The EFOY 900 fuel cell has a capacity of 900Wh per day, that is enough to keep you energy independent from spring until summer in your mobile-home or sailboat. You can also use it as an adjunct in the winter. It does not just deliver clean and quiet electrical power. It also does so reliably and effortlessly whenever you need power, day and night, regardless of the weather, anywhere.
EFOY fuel cell is so quiet that it won't disturb your sleep. It is economical and free from harmful emissions. The only things that the process produces besides electricity are water and carbon dioxide in amounts no more than a child's breathe. The 'Automatic Charge Control' permanently monitors the battery's voltage level. Once the voltage dips below 12.3 volts, the EFOY fuel cell cuts in automatically and recharges the battery. Once it is finished, it switches itself off again - fully automatically.
