JUPITEARTH Electric Pencil Sharpener for Kids (Hands-Free, Rechargeable, Spaceship design) – Fits 6.9–11mm pencils
Product description
If you’re buying an electric pencil sharpener for a child (or a classroom), safety and convenience matter just as much as how fast it sharpens. The JUPITEARTH hands-free sharpener is built around automated “insert and it sharpens” operation, with several protections that make it feel more school-friendly on paper. It also aims to save pencil length by sharpening lead shavings rather than attacking the wooden body, which is handy when pencils are used hard.
That said, it’s not a one-size-fits-all miracle for every pencil you might own. It’s designed to fit specific pencil diameters (6.9–11mm) and it includes guidance about tip settings for softer lead, so it pays to match it to the pencils you actually use.
The essentials
This is a fully automatic electric pencil sharpener for kids, with a sensor-driven mechanism that sharpens once you insert the pencil and stops when finished. The hands-free concept removes the awkward (and potentially risky) step of using a knife or hand sharpener—especially in busy school mornings or after-school art sessions. On top of that, it’s described as preserving pencil length for longer use, which can reduce how often you’re replacing pencils in the first place.

It’s also aimed at everyday use, not just occasional sharpening. There’s a large inlet for wooden pencils in the stated diameter range, and a dial that lets you choose among five sharpening options for different tip styles.
What it’s like in day-to-day use
Using it is straightforward: lock the unit, insert the pencil, and let the sensor do the work. When it’s properly locked, the sharpener operates—there are clear lock/unlock indicators, so you’re not left guessing. When the job is done, it releases when finished, which helps prevent over-sharpening.


One practical example: imagine a child coming back from drawing with a stubby pencil. Instead of hunting for a hand sharpener (or reaching for a blade), you can lock the sharpener, pop the pencil in, and get a neat writing tip in seconds. The bigger shavings storage box also means you’re less likely to need constant emptying during a class activity.

Where it shines
A few things stand out for this kind of product:
- The five sharpening options (chosen via the dial) are aimed at more than just “write a bit”. You can select different tip sizes for writing, sketching, technical drawing and shading.
- Safety is a big part of the pitch: it only operates when locked, shuts off when the cover opens, and uses a blade holder designed to help prevent finger injuries.
- Overheating protection is included, with a red light triggered at 60°C to help protect the battery during heavier use.
- The case is made from impact-resistant ABS, and the UFO/spaceship-style cover is designed to be fun for kids rather than something that feels clinical in a pencil pot.
Things to watch before you buy

It’s worth checking the pencil fit first. The sharpener is specified for pencils in the 6.9–11mm range, including coloured pencils and No. 2 / 2B. If your pencils sit outside that diameter range, it may not work as intended.
Also, not every pencil is the same: the instructions note that you should use medium or blunt settings for soft-core pencils to avoid breakage. That means if your classroom or household includes lots of softer leads, you’ll get better results by selecting the right setting rather than trying everything on the sharpest option.


The rechargeable angle is convenient, but it does rely on battery performance. It can also be used while charging using the included USB Type-C cable (a 5V 2A adapter is recommended), so you’re not completely stuck if the battery is low.

Should you buy it?
It’s a solid pick if you want a safer, simpler way for children (or a classroom) to sharpen pencils without needing hand tools. The hands-free, sensor-based operation plus lock-cover safety features make it feel more controlled for regular use, and the five sharpening options help cover writing and art needs.
It may not be the best choice if your pencil types don’t match the 6.9–11mm diameter range, or if you’re expecting it to behave exactly the same across every soft-core pencil unless you adjust the medium/blunt settings. If you only sharpen very rarely and already have a trusted manual sharpener, the rechargeable setup may feel like extra faff.
