Product function description:1. INPUT: directly charge the product through solar energy. Intelligent charging, maximum charging 910MA.2. Press the ONOFF switch to automatically charge in the daytime and turn on the light at nightProduct parameter description:1. Built in battery: 2200MAH/3.7V 18650 cylindrical battery 2PC2. Solar panel: 200 * 170 * 2MM5.5V 5W tempered glass3. Laser lamp: green light: 20MW @ 532NM, red light: 30MW @ 650NM4. Working current: about 1000MA5. Light spot: more than 3000 firefly spots6. Lighting time: charge for 5-6 hours in sunny days, can work for 6-8 hours, project 10-20 meters away, and cover 50-100 square meters.Product protection function:1. Charging protection: after the charging is terminated, the battery voltage is 4.2V-4.25V.Charging voltage higher than the rated voltage will limit charging to protect the charging circuit and battery from damage.2. Discharge protection: after the product output and the laser lamp automatically stop working,the battery voltage is 3.0V~3.1V, and the function cannot be used again until the battery voltage is higher than 3.3V.3. Over current protection: If the output current exceeds the rated current, the product will cut off the output immediately4. Short circuit protection: In case of short circuit, turn off the power supply of the whole machine immediately,and it can only be used again after solar charging is activated.Usage method(1) Press the ON/OFF switch to turn on the intelligent mode (automatic charging during the day,automatic lighting at night), and the product can work normally;(2) Fix the ground plug and connector of the solar cell box laser lamp accessories,then connect the solar cell box and laser lamp through the waterproof interface line, tighten the screw cover,and fix the solar cell box in a sunny place, and install the laser lamp in the courtyard lawn and other places[Working time]: 6-8 hours[Charging time]: 5 hours[Shell color]: black[Working mode]: automatic charging in daytime. Automatic lighting at night[Shell material]: ABSPacking including:1x projector lamp1 set of supportsMatters needing attention(1) Because the conversion efficiency of the solar panel is affected by the light intensity,the continuous luminous time of the laser lamp will be different due to weather conditions, seasonal changes,geographical location and other factors. This is normal.(2) The product can be charged only when the key switch is set to ON, and it lights up automatically at night.(3) The waterproof design of the product is limited to rain and moisture. Do not immerse the product in water for a long time.(4) Please do not hit or strike the product violently to avoid damage.(5) One end of the inserting rod is very sharp, please pay attention to it completely when using.
