Ugreen 65W GaN: Review Charging With Great Potential

Ugreen 65W GaN: Review 2022. The relatively recent GaN technology has a number of undeniable advantages over the traditional silicon version of power cells for chargers and other power supplies. For the end user, this is expressed in a significantly increased power of chargers with a modest size and low natural heating during operation.

Ugreen has unveiled its version of the powerful charger with modern fast charging protocols and four ports. If you are interested, I suggest that you familiarize yourself with the CD224 model together.

To begin with, traditionally the characteristics:

Brand / Model: Ugreen CD224 or Ugreen 65W GaN

Input parameters: 100–240V ~ 50 / 60Hz 1.8A Max

Number of ports: 4 (3 * Type-C + 1 * USB-A)

Fast charging protocols including QC, PD: yes

Output characteristics of ports:

USB-C1: 5V / 3A 9V / 3A 12V / 3A 15V / 3A 20V / 3.25A 65W max

USB-C2: 5V / 3A 9V / 3A 12V / 3A 15V / 3A 20V / 3.25A 65W max

USB-C3: 5V / 3A 9V / 2A 12V / 1.5A 18W max

USB-A: 4.5V / 5A 5V / 4.5A 5V / 3A 9V / 2A 12V / 1.5A 22.5 W max

Total output power: 65W

Dimensions: 65 * 65 * 31.8mm

The charger can be equipped with a separate 1 or 2 meter cable with or without a chip, i.e. 1 meter at 60 W. In my case, this is exactly such a cable, which was in a separate package, as a bonus from the store they put a tie.

The cable and the tie are branded, with the name of the manufacturer and of good quality.

The design of Ugreen’s commercial packaging departed a bit from tradition — the green color disappeared, but a holographic inscription was added and the box still looks presentable.

The characteristics are indicated below, and the packaging itself is made in the form of a pencil case. The content and its organization leaves a pleasant impression.

Taking the device in hand, you understand that you are dealing with a solid, high-quality thing. Charging more than many others, but the design is very successful. The surface of the side faces has a tactile pattern / knurling, which is convenient and at the same time somehow elegant.

Manufacturer’s name on one side, the other is blank.

The bottom edge informs about the characteristics of the device.

The ports, each of which is signed, are located on the front edge.

Let’s compare the dimensions with other, simpler chargers.

There is more charging, but there are four ports, which means you can go on vacation, for example, and not drag a “zoo” of chargers with you, or you can organize an energy hub at home, collecting gadgets for charging in one place.

The most advanced charging ports are C1 and C2. They are the ones equipped with the PD 65 W protocol and individually can give that kind of power to your laptop. The complete list of protocols is impressive.

The attentive reader will note that the 20 Volt PD protocol is limited to only 3 Amperes. This stems from the cable, designed for 60 W and does not have a chip in its design. If in its place a 100W cable, I think we saw higher values.

The lowest voltage value that can be set in QC3.0 in this charge is 3.6 Volts, which is not common. Often this is 5 volts, here 3.6, which is fully consistent with the protocol.

The upper value is 20 Volts.

Unfortunately, due to the lack of a powerful load, I was not able to fully test the ports C1 and C2, and remove 65 W from one port. But 65 W charging is capable of delivering simultaneously to all four ports. I managed to do this, although not with test equipment.

To begin with, I ran the tests possible with my load, i.e. maximum up to 35 W.

At 5 and 9 volts set at the output and exceeding the declared current, the voltage remains within the specification for USB, i.e. there is a power reserve.

At 12 Volts and 3 Amperes, everything is just as good. Apparently there is also a stock, but everything is leveled by the use of a cable.

And at 20 Volts, I managed to load the port up to 1.7 Amperes. Then the load was simply turned off.

The second port is identical to the first and therefore we immediately go to port C3.

Here the PD protocol is not declared, but nevertheless their list is no less impressive.

And this port, even with a cable, demonstrates excellent load performance.

And with 12 volts set, it was possible to remove even more than the declared 18 watts — 20 watts. And for a long time.

Now the USB-A port.

The protocols here are the same as those of the C3 port, but the possibilities are different.

For this port, 4.5V5A, 5V5A (apparently for MTK PE) and 5V3A are declared. I managed to shoot 3.5 Amperes in QC.

And with 9 and 12 Volts installed, the charging completely surprised, demonstrating a fair amount of power — 31 W (THIRTY ONE !!!) at 9 Volts and 28 W at 12.

Those. where 9V2A is declared, in fact, we get 3.4 Amperes, where 12V1.5A is declared, we get 2.3 Amperes.

Everyone waited for the charging to disconnect from overcurrent or overheating, but it turns out that such increased obligations are not at all burdensome for her.

As befits all decent chargers, the Ugreen 65W GaN has algorithms for compensating the voltage drop with increasing load — in all cases, the electronics tries to raise the voltage when the current rises.

Well, in the final, I loaded all ports at the same time in an attempt to remove the total 65 watts.

There is no such amount of test equipment, but there are three power banks with Type-C ports that work for input / output. These batteries can be charged with a voltage of 9 Volts and a current of 2 Amperes, i.e. a total of 54 watts.

USB-A port loaded with test load LD35…

During the test, I checked whether fast protocols on ports C1, C2, C3 are reset when the next power bank is connected to the next port. No, the protocols are not reset, each power bank is charged with a current of 2 Amperes at 9 Volts. The USB-A port showed a slight drawdown, remaining within the specification, and managed to remove about 9 watts.

Those. in total, taking into account the participation of three cables, it was possible to remove about 63 W, which practically corresponds to the declared 65, obtained in production conditions on completely different equipment.

Not an unimportant fact — during the entire test, and this is several hours of charging the power banks, the charging behaved completely silently and remained only slightly warm.

Summing up, we can unequivocally say that GaN technology fully justifies its development, and charging Ugreen CD224 its cost. High output power, extremely low heating, the presence of four independent ports (which means the ability to charge a wide variety of devices, including laptops), equipping the charging with a large number of protection types make Ugreen 65W GaN a completely justified and successful purchase.
