Thank you for your support to TinyDeal.
We suggest you change to another cable and the charger to charge for it first. By this way you could know whether it is the problem of the cable or the charger or the tablet itself.
And you could also find a tiny button on the side of the item to reset it if there is some defection.
Any other questions please feel free to contact us on https://help.tinydeal.com/contact-us. And we would answer you within 24 hours.
Have a nice day!
