Specification-------------------------------------------------------------- special reminder: 1. Please do not short circuit the generator, otherwise the voltage stabilizer will be burned 2. Do not connect the generator directly to the battery, and must add rectification to prevent backflow from burning the voltage stabilizer board Hand crank pedal type multi-purpose generator With voltage limiting voltage regulator, the voltage can be adjusted to 12V This generator is a low-speed DC permanent magnet generator, with a normal speed of hand cranking, a voltage of 12V at 60 rpm, and can carry 100W 12V electrical appliances. Note: The user needs to add a 14.5V voltage regulator to change the hand-cranked charger Send: 1. Send rectifier 2. Hand crank 3. Bracket 4. Voltmeter Aluminum alloy type (6A with voltage stabilizer) The output terminal cannot be short-circuited, otherwise the voltage regulator board will also be short-circuited Can super fast charge mobile phones at the same time (requires original car charger) Can charge 2-mobile phones at the same time The output terminal cannot be short-circuited, otherwise it will burn the voltage regulator board If you need a test operation video, please contact us.
