Three weeks ago, I drove my son to get his first Covid shot. A 2 1/2 hour trip turned into 3 1/2 hours for some reason, thanks to Mapquest and GPS. For yesterday's trip, I decided to take the Interstate - longer, but less chance of getting lost. Great trip.

My son was back in the car at 1:00 PM. I pushed the starter button - nothing. Totally dead. I had left the headlights on. Heavy rain on the way there. Since I hadn't opened the car door, it didn't alert me to that situation. I waited a while for the battery to recover, but it didn't recover enough. I have road service with Good Sam - popular with RV owners. I called them, and they said it would be 60 - 70 minutes. Long story short, they mistakenly canceled the order, and no one arrived till 5:00 PM. It took less than a minute to get the car running.

As soon as I got home, I went to YouTube and looked up reviews of battery jumpers. Project Farm did two good reviews, and other reviewed some, as well. I'm torn between the Tacklife ($90) and Autowiz ($130). The Autowiz is not a battery. It's a capacitor. Even if the car battery is down to 5V, it will charge the capacitor in 3 - 10 minutes and start the car. The Tacklife would have to be charged at regular intervals to keep the battery alive.
