If you connect a load to it you will see right away what is capable of doing. I have bought something similar a few years back, and it could bearly deliver a few miliamps.
Of course, this is good for a multimeter 9V battery replacement, maybe an acoustic electric guitar preamp...but I doubt, I'll never use something like this in any audio environment. Or, let's say a radio receiver working with 9V... I'm pretty sure at least on AM it will be impossible to reach any station because of harmonics and artifacts generate by module.
@@ugandanknuckles3429 For a multimeter it's perfect ! But I will avoid use it for any audio and radio applications. There are a lot of RF artifacts around.
Thanks for the information, I can use two lithium batteries in series with the module
I don't think so, this is for a max 4.2V cell...of course you may use as many cells in parallel.

@@viocaiayeah I just used something similar to let my multimeter run on 18650's. Pretty nice for stuff like that
