leagend Redefines the Jump Starter with Permanent Onboard Starting Assistance

Designed to stay onboard, the leagend SuperCap Jump Starter Series uses AI Self-Learning Mode for automatic support and Forced Start Mode for manual control.

FOR SãO PAULO, FL, UNITED STATES, October 21, 2026 /EINPresswire.com/ — Traditional jump starters are typically portable emergency devices used when a vehicle fails to start. The leagend SuperCap Jump Starter Series takes a different approach by bringing starting assistance directly into the vehicle. Designed for permanent onboard installation, the system remains connected to the vehicle’s electrical system, allowing it to replenish stored energy and provide starting assistance when needed.
Building on this onboard design, AI Self-Learning Mode helps manage everyday starting assistance automatically, while Forced Start Mode offers an additional manual option for special situations. Together, these functions transform the conventional jump starter concept into an intelligent onboard starting-assistance system for the global automotive aftermarket.

Permanent Onboard Installation: Changing How Starting Assistance Works
The defining feature of the leagend SuperCap Jump Starter Series is its permanent onboard installation. Instead of being stored separately until an emergency occurs, the system remains connected to the vehicle’s starting battery, making starting assistance available as part of everyday vehicle operation.
Once installed, the system draws available energy from the vehicle’s starting battery to charge its supercapacitors. During engine cranking, the stored energy provides additional starting support, helping reduce the discharge load on the original battery.
After the engine starts, the vehicle’s charging system replenishes electrical energy, allowing the onboard unit to recharge its supercapacitors automatically under suitable operating conditions. This helps prepare the system for subsequent starts without requiring drivers to remove or separately recharge the device.
Supercapacitor technology provides the energy-storage foundation for this design. Unlike conventional portable jump starters that rely on built-in rechargeable batteries, the leagend SuperCap Jump Starter Series uses supercapacitors to store and rapidly release energy. Their high charge-discharge cycle capability supports repeated starting assistance, while the absence of an internal rechargeable battery eliminates the need for routine charging of a separate battery within the device.
The series is also designed to deliver stable, reliable starting assistance across a specified operating temperature range of −40°C to 80°C. From severe winter conditions to high-temperature environments, its wide temperature tolerance supports dependable operation under demanding climatic conditions. Combined with low standby power consumption, these characteristics make the system suitable for long-term onboard use.
The key advantage lies in how permanent installation, supercapacitor energy storage and automatic operation work together. Rather than relying on a separately stored emergency device, drivers have an onboard starting-assistance system that remains connected and can provide support when required.
For automotive aftermarket importers, distributors and wholesalers, this creates a distinct product offering that goes beyond conventional portable jump starters.

AI Self-Learning Mode: Intelligent Management for Everyday Starting
Permanent onboard installation allows the system to remain connected to the vehicle, while AI Self-Learning Mode builds on this foundation by managing starting assistance during everyday use.
Following installation and the initial charge, the system monitors battery voltage and engine cranking behavior during the vehicle’s initial starts. It uses this information to establish a vehicle-specific baseline and recognize the vehicle’s normal starting characteristics.
Based on the learned information and monitored operating conditions, AI Self-Learning Mode helps the system determine when additional starting assistance is needed. The supercapacitors supply the stored energy, while the control system manages its delivery to support engine cranking under appropriate conditions.
During normal operation, drivers continue to start their vehicles as usual. The system works in the background, monitoring starting conditions and automatically providing assistance when required, without the need for manual activation during every routine start.
By combining vehicle-specific learning with intelligent starting management, the system is designed to support everyday vehicle starting rather than function only as an emergency response after a starting failure.
For importers and distributors, AI Self-Learning Mode provides a meaningful technical distinction when introducing the product to dealers and professional customers. Workshops and installers can also demonstrate its automatic operation during installation, product training and customer handover.

Forced Start Mode: Additional Control When Needed
While AI Self-Learning Mode serves as the core of everyday intelligent starting management, Forced Start Mode provides an additional option when direct user intervention is required.
Through the device or Smart App, users can manually initiate starting assistance using energy stored in the supercapacitors, provided sufficient energy is available and the required operating conditions are met.
When the vehicle’s starting battery cannot supply sufficient energy to replenish the supercapacitors, external USB-C charging provides another option. A compatible external power source can be used to recharge the supercapacitors before a starting attempt, where supported by the model.
Forced Start Mode complements rather than replaces the system’s automatic operation. AI Self-Learning Mode supports routine starting management, while Forced Start Mode gives users direct control in specific situations.
For distributors, workshops and professional service providers, these complementary functions offer practical applications for product demonstrations, dealer training and customer education.

Drive Mode and Smart App Monitoring
Beyond engine starting, the leagend SuperCap Jump Starter Series also incorporates Drive Mode and Smart App connectivity, extending the functionality of the onboard system.
When enabled, Drive Mode allows the supercapacitor bank to serve as a short-duration energy buffer while the engine is running, helping respond to brief electrical load fluctuations under supported operating conditions. This function works alongside the vehicle’s original electrical system rather than replacing its battery or charging equipment.
Through the Smart App, users can access vehicle battery voltage, supercapacitor status, device temperature, starting and discharge records, historical information and alerts for unusual conditions.
These features provide greater visibility into the system’s operating status. For workshops, battery specialists and automotive electrical service providers, the available information can also support customer discussions, troubleshooting and related maintenance services.
Together, intelligent starting management, manual activation and connected monitoring extend the product’s functionality beyond that of a conventional portable jump starter.

A Model Range for Different Vehicle Applications
The leagend SuperCap Jump Starter Series includes four models designed for different passenger and commercial vehicle applications.
• leagend JS200 is designed for selected 12V passenger vehicles, including sedans and SUVs.
• leagend JS300 is designed for a broader range of compatible 12V passenger vehicles and SUVs with varying starting requirements.
• leagend JS400 is designed for more demanding 12V starting applications, including selected SUVs and performance vehicles.
• leagend JS600 is designed for suitable 24V commercial vehicle applications, including trucks and buses.
Model selection should take into account vehicle electrical-system voltage, starting requirements and operating conditions. Buyers are encouraged to consult the official product specifications and compatibility guidance to determine the appropriate model for each application.
For importers and distributors, this range provides flexibility to serve different vehicle segments and develop product portfolios suited to their target markets.
