This thing is fantastic. I have a diesel moterhome the batteries went bad and I started and drove on this battery pack to get them replaced,about 8 miles. That saved me and it wasn’t the only time I had a car without a battery in it that I needed to take and ?????? worked on, just connected it to the cables and drove it across town 10 miles. Once I was working at an equipment auction and needed to jump start several pieces of equipment some gas other diesel not a problem. I take with us when we go camping as a power supply and charger for all the small stuff ( lights phones radios ) always comes threw. And once charged it stays that way due months in the truck. LOVE IT.

Great charge
Amazing. Jumped my totally dead battery with ease. And still had plenty of power. Says to recharge every month, but it's more like 2-3 months. Really powerful for size. Peace of mind.
