gen 4 avoids the overheating and shutdown problems seen on the earlier version as it nears empty, although there was a brief interruption in power output when the unit was almost depleted.
There are still a few odd choices. Nitecore has added RGB lights around the USB-C ports and a touch-sensitive wake function, which The Verge considered less elegant than a physical button. The lights can help in low light, but the reviewer said the feature is partly redundant because the ports can be felt by hand. Even so, the company’s Eco mode, which limits output to 5W for low-draw devices such as earbuds and watches, adds practical value. For outdoor users who want a compact, durable battery with few compromises, the price is high but defensible.
