The Nitecore NB10000 Gen4 is a newly redesigned ultralight power bank that packs a full 10,000mAh into a body weighing just 4.94 ounces — about the size of an energy gel. It’s built for anyone who wants to keep a phone, headlamp, or GPS charged on the trail or at camp without hauling a heavy brick. Here’s what’s actually new about the Gen4 and whether it’s worth it.
QUICK TAKE: The Nitecore NB10000 Gen4 is a 10,000mAh power bank that weighs under 5 oz, charges most phones about twice, and survives rain thanks to an IPX7 waterproof rating. New Gen4 upgrades include dual USB-C ports, 22.5W fast charging, a knock-to-wake battery check, and a lanyard that doubles as the charging cable.
Who It’s For
Any camper, hiker, or traveler who needs reliable power away from an outlet but doesn’t want to carry a heavy battery. It’s a favorite among backpackers and ounce-counters because of its weight, but the appeal is broad: car campers, festival-goers, road-trippers, and everyday commuters all benefit from a pocketable bank that charges a phone twice and shrugs off rain.
What’s Actually New
Most 10,000mAh power banks weigh 220-280 grams — a real brick in your pack. The NB10000 series has always been the ultralight exception, and the Gen4 refines it further into a smaller, slimmer body at just 4.94 oz. The upgrades that matter: dual USB-C ports (so you can charge and recharge at once with pass-through charging), 22.5W fast charging, a carbon-fiber shell for durability, and IPX7 waterproofing that handles rain and wet conditions. Two clever touches stand out — a knock-to-wake feature that lights up the battery indicator when you tap it (usable even with gloves), and a lanyard that doubles as a USB-C charging cable, so you always have a cable attached and one less thing to forget.
The Catch
Two honest points. First, capacity is deliberately modest: 10,000mAh charges a typical phone about twice, which is plenty for a weekend but not for powering a whole group or a week off-grid — for that you’d want a larger power station. Second, it charges one main device at a time efficiently; it’s a personal-carry bank, not a base-camp hub. Buy it for what it’s best at: ultralight, reliable, keep-your-essentials-charged power you’ll actually bring instead of leaving behind.
