Charging problems

[Amy Rose The Hedgehog]

I guys, I'm having troubles with my iPad charging. I will put it on the charger and set it down gently, then it starts charging and not charging on and off and off it gets a little frustrating after a while, I tried to reboot it didn't work. Then eventually a yellow triangle with a black exclamation mark in the middle pops up and under it it says " this accessory is unable to be charged "
Can anyone help me for why it does this? :/
