sentences:  The implementation allows a choice of three different voltages, providing power at 5 V (30 W), 12 V (72 W), 24 V (144 W) as well as a custom voltage.Some implementations provide 19 V or 25 V. The connectors are able to operate at up to 6 A (3 A per pin) peak, but according to the specification, hosts are required to provide a minimum sustainable rms current of 1.5 A at 5 V (7.5 W) or 12 V (18 W), or 2.3 A at 24 V (55.2 W), only.For comparison, a standard USB 1.x and 2.0 hosts supplies 5 V at up to 0.5 A (2.5 W).
