Chapter in this post:
I have already tested a few multiport power supplies, but this Hunda A1903 tops all in terms of output power. With two USB-C PD ports and two USB-A ports (therefore 2C2A) it can supply four devices with power. The maximum output of 150 watts ensures that even the large Intel MacBook Pro models with 15 and 16 inches can be charged in pairs.
Hunda provided me with the USB C power supply free of charge. However, the test ran without their influence and without specifications. So you're reading my honest opinion and not a “bought advertorial”.
Hunda has provided me with an additional copy of the A1903 charger that I will be giving away in my newsletter over the next few weeks. If you want to participate, you should register thereso that he can hear the question about the prize or the raffle. And I can already reveal: It's worth it, because the power supply is really convincing.
I received an email from the manufacturer Hunda in which they said they were very pleased with my item. To do my readers a favor, they set up a discount code that will deduct $ 15 from your power adapter order and back my blog with $ 5.
They also take care of customs and shipping costs to Germany, so that you end up with a price of 55 USD. I have just tried this and you actually get this total, which is around 45 euros. This is significantly cheaper than at Amazon.

There are a few points that should be positively noted in advance:
To speak of “design” when referring to a power supply unit always sounds a bit exaggerated. Indeed, the Hunda A1903 certainly didn't spend too much money on the design. The power supply is optically completely ok and does not stand out, but it is also not particularly ugly. However, the two "splashes of color" green and orange are well placed because they are inside the USB A and USB C sockets, so that you can quickly see where the respective charging cable has to be plugged into. That sounds like a minor matter, but I have often had to use the iPhone flashlight in a dim room to see where the socket is hidden in a power supply.
I think the workmanship is very high quality. In addition to the fact that it comes with a 3-pin power plug with grounding, which is an unusual but welcome safety feature in a USB power supply unit, it also seems to be technically very well constructed. I have this statement among others chinese blog post taken, in which the device was also dismantled in order to check the electronic components used and the entire structure of the power supply unit.
Of course, I also carried out my own measurements again to see how the charger performs with the usual Apple laptops, tablets and smartphones.
I used these devices:
To check each port, I only used one port and left the others free. Of course, my 15-inch MacBook Pro required the highest performance and was sometimes over 80 watts (peak value). However, this value was only retrieved because I had the MacBook Pro pretty empty and still with it while it was charging Geekbench tormented the CPU. If, on the other hand, the MacBook Pro is in standby and closed, it charges with values of around 50 watts.
I couldn't check the USB C ports for maximum power, because I don't have a consumer or load resistor that would use 100 watts. In the test report mentioned above, however, a charging power of 99 to 102 watts was confirmed by measurements.
On the other hand, I was able to test the USB A ports with a USB load resistor. Here the power went up to over 15 watts, but then I had to turn down the current flow through the resistor because the load resistor got too hot. The power supply could easily have delivered more power. According to the technical data, each of the two ports can output 22,5 watts.
When it comes to multiport power supplies, it is always interesting what they do when all ports are occupied. For example, some other chargers only have a single powerful USB C port, while the other provides significantly less power. As a user, you always have to remember which port should be used for the MacBook Pro and which for smaller consumers, such as the iPad or iPhone. Of course, this is not suitable for everyday use.
This is not the case with the Hunda A1903. Both the USB A and the USB C ports have the same technical structure, which means that you cannot accidentally charge the MacBook Pro at the "weak" port and it will not fill up despite a long wait.
From my point of view, this is very user-friendly: You don't have to worry about which port you plug your MacBook, iPad or iPhone into and the devices are always charged at the maximum possible speed.
In my measurements with the USB load resistors an important point is always lost, namely checking whether the ports switch off in the meantime and start charging again. This is for example my last one Test with a Ugreen power supply this was the case in a certain constellation and I only noticed it when a reader pointed it out to me (thanks, for that!).
This behavior of power supplies is very annoying, because every few seconds the iPhone, iPad or MacBook are giving the bling of that signals that they are now starting to charge.
So I plugged a MacBook Pro, a MacBook 12 inch, an iPad Pro and an iPhone into the various ports and waited over an hour to see what happened. The result: All devices are happily charging and the charging process has not been interrupted for any of them.
Since it is often not entirely clear how the power is distributed to the different ports of the power supply, I have a diagram for you (stolen from the Amazon site) that shows when, where and how much power is available. An X means that the port is unused.
Yes, it definitely can, but it will run a little slower than two Apple power supplies, which together can deliver almost 200 watts. The MacBook Pro 16 inch actually uses more than 90 watts of power at peaks, so that it has to hang on the lander longer with the maximum possible 60 watts per port (with double occupancy). As already mentioned, my 15-inch MacBook Pro only uses around 50 watts most of the time, so I assume that the 16-inch MacBook Pro only uses slightly more power and is therefore charged fairly quickly even in a double pack on the Hunda power supply.
With the current Apple Silicon MacBook Pro models, you don't have to worry about the loading speed. Even when used with an almost empty battery, they only need a maximum of 30 watts for operation including charging. This means that the Hunda could charge four of these laptops without sacrificing speed if there were a USB-C connector.
If you want to use the full performance of the USB-C ports, you should make sure that you only work with USB-C cables that have USB Power Delivery can also transmit 100 watts. In my hodgepodge of cables I have some that can ONLY be used for charging and others that transmit minimal power when charging but offer high data throughput when transferring data. The problem: You can't tell by looking at the cables, because they all have USB-C plugs at the front and back and fit into the corresponding sockets. Because of this, I ended up buying multiple USB-C cables that do EVERYTHING: charging and data transfer. So I always have the certainty that I have the "right" cable at hand.
The USB-C cables from CableTex have proven themselves for me. They are suitable for charging, for connecting monitors, hard drives or other peripheral devices and the workmanship is very good. The clearly visible print on the plugs also shows me directly that this is one of my all-round USB-C cables. The strings are braided and available in various lengths from Amazon:
It is not often the case that in principle I have nothing to complain about. With the Hunda power supply, I would actually only want 5 USB-C ports and maybe 5 USB-A ports. But the technology is not there yet. ????
Seriously: The power supply is robust, works flawlessly and delivers power through all ports that I have never seen anywhere else. Anyone who has to supply several MacBooks as well as iPads and iPhones (or other devices) with power via USB will certainly not make a mistake with the Hunda A1903.
The heat development was not very high when the four ports were fully occupied, so that, in my opinion, the charger can even be used in one cable box could accommodate, where the heat dissipation is significantly reduced.
The fact that there is no "loading, unloading, loading etc. problem" with the Apple devices when it has to charge several of them is a plus point. Otherwise it would not have been recommended in this review.
If you want to see or order the Hunda A1903 2C2A power supply, you will find it here at Amazon.
So that you can also take a look at the instructions or the printed technical data, I have photographed the enclosed instructions here.
