Multi-Use Travel Dock Both Charges Mobile Devices and Transmits 4K Video

Plug it into any NEMA 1-15R, NEMA 5-15R or NEMA 5-15/20R AC outlet to ensure your laptop, tablet, smartphone or handheld game console charges at its fastest possible speed. Connected devices are protected from over-current, over-voltage, over-temperature and short circuit.
