Hello there, Thank you very much for buying our In wall 3.6A Surge Protector USB Hub. Regarding your inquiries I wanted to let you know this device provides up to 2.4A per USB port and the surge protection is placed between the power input to the outlet and the AC-DC power supply. It works just like plugging a USB charger into a surge protector. We want you to fully enjoy this and other Insignia products. Arely R. - Insignia Support.
