Green Union 300-watt charging module housing
Print Profile(1)

Description
I bought two Green Union charging modules on Xianyu, very cheap, and the wires on my desk for the mouse and keyboard were a bit messy.
I felt that the existing solutions weren't perfect, so I made one myself, adding a DC current display and passive heat dissipation.
In actual use, it gets a bit hot at a sustained 100 watts on both ports. I feel that the plastic print can't handle it for extended periods. If you need one, buy an aluminum alloy one. I only have one high-power device, an Apple high-power device (27 watts haha). The mouse and keyboard use very little power. Adding an aluminum module keeps it essentially cool.
There are also pictures of the soldering. Study them, it's very simple.
I used a Mean Well S-350-27 power supply for the input power, which can be adjusted to 29V. The Green Union module can't exceed 29.5V. The Mean Well output isn't necessarily precise, so 29V is the safest bet.
The dimensions of the aluminum alloy heat sink module are 10*35*10, bought from Taobao for 3.5 (needs to be cut to about 8cm long).
The DC ammeter was 5 yuan from PDD.
If you need one, please like it.
