Mobile power storage with charging power
Energy exactly where you need it – with Fleetboost’s mobile battery buffer storage systems with charging infrastructure – independent of the power grid. The demand for powerful, mobile power supply solutions is growing – whether on construction sites, in transport logistics, or at events. Fleetboosters are mobile battery buffer storage units that enable an intelligent and flexible charging infrastructure with a strong, limited grid connection or even without a fixed grid connection. As plug-and-play systems, they reliably deliver energy exactly where it's needed – quickly, scalably, and regardless of location.
Boosted grid
Charging via CEE connection or ultra-fast charging infrastructure – even in weak grid conditions. The Fleetbooster flexibly supplements limited connection capacities in low voltage, medium voltage, or completely off-grid.
Performance up, price down
Take advantage of price differences on external electricity exchanges: Charge your Fleetbooster when electricity is particularly cheap. Balance peak loads and increase the cost-effectiveness of your charging infrastructure.
Super-fast loading & unloading
Ultrafast charging at 400 kW via liquid-cooled cables significantly reduces downtime. Powerlock connectors enable battery charging or discharging at up to 800 kW – flexible and powerful.
Flexibly scalable
The mobile systems can be deployed anywhere and quickly relocated as needed. This means your charging infrastructure remains flexible at all times and can grow with your needs.
Future-proof investment
Thanks to state-of-the-art LFP batteries from CATL with high cycle stability, Fleetboosters meet the highest quality standards. Fast after-sales support and an optional 10-year warranty protect your investment for the long term.

About Us
Energy. Simple. Everywhere.
We believe that the mobility transition will only succeed if energy is as flexible as the people and companies that use it. The electrification of transport, construction, events, and agriculture requires more than good intentions – it requires an infrastructure that thinks ahead, adapts, and isn't held back by bureaucracy.
Fleetboost was born out of practical experience and we know first-hand the challenges associated with charging infrastructure. And we know that they look different everywhere - on the construction site, in the depot, at a festival in the middle of the city.
That's precisely why we develop solutions that are mobile, scalable, and affordable. Our Fleetboosters ensure predictable energy costs, flexible deployments, and true independence from the grid – with a product that sets standards in quality, performance, and service.
Our mission: To deliver energy where it's needed. Simply. Fast. Without detours.
