There are loads of switching PSUs on Aliexpress with the same form factor. I have one (€30), and have seen a few teardowns/reviews of similar ones.
Filmsy construction, loads of output capacitance with bad transient response, terrible protection, noisy...
This one might be better, but I wouldn't buy it without watching a proper teardown and safety review from a knowledgeable engineer. Also, a linear PSU and two decent multimeters are often the first thing newbies buy. Having the DMM integrated inside a switching PSU, with unknown isolation, noise inmunity and input protection would make me a bit nervous TBH, and would not recommend it upfront.
I don't do streaming, videos or anything, but could do a screen capture of any of my instruments without any problem really. Maybe it is a worthwile investment, but that would be proven by a proper hardware review and tests.
