Can the battery charger jump start my vehicle when connected to a dead battery?

Answer:

Unfortunately, it cannot. The HULKMAN Sigma product is a battery charger, not a jump starter.

Difference between a battery charger and a jump starter:

1) A battery charger is a device that recharges your car battery by delivering a steady flow of current and requires time to do so. The Sigma 1 battery charger can maintain your battery and make sure your battery has enough power to start your vehicle.

2) A jump starter delivers an instant power, which is supposed to kick-start a dead battery.

Conclusion: 

The Alpha jump starter is for emergencies, while the Sigma battery chargers can prevent emergencies from coming your way. If you are facing trouble with starting your car and are looking for a more convenient solution, the HULKMAN Alpha jump starter might be a better choice.
