It's a new product this year, and it's about to replace the M series, which we're calling the N series. It has been upgraded again compared to the old one. First of all, its styling has become more modern and classy. Secondly, we made a heat sink on the back cover plate, so that the power supply can get better heat dissipation and get a longer service life. Finally, we upgraded the curve lock with a bigger bending angle (+-15°), which can bring a better styling effect. Although the product has been upgraded, the price is still very beautiful.
