With the EFOY fuel cell you always have your environmentally friendly power generator with you – in your motor home, on the boat, or in your shed or cabin. The EFOY fully and automatically recharges all common 12 or 24 V battery types reliably, quietly and in an environmentally friendly way. It requires no maintenance to do so-It switches on when the battery needs recharging and switches off again when the battery is full, you only have to change the fuel cartridge when it’s empty. EFOY is a space miracle; thanks to its compact design, the EFOY can be installed anywhere to save space.  

With EFOY there will be no more sweating in the sun; the EFOY Fuel cell always produces power, unlike solar panels or wind generators. Meaning that even in bad weather or during long periods of winter, you are always prepared.  

The EFOY produces quiet power and is as loud as a laptop’s fan. Noise pollution from noisy diesel generators is a thing of the past.  The EFOY generates environmentally friendly electricity. In a chemical process, only waste heat and water vapor with a small amount of CO2 are produced in addition to electricity. Therefore, the EFOY can be installed indoors without hesitation. You can control the fuel cell easily with the EFOY app on your smartphone or tablet. All you have to do is plug the Bluetooth adapter into the EFOY. In the app you can see all the information about your fuel cell and battery at a glance. You can also combine solar with your EFOY Fuel cell for more options.
