Hand generator | Portable | Lighting | Ignition |USB Charging Version 1.0V: fully charged 9V 20F*3 COB lamp board (bright for 20-30 minutes and low for about 8 hours) can ignite for 30 times. USB charging needs about 2 cycles per second (fully charged, it can last until the voltage drops by 4V). The capacity is small, the voltage drops quickly, and it needs continuous rotation. Version 1.1V: fully charged 6V 20F*8 COB lamp board (high brightness lasts for 50-75 minutes and low brightness lasts for about 20 hours) can ignite for about 70 times. USB charging needs about 2 cycles per second (fully charged, it can last until the voltage drops by 4V). The capacity is 2.5 times higher than that of version 1.0V, and it can not be shaken for a short time. Version 1.2V: fully charged 8.4V 600mA*2 COB lamp board (bright for more than 10 hours and low for n days) is untested, and can be ignited for n times for USB charging (fully charged, without shaking, it can last until the voltage drops by 5.4V) for low-voltage protection. The capacity is increased by n times compared with version 1.0V, so it can be used as a small charging treasure, and the charging time by hand is longer. Description: Plasma ignition, hand-cranked lighter, hand-cranked igniter and arc lighter can be ignited dozens of times by hand-cranking for 2 minutes. PWM stepless dimming, aluminum alloy knob, oversize COB lamp panel, with brightness memory function, automatically save the last brightness when turning off the lights, hand-crank for 2 minutes, battery life for 20-30 minutes for high brightness, and battery life for more than 8 hours for low brightness. ABS case acrylic transparent panel, CNC computer hole processing, beautiful and practical. Red LCD voltmeter, very intuitive display of real-time voltage, remaining power, fully charged 9-10V. Ultra-high power ignition module, pure copper ignition electrode post (it is very hot, so don't touch the electrode post when igniting). Built-in high-quality super capacitor, capacity of 20F*3, 5V voltage stabilizing circuit, USB output power of 5V1A, hand-cranking for two cycles per second to generate 0.56A, and three cycles per second to generate 0.8A The mobile phone should be charged for more than two cycles per second, which is suitable for emergency use. Supercapacitor generators can be stored for a long time, without maintenance, and are not afraid of overcharge and overdischarge. Suitable for outdoor camping, power-off lighting, emergency charging, DIY experiment, leisure decompression, appreciation and collection. Generator size: 9.8cm*6.6cm*3.6cm Pcacage include As your choosed ,Please check ,thanks !
