This morning my step son's civic wouldn't start and needed a jump. I'm so used to the procedure I half awake went for my jumper cables and my car. Then I slapped myself to wake up and stared at my I-Pace puzzled. 1. Where is the 12v battery? 2. Can I jump a petro car?

I quickly find the 12v battery, pics below, but questioned if there would be enough juice to jump the Civic. Lucky my neighbor was heading to work and had a battery charger so we jumped it with that no problem.

I started to Google info on the ability to use an electric car's 12v battery to jump a petro car and it seems the consensus are no there is not enough juice.

Anyone have any experience using an electric car to jump a gas car?

Don't know about the I Pace but it is highly not advisable in most BEVs. The 12V battery is not supplied by an alternator, and some BEVs will use a much smaller capacity 12V to begin with. When you are jumping a car with an ICE you run the engine and rev a little for the alternator to help/supply the current. In a BEV an inverter will recharge the 12V from the main traction battery on demand, but is usually NOT designed for the load needed to jump a car. In fact you may cause damage from inadvertent surges, etc.

I suggest using a portable charged jump start box like this:
