Power to go

The B&W energy.case is the power outlet for on the go.

The B&W energy.case is a simple, mobile power supply for the professional market. Whether 230 Volt – as if from a socket – or 24 Volt direct current: our energy.cases always supply the right energy. energy.cases are developed for the toughest requirements, are temperature resistant and waterproof.

The compact and emission-free power supplies can be charged with a power supply unit, a car charging cable or a solar cell and are just as suitable for stationary continuous operation as for changing mobile applications. Mobile energy, where it is needed.

We use the energy.case for disaster control operations, for larger water rescue operations and for medical service to supply power to our facilities (accident assistance centre, command centre, etc.) and to maintain the charge of our emergency vehicles during operations where they stand for a long time without being moved (provision for forest fire operations) when no external power supply is available. A great advantage of the energy.case is its great flexibility in charging the battery, it can be charged via the normal mains, via the on-board power supply of vehicles and boats and via solar cells. In addition, its waterproofness and robustness is a great advantage.

DefPower.case Heavy Duty

The powerful Plug & Protect power plant in a case.

The DefPower.case Heavy Duty is the first mobile fuel cell and solar power plant in a wheeled case that is powered by 5 different power sources and can handle everything from complete self-sufficiency to a mobile lorry charging socket that may be needed during field operations. Silent. Remotely controllable. Weather-independent. And with an amazingly optimised heat signature.

DefPower.case Heavy Duty


The latest generation lithium iron phosphate battery has a capacity of 2,000 Wh. This can be charged e.g. via the solar system with two foldable and break-proof solar cells. In addition, the fuel cell extracts 11,000 Wh of usable energy from the for example 10-litre methanol canister. This gives the system a total capacity of 13,000 Wh. The methanol can be refilled at any time or replaced by a larger tank.


Six times longer service life of the latest generation of lithium iron phosphate batteries (LiFePO4) compared to the lithium batteries normally used. This generation of batteries is completely explosion-proof and non-toxic. In addition, there are such attractive safety aspects as overload protection, overheating protection, overcharging protection or dry-running protection of the fuel cell.

Remote control

Remote control from a distance of 50 m. With a secure WLAN connection, they can switch the various outputs on or off with the remote control.


All important components such as the fuel cell, battery system with control unit or the converters can be changed and combined or supplemented with components from other DefPower.cases without any tools.


The dimensions of the DefPower.case HD are 845 x 612 x 415 mm (length x width x height). The [PP+] - TULB not only safely houses all important components, but also two foldable solar cells and an external charger. With a weight of approx. 55 kg, the unit can be carried by two people or simply rolled.


In addition to the fuel cell, the DefPower.case HD can be charged via the foldable solar cells stowed in the unit. Via the integrated MPPT (Max Power Point Tracking) system maximises the solar yield so that more energy is actually generated on a smaller solar surface.

Continuous operation

The DefPower.case can operate in the lowest temperatures without freezing as well as in hot environments. Since only distilled water is emitted during operation of the fuel cell, the self-sufficient power plant can also be operated inside vehicles, in containers or in closed rooms.
