The standalone 6,000mAh Carbon Battery 6K. The same battery as the Headband Kit, sold on its own for SGD $59, so you can pair it with a headband or headlamp you already own.
The single USB-C port puts out 5V/2A, so the 6,000mAh pack tops up a phone, camera or any USB-C device. That is close to a full charge for most phones from a battery that disappears into a jacket pocket.
Drop it in your bag for a day out and you have a meaningful top-up ready at the car park or the trailhead, with charge to spare for your headlamp at night.
Plug the Carbon Battery 6K into a compatible Nitecore headlamp with a USB-C cable and the lamp draws from the 6,000mAh pack first, holding its own internal cell in reserve. You get up to 2x the usual runtime on an NU40.
Run a headlamp straight through a long night out, then still have its built-in battery ready when the pack runs flat. One charge covers sunset to sunrise on most trail runs.
A red safety light sits on the body, facing behind you when you wear or clip the pack. Hold the power button for one second to switch it on, and drivers, cyclists and the runners behind you pick you out well before they reach you.
It is the visibility a road-side walk home or a night trail wants, built into the battery you are already carrying.
The carbon-fibre reinforced shell packs a 6,000mAh cell into a body that weighs just 88g, about the weight of a small chocolate bar. That works out to 15.4g of structure around a 72.6g cell, an energy density of 245.5Wh/kg.
You carry hours of extra light and a phone top-up while barely noticing the weight in a pocket or pack.
An IP68 rating means the pack keeps dust out and stays sealed when submerged to 2m, so a dropped-in-the-creek moment or a downpour is a non-event. Rinse it clean under the tap after a muddy trip and carry on.
The carbon-fibre shell also takes a 1m drop in its stride, so a rugged battery does not have to be a heavy one.
It tops up a phone like any bank, and feeds a compatible Nitecore headlamp through USB-C for up to 2x the runtime. A generic bank only charges between uses.
A built-in red rear light keeps you visible from behind on the road. An ordinary power bank does nothing for your safety in the dark.
88g of carbon fibre for 6,000mAh, about the weight of a small chocolate bar. Most pocket banks of this capacity weigh noticeably more.
Sealed to IP68 and submersible to 2m, with a 1m-drop carbon shell, where a typical bank wants to stay dry in a bag.
When the pack is connected, compatible headlamps switch into Performance Mode, which eases the rate at which brightness steps down so output stays more stable over time. The trail ahead holds a consistent level of light instead of fading as the hours add up.
For a night run or a long approach, that means fewer dim patches and a beam you can trust deep into the dark.
A short press of the power button lights three red indicators that read out the remaining charge at 100, 70 and 30 percent. You know before you set off whether the pack has a phone top-up and a night of headlamp runtime left in it.
Hold the same button for a second and those indicators become the rear safety light, so one button covers both jobs.
A steadier headlamp beam deep into a night run, with a red rear light for the road sections home.
Up to 2x the headlamp runtime for a long descent, plus a phone top-up for GPS when the screen runs low.
Hours of light from one charge, IP68 sealing for dew and rain, and USB-C to keep devices going.
A pocket-sized phone top-up for the commute that doubles as headlamp power for the weekend.

No. This is the standalone Carbon Battery 6K, the bare battery on its own, which is why it is priced below the kit. If you want the widened headband and bracket to wear it on your head, choose the Carbon Battery 6K Headband Kit instead. This version suits buyers who already have a headband or headlamp, or who want it purely as a power bank.
It powers the Nitecore NU40, NU43, NU45, NU50, NU53, HC60 UHE, HC65 UHE and HC70 UHE through their USB-C ports. Runtime gains depend on the model, up to 2x on the NU40, 1.6x on the NU43, 1.3x on the NU50 and 1.2x on the HC65 UHE. You supply a USB-C to USB-C cable, as one is not included.
A short press of the power button lights three red indicators at 100, 70 and 30 percent so you can check the remaining charge. Holding the button for one second switches on the red rear light for visibility, and it stays off otherwise to preserve charge.
The standalone battery ships on its own. A USB-C cable and headband are not included. For the headband and bracket, choose the Carbon Battery 6K Headband Kit.

Weight:Light weight and small to carry around without much added bulk. Durability:Waterproof with nice carbon construction makes it a good daily carry and surviving rough use. Fast delivery from Shopee. First powerbank from Nitecore and I am pretty impressed by it. But the only downside is that Nitecore doesn't even provide a basic short cable out of the box which most other powerbank would give.
Weight:very light weight and very nice grip to hold Durability:material feels very solid that can last for years to come paired it with nitecore nk10link cable looks awesome together, definitely my everyday use power bank for now on, firmly recommend it to everyone. delivery is fast and packed nicely as-well thanks alot nitecore sg
Weight:Lightweight Durability:Quality built An excellent choice for anyone who values portability and reliability. Its ultra-lightweight carbon fiber design makes it incredibly easy to carry around, whether you’re commuting daily or heading outdoors. At just around 88g, it’s noticeably lighter than most power banks in its class.
