Customer Reviews
Overall rating: 4.9 / 5 from 399 reviews.
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
