Nitecore NB10000 Gen 4 Power Bank

The Nitecore NB10000 Gen 4 is a 10,000mAh power bank weighing about 140 g, with dual USB-C ports — one for input, one for output. Fast charging is supported at up to 22.5 W, enough to top up a phone quickly rather than trickle-charge it overnight, and pass-through charging lets you charge the bank and a connected device at the same time from one wall outlet. At 140 g for 10,000mAh, it's a light option for backpackers who want a compact top-up without carrying a bulkier bank — for longer trips between charging opportunities, a higher-capacity option like the NB20000 will last further before needing a refill.
