Summary: Outdoor power supplies can produce noise during charging, but the level depends on battery type, cooling systems, and environmental conditions. This article explores why noise occurs, compares industry data, and shares practical solutions to minimize disruptions for camp. Why can I hear noises from power supplies? This common phenomenon primarily stems from a physical effect known as coil whine or the piezoelectric effect, where electrical current causes components to vibrate mechanically at an audible frequency. These vibrations, though often minor, can become. . All the parts are brand new, and now I'm wondering that should I RMA the PSU or what? I can send a link with the noise if needed. if it's loud enough to be noticeable in a recording go ahead and upload a sample. It might also mean there's a problem. The issue often starts with the transformer. Understanding Charging Noise in Outdoor Power Stations Outdoor power supplies – whether used for ca. .
