Nintendo Switch (16Wh): ~3.7 charges Steam Deck (40Wh): ~1.9 charges Apple iPhone 16 (14Wh): ~4.2 charges Apple iPhone 16 Plus (18Wh): ~3.3 charges

The power bank includes three ports: two USB-C and one USB-A. Its 22.5W Power Delivery can charge a Nintendo Switch or Switch 2 even during gameplay, as both typically draw under 20W in handheld mode. It's also relatively compact for a 20,000mAh model, measuring 4.8" x 2.8" (though it is a chunky 1.2" thick) and weighing about 11 ounces. A convenient built-in USB-C cable means one less accessory to carry.
