The engine circuit has an electric pump and a mechanical pump, the intercooler circuit only has an electric pump. Both pumps can be activated with a specific sequence of buttons/pedal in the car, so if you're doing that with the car off then a charger is recommended.

I did it without a charger and didn't have any issues. Even if the battery does die or the car cuts off, it just turns off the pump. Not really dangerous.
