RAVPower or Anker Car Charger

Thanks, I just bought a Belkin, and wish I had bought a Blitzwolf. Your tests are great and make the difference in what many of us choose.

Edit: HKJ, Please excuse my ignorance, but using the Aukey CC-T1 30W Dual Port Car Charger with Quick Charge 2.0 Dual-Port Is there any reason I could not use both or either USB port to charge a tablet? I am not sure why there are two different ports??
Thanks,
Jerry
