Review on 🔌 Convenient ELEGRP Receptacle Charger for Samsung Android Devices by Victor Anderson

Basically a really great product but if you have excellent hearing you will hear a high pitched squeak when power is applied to the USB ports at around 17kHz. This would be subtle in a busy office or somewhere with background noise, but distracting in a quiet room or bedroom. The design is nice but with only one set of posts for hot and neutral you will need a pigtail if you have other sockets in the series.
