I bought a cheap dual usb wall charger from eBay to charge a iPad and samsung s6 at once but it seems to take 6> hours to charge. I've checked the specs on it and it says 2.4A ? Can any recommend a dual charger that actually works in charging at the same rate ? I've now been looking at branded chargers such as anker. What am after is a charger between 2-4 ports, compact in size and something that plugs straight into the wall socket. Also this is to be used as my travel charger which i will be using a plug converter plug from UK to Europe. The plug converter says its a 10A.
