I just purchased this jump starter thank you for your video. I saw the 4000 for 50% off so l went for it to jump start my 2006 Solstice. I think l have a phantom drain but it may be due to me letting it sit for months without running it. I want to take it to a mechanic about 3 miles from my home l figure The jump starter will power me up if it shuts off…wish me Luck. PS Do you still use your Yarber?
