With the EFOY fuel cell, you always have your own compact power generator with you and are completely independent of the power grid. The EFOY charges all common 12 or 24 V battery types fully automatically, reliably, quietly and in an environmentally friendly manner. Whether in the mobile home, on the boat or in the (garden) hut, you decide where the EFOY is used.

Lots of power in a small space.

With a weight of only approx. 6 kg and a height of 27.5 cm, the EFOY is a real space saver. Thanks to its compact design, the EFOY can be installed anywhere to save space.

Compact and light

Fully automatic and maintenance-free

Environmentally friendly and quiet

Power in all weathers

No more sweating in the sun, now you can stand in the shade. Even in bad weather, at night or in winter - the EFOY fuel cell, in contrast to the solar panel or wind generator, always produces electricity. Of course you can combine solar and the EFOY fuel cell.

All around carefree!

The EFOY recharges your battery fully automatically and maintenance-free. It turns on when the battery needs to be recharged and turns off again as soon as it's full. You only have to change the fuel cartridge when it is empty. Unscrew, screw on, done!

Enjoy the rest!

The EFOY produces electricity particularly quietly and is just as loud as a laptop fan. Noise pollution from loud diesel generators is a thing of the past.

EFOY fuel cartridges

EFOY fuel cells require our EFOY fuel cartridges to generate electricity. These contain high-purity methanol* and are a safety-tested system specially developed for EFOY fuel cells. You can easily change the EFOY fuel cartridge in a matter of seconds.
