What’s included in the box

You’ll get the jump starter itself plus a handful of accessories meant to make it ready to use and easy to store. Everything is packed to give you immediate functionality and some protection against rough handling.

• The GS300 main jump starter unit
• Smart jumper cables (heavy-duty with protection)
