4 marine engines !!!
2 of 2 found this helpful I bought the GB30 and charged it on an office computer USB cable. I then stored it on my boat. I spent an entire day out on an anchored boat in the summer on local waters. I went to start my two jet drive engines on my boat and got zero output from the battery as a result of playing my high wattage stereo all day long. I told my wife this is a perfect test for this unit!! Surprisingly it started both the engines (one at a time of course) within 10 seconds. After idling for 5 minutes I was approached by another boat owner with 2 dead batteries on his boat and two much larger engines (8 cylinders each). He ask for a jump start and wanted to push the 2 boats together to jump start his with his 20 some foot long jumper cables. Instead I walked over to his boat with the GB30 and told him we'd try this. He laughed the entire time. He went under his deck ( 8 people aboard) with the unit and attached and started both engines one at a time with this unit. When he came from below the deck, he was laughing and saying "I don't know what the hell this is but I'll guarentee you that I'll own one by next weekend" I now put this unit in my truck in the winter when we aren't boating.

Great product but it's pricey. Not worth what I paid.
