Nitecore’s latest power bank is the lightest and most compact yet
Nitecore has launched the NB10000 Gen 4, a 10,000mAh power bank aimed at backpackers, cyclists and endurance athletes who prioritise low weight and small size. The Verge found it to be the lightest and most compact power bank in its capacity class, though its £84-equivalent price and some unnecessary design choices limit its appeal.
The 146g battery measures 1.45 × 11.6 × 4.68cm and uses a silicon-carbon anode to increase energy density. It delivered 33.58Wh in testing—86.1 percent of its claimed 39Wh capacity—enough to fully charge an iPhone 15 Pro twice, while also supporting up to 22.5W output, pass-through charging and IPX7 water resistance. The reviewer noted improved low-charge reliability over the previous model, but criticised its inconsistent touch control and RGB lighting.
In short
- Nitecore’s new 10,000mAh power bank is exceptionally light and compact.
- It offers strong efficiency, water resistance and laptop top-up capability.
- High price and fussy controls are its main drawbacks.
Explained simply
Power banks store electricity so people can recharge phones and other devices away from a mains socket. Their capacity, weight and size affect how many charges they can provide and how easy they are to carry.
Nitecore is a maker of portable power and lighting equipment. Its NB10000 range is designed for people such as backpackers, cyclists and endurance athletes, who may need to keep devices charged while travelling or exercising.
A 10,000mAh capacity is a common size for a portable charger, so weight and dimensions can help distinguish models in this category. Water resistance and charging speed may also matter when a power bank is used outdoors.
