Red cord too short for a semi truck

Just got the box the day after Christmas and took it to the truck to try and jump the battery. I charged this thing up to 100% and took it to the truck and it didn't start the truck. It might be because the truck has been sitting for 4 months now and it's snowing 🌨 like crazy outside. Also, I drive a Freightliner Cascadia and the batteries are tucked in the truck behind the staircase and the red cable cord is way too short for it to fit properly. I thought maybe the cords pull themselves out but it doesn't. In order for me to get it to work I had to turn the battery pack backwards just to get it to fit. I'm going to try one more time to see if it will work, if not I'll be sending this back. 700 bucks is a lot of money for this not to work. Carlbro needs to let the cables be retractable. Read more

Solid unit so far.

Works as it should, fired up a Peterbilt. The connectors are a bit too short, especially with large trucks or equipment. Will update in 6 mo or so. Read more
