We have iPods, iPads, iPhones and Samsung S4 phones in the house, plus the odd bluetooth headset or speaker. This device handles any 4 at a time with aplomb. My s4 can display the rate at which it charges and this device rates as high as Samsung's own. iPads charge happily alongside Android brethren. You could get a 4 way socket and 4 chargers to do the same thing but this is so much more compact and elegant, it's size is particularly useful if you are travelling.
