The DTech 55–in-1 Bluetooth Card Reader & Hub. Sorry, I refuse to believe that we live in a world with 55 memory card formats. Nope, don’t care what you say. Not listening. Talk to the hand. Anyhoo, this puppy comes with a Bluetooth dongle so you can connect your BT devices to your computer, as well as a pretty measly 2 USB ports. As someone who currently has two – count ‘em – 7 port USB hubs in full time occupation, this is not going to fly, but YMMV. $29.00.
It is not only a common card reader, but also a Bluetooth dongle and USB 2.0 hub at the same time. You can interact with Bluetooth devices by its Bluetooth function and its 7 memory card slots which can read and write different memory cards. You can connect any other USB devices with the 2-port hub…Actually, there are 2 ports for connecting devices with the computer for data transfer, the remaining port provides power for devices. It is good for connecting USB lamps, USB fans, USB Ionizers, etc
