Samsung Galaxy A6 10.1 charger

Got this new tablet for Christmas and went to charge it in my Truck with my usual Dual usb charger! But I'm getting a red cross on the battery and it says "slow charging". The charger is a Blekin dual usb charger output 1- 1:5v/2.1A out put 2- 2.5v/2.1A. I thought it was going to be fine but can someone recommend me a dual usb charger in the UK please?
