Two figures in watts, and only one of them leaves the lens · review
An open-frame diode engraver stating 20 W (20,000 mW) of laser output, a linear-guide structure, and control by Type-C cable or USB stick.
A 20,000 mW figure is what a diode buyer needs to see, and many listings print only electrical watts. Compare it with the 10 W and 5 W machines here.
ATOMSTACK builds the frame around an integrated linear guide, which it says speeds assembly and adds stability. Control runs by Type-C or a USB stick.
The open frame is the catch. Budget for an enclosure, a fume extractor and eyewear marked for the wavelength.

The listing says 20,000 mW of output laser power, which reads as optical output rather than electrical draw.
The machine is an open frame. Follow the maker’s instructions on eyewear, ventilation and enclosure before you run it. This is a laser product. Read the class on the label and the maker’s instructions on eyewear, enclosure and ventilation. This site does not call any setup safe.
7.7/ 10
The power pick for the price, with a real output figure. An open frame means extra spending on an enclosure, extraction and eyewear.
workshop machines from the same category, at nearby prices. Only what all of them publish is shown: a column with holes compares nothing.
