You have charging cable. With most USB strip / USB multiport charging cables, you simply cannot charge more than 2 new devices at the same time. This is a simple reason for power consumption, most newer devices require 2.4 amps or more to charge, but your outlet can deliver at most 10-15 amps (in most cases). I was shocked when I connected everything to this gem today and today I was able to charge 2 tablets AND 2 new phones. Of course, the circuit I used was designed to charge our devices, but the fact that you can use it to FAST charge 4 devices at once is phenomenal. I'm about to buy another one. By the way. I do not participate in this company evaluation program. I didn't get anything for free or at a discount. No fake reviews here, it's just amazing!
