A featherweight carbon-fibre power bank with a hidden USB-C cable, 22.5W fast charging and an airline-friendly capacity.
At 12.5mm thick and 160g, the Pocket 10K slides flat into a jeans pocket or a jacket lining and stays there all day. It is about the footprint of a stack of cards, so a full day of backup power adds almost nothing to your everyday carry.
That slim profile is what makes a 10,000mAh bank realistic to actually have on you, rather than the brick that lives at the bottom of a bag.
The USB-C cable lives in the Pocket 10K itself, tucked flush along the edge until you flip it out. You grab the bank, plug straight into your phone and you are charging, with no loose lead to hunt for or leave behind on the desk.
The integrated cable passed 10,000 bending tests in Nitecore's lab, so the part you flex every day is built for the daily routine of pull-out, plug-in, fold-away.
The USB-C port delivers up to 22.5W with two-way PD and QC 3.0, and the built-in cable puts out up to 20W with two-way PD. A modern phone takes a meaningful top-up in the time it takes to grab a drink, so a quick stop is enough to get you home.
Two-way charging means the same 18W input also refills the Pocket 10K quickly, from the wall charger you already travel with.
Use the built-in cable and the USB-C port together to top up your phone and a friend's at the same time, or to share power across two of your own devices on a long day out.
Pass-through charging refills the Pocket 10K and your phone together from a single wall outlet, and an automatic low-current mode steps the output down for earbuds and a smartwatch, so small accessories charge safely on the same bank.
The 10,000mAh cell uses a high 241mWh/g energy density to pack a real day of backup into a flat carbon-fibre body. That is roughly 1.7 charges for an iPhone 16, 1.4 for an iPhone 16 Pro Max, and about 1.5 for a Galaxy S24.
At 38.5Wh it sits comfortably under the 100Wh carry-on limit, so it travels in your hand luggage for the flight and the days that follow.
Woven carbon-fibre sheets stabilise the cell and keep the whole bank light and stiff, while a sandblasted frame gives the sides a secure, anti-slip hold when you pull it from a pocket in a hurry.
The all-black carbon texture also wears well in daily carry, so it still looks the part after months of riding alongside your keys.
Smart circuitry guards against overcharge, over-discharge, overcurrent, overvoltage, short circuit and overheating, so you can leave it charging your phone overnight and trust it to manage itself.
It is rated to run in temperatures from -10 to 40 degrees Celsius, which covers an air-conditioned office, a humid afternoon and a cold-weather trip alike.
The Pocket 10K complies with the UN38.3 transport standard, so it is suited to carry-on travel for the flights between your trips.
IP65 sealing keeps dust and splashing rain out on a wet commute, and four blue LED indicators show charging status and remaining power, so a quick look tells you whether to top up before you head out.
A USB-C cable folds into the body, so you charge with one item in hand where most banks still need a separate lead packed alongside.
A card-thin carbon-fibre body sits flat in a pocket, instead of the chunky brick that only ever rides at the bottom of a bag.
IP65 dust and water resistance keeps it working on a rainy platform, where an unsealed bank wants to stay indoors.
At 38.5Wh it is UN38.3 compliant and well under the 100Wh carry-on limit, so it flies in your hand luggage with room to spare.
A flat 160g bank with the cable built in, ready in a pocket for the moment your phone dips into the red.
Fast charging for a quick platform top-up, and a sealed shell that handles a wet walk to the station.
A 38.5Wh capacity that travels in carry-on, with the cable built in so there is nothing to lose at the gate.
Charge two devices at once and refill earbuds in low-current mode, all from one pocket-sized bank.

Note: The built-in USB-C cable is not detachable. Not designed for underwater use. Dry thoroughly after exposure to moisture.
Yes. At 38.5Wh it sits well under the 100Wh limit airlines set for lithium power banks, and it complies with the UN38.3 transport standard. Carry it in your hand luggage rather than a checked bag, which is the standard rule for any power bank.
Yes. Pass-through charging lets the Pocket 10K refill from a wall outlet while it powers your phone at the same time, so one socket keeps both topped up overnight or at the airport.
Yes. An automatic low-current mode steps the output down for small accessories such as wireless earbuds and a smartwatch, so they charge reliably on the same bank you use for your phone.

My old power bank was bulky and I hated carrying an extra cable. This is slim, light, and always ready. The built-in cable is a small detail that makes a big difference.
I’ve gone through three power banks in the past year because of failing cables. This one has the cable built in and it's solid. No more replacements, just consistent charging.
Really thin. Fits into tight spaces in my pack.
