There's more to portable batteries than raw capacity. The pace of charging matters nearly as much and KeySmart's Ultimate Charger takes it seriously. Its various USB-A, USB-C, and Micro USB ports can quickly charge up to three devices at once, supporting charging output up to 65W — ideal for laptops. Its 20,000mAh capacity can juice up a laptop once, a tablet twice, or phones up to seven times, and its sleek metal shell slips easily into laptop bags and briefcases.
