Racket (‘Hand Held Bug Zapper’) > The racket produces a charge imbalance, known as static electricity, (although electricity is never static). > There is a red light that comes on when you press the on/off button (no cumbersome safety switches.) > This charge is enough to zap a mosquito dead, KILL a fly or zap off a wing or a leg or both! How Does it Work? The bugs serve as conductors between the imbalanced rods. Holding the power button on, immediately charges the grill. When you hit the insect, the racket makes a NICE spark and a LOUD SNAPPING. sound when its static electricity is discharged to the insect, (Much like those portable insect zappers.) Is it Safe? Yes, it is CE certified safe. RoHS Certified. Warranty: One Year Limited Included in Each Purchase: Quality Bag with carry handle. #====== Power source: 2 ‘C’ batteries (not included) # Input Voltage: 3V,… (and NO, you cannot increase it with more power!) # Output Voltage: 4,000,… (possibly reaches 4,200V during the actually zap) # Input Amps: 0.24 ~ 0.26A,… Output Amps: 0.23 MA (plus or minus)
