How do I make my Irulu keyboard\case to comunicate with my tablet besides plugging it's mini usb cable into the side of the tablet?

normally keyboards like this may use bluetooth or USB connection to work if USB you can buy a USB-OTG cable to use the keyboard

first of all, make sure that your tablet has an On the go USB port or data port if not, it can only be used to charge. If you connect our tablet to a computer usb port, and your computer recognises it, then you have a data port.

If you plug in a usb memory stick, and your computer can not read it, it does not have a USB to go port.
Also, some Cable adapters are On the Go wired, and may not work properly.
It may also be that the USB port is not providing enough power from the tablet to the keyboard. In that case, buy a split power usb cable, and plug the red (power only) into a usb charger or powered usb hub.

Might consider going to the iRulu site (irulu.com) and asking the folks there. It might be in the user manual which can be downloaded from https://www.irulu.com/download-center-new

Juello. Did some research on your tablet at Amazon, (http://amzn.to/1xWx6S5) and see that they also have an AC charger (AC charger adapter with a 3.5mm power jack and delivering 5VDC 2A). Available for $5: iRulu Black AC Home Wall Adapter Cable Charger for Tablet PC 5V 2000mAh or a there's a nice replacement KB and cover: iRulu New Portable 10 1 10 5 Android Tablet USB Keyboard Case Black . I would guess the connector snapped off inside the tablet, so you will have to remove it with some tweezers. If the pin for the AC adapter broke off inside the tablet, that's a problem, but most everything can be charged from the USB port too see this website:

Not sure on you particular model but most tablets have 2 mini USB ports one has a power supply and the other is just an I.O port .

Try your keyboard in the other port if you have one and it should work. If not it may be faulty.

Fnd your user guide / manual for your exact tablet and read instructions for the cable.

Your tablet is not built to accept usb keyboards.

am trying to connect with internet my device (irulu ak 305) but it didn't connect

I got my tablet with a charger but after some time it got damaged.. NOW I USE THE MINI-USB cable to charge it.. you can use an adaptor like the one that comes with the Samsung galaxy cellphone and use the mini usb cable with it.. Hope you understand my mess.. good look..

Where can I find irulu tablet's kiboard user manual
