text: Try this way if over heating
  
  I hope this sharing helps. When I was using it, it kept stopping charging every 1-2 hours due to over heating. So I put the charger a little higher so the air can flow underneath. (See picture) Then it worked without stopping. I think the floor material affects this problem in some way, but the company need to find a solution for it. Ex. putting legs. Then I will give 5 stars.
