Terrific gadgets, I have one in each vehicle. Never go anywhere without one, and bring them into the house overnight during extreme cold weather.Next week will be in the single digit temps during the day and negative temperatures at night. I'm going to carry my new portable jump charger with me.
Conditions here are almost identical to yours...except the temp is 28F degrees colder...with an additional 10F windchill drop...and there is no rain, just the white stuff...and, sadly, I know exactly what it is...We have a mix of rain and some kind of white stuff falling from the sky, not sure what it is.
