• USB 2.0 ports on computers, laptops, USB hubs and other such devices will commonly supply 500mA (0.5A) of power maximum, while USB 3.0 ports commonly supply 900mA.  This may not be enough for many applications.  This cable was designed to be used with wall chargers, USB rechargers and other USB adapters capable of providing 2A or more of power.
• ROCK64 boards can sometimes draw more than 2A of power. If your USB power supply cannot provide enough power, the powered device (i.e. single-board computer) may malfunction or not function at all until the power condition is corrected.

Warranty is valid for two weeks, starting upon date of receipt.
