The Belkin BoostCharge Pro 20K is a 20,000 mAh power bank built for laptops as much as phones. One USB-C port delivers up to 65W, so it can run a MacBook Air or Dell XPS, and two more ports let it charge three devices at once. A full-color display shows battery percentage, per-device output and charging estimates, which most rivals in this class lack. Owners rate the speed and capacity highly, but some report units failing and note the glossy shell scratches and that it cannot charge and discharge at the same time.
