- Nintendo Switch (18W max)

The integrated USB-C cable—typically found on pricier models—eliminates the need to carry separate cables. The clever design allows the USB plug to clip onto the unit as a convenient lanyard. Both cable and lanyard boast impressive durability, with 44-pound and 13-pound break strengths respectively.
