The GYSCAP 12 V DC/DC is an independent jump starter without an internal battery. Its supercapacitors provide high output power, ensuring starts (1600 A at 1 V/C). It is maintenance-free. The integrated DC/DC converter allows for rapid charging via the battery of the disabled vehicle and then automatically from the started vehicle to enable further starts.

1. Charge a 12 V battery (maximum 2 minutes 30 seconds) without a power supply or outlet. The GYSCAP features an integrated DC/DC converter that can charge supercapacitors with up to 50 A from the low residual voltage of a discharged battery. Once the engine is started, it also ensures complete automatic charging via the alternator.

2. Charge at the vehicle's cigarette lighter (maximum 4 to 9 minutes) while driving to the location.

3. Charge with a Gysflash 4.12 or 12.12 (maximum 8 to 15 minutes, depending on the model) from the power grid.

The integrated DC/DC converter optimally manages the charging of the supercapacitors while maintaining the functionality of the vehicle's electrical system.

• It monitors the voltage of the vehicle battery and adjusts the charging to prevent a voltage drop below 8 V, thus protecting the battery and the data of the vehicle's control units.
• It regulates the power used to charge the supercapacitors (maximum 50 A) to protect the alternator from overload without affecting the charging time of the supercapacitors.
• Always ready for use, thanks to quick charging.
• Unlimited starts: Start the vehicle and let the booster charge while the engine is running, then continue with as many vehicles as you wish to start.
• Maintenance-free: Does not need to be charged when not in use.
• Constantly ready for use even after years of storage.
