The light device has USB charger has AC outlet power source has though the AC-to-DC device to change from 1st Alternative current to 1st voltage Direct current and the 1st voltage DC current though the circuit-inside or IC or DC-to-DC circuit to get 2nd voltage or though more DC-to-DC devices to get more voltage DC current. The light device has At least one of voltage DC current to supply to USB Charger Charging-port output-end at 5 Volt and one of desire voltage DC current to supply to DC light source. Or/The 1st AC current to AC light source and has one of DC current selected from 1st, 2nd or more voltage DC current to USB Charger charging-port's output end so the said light device has (1) illumination function by DC or/and AC light source and (2) USB charger function by supply desired 1st or 2nd or more other voltage DC current to USB charging-port at 5 Volt DC. The light device optional has outlet-ports to get 1st AC directly though conductive parts to outlet-ports to supply AC to other device. Furthermore, the light device Optional can add other function(s) select from (a) Time piece related (b) Reflect Image (c) Power station (d) project image (e) heater (f) Air Flow (g) wireless communication (h) remote controller (g) APP controller (h) Blue-tooth controller.
