Why it is too long to charge the lithium battery of the solar charger using the panel compares using the USB cable?
Well of course using the panel to charge the battery will definitely take long because you are harnessing power from the sunlight, and harnessing light to collect power differs in different situation. One aspect is the size of the panel, because our chargers are compact on its design, the ability of harnessing power from the sun is affected. The bigger the panel the faster it collects power from the sun. It is also important to remember that solar panel is a renewable technology product that uses free and alternative energy which comes from the sun. Renewable energy is much different from the grid type power source. But the more we use renewable energy, the more we help the environment and lessen the threat of GLOBAL WARMING!
