Rechargeable Auto Eject Pencil Sharpener

A compact, portable electric pencil sharpener measuring 12.5 × 8.5 × 10.5 cm and weighing 320 g. Compatible with pencils 6–7.8 mm in diameter and as short as 6 cm (2.4 inches). Made from robust ABS plastic with a high-tolerance helical cutting blade. Powered by a 1000 mAh internal lithium-ion battery enabling roughly 300 sharpenings per full charge. Charges via standard USB cable (power adapter not supplied); operates normally even while charging. The large-capacity transparent shavings reservoir reduces cleaning intervals. Two distinct sharpening modes offer controlled tip formation — avoiding both blunt ends and fragile points — and integrate a lead-fracture prevention system validated for graphite, coloured, and standard pencils. Automatic operation includes detection, clamping, controlled rotation, and clean ejection — all completed in 4–8 seconds without user intervention. No physical contact with moving parts is needed. The motor stops precisely once optimal sharpness is achieved, protecting pencil length and preventing overheating or blade wear from prolonged engagement. Suited for children’s study desks, teacher resource carts, craft rooms, and freelance designers who require reliable, quiet, and safe sharpening without outlet dependency.
