Nitecore NB10000 Gen 2 Review: 8.6/10 - Ultralight power bank for adventurers
Overview
The Nitecore NB10000 Gen 2 is a second-generation ultralight power bank that weighs just 5.3 ounces (150 grams) while delivering 10,000mAh of capacity. Built with a carbon fiber composite shell, it is designed for backpackers, thru-hikers, and travelers who count every gram. Despite its featherweight design, it offers 18W PD and QC charging for phones, earbuds, and GPS devices.
Design & Build
The NB10000 Gen 2 is remarkably thin and light, using a carbon fiber composite chassis that saves significant weight over traditional aluminum or plastic power banks. The carbon fiber weave is visible through the translucent coating, giving it a distinctive technical look. At just 0.43 inches thick, it slides easily into any pocket or pack pouch. The single USB-C and USB-A ports are protected by a rubber cover. The power button and four-LED charge indicator are minimal and functional. Build quality is exceptional, with a rigid structure that doesn’t flex.
Performance
The USB-C port delivers up to 18W Power Delivery, enough to fast-charge an iPhone to 50% in about 30 minutes or a Samsung Galaxy phone at full Super Fast Charging speeds. The USB-A port offers 18W QC 3.0 for compatible Android devices. While 18W won’t charge a laptop, it is the sweet spot for smartphones, earbuds, smartwatches, and GPS devices. The 10,000mAh capacity provides roughly two full charges for most smartphones. The power bank’s efficiency is high, with minimal energy loss during transfers.
Features
The carbon fiber construction is the standout feature, making this one of the lightest 10,000mAh power banks available. It supports pass-through charging, allowing the power bank to charge while simultaneously charging a connected device. The low self-discharge rate means it retains charge for months when stored. The 38.5Wh rating is well under airline limits. The IPX5 water resistance provides protection against rain and splashes, making it suitable for outdoor adventures. Nitecore’s reputation for high-quality battery products extends to this power bank.
