In the test: Hunda A1903 Multi-Port 2A2C USB power supply with 150 watts

In the test: Hunda A1903 USB PD power supply

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.

Transparency notice

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”.

Competition: a power supply unit will be raffled off

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.

Update 13.1.2021: Purchase via Huwder.com

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.

If you want to order the power supply from Huwder, please go via this link and enter the code "JensCoupon2021" at the checkout.

Special features of the Hunda USB C power supply

There are a few points that should be positively noted in advance:

  • The power supply comes with grounding (which is extremely rare with USB power supplies) and thus offers increased security against the risk of touching a live part if the housing should be opened (through damage or intent).
  • Both USB C ports have equal rights and can each individually deliver up to 100 watts of output power. If both are used, they can each emit a maximum of 60 watts, but together only a maximum of 100 watts.
  • You can actually charge two MacBook Pro models with the power-guzzling Intel chips with it and it is hardly slower than with the Apple power supply, which can only charge one device.
  • You can use the power supply both standing and lying down. The plastic stand is removable and the underside of the stand and power supply unit have anti-slip protection.
The low standby power consumption of 0,3 watts is nothing special in this sense, but a nice addition that further enhances the power supply.

Design and workmanship

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.

On the back of the USB PD charger you will find the technical data printed again and you can see the three-pin socket including grounding.

My tests with MacBook Pro (15 inch, Intel), iPad Pro and iPhone 12 Pro Max

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:

Measurements with individual 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.

I processed the Hunda power supply with all available APple devices and also with USB load resistors, but only good properties came out of it.

All USB C ports and all USB A ports are the same

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.

My little MacBook 12 inch is charged with approx. 27 watts - just as fast as with the Apple power supply.

Measurement with MacBook Pro, MacBook, iPad Pro and iPhone at the same time

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.

Power distribution diagram depending on occupancy

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.

Here you can see how many watts you can get from which port depending on the occupancy.

Here you can see how many watts you can get from which port depending on the occupancy.

Can the Hunda A1903 also charge two 16-inch MacBook Pros at the same time?

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.

Important: Use of 100W USB C cables

If you want to use the full power of the USB-C ports, you should make sure that you only work with USB-C cables, which can also transfer 100 watts via USB Power Delivery. In my hodgepodge of cables I have some that can ONLY be used for charging and others that transmit minimal power while charging, but offer high data throughput for data transmission. The problem: You can't tell by looking at the cables, because they all have USB-C plugs on the front and back and fit into the corresponding sockets. For this reason, at some point I started buying multiple USB-C cables that can do EVERYTHING: charging and data transfer. So I always have the certainty that I have the "right" cable to 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:

So far, I've only had good experiences with CableTex cables: top performance when charging and high transfer rates when used on hard drives or other devices with data throughput.

My conclusion on the Hunda A1903 USB-C / A multiport power supply

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.

    Hello, Jens!
    If there was still an alternative:
    LinkOn Ganius 166W from AMAZON

    • Jens Kleinholz says:

      Hello Volker! Thanks for the tip. I wrote LinkOn directly and asked for a test device. Let's see what they say ...: D

    • Jens Kleinholz says:

      Linkon sent me a test device, but unfortunately they packed the 136W model for me. With that, of course, I can only say something about the 166W model to a limited extent, but I'll still write a report on it soon. I think they are very similar in terms of technology.

  2. Volker says:

    Hello, Jens! It could be that there is a small white sticker on the bottom of the opening tab, which indicates that it is the 166 watt version, even though it says 136 watts on the box. I was also irritated at first.

  3. Volker says:

    Mmmh! But that's cheese. I wanted to order the Hunda too. But is currently not available. AMAZON also does not know when it will be available again. ????

    • Jens Kleinholz says:

      Hello Volker! I have good news for you. Hunda entered a coupon code for me so that my readers can order directly in their shop. The code is only valid for one power supply unit, but you even get free delivery to Germany and they wanted to take over customs. I've just tried it and end up with a price of around 45 EUR. Here is the link to their shop and this is the code for the 15 USD discount: "JensCoupon2021". I hope you can still get the power supply. : D

    Hello
    I have just read your test and ordered the A1903 with the code JensCoupon2021. I'm curious whether it will also come to the Netherlands without customs etc.🤔

    • Jens Kleinholz says:

      Hello Henk! First of all, thanks for the indirect support of my blog. I also hope it comes duty free. At least that's what the manufacturer promised. Please give me feedback on this! I still like to use the power supply. It does not whistle, does not get hot and diligently supplies power from all channels ... the way it should be. Good buy for the price.

  5. Still says:

    Hallo,

    I tested the device for a week from a friend who ordered it on Amazon through your review due to the shorter delivery time and I am thrilled. Of course, with reservations about the suitability in 1 year + long-term use, I have to say I am thrilled. The technology is unrivaled in Europe and at such a price (90 € on Amazon, 50 € through your code).

    Macbook, a cell phone and headphones can be charged and operated very quickly at the same time. Just lovely!

    Now I've got the 150W Hunda charger to replace my Macbook charger. Costs less than the original power supply and can do a lot more.

    However, I asked myself what the different names are all about: Huwder, Hunda, etc. is apparently the same technically and visually at first glance. Or are the names for different markets?

    In any case, I hope that the device is as good as what I have ordered myself with your code and will - if I don't forget it - report again.

    I think it's good when China can convince with high quality without any alternative!

    • Jens Kleinholz says:

      Hello still! For me it still purrs like on the first day. And I've already tormented it a lot. : D I also approached the manufacturer about the different names and he told me that Hunda is a Huwder brand (or vice versa, I don't know 100% anymore). So basically everything is the same technology, just a different logo on the case. LG, Jens
