szdealhola Hand Crank Generator Portable Emergency USB Charger

Supercapacitor embedded to store energy no regular batteries contained Plasma ignition hand-cranked igniter arc lighter can be ignited dozens of times by hand-cranking for 2 minutes. PWM(Pulse Width Modulation)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 energy storage for 20-30 minutes for high brightness and energy storage for more than 8 hours for low brightness. Red Led voltmeter instant 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 20Fx8pcs 5V voltage stabilizing circuit USB power of 5V 1A output hand-cranking for two cycles per second to generate 0.56A and three cycles per second to generate 0.8A. Mobile phone should be charged for more than two cycles per second which is only suitable for emergency use not for long time. Supercapacitor generators can be stored for a long time without maintenance and are not afraid of overcharge and overdischarge.
