After doing extensive research, I have come to the conclusion that a 20W laser engraver is actually a very powerful machine. Its advanced laser technology enables it to cut materials that other laser engravers cannot. The optical output power of the 20W laser engraving machine is one of the strongest diode lasers at present, and its cutting ability far exceeds that of other engraving machines.

During my research, I found out that the LONGER Ray5 20W Laser Engraver is one of the most powerful machines on the market. The machine is capable of cutting materials such as paulownia wood, black acrylic and even stainless steel in one pass. This was especially impressive to me because I've used other laser engravers in the past that had a hard time cutting these materials, even after multiple cuts.
