01. Durability of car battery and prevention of battery discharge

When using the black box, the car battery is not used, which prolongs the life of the battery. 

When a car battery is discharged once, its capacity drops by more than half and discharge may occur continuously. 

02. Improved fuel efficiency and easy installation 

Running the black box with an auxiliary battery helps improve fuel efficiency, and the installation method is simple, so anyone can easily install it.  

03. Built-in highly efficient self-developed smart charging circuit

The vehicle and battery are safely protected by a smart charging circuit developed in-house with protection functions such as overcharge, overvoltage, overcurrent, and short circuit. 

GSP Battery's patented technology is equipped with a function to prevent reverse voltage and reverse current. 

04. Controllable from smartphone through mobile Bluetooth connection

GSP Smart Slim Pro can be used as a mobile app through Bluetooth linkage to check remaining power (power consumption, current usage, charging current, SOC value), etc.

You can use it smartly by selecting the charging cut-off function at low and high temperatures and operating it on the mobile app.
