The isignia 4 port USB charger is a great charger if you have multiple devices to charge at once. It provices a decent amount of wattage given its compact size and light weight. Seriously, this thing is only slightly larger (and even a little lighter) than my Anker 2 port 2.4A charger, and this is a 4 port 3.6A charger. Thats pretty good! Build quality seems like it is a little less than the Anker, but I appreciate the size and weight for when I want to toss it in a bag. I brought this charger to europe for a few weeks and it worked really well to charge my iphone, apple watch, as well as my GF's iphone and apple watch all at the same time. It worked really well for that, and you don't need a voltage converter because the charger takes 100-240V input. Overall, I would seriously reccomend this charger especially given the price.
