Review on 🔌 High-Performance USB Outlet Extender Surge Protector - Rotating Plug, 6 AC Multi-Plug Outlet and 3 USB Ports (including 1 USB C), 1800 Joules, 3-Sided Swivel Power Strip with Spaced Outlet Splitter - Ideal for Home, Office, and Travel by Adam Jackson

Unfortunately, the product I received was making a high-pitched squeaking sound every time a USB device was plugged into the USB ports, otherwise I'm very satisfied with it was. I already have two other Mifaso power strips/surge protectors but I wanted one that didn't block both outlets. This seemed like a great option and worked great with just regular plugs attached to it. But after I plugged in the USB device, I noticed a high-pitched howl that sounded almost exactly like a neighbor's burglar alarm going off somewhere down the street. When I realized it was actually coming out from under my desk, I thought maybe one of my electronics' power supplies was failing. But when I went there to trace it, I found that it was the same device and that it was only happening with the USB connected. It drove me insane so I had to send it back.
