Review on 💻 High-performance Black Aluminum Notebook Docking Station with Cooling Fan - Silverstone NB02B by Ricky Habbani

The label below clearly says 12 volts and the internal fan is marked 12 volts, but the external power connector is only rated for 5 volts and is unmarked. 12 volts burn the card. When the fan is running on the nominal 12 volts, it runs much faster, but the cheap plastic case amplifies the fan's vibration and makes a lot of noise. When the fan is powered by your laptop's USB port, it runs so slowly that it's of little use. There are many laptop coolers at Revain that cost less and cool your computer better. Do not buy this overpriced item.
