So I did not think I would see 5 pages on jump starting a car... But I'll add one more post.
I would recommend the NOCO Boost Plus GB40. Just bought is for myself and son for Christmas. I've used it twice this past week. Once on my snowmobile, which was my fault. Check the mileage when filling it up with gas before a 7 hr trip and left it on in the trailer. When I got were I was going I realized the battery was dead. Then the other day my son calls and said his battery light came on his dash. (2011 RAM) He came home I check it with a voltmeter and it pointed to the alternator. (Previous owner just had the alternator, belt and battery changed in Aug of 2022. (It was a MOPAR Remanufactured) Drove to the autoparts store to double check, and yep it's the alternator. They were out at that store so had to run up the street 10 miles. I roll the dice if we should go home a get my truck or chance it with his truck and save 20 minutes. Well as coming home more lights came on we made it in a parking lot 3 miles from our house. Pulled out the GB40 hooked it up and secured it to the battey. It was just enough power to get us home so I did not have to change the alternator in the cold.
Yes, I know that not the way it designed to be used but it worked and did what I needed. My point it is it gives options.
Here is a funny story, and the only other time I've need a jump. I had to get it from an Amish guy. I was have and air conditioner installed in a trailer a few years ago. You may or may not know RV's and trailers are made around Elkhart, IN. I found a deal on a AC unit in Shipshewana, IN and called the place set up an appointment with the guy for 7am on a Saturday. I said hey I see on google maps you have a big parking lot would you mind if I stayed Friday night in your lot. He tells me no problem but the highway is a bit noisy... (That was the first red flag.) Shipshewana is known for being Amish. So drive over there after work on Friday and get set up, grab some dinner and I'm in bed by 10pm... Now I think it got dark at that time around 8pm. So I had the trailer lights on running off my truck battery for a few hours. They are all LED and I done this before and never had an issue. As I go to bed I have the trailer windows open and I thinking it's really quite out here for just being off a State Road. I then wake up multiple times to the sound of horses up and down that same state road between 12 and 3 AM. Get up at 6AM. Looking at Google maps beforehand I knew this guy's business was at his house. So I figured I be ready early for the guy. I come out of my trailer and setup a folding chair and sit and watch the family tend to the horse, other animals and start doing daily chores... Well 7:30 comes around and no one has come down by me or the barn where the business is out of. Since I pulled in at evening time I did not pay attention to the business sign just sitting leaned up against the building. Being after my appointment I call the guy to make sure everything was still good.
He answered and said:
Him: Yep, I've been here waiting since 7.
Me: Well where are you?
Him: Standing in my empty parking lot.
Me: What! Where am I at.
Him: Not sure, did I give you the new address or did you use google maps.
Me: ahhh Google maps, remember we talked about me staying the night.
Him: Oh yeah, I forgot to give you my new address, I'm right down the road...
Me: Ok be there in 10 mins (Thinking new address? That is a minor detail that was left out!)
Feeling terrible and like some weirdo that I just stayed on someone else property, I put the chair in the trailer go to start the truck and it just does a slow crank... but turn over. I thought that was odd. I must have had the lights on to long last night... but figure it would charge back up driving it. I pull up by the house and apologize. The owner said it's happen two other times and he figure I was having something done to the trailer. He planned on coming down and talking to me in a little bit but did not want to wake me to early. He was very nice and understanding.
Then I made it to the correct place I shut off the truck and the guy installed the AC unit in about 30 mins... He used a forklift to put the AC unit on top of the trailer. made the connections and he was done. Pay him and go to start my truck and nothing. I look around and I'm like this is not good. Where am I going to get someone to jump me around here. I ask him if his forklift could jump me, He said the battery was to small. But no problem he had a skid steer he would go get. Sure enough he did and that is how I had an Amish guy jump start my truck.
