The PowerFlight Mallard features weather-resistant housing for unstoppable performance in the harshest conditions –even 30 mph winds. Its lithium-ion battery runs for up to 16 hours of continuous use vs the 6-8 hour battery-life with the typical 6 volt, lead-acid battery. Recharging is easy using the external charging port. Also, hunters can use an optional 6-volt lead-acid battery in between charges. The PowerFlight Mallard includes everything the duck hunter needs to add life-like realism and duck-drawing power of motion –including the decoy, remote, rechargeable battery, charger, and a heavy-duty, marsh stake.
