Davuaz Da-K6402W Management
This is an unmanaged switch. We could not find a management interface. For a switch in this price range, perhaps that is exactly what folks want.
Davuaz Da-K6402W Performance
In terms of performance, this seems to be a decent, but not top-tier performer.
Again, for a sub $70 switch this is not bad. It is also virtually identical to the YuanLey.
Davuaz Da-K6402W Power Consumption
Power adapters are always an interesting point. This comes with a few markings but we do not see things like UL or FCC markings as we did not see on the YuanLey. It is only a 12V 1A power adapter, so we know this is going to be a low-power device.
At idle, we got around 1.6W just like the YuanLey. With a single 2.5GbE port plugged in, we added 0.7W for 2.3W total.
We used a 10Gbase-T SFP+ pluggable to add a good amount of power consumption in a SFP+ port and we got 2.7W for 1.1W over our baseline. This was 0.3W lower than the YuanLey, but since we have identical PCBs and identical power adapters, we are not going to say this is lower power. It feels more like manufacturing variability if anything. Again, it is only 0.3W.
As with the YuanLey, we tried powering this over PoE using a splitter, and it worked. While this does not have PoE-in, a cheap splitter got us the power we needed to the switch just given it is such a low-power device. Perhaps that is not the best idea, but it worked.
Again, we do not get a lifetime warranty, regulatory markings, or similar. On the other hand, it is cheap.
This is a fanless 2.5GbE and 10GbE port switch for under $70 that is good enough to set up a small network. While there may be better switches on the market, the only one that is close to this is the YuanLey. The YuanLey is probably better with that thermal pad between the PCB and the chassis on the bottom, but they are effectively identical. We would not pay a premium for the Davuaz over the YuanLey, but if the Davuaz was $5 less expensive one day, this would be our choice.
Overall, this is special because it is small, cheap, fanless, and not because it is some amazing hardware. The big feature here is that the switch is a new level of “cheap” and has this new port configuration. At $130, this would not be a recommendation, but we paid half that price and the only real competition is the clones of this switch model.

Ultimate Fanless 2.5GbE Switch Buyer’s Guide
You may have seen that we published the Ultimate Cheap Fanless 2.5GbE Switch Buyer’s Guide. Here is the video for that one where this switch appeared.
We decided to do the round-up first and will be filling in with reviews that we had not published at that point, including this one. We are trying to keep everything in a single resource for folks there.
