Hi all I have the Teclast keyboard and I find it to be OK the usb ports recognise everything I plug into them. When charging the main bright blue led is illuminated and when unpluged the three dimmer led’s to the right indicate how much power is remaining in the keyboards battery if the button on the side is pressed . The plus with the keyboard is it will extend the tablets battery life by approx 3 hours if viewing videos etc. The downside is that the tablet will use up the keyboards battery in preference to the tablets batteries which leaves the keyboard unresponsive once the batteries are flat. The keyboard is great as a desk based charging port and if required as a portable device for longer than the three to four hour keyboard battery life just put a small piece of sellotape over the two middle pins on the pogo conection on the tablet and the keyboard battery will last for numerous days. The usb ports will power and run portable drives but will not charge devices such as mobile phones.
Ken.
