Our take on the 40000mAh Power Bank with QC 4.0 and PD 30W Quick Charging

A high-capacity 40,000mAh lithium-polymer power bank with USB-C and Lightning ports, 30W PD output and QC 4.0 fast charging. The big cell count means several phone charges before it needs a refill, which puts it ahead of 10,000–20,000mAh packs on endurance but well behind them on size and weight. It suits travelers, campers and people who charge a phone and a tablet away from outlets. Owners rate it 4.1 out of 5; the common complaints are bulk and slower real-world charging than the 30W label suggests.
