【Voltage/Current】: 3V / 6.6A, 5V / 4A, 6V / 3.3A, 9V / 2.2A, 12V / 1.6A, 15V / 1.3A (The current is an unloaded current connected to different products. Load current changes after charging) 【Manual power generation for environmental protection】: multifunctional, can charge for mobile phone, USB night light, USB fan, power bank.Practical, suitable for use on site, field operations, field trips, rescue operations, natural disasters, survival training, emergency communication, long-term power shortage, tourism, etc. Emergency generator: manual crank generator, a nice helper under emerging scope. Energy-saving, environmentally friendly and with many interface types. The faster the rocker power, the higher the generation power and voltage. Shake the generator, the output voltage must be greater than the setting voltage to regulate the output voltage. 【Portable】: 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. 【Convenient for going out and exploring】: metal housing durable, high-quality bearing, effortless and time-saving. Small and exquisite, convenient to assemble, easy to carry and with internal power storage function. › See more product details; Product description Features: Portable hand crank generator, can be used as an emergency power supply.
