Abstract: A smoke detector that comprises three different power sources. First one is the 110/220 volt AC house current, through a step down transformer or that can be hard wired into the home or factory. Second one is a moveable 9 volts rechargeable backup battery. Third one is a solar cell array with a plastic lens that provides up to 9 volts of current through a trickle charger/voltage regulator. The trickle charger also used to recharge the backup battery. With the trickle charger, the solar cell array can cause the smoke detector to alarm with only enough ambient light. The instant invention of the smoke detector unit overcomes the limits of the now market available smoke detectors, by being adjustable, moveable providing more current via the solar cell array to provide a complete recharge to the backup battery. Any voltage lower than 9 volts will lower the charge of the 9 volt rechargeable battery to the current 8 volts to 8 volts and so on up to 9 volts.
