Review on Black Power Strip Surge Protector with USB Ports and Flat Plug, Enhanced Overload Surge Protection by Ryan Saxton

Like some other reviewers, I noticed a high level of noise when using the USB charging ports. Maybe some people are not sensitive to such high frequencies? The noise itself is annoying, but what worries me most is how it modulates and flutters depending on what I'm doing on the device. It seems to change its noise a lot, like a drive reading information. I may be paranoid, but whatever is making the noise seems annoying at the very least. All I wanted was a simple power strip for power. I'm tempted to break it open to take a look, but I'm not sure I'd learn anything dubious if I did. Nonetheless. That seems strange.
