A slim, unibody carbon-fibre brick that is airline ready, weatherproof and built to take a drop on the trail.
The CARBO 10000 is moulded from a single unibody carbon-fibre reinforced polymer shell, the same family of material used in aerospace and motorsport for its strength-to-weight. The seamless construction has no spliced joins, so there are no weak seams to split when the pack gets dropped or crushed in a bag.
CFRP is lightweight, corrosion resistant and high strength, so the cell inside rides in a case that shrugs off the knocks of a long trip rather than cracking at the edges.
The unibody structure gives the CARBO 10000 more than 200% of the pressure resistance of the NB10000, tested in the Nitecore lab. Bury it under a loaded pack, sit on your bag at a trailhead or wedge it into a stuffed carry-on, and the shell holds its shape.
Carbon fibre also damps micro-vibration, so charging keeps running clean whether you are scrambling over rock or jogging a fire road.
The high-protection unibody shell raises impact resistance to 1.5 metres, so a slip out of a jacket pocket or a tumble off a camp table is a non-event. The scratch-resistant surface keeps the weave looking sharp through a season of complex outdoor use.
That is the kind of toughness you want from the one battery keeping your phone, GPS and headlamp alive miles from a socket.
At 157g and just 11.5mm thick, the CARBO 10000 carries roughly 45% lighter than a conventional 10,000mAh power bank of the same capacity. It slides flat into a hip-belt pocket, a jacket chest pocket or the map sleeve of a pack rather than weighing down the bottom of it.
For anyone counting grams on a long route, that is real capacity you barely notice carrying.
The built-in cell reaches an energy density of 243.9mWh/g, around 16% higher than conventional 18650 Li-ion batteries. That density is how the CARBO 10000 fits a full 10,000mAh into a body this slim and this light.
You get the capacity of a full-size bank in something that feels closer to a phone in the hand.
10,000mAh covers roughly 2.3 full charges for an iPhone 14 Pro, or about 1.5 for a Huawei Mate 50 Pro, so a phone at 8% deep into a trek gets back to full with charge to spare.
It also tops up the rest of your kit: around 4.5 charges for a Nitecore UT27 headlamp, or 1.5 charges for a 3,500mAh Li-ion cell, keeping your GPS and lights running through a long ultra.
Dual ports let you fast charge two devices at once with QC and PD support, automatically matching each device. The USB-C port delivers up to 20W out and refills the bank at 18W in, while USB-A pushes up to 18W to a second device.
Recharge from the same USB-C wall plug your phone already uses, then run a phone and a headlamp together from one pack.
Long-press the mode button to switch into low current mode on either port, and a white indicator confirms it is active. It feeds a steady trickle suited to earbuds, smartwatches and fitness bands that a fast-charge bank can otherwise refuse to charge or switch off on.
One pack handles the phone in your hand and the wearables on your wrist.
The CARBO 10000 is rated IPX5, so it stands up to rain and a sustained low-pressure water jet. A downpour on an exposed ridge or a splash at a stream crossing is something it takes in its stride.
It is sealed for weather rather than submersion, which is exactly the protection a pack-carried power bank needs out on the trail.
At 38.5Wh the CARBO 10000 sits well under the 100Wh carry-on limit and meets the UN38.3 standard, so it travels in your hand luggage and clears the gate with ease.
Slim and discreet, it slides into a carry-on or a jacket pocket, ready to top up a phone the moment you land.
An onboard circuit watches for overcurrent, short circuit, over-discharge, overcharge, overvoltage and excess heat, stepping in before any of them reach your devices. It is the reassurance you want from a battery you leave charging your phone overnight in a tent.
A unibody carbon-fibre shell takes a 1.5m drop and more than double the crush resistance of an aluminium-bodied NB10000, where a typical plastic bank cracks.
A full 10,000mAh at 157g and 11.5mm thin, about 45% lighter than a conventional bank of the same capacity. Real charge you barely feel in the pack.
QC and PD fast charge up to 20W out and 18W in over USB-C, so it tops devices quickly and refills itself fast between adventures.
IPX5 weatherproofing and UN38.3 airline approval mean it handles a downpour on the trail and a security check at the airport with equal ease.
157g of carbon-fibre capacity that disappears into a hip-belt pocket and keeps your phone and GPS alive for days off-grid.
IPX5 weatherproof and 1.5m impact resistant, ready for rain on a ridge and the odd drop on rock.
Slim enough to ride flat in a jacket pocket, with a low current mode for your earbuds and watch.
UN38.3 airline approved and well under 100Wh, discreet in a carry-on and ready to charge on landing.

Yes. At 38.5Wh it sits well below the 100Wh carry-on limit that airlines apply to lithium batteries, and it meets the UN38.3 transport standard. Carry it in your hand luggage rather than checked baggage, the same rule that applies to every power bank.
The unibody carbon-fibre shell is moulded in one piece with no spliced seams, which is why it survives a 1.5-metre drop and resists more than double the crushing pressure of the aluminium-bodied NB10000 in Nitecore lab testing. It also resists scratches and corrosion, so it holds up to seasons of outdoor use rather than scuffing or cracking.
The CARBO 10000 is covered by an 18-month free warranty, with a 15-day free replacement period for any out-of-box issue. Register your purchase and keep your receipt to make any claim straightforward.

Good buy👍feel good n rugged. Very compact n handy. I love it Best can add on the Triple ' C' icon printed at back. There some explanation need to do at China customs. ""The power bank look so attractive to have. @ security checkpoint risk to be confiscate bcoz of confiscation 😅
Handy and compact. Fast charging for its size. 👍🏻
Item was quickly shipped and received within 2 days. Had a little issue when i received it, but the CS was very prompt to resolve the issue, i appreciate the quick action & help of the CS. Thanks, good job. I strongly recommend to buy Nitecore NB Air if there is a need for a light weight powerbank to carry around, the light weight made a difference for me. Thanks Nitecore.
Modern look with firmly interaction. Good choice for me
Light and convenient to carry around.
Good product. Love it !
The Nitecore NB10000 Gen 4 is an incredibly sleek and compact power bank. Its carbon-fibre casing makes it extremely lightweight, and the built-in USB-C cable cleverly doubles as a lanyard. The illuminated ports are a cool and practical touch, making it easy to connect your device even in the dark. The surface also seems quite scratch-resistant so far. It provides roughly 1.5x full charges for my iPhone 16 Pro Max, which is impressive for something this small and light. Definitely worth the money.
Extremely small and light. Doesn't even look like a power bank. I bought it because of its compact size and its aesthetics fitted with a carbon fiber case. It can charge my iPhone 16 pro from 7% to 80ish% within an hour. And it can be used two times before it’s completely drained. Down side is the cost. It’s a-bit pricey I would say but totally worth it. Highly recommended.
very small and light. can charge my phone twice which will get me through 50k no worries
Order received within 36 hours. Item was well packed although there were some damages ro the box. Hopefully able to last long.
Product Quality:looks good, should be authentic Best Feature(s):lightweight af Value For Money:absolutely not, but it's fancy Delivery was quick. Product looks and feels pretty good, lights and lanyard are a nice touch. Dont know why they market it as CARBON FIBRE SHELL. It's clearly just the sticker lol
Finally a powerbank that I feel safe to use in weather. Looking forward to my next ultras.
Love the power bank
Sleek and compact design. Excellent
Love the weight and compactness. Charging time is reasonable
Very compact and lightweight to carry around.
Build quality:Well made Weight:Power bank impressively light Charging speed:Have not try
yet another good solid product from Nitecore :) I have a good selection of Nitecore's flashtlights , batteries accessories from my prevous purchases :) they never fail to deliver!! Good job !
Love its compact size, that fit the small pouch perfectly.
waited for quite sometime for this and it was worth it. light and reliable.
Bought this light weight powerbank for a friend who love travel as a gift.
It is incredibly light and compact. As compared to my Apple magnetic charger as shown here, it is just slightly longer but everything else is better. Can charge my iPhone 14 Pro Max faster too. I’ll be switching to daily-ing this instead.
Not the fastest (Output = 18W), nor the most powerful (rated power = 3300mAh) but perfect as my day out ultralight minimalist carry. Uses a 3.88V high-voltage Li-ion battery compared to the typical 3.6V one found elsewhere. They're likely more expensive (?) but this allows the battery to stay thin and small Can be found elsewhere at less than half the asking price ($31/RM98), maybe even lower? You might lose the local warranty (why do you need one for a cheap powerbank?) but you'll gain the 3C certification that'll allow you to bring this battery into plane/train when you're in China. Buy this for portability, not for power users
Lighter but works similar to my current power bank. Loves it!
Super light and delivery was quick!
Build quality:Good Weight:Lightweight Charging speed:Fast charge Simple, no-fuss design. One port, straightforward operation—nothing complicated, which many users appreciate
The Gen4 NB10,000 by far exceeded expectations with lightness, compact barely felt any weight. Good for standby, emergency situation arises
Is very light, the lightest 10kmah I’ve ever seen. The touch swipe to turn on is cool! But I wish there’s additional wireless magnetic charge feature added on this power bank will make it the best of the best.
Best Feature(s):Ultra-light, durable and waterproof. Product Quality:Great for hikers. Value For Money:A bit expensive but worth to have it.
My NITECORE NB Plus – I took it with me on my travel recently. In between rest and sightseeing I tried out and charged my iPhone. It works perfectly, in lesser time than I expected and no fuss about. My iPhone’s outdoor companion! Brgds Ray C Thurs, 26Feb2026
