One GBX155 jump starter, booster clamps, USB-C cable and storage bag, as listed by the source. The source lists compatible 12V vehicles with engines up to 10.0L gasoline or 8.0L diesel. Check your vehicle and jump-starter instructions. Keep one kit in each of two vehicles, so you do not need to move a single unit between them. The source describes up to 60W USB-C Power Delivery for compatible devices. Actual power depends on the connected equipment and charge state. No. It is the source-advertised jump-start rating, not a continuous device charging current. Use and store the lithium-ion unit according to its instructions.Frequently Asked Questions
