"This technology uses mechanism design so that it can be easily installed on the motorcycle suitcase,uses solar panels for energy harvesting. The harvesting energy from harvesting IC is stored in the 18650 lithium battery for reuse. The patented LED drive circuit drives a 1W LED lamp with current limiting circuit for internal lighting,provides a 5 V 3 A USB charging system using a boost current limit circuit for the lithium battery voltage,has an under voltage lockout function to prevent battery over-discharge."
