electric pencil sharpener pencil shapper full-automatic power supply battery dual power supply

The new and improved version of the 220V DC electric pencil shaver has been launched!

This electric pencil sharpener is a significant improvement over the old model. It can be powered by batteries, but also has the option to plug directly into a 220V AC power source using an adapter or directly into a computer via USB. Three ways to use: at school with batteries, at home by plugging in or using it on a computer. It's energy-saving and eco-friendly, making it easy and cost-effective to use. You can use it however you want.

Please note: This product is powered by a 4.2V, 1A power supply. It should only be used with a specially designed power adapter. Although it is equipped with a USB port, the current from a laptop is small, so please do not use it with a laptop to avoid damaging it.
