Highly desirable.

Used one time during a bitter cold snap a week ago, car fired right up. Stored charger in clear plastic bag behind driver's seat, left my car unlocked for an hour at McDonald's, someone needed it more than me. Another arctic blast rolling in, no battery maintainer. Keep your car locked all of the time!

Great little charger

This is a great little charger. Wasn't sure what I was getting and if it would work because of the price. But I love it. It's compact and had my Escape up and running in 1/2 hour. And I didn't have to pull the battery out to charge it. I would Highly Recommend.

I ran the battery of my 2019 Suburu out after listening to music with the car off while working on a project in the garage for about 30 mins): dumb i know, but the battery was not fully dead...Lights still came on and car turned over but just clicked. Outdoor temperature was between 55-65 degrees Farenheit. I had Walmart deliver to my house in about 2 hours. Then charged for about 3.5 hours and the car started! Cons: There are some obvious drawbacks, of course this only works if you are home or somewhere with an outlet. Pros: price $23 and delivery $10. Much cheaper than calling for service. Also, the device is very small.
