Is it the outlet? Is it the dock? The power brick? The usb c cable? I honestly don’t know. This is what I’m using:
Dock: JSAUX Docking Station Compatible… https://www.amazon.com/dp/B0B28PCDM2?ref=ppx_pop_mob_ap_share
Brick: UGREEN 100W USB C Charger, Nexode… https://www.amazon.com/dp/B091Z6JNX4?ref=ppx_pop_mob_ap_share
Cable: https://share.temu.com/tw2FkuTn6LA (I will admit I cheaped out on the cable)
Is there alternatives to anything I’m using that you guys recommend?
Is there something to make my outlets output the sufficient wattage or whatever to properly charge the deck?
That cable is rated properly for your use, though the one from your OP is also properly rated, and very broadly the stuff you get from Amazon from a reputable brand is going to be fine. The dock is probably fine, as well.
The monitor shouldn’t affect anything regarding charging, as long as you pay attention to the ports you use, as detailed in my other comment.
