A:Answer Red blinking light during charge is a result of using a Non-Fast charge power source. I have a Samsung galaxy S8+... When using the wall tap (fast charger) that came with my phone to power the Insignia wireless charger, the light is blue while charging and the phone charges quickly. When using a cheap wall tap that I got from the dollar store, it flashes red while charging and takes about twice as long to charge the phone.
