Some older devices don't supply enough power. If you have one of these you can use the car battery to supply the power,etc.
This is sort of funny to ask after my previous message earlier, I knew that v4.3 (my current tablet) would not work. I ran out and just baught a Samsung tab 3 7" with v4.1.2. The hotwire is not powering up. I saw the connectivity issue covered on the tekin website after the fact..... here it comes... will the fix come out in the next couple of weeks? Or should I return this tablet and get another?
