In our range you will find cost-effective chargers in conventional 50 Hz technology and state-of-the-art high-performance devices with inverter technology which convince by their small size and high efficiency. We give you advice especially on your application and select the suitable charging system for you by taking into account all economic aspects. In addition, we are able to design chargers for your specific application.

Charge Cube - the compact, efficient lead-starter-battery charging device


The Charge Cube is a compact high-frequency battery charger, which is designed as a broadband network input device. It corresponds to the highest efficiency class with a power factor of 0.99 for energy-saving Operation and can be operated worldwide without national variations in all power grids. Country-specific versions are not necessary.

The charger offers you an automatic IU characteristic curve for batteries with liquid and bounded electrolyte as well as for lithium-ion batteries. It is suitable for batteries of 3 to 300 Ah (adjustable via capacity selection). The Charge Cube has an automatic detection of vehicle voltage and a cooling using temperature-regulated fan.

It has a self-explaining and user-friendly menu guidance by using a color display and also uses pluggable mains and charging cables for an easy handling. The charger is designed with a robust steel housing with soft rubber edge protection to avoid vehicle damage.

The Charge Cube is a robust and high-efficiant battery charger, which has been designed epecially for hardest working conditions in workshops. Thanks to the update-capable firmware the charger offers the highest-possible operational safety even for future battery generations and changing requirements on quality assurance.
