Do you have any contact information? I need to design a private mobile power supply

The design is getting better and better. It is better to select subdivided products for in-depth research. Digital and small household appliances industries have money. Combined with innovation space and marketing, digital products focus on earphones, Bluetooth speakers, intelligent robots and mobile power supplies. These products are good. Don't waste energy on other small things.

What kind of rendering do you use? The power display shows that the rendering is very good, and the color matching is also very good. I like it

Great!

It's really nice.

There are indeed several colors.
