Review on 🔌 KOOPER Multi Plug Outlet Extender with 3 Outlet Splitter, 3 USB Charger 3.0A - Wide Spaced Cube Plug Extender Outlet Adapter for Kitchen, Bathroom, Dorm, Office, Cruise Ship, and Travel - Essential by Robert Aan

Multiple socket extension, KOOPER wall plug with 3-way splitter 3 USB 3.0A charger Large cube plug Socket extender Kitchen adapter Bathroom Dorm Essentials Office Cruise Ship Travel (ASIN: B09BKWW46J ) ✅ High quality plastic ✅ Rounded corners ✅ Price ❌ USB charging whistle UPDATE: When I use the USB ports to charge, I hear a howling sound. This is due to the pulse width modulation of the current that converts AC to DC and poor or no noise reduction. It's not a problem, but it's annoying. One star for that. However, at $9.00 this is still a good fork. -------- The socket extension from Kooper worked great for me, except for the whining USB charging port. All sockets worked, including USB.
