Review on 💡 Schumacher 15 Amp Power Converter: Effortlessly Converts AC Travel Products to DC Power by David Roberts

to easily set up maps on a Garmin product. Device connected, everything works and looks great. The device had a touchscreen and I had a hard time getting it to work properly. I tried to calibrate my Garmin device but it didn't work. I was about to call Garmin service but figured I should at least try the device in the car. Connected and everything works fine, there are no problems with the touch screen. Again at Schumacher with the same result and I printed out a return label. Thank you Revan There must be some voltage difference between the car's 12V plug and this unit, or I could just get a bad one. Too bad this is exactly what I needed to program inside.
