Solar Panel Charge Port:Built-in DC 5-7V Input Interface. SMD LED Chip:66 SMD LEDs. Soft Light Lampshade:Do not hurt the eye sight. Large Capacity Battery:2500mAh Rechargeable Battery. Stepless Adjustment:Adjustment Freely Brightness. Technical Parameters: Model No.: DP-7103 Battery Capacity: 2500mAh Input Voltage:AC 100—240V 50/60Hz Input Current:AC 0.15A 1.2W Power: 6.6W Power Factor: 0.1 DC Input:DC 5-7V 0.6A (Can use the solar panel) Charge Time:15Hours Using Time: 3 Hours (Strong/Weak degree) Made In China Instructions: Connect the power supply, if charging indicator turns on, then it’s in charging status. Charging time needs about 15 hours. If it is recharged through sun power, the output working voltage is 5-7V, output working current is 0.6A. If it is recharged through charger, the output working voltage is 6V, output working current is 0.6A. When the light becomes weak during using, that means the battery is in lack of power. At this moment, stop using it and recharge it in time so as to protect the battery. Recharge it before the light is completely invisible, otherwise it will case damage to the battery. Frequent use is required, long-time nonuse is unadvisable. If you don’t use it very often, please recharge it every 3 months, or the battery’s life-span will be shortened. Cautions: Do not point the light to eyes directly, or it will affect eyesight. Children must be supervised by adults before using it. Keep it away from rain and dampness. Keep it away from the explosives and inflammable while it is charging.
