So Monday 12/1/25 I used this item. It was 20 degrees outside. The semi sat for 3 days and of course these batteries are now going bad. I pushed the button and the item is only at 50% charged. Still I connected it to my 4 battery in series. IT WORKED LIKE A CHARM.!! Without a hiccup. My Freightliner started right up. Truly impressed.👍 🔴UPDATE: 12/13/25 What I said above still stands. The problem is now that this unit only give about 5 to 8 jumps depending on the severity of the weather. And it was 🥶 COLD. 1 below zero to be exact. Easy to use VERY POWERFUL Good quality Read more
