This power cell setup has both eliminated the need for an expensive AC to DC power source at home and also lets me charge batteries at the flying field all day without a generator. It's a relatively simple setup. Needless to say, anyone considering doing something similar must do their own homework and weigh and assume any risks involved.
Basically, the Power Cell acts as a giant reservoir or power and is trickle charged and maintained by continuous connection to the high quality CTEK charger connected to a standard home power outlet.
At home, I connect my charger to the power cell which provides ample power to charge all my batteries. If I go to the field, I simply unplug the charger and power cell and take them with me. At the field, the charger simply plugs directly into the Power Cell.
