Portable Charger

INIU's slim 10000 mAh bank is popular for simple reasons: it is about half an inch thick, budget-priced, and takes USB-C in and out, so one cable handles phone, headlamp, and bank. For a weekend, or a five-day trip with the phone in airplane mode, it carries enough. Two things to understand before buying. The 10000 mAh figure is raw cell capacity, not what reaches your phone; after voltage conversion, expect roughly 6,000 to 7,000 mAh of usable output, which is two full phone charges rather than three. And the slim model tops out at 5V/3A, so there is no high-wattage USB-C PD here. Refilling the bank itself during a town stop takes hours, and it will not fast-charge a modern phone. At 195 grams it is also not the ultralight answer; gram-counters who accept a 5000 mAh bank save half that weight.
