Review on NTONPOWER 15-Foot Long Extension Cord Power Strip with USB and Donut Power Strip Flat Plug - 3 Outlet 3 USB Desktop Charging Station with Power Button, ETL Listed - Ideal for Home Office, Nightstand, and More - White by Elizabeth French

I bought it for traveling because there is never enough electricity or USB outlets at home, hotel or especially airport! This was very helpful on my Thanksgiving return trip when my plane was delayed 3 times and I'd used up my spare battery (20,000mAh) to get updates and keep my friends up to date (and read books too, yes). The small size was perfect for my carry-on. in a clear hard plastic box with a spare battery, USB cable, and other odds and ends that might be intimidating to a TSA agent. It became easy for me to keep everything together and it was easy for them to check the contents.
