Launched on September 17, 2024, the Longer Nano Pro is the lightest, fastest, and most accurate portable laser engraver available today. Weighing just 1.2 kg — about the same as a pair of sneakers — it delivers professional-grade engraving and cutting capability that rivals much larger machines. With a 12W 450nm blue diode laser, 5000 mm/s engraving speeds, and 0.01mm precision, it’s a machine that fits in a backpack but performs like it belongs on a workbench.

But does this compact powerhouse actually deliver on its promises? Here’s everything you need to know.

Galvo Technology: Blazing Speed Without the Bulk

Instead of a traditional rail system that drags a heavy laser head across the work area, the Nano Pro uses a galvanometer system that directs the laser beam using high-speed mirrors. This is the same technology used in industrial fiber lasers, and it delivers engraving speeds up to 5,000 mm/s — significantly faster than many conventional desktop lasers.

The preview speed is even more impressive at 32,000 mm/s, allowing you to position designs almost instantly. For practical reference, one reviewer engraved a logo in approximately 6 minutes at 80% power and 7000 mm/s. With its remarkable speed, the Nano Pro allows users to complete projects in a fraction of the time compared to other devices.

0.01mm Precision: Twice as Accurate as the Competition

At the heart of the Nano Pro 12W is its unparalleled engraving precision. With 0.01mm accuracy — twice as high as other portable laser engravers — this device allows creators to achieve the finest details in their projects.

Whether you’re engraving intricate designs on delicate materials or making precise cuts, the Nano Pro ensures that every line, curve, and edge is executed with flawless exactness. This level of precision is invaluable for artists and craftspeople working on detailed projects.

12W Power: 20% More Than Most Similar Devices

The Nano Pro 12W boasts 20% more power than most similar devices on the market, allowing for smoother, faster cuts with exceptional precision. This power enables the Nano Pro to cut through wood up to 10mm thick, a remarkable feat for a portable engraver of this size.

With the 12W version in particular, you get professional-grade engraving capabilities, allowing you to work on a wide range of materials with ease.

True Portability: 1.2 kg and Built to Travel

Weighing just 1.2 kg — about the same as a pair of football shoes — the Nano Pro is a breeze to carry around. Its lightweight design means you’re no longer tied to a fixed workspace.

You can easily take it to craft fairs, workshops, or even use it in different rooms of your house. The Nano Pro supports handheld mode by removing the main handle, allowing you to personalize items in ways that stationary machines simply cannot.

Distortion-Free Curved Surface Engraving

One of the Nano Pro’s most impressive capabilities is its ability to engrave on curved surfaces without distortion. The exclusive LONGER-developed algorithm adjusts the laser in real-time to follow the curvature of the material, delivering clean, sharp engravings even at the edges where distortion is often a problem with traditional machines.

Whether you’re working with cylindrical objects like cups or mugs, the Nano Pro ensures every detail is captured with stunning clarity.

These extensions are included in the Pro Set bundle, making it a versatile platform that grows with your needs.

Unmatched Software Compatibility

The Nano Pro is the first portable laser engraver with seamless compatibility with LightBurn and LaserGRBL. This has been certified by Diego, the developer of LaserGRBL.

In addition, LONGER developed the LaserBurn app for Android and iOS, allowing you to control the engraver directly from your smartphone. Whether you prefer professional desktop software or quick mobile control, the Nano Pro fits your workflow.

Build Quality and Easy Assembly

The housing of the laser is made of metal, as is the base plate. Everything appears stable and precisely manufactured, with no loose or rickety parts.

Assembly takes barely ten minutes. The device is ready for use in just four steps, and the well-thought-out cable management with color-coded USB-C ports makes confusion practically impossible.

Comparisons to Consider

Summary

Is it perfect? No. The base working area of 100×100mm is small. The lack of an IR laser means it can’t match the deep metal engraving capabilities of dual-laser competitors. And some users have reported Wi-Fi connectivity issues with LightBurn. But these are minor compromises for a machine that delivers professional-grade performance in a genuinely portable package.

If you’re a craft fair vendor, small business owner, jewelry maker, or serious creator who needs precision, speed, and portability — and who doesn’t want to be locked into proprietary software — the Longer Nano Pro 12W is the best portable laser engraver in its class.
