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.
