The invention belongs to the field of flashlights, and mainly relates to a power generation flashlight with an anti-reflection lens. The power generation flashlight comprises a front cover, a cylinderand a rotation barrel. A front cover plate is the anti-reflection lens. The cylinder comprises a power storage device and a power generation device. The power storage device comprises an LED lamp, aswitch, a capacitor and a circuit board, wherein the LED lamp, the switch and the capacitor are connected with the circuit board. The power generation device comprises a power generation coil, a magnet coil and a planet gear set. The rotation barrel is rotated to drive the planet gear set to drive the magnet coil to rotate, the magnet coil does the rotation shaft movement relative to the power generation coil, a magnetic induction line is cut, and accordingly current is generated and stored in the capacitor for lighting. Compared with the prior art, battery replacement is not needed, rotationis utilized for self power generation, planet gears are arranged inside, labor is saved, the generating capacity is high, and high efficiency and practicability are achieved.
