Automatic 7-12mm Pencil Sharpener

The tenwin TW8819 is a battery-powered electric sharpener that accepts pencils from 7 to 12 millimetres in diameter. It uses a hands-free sensor to grip and sharpen automatically, then ejects the pencil when finished. A built-in 2000mAh lithium cell provides up to 600 sharpenings per charge and can be topped up via a Type-C port while in use. A breathing LED ring shows operating and charging status at a glance.

Home, School and Studio Users

This sharpener suits students, teachers and artists who want quick, consistent points without pressing buttons or holding the pencil. Three sharpness levels cover writing, sketching and shading needs. Buyers who need to sharpen pencils larger than 12 millimetres or who prefer a mains-only unit should look at a different model.

2000mAh Rechargeable Battery

The integrated 2000mAh battery delivers up to 600 sharpenings on a full charge and supports pass-through charging through the universal Type-C connection. This capacity decides whether the sharpener can last through a full classroom day or a long studio session without hunting for a power outlet.
