is my third party steam deck harmful to its battery?

[Awesome Onion (S.D.F)]

I don't want to spend 90 euros just to connect my deck on a monitor, so i found a sort of usb-c dock that is used on a laptop, with ethernat cable, hdmi, and etc. but most importantly a usb-c charging port in which you can plug the steam deck charger in it and play with the console while it's charging and also displaying on the monitor,
it is working fine, but my question is: can it be harmful to the device if it is not the official one, also because it really isn't a dock for steam deck?
i don't want to ruin my console

Hello! You should be perfectly fine: I've used a cheaper 3rd party dock since July of last year for my steam deck - stays plugged in roughly 95% of the time - that I plug the steam power adapter into as you described.
Steam deck has "Power Delivery 3.0" so even excluding the steam power adapter, any usb-c charger that uses the standard usb-c (delivering 45 watts) should work just fine.*

As always with 3rd party, there is 'some' form of risk: Nintendo Switch for example had a 3rd party dock incident in like 2018 that killed a bunch of switches after nintendo did some firmware power delivery update that the 3rd party (more so the power adapter) didn't know what to do and fried the switch. But this instance is worth noting that nintendo 'doesn't' use the standard usb-c protocols (which the steam deck does), so the chance of this specific issue is unlikely. But the main warning I wanted to mention - although very rare I feel to occur - is you have to put some trust in the 3rd parties to make a decent product and won't cheap out in way that could break something in the future. Thankfully docks - honestly I don't like calling them that and wish we'd just call them usb hubs with power delivery - are pretty straight forward and the likelihood a 3rd party company would mess that up is similar to expecting them to mess up another well known tech at this point like computer LCD monitors (you can buy a cheap 1080 monitor for around 100 bucks from an off brand and it will likely work just fine). So chances are not 0%, but highly in favor of being perfectly fine.

Hope that helps! Cheers!

Edit: and to answer your title regarding the battery: it shouldn't wear the battery anymore than the normal dock would. I wish valve would allow us to cap the battery to 60%-80% for us folks that have the steam deck plugged in all the time. Maybe someday!

*An example of a bad power adapter would be the nintendo switch power adapter. Don't use it for the steam deck. But most usb-c adapters should use the standards correctly.

Not needed. The Deck already performs battery health management when plugged in.
