USB Soldering Iron (MP740142)


I had a really good experience with this soldering iron. Being powered by USB is not a problem at all, it does the work and I didn't have any problems with it. One thing important that I noted in this iron is about the USB charger I used to power it. Below, the in the left which is rated for 1.55A takes around 55 seconds from cold to 300°C, while the black one on the right side, rated for 2A takes 30 seconds for the same temperature variation.




In the video below, I explore how it works and I also put my hands on soldering. I didn't show in in the video, but I also tried 0603, 0805, and SOT23 footprints and was just easy. For the fine pitch shown in the video, it would be better if I had a conical tip like this one, but it worked as I did as well. In reality, with the type of tip that comes in the soldering iron, I could do a lot of soldering for years, but sure, with the right tool, the work is better and quicker.image

Iron Tips

Below is the iron tip in detail. The system of quick tip exchange is indeed cool and was a super positive point for me.


The connector is an audio jack P2 style. Searching for replacement tips I found this, but not sure if they are compatible. Certainly, they are but it would be better if this information was explicit.
