High efficiency power generation: the speed of the hand crank power generator is 2000 rpm. The power generation power is about 20 W; if the speed of the hand shakes faster, the higher the power generation power, the higher the voltage of the power generation Power parameters: the corresponding voltage current: 3 V/6.6 a, 5 V/4 a, 6 V/3.3 a, 9 V/2.2 a, 12 V/1.6 a, 15 V/1.3 A. The output voltage of the hand crank generator must be greater than the setting voltage and pay attention to the stable output setting voltage Portable and compact structure: portable manual generators are easy to start, easy to carry and always ready to start. Easy and quick to transport thanks to lightweight construction; solid structure, low noise and stable working performance USB crank generator: the USB charge generator with high performance, which significantly improves its use, makes it more portable and is very suitable for emergency situations outdoors. If you use the USB port external electrical appliances, please adjust the voltage to 5 V first Widely used: portable manual generators can be used as an emergency power supply. When no power generation is required to use electricity, this can be used by workers and power generation to provide various electronic products. The ideal for caravans › See more product details; Product description Features: Portable hand crank generator, can be used as an emergency power supply. High performance USB charging generator, strong power generation. Solid structure, low noise, stable working performance. The higher the speed of the hand crank, the greater the force. The maximum output is approx. 20 W. Compact size, light weight, easy to use. It can be used in field operations, field trips, rescue operations, natural disasters, survival training, emergency communication, long-term power outage, tourism, emergency power, etc. Specification: Condition: 100% Brand New Material: metal.
