How It Works

The JS200 uses supercapacitors to collect and store electrical energy before rapidly releasing it to provide additional starting power.

When the vehicle battery is too weak to crank the engine normally, the unit can recharge its supercapacitors from the remaining battery energy or through a compatible external Type-C power source before providing starting assistance.

Charging Options

• Recharge from compatible vehicle battery
• Approximate vehicle-battery charging time: 3–22 minutes
• Type-C charging: 5V/2A

Actual charging time varies depending on the battery condition, available voltage and operating environment.

Package Includes
