Portable handcrank emergency light with builtin super capacitors, USB output, PWM dimming, and plasma ignition. Designed for reliable emergency power, lighting, and ignition without dependence on mains charging. Key benefits Emergency power on demand: Handcrank generation supplies USB power for shortterm device charging when no external power is available. Long, controllable illumination: Stepless PWM dimming and a large COB light plate deliver usable light levels from longduration low power to bright shortterm output. Multifunction practicality: Integrated plasma ignition and a visible voltmeter add utility for camping, outdoors, and emergency situations. Clear status feedback: Red liquid crystal voltmeter shows realtime voltage and remaining charge, making it easy to plan use. Main features and specifications Energy storage: Builtin quality super capacitor configuration, capacity 20F*3. Voltage regulation: 5V voltage stabilizing circuit for steady USB output. USB output: 5V 1A USB output for emergency charging of mobile phones and small USB devices. Manual power generation: Handcrank output 0.56A at two turns per second, 0.8A at three turns per second. For mobile phone charging maintain more than two turns per second. Mobile phone charging intended for emergency use. Lighting control: PWM stepless dimming with brightness memory function. The unit automatically saves the last brightness setting when turned off. Light source: Oversize COB light plate for wide, even illumination. Controls and materials: Aluminum alloy knob for reliable adjustment and durable operation. Runtime examples: brightness operation approximately 20 to 30 minutes. Low brightness operation more than 8 hours. Ignition module: Plasma electric arc ignition capable of dozens of ignitions after brief manual charging. Ultrapower ignition module with pure copper ignition electrode post improves conversion and longevity. Do not touch the electrode post during ignition due to temperature. Status display: Red liquid crystal voltmeter displays realtime voltage. Fully charged remaining power shows about 9 to 10V. Practical performance notes Short manual charging yields immediate usable power. Handcranking at or above two turns per second is required for practical mobile phone emergency charging. Brightness memory lets you restore the last output level without readjusting every time. Plasma ignition provides a flameless way to light stoves or candles when conventional lighters are unavailable. Use scenarios Emergency vehicle kit: Keep in a car for roadside emergencies. Use the light for visibility, the USB output to up a phone during an emergency, and the plasma ignition to light a stove or candle if needed. Camping and hiking: Provide camp lighting with adjustable brightness and long lowpower runtime. Use the handcrank or USB output to charge devices when camping offgrid. Power outage and home emergency: Use as a reliable light source during blackouts, and as an emergency USB power source for essential communications. Safety and handling Do not touch the pure copper ignition electrode post during or immediately after ignition. The electrode reaches temperature. Use the USB output only for devices compatible with 5V 1A input. Maintain handcranking speed for intended charging performance. Charging mobile phones requires cranking at more than two turns per second. This product combines robust super capacitor energy storage, regulated USB output, adjustable efficiency lighting, and a plasma ignition module to address emergency lighting, shortterm device charging, and ignition needs in a single portable unit.
