I have several cheap USB to barrel plug (to fit OrangePis, 4.0 x 1.7) adapters here and some seem to start failing.

 

o cut a long story short, does anybody have recommendations on what product to buy to get such a cable with better quality?

I always use a short barrel adapter cable to convert to a standard sized barrel plug (5.5mm x 2.1mm). I would throw these short cables away if when they wear out. It would also save wear and tear on the board connector.

I soldered these to my PowerSupply, you could as well solder it to an USB-Connector... DC Power Plug Male Connector 4.0x1.7mm Male Socket With Cord Cable,DC pigtail 4.0/1.7mm /Free shipping/10PCS

I didn't test them on "how many cycles" they last, but I like the sealed barrel. To solder the barrel was always the weak spot to me.
