Wirst that can happen is that the devices draw too much power, potentially overloading the port. Still, Apple laptops have best USB surge protection on the market, so I wouldn’t worry too much about this.
 
I had my 2012 MBP lose one of its ports, so it's natural I'm a little concerned. If this happens, can any steps be taken to fix an overloaded port?
 
I guess you go to Apple or a third-party service provider and have your logic board replaced... should count as a warranty case though.
 
I have only once seen a port get burned out (2014 MBP 13" SD Card slot), and that was because the user was using the card slot as a permanent external storage.

The USB-C ports on these computers are pretty hardy and can take a lot of I/O usage. There are lots of people who use Caldigit or OWC docks which can support 6 plus devices and I haven't seen any reports of issues with the USB-C port(s) burning out. I personally use a Caldigit dock which powers my 2017 MBP wTB, has two external displays and two external hard drives plugged into the dock, all plugged into just one USB-C port on my machine, and I have not had any issues at all.

My main suggestion is buy a dongle or dock from a reputable brand name you recognize. Cheaper brands are more likely to cause issues and possible mess up your computer's I/O ports. Often times the cheap brands aren't even to spec for proper USB-C safety standards.

I would aim for brands such as Belkin, Anker, Hyper, Caldigit, OWC brands. They cost a bit more but are more reliable and safer for you computer and your external devices. The one you listed on eBay I would hesitate on, as it doesn't even list the brand name.

Thanks, that eases my mind about it. Is there a particular adapter that you'd recommend? Here's what I need:

- At least one regular USB port
- Ethernet
- Either Thunderbolt or HDMI

It's okay if it's multiple adapters instead of one. But the less, the better. And the cheaper the better, so long as it's safe to use.
 
I don't know, but that seems to me to be a really good price---like too good to be true.

Dose it have any issues?
I have no clue, as I've never owned one. But eBay has a lot of listings of similar devices, with the HDMI+Ethernet+USB setup, with varying prices from $15 to $30. The sellers have good numbers, like "97.1% Positive feedback".
 
The bigger issue is that most of these hubs have short cables to connect to the laptop, and the input ports are often on 2 if not 3 of the sides of the hub - so if you are connecting desktop usb-a devices, HDMI, and Ethernet, you have these comparatively thick, heavy cables coming in at different directions. That, plus the fact that Apple’s usb-c ports tend to be looser than other brands, means that it can be hard to maintain a consistent connection.

I would look for something that either has a removable usb-c cord, which is usually a full dock, or one of the types that has the usb-c male port built in and fits flush with the side of the Macbook. So long as you use this latter type primarily on a desk it should be less cumbersome.

By way of comparison, the Apple sold dongle with just USB C, HDMI and USB A costs like $70.

This one has all of those, the USB C looks to be power pass through and there is an Ethernet port for a third of the price.

It’s almost a little concerning—there’ve been a lot of problems with funky USB C cables from China.

That does seem pretty suspicious, then. Though I would guess that $70 is a premium price, and a good one doesn't have to cost that much.

What are the kinds of problems that can be caused by USB C cables from China?

Do either of these look okay?

The reviews aren’t good, although I would generally trust a product from New Egg.

From what I recall, the cheap usb c cables were frying logic boards. https://www.techlicious.com/blog/budget-usb-c-cables-can-fry-devices/
