I purchased this USB charger about a month ago. We wanted to charge our iPad's and iPhones in our loungeroom. This charger is excellent, high capacity charging, charges multiple devices Simultaneously and is very small and neat. It has reduced the Certainly "cable clutter" in our loungeroom as this charger fits neatly under our lounge. There has been Certainly no noise from the charger! We will take it with us When We travel to US. Single charger for multiple devices Will certainly make travel easier and lighter !!
I would highly recommend this USB charger if you are looking to charge multiple devices !!
