Solar USB Desk Lamp

I wonder how i am going to charge this Solar Desk Lamp? Lamps are generally used in dark places where there is no direct sunlight or at night time when we already face shortage of natural light. So if i have this Solar Desk Lamp, i will have to take it out to my lawn to get charged in the day time and then use it in then night time . The other alternative charging system is the USB based and i think it should be the primary charging system and the solar panel is just a “trying to be green” addition.
