My phone is experiencing interference while charging from the USB-A port Follow

The high power output and pure sinewave of the AC inverter can create some electrical interference. You might experience this on USB-A devices while simultaneously outputting from the AC Output. To avoid this, we recommend not charging sensitive equipment from the USB-A port while also using the AC outlet. After extensive testing, we have not found any negative impact on devices, but you might experience some phantom touches on smartphones, or malfunctioning behavior on other USB-A devices.
