Most chargers supplied have a USB port, are rather bulky and take sometimes two at once taken by the arrangement of the jacks on your power strip.
In this case, this charger is perfect for you! It is practical: Instead of connecting directly to the plug, the plug is connected via a cable which allows to have it on a piece of furniture, not at ground level without using an extension cord.
It loads quickly gadgets! My tablet is yet greedy, needing to 2.1A to charge at full speed by the manufacturer. It loads at the same speed on the charger into the USB charger supplied with the tablet which is a pleasant surprise.
Unlike other chargers that promise 2.1A load but actually divide this value with the port number used.
Here Anker 40W charger supplied 8 amps, averaging 1.6 amps by USB (much more than the 500mA minimum recommended by the standard) but in practice automatically adjusts the current value for each USB port through PowerIQ technology: If you have two bars, two telephones connected headset and then each device will receive the maximum current recommended by the manufacturer. And there's the margin! If you have two bars, two telephones and a bluetooth headset, you can connect all the devices together and they will be loaded at the maximum speed. Another plus: it is compatible with all electrical standards around the world, subject to having the adapter or cable to connect the aproprié.
Fast, Design, Practical and cheap, this is my favorite USB charger.
