At the heart of the TELWIN CONVERTER 310 USB is advanced PULSE TRONIC technology, which revolutionizes the process of charging and maintaining batteries. It’s not a simple delivery of electricity. It’s an intelligent, 8-phase process that begins with a detailed analysis of the battery’s condition, identifying its type, degree of charge and possible problems such as sulfation.

Subsequent phases include: DESULPHATION (pulse desulfurization, restoring capacity to older batteries), BULK (fast charging with maximum current to about 80% capacity), ABSORPTION (charging with decreasing current to full charge, minimizing gassing), ANALYSE (charge maintenance test, verifying the condition of the battery). The whole process ends with the FLOAT or PULSE (maintenance) phase, which keeps the battery in a state of perfect charge for a long time, compensating for self-discharge. For the professional, this means maximum efficiency, safety and a significant extension of battery life, which translates into real savings and fleet reliability.

The TELWIN CONVERTER 310 USB is designed for maximum safety for both the user and the vehicle being operated. Built-in, multi-level protection systems are standard on Telwin professional equipment. The Safe Start system protects sensitive on-board electronics (ECU, sensors, multimedia systems) from voltage and current spikes that can occur when connecting clamps or during the start-up or heavy charging process.

The device is fully protected against: reverse polarity (prevents operation if the clamps are connected incorrectly), short circuit (automatically interrupts operation if the clamps are shorted), overload (protects the charger’s internal components) and sparking when connected to the battery. For the mechanic or fleet operator, this means peace of mind – even in a dynamic workshop environment, the risk of a costly failure of the vehicle’s electronics or damage to the device itself is minimized.

TELWIN CONVERTER 310 USB is much more than just a charger and booster. Thanks to the SUPPLY function, the device can work as a stabilized DC power source. This is an invaluable aid when replacing the battery in modern vehicles, where voltage backup in the system prevents the loss of data from the on-board computer, radio settings, seats or navigation systems. It eliminates the need to reconfigure and adapt systems after battery replacement.

In addition, the SUPPLY function is ideal for powering the vehicle during diagnostic work, programming controls or presenting the vehicle at the dealership, providing stable voltage without stressing the battery. Complementing the versatility is a powerful USB port (e.g., 5V/2.1A) that allows you to charge smartphones, tablets, inspection lights and other mobile devices. This practical solution makes the CONVERTER 310 USB a truly multifunctional tool for any professional.

The BOOST & GO function of the TELWIN CONVERTER 310 USB is a guarantee of immediate response when every second counts. The device delivers a powerful boost of starting current (up to 310A), capable of starting gasoline and diesel engines in a wide range of vehicles, from cars to light trucks and agricultural machinery, both with 12V and 24V installations. Importantly, the starting process is controlled to ensure maximum efficiency while maintaining safety for the vehicle’s battery and electronics.

Intelligent management of starting power means that the device adjusts parameters according to current needs, minimizing the risk of damage to battery cells. For professional service, roadside assistance or transport companies, this feature translates into reduced vehicle downtime, increased operability and the ability to respond quickly in emergency situations. Reliable starting, even in harsh weather conditions, is a feature that sets the CONVERTER 310 USB apart from the competition.
