The TELWIN DYNAMIC 620 START is designed to deliver impressive starting power exactly when you need it. With a maximum starting current of up to 570A, it can “revive” even severely discharged batteries in large diesel engines that often challenge weaker models. Whether you’re working with trucks, buses, agricultural machinery or construction equipment, the DYNAMIC 620 START provides a sure and fast start.

The key to this performance is a high-quality transformer and properly selected components that can withstand high current loads. The start-up function is immediately available and easy to use, minimizing the time required for intervention. For the professional, this means less downtime, greater work efficiency and the ability to service a wide range of vehicles without the need for many different starting devices.

DYNAMIC 620 START is not only a powerful booster, but also a versatile charger for lead-acid batteries (WET/START-STOP). The ability to select a charging voltage of 12V or 24V makes it a versatile tool for workshops servicing cars, motorcycles (with larger batteries), as well as trucks or industrial machinery. What’s more, the four-stage charging current regulation (up to 70A average current according to EN, 90A effective current) allows you to precisely adjust the charging parameters to the capacity and condition of the battery (from 20Ah up to 1550Ah).

This flexibility ensures optimal and safe charging, protecting the battery from overcharging and extending its life. The professional will appreciate the ability to effectively manage the charging process for a diverse fleet of vehicles, resulting in better battery maintenance and reduced costs associated with premature battery replacement. An easy-to-read ammeter allows you to monitor charging progress in real time.

The TELWIN brand has been synonymous with quality and reliability for years, and the DYNAMIC 620 START model fully confirms this. The device is equipped with a number of key safety features that protect both the user, the charger and the vehicle being operated. Overload protection prevents damage to internal components in the event of excessive current draw. Polarity-swap protection eliminates the risk of serious failures caused by accidental misconnection of battery clamps. In addition, terminal short-circuit protection protects the device in the event of accidental contact between the clamps.

Robust metal housing and high-quality components guarantee a long service life of the device, even with intensive use in a demanding workshop environment. For the professional, this means an investment in equipment that will not fail at a crucial moment and will serve without fail for many years, ensuring continuity of work and safety of operations.

Despite its power and rugged construction, the TELWIN DYNAMIC 620 START is designed for ease of use and mobility. Equipped with large, sturdy wheels and an ergonomic transport handle, the unit can be moved effortlessly around the workshop, yard or even in the field, wherever it is needed at the moment. This is key to maintaining work efficiency, especially in large facilities or when handling multiple vehicles.

The control panel is simple and intuitive. Clearly marked switches allow quick selection of the operating mode (charging or starting), voltage (12V or 24V) and one of four charging current levels. A large analog ammeter provides clear information about the current, allowing real-time monitoring of the process. As a result, even a less experienced operator will quickly master the operation of the device, and a professional will appreciate the time savings and convenience.
