Chapter in this post:
Since Apple completely switched the MacBook models to USB-C, the accessory manufacturers for USB-C devices have hardly been slowed down. For this reason you will find no fewer than 15 brands on Amazon that offer their devices if you search for the term "USB-C Dock". Yes, my special favorite is that Belkin Thunderbolt 3 Express Dockthat will sooner or later end up on my desk. But currently it is about a much cheaper mini-dock from Egolggo (QacQoc), which is especially interesting for people who only want to connect a few devices with the old USB-A connector to the MacBook Pro and who now and then use the built-in SD Missing a card reader that was still found in old MacBooks.
So that there is no confusion that the device can be found with me under the brand name QacQoc and with Amazon under the brand Egolggo: These devices are 100% identical. I ordered the Egolggo Hub on Amazon, but the brand name QacQoc is on the packaging and on the device itself. The model name GN28A can be found in both sources.
The scope of delivery for this device is actually limited to the QacQoc Dock itself, as well as a small cover made of synthetic leather and a quick guide. The technical data is a bit more complex, because the dock's two parallel USB-C ports mean that it can only be used for the matching MacBook Pro models. And that would be the following:
Here are the specifications according to the instructions:
You can reach the Egolggo / QacQoc support via email email@example.com.
With regard to the devices that can be connected, there are still some limitations in the instructions, but I cannot confirm all of them. I have listed them here and wrote my experiences behind them:
The manufacturing quality of the dock is definitely high. The case is made of an aluminum alloy and it clicks into place cleanly when you plug it into the MacBook Pro. The connections are also fine. Problems with inserting the micro SD card, as I have already experienced with other card readers, did not arise here.
Another plus point, which unfortunately cannot be taken for granted with this type of mini-docks: You can operate two USB-A hard drives at the same time without an external power supply. The devices together may consume a maximum of 1,5 amps. According to the USB multimeter, my mobile 2,5 inch hard drives consume approx. 500 to 600 mA each. So there is still enough room for improvement.
With other docks it has happened to me that after a few minutes the hard drives were suddenly disconnected because apparently there was no longer enough power available for a short time. In the worst case, this can lead to data loss, because if the disk is busy rewriting its "table of contents" and you then unplug it without logging it off first, it becomes unreadable for the computer. Then only helps here Data recovery software and good luck.
With the QacQoc USB-C multifunctional hub, the disks ran through the entire time without interference - that's how it should be.
I had already tested some of these mini docks. In the best case, you have charged my MacBook Pro with 40-50 W, which is usually only enough to keep the MacBook happy in terms of batteries. There could be no question of a full charge.
That's why I was excited about the QacQoc Dock to see what it could deliver in this regard. To find the limit, I discharged my MacBook Pro a little on battery power and then with it Photolemur optimized a few photos. The program already got my old MacBook Pro (2012) going, and that's how it was here. When the software is busy calculating, the display is at maximum brightness and the battery is also being charged, the mini-hub draws approx. 4 amps of current. This allows you to charge the MacBook Pro with around 80 W via the USB-C hub - just as it works directly via the USB-C port on the MacBook Pro. Another hurdle that the QacQoc Mini-Dock has mastered.
To check whether the dock is slowing down the connected devices (hard drives, USB sticks, SD card, etc.), I made various speed comparisons with the Aja system test carried out.
I used the following devices for the tests:
The first thing I tried was the SD card port. The SD card was tested once in the Egolggo Hub and once with the Kiwibird USB-C card reader directly on the MacBook Pro.
With the Kiwibird card reader, I achieved a transfer rate of 10 MB / s (writing) and 19 MB / s (reading). While the dock also managed 10 MB / s when writing, but the Kiwibird SD card reader "ran away" when reading with 81 MB / s.
As mentioned above, the USB-C hub has two USB-A sockets. I connected the Seagate hard drive to both and wrote a 4GB file with the benchmarking software Aja System Test and measured the average speed. For comparison, the same hard drive was then plugged into the Anker USB-C adapter and directly into the MacBook Pro. The following results came out:
In view of the sometimes strong fluctuations in speed (which arise, among other things, when you test the data throughput when the Mac is doing other things in the background here and there) I would say that you will not notice any noticeable difference.
Anyone who is fundamentally interested in whether a hub slows down data transmission can do this read my test with a USB 3.0 hub.
It is already in the manual that the two USB-C ports are not "full-fledged", but I still wanted to try out what works in practice with the ports.
My 2,5" hard drive could technically be connected to both USB-C ports of the hub with the adapter, but it only worked when connected via the USB-C charging port in the Finder mounted. In practice you will hardly do this, because without the charging port you would have to plug in the charging cable on the right side of the MacBook Pro and then you can rather plug the hard drive on the right side of the MBP and the charging cable into the designated port on the USB-C hub.
The speed of the hard drive is also slowed down a bit at the hub's charging port and brings about 86 MB / s (write) and 84 MB / s (read).
In practical terms, one USB port on the hub is intended for the charging cable, while the other port is used to connect your iPhone (with a Lightning to USB-C cable) can charge and synchronize.
I have to say that I was particularly interested in the speed of the connected hard drives and the charging current during the test. The card reader is a nice gadget that I take with me, as I have to read something from an SD card here and there, but external hard drives are almost always attached to my MacBook.
In both respects, the Egolggo/QacQoc Hub scores well, so I can list it here as a recommendation with a clear conscience. Of course there would be another HDMI Connection was great because I need it for my external monitor, but then the hub would be a lot bigger and expensive again.
If you are interested in the device, you will find it here on amazon.
