Review and testing of the GaN charger Ugreen Nexode X 160W (model X762)

Ugreen chargers have been confidently holding high positions in the accessories market for several years in a row. For more than 4 years, I have been charging all my home devices only with a Ugreen charger and I have not had a single problem: all the batteries of the devices I used remained safe and sound, and their capacity has hardly changed. However, recently I have felt the need for a more powerful charger. The previous Ugreen charger gave a maximum power of 65W, which was sometimes not enough. It also has some problems with modern fast charging protocols and cannot provide maximum charging power for some devices.

In general, without thinking twice, I chose the new Ugreen Nexode X 160W GaN charger, which supports the PD 3.1 fast charging protocol. Other popular standards, such as the Samsung Super Fast Charger, are also stated in the description. I tested it a little and am now ready to share my impressions.

Video version of the review

First, let's get acquainted with the technical characteristics. Despite the fact that the model is called Ugreen Nexode X 160W, it can deliver 140W of power to one port using the Power Delivery 3.1 protocol. The maximum 160W can only be obtained with the simultaneous use of the first two ports. In general, depending on the power of consumers and their number, it automatically distributes the load on the ports. The charger is created using GaNInfinity technology, which ensures high efficiency and less heating compared to conventional “silicon” chargers. There is also Thermal Guard technology, i.e. protection from overheating and temperature control.

On the side of the box you can see all the supported operating modes. In general, we can say that the charger is capable of delivering voltage in the range of 5 – 28 V with a current of up to 5A.

In addition to the charger, the only thing you can find in the kit is user instructions. If you do not have a fast charging cable, you will need to buy one. Not every cable supports PD 3.1, so you may run into its limitation and not get the expected power. I already have the appropriate cable.

Don't rush to throw away the manual. It schematically describes what power you will get when using different ports simultaneously. I recommend you read it.

Now let's study the charger. The case is in the form of a parallelepiped, the surface is matte. The plastic is of high quality, in the center is the Ugreen logo. On the opposite side is the indication of the maximum power of 160W.

The charger has 4 ports, which can be divided into 2 groups: high-power (USB-C1, USB-C2) and standard-power (USB-C3, USB-A). It is better to use the upper ports for charging laptops, tablets and smartphones, and the lower ones for charging old devices and small items (headphones, watches, etc.). The first port outputs up to 140W, the second outputs up to 100W. The first and second can output up to 160W in total.

Technical information on the side of the case.

Despite its impressive power, the charger has relatively compact dimensions and fits easily into a small pocket of a laptop bag.

Although the dimensions have grown slightly compared to the old 65W version of the charger. But the dimensions have grown only by 10-15 percent, and the power has increased by 2.5 times.

But the weight has increased more significantly. If my old charger weighed only 174 grams, this one weighs 318 grams.

Now to the tests. First of all, I checked how the new charger would work with my Samsung Galaxy Tab S9 tablet. The old charger did not support Samsung Super Fast Charger and the maximum power was limited to 27W. I did not understand this right away and at first I blamed the tablet. The new charger turned on in the right mode from the start, and the power exceeded 40W.

The tablet itself supports up to 45W and at peak charging I saw numbers close to that. If you're interested, with the new charger the total time has decreased from 1 hour 49 minutes to 1 hour 10 minutes.

Let's complicate the task. The Ninkear A15 Plus laptop, which supports charging via USB-C. When traveling, it's convenient to take only one charger, rather than carrying a whole “zoo” with you. It will be for the laptop, the smartphone, and other small things.

Charging has switched to 19.6V and the total power has reached 60W.

The most powerful consumer I found at home is a portable charging station. It has the ability to charge via USB-C with support for the PD 3.1 protocol and a power of up to 100W.

The station has a built-in wattmeter and it shows 96W, my tester shows 95.867W. The readings match, the declared power is maintained.

I can't load it with anything at 140W. There's simply nothing to load it with. But I can check the total declared power at 160W, for which I'll connect the charging station and the laptop at the same time. And to see the total consumption, I use the Atorch smart socket with a wattmeter.

The charger can handle 2 powerful consumers without any problems, and the Atorch socket shows 177W (conversion losses).

Separately, the testers show the following values: 59.33W consumed by the laptop and 95.84W consumed by the charging station. In total, we get 155.17W.

I try to add a third consumer in the form of a power bank. The corresponding circuit is immediately switched on (it is indicated in the instructions) and the power on the first two ports drops to 65W, and the third one produces 30W. Total 160W.

The last thing I checked was heating. Having loaded the charger to the maximum (total consumption 155W), I waited half an hour and took a thermogram. The charger heated up to 62.3 degrees, the case felt quite hot to the touch (it was difficult to hold in your hand for a long time). At the same time, it did not smell of plastic and generally worked fine.

In the end, I am very pleased with the charger upgrade. I bought it mainly for my future reviews to test the charging speed of modern devices. Often, new tablets and smartphones are sold without chargers, and sometimes the laptop chargers that come with them cannot reveal the full potential of the device. My old 65W Ugreen charger was no longer enough and the first warning sign was last year with the Tab S9 tablet. Now I have a power reserve for several years and, most importantly, support for the latest charging standards, in particular PD 3.1. The Ugreen Nexode X 160W fully meets all the stated characteristics and I can confidently recommend it to those who are looking for a powerful but compact charger for laptops, smartphones and tablets.
