Stout Fast New flat plug AC 80-300V Voltage Panel Power Line Volt Test Monitor Gauge Meter AC 110V 220V Digital LCD Voltmeter

Like to plug this into our travel trailer outlets so when we have power, I will know what the voltage is. Also works somewhat for a night light. Easy to read. Not sure about Direct sunlight shining on it though. New, so do not know about longetivity. Have to update review if anything happens.
