Most of the mobile power supplies on the market are very round, so the shapes are very similar.
In fact, 10000 mA mobile power supply is very heavy. I found that users will use it in their bags...
Therefore, the round shape will make the mobile power supply lie in the bag and take up space.
Therefore, the design of a square shape can make him place on the side of the bag more stably and reduce the use space.

The picture processing is very beautiful and worth learning, but how did you come to the conclusion that the current charging treasure is very round? Most of them are more square
Can the charging treasure stand up in the bag? shouldn't it be related to the bag itself? can it stand side for a long time as people move around? In the end, it is not lying down
The graph processing is very advanced.
nice
This one is really not round
