Frequently asked questions
How many jumps per charge?
About 20 jumps on a full charge for typical 4-cylinder engines, fewer for larger diesel engines. Recharge via USB-C in about 3 hours.
Will it really jump a diesel?
Yes, up to 5.0L diesel. For larger truck diesels (6.0L plus), step up to the GBX75 or GBX155.
Can I charge my phone with it?
Yes. The USB-C output supports fast charging up to 60W, enough for phones, tablets, and most ultrabook laptops.
