Baseus 120W GaN charger review-fast charging without overheat

While other manufacturers took turns to launch typical 65W GaN chargers, Baseus launched a product using gallium nitride (GaN) and silicon carbide (SiC) technologies. And its maximum output power reached the amazing 120W. With 2C1A three-ports design, Type-C single port up to 100W fast charging, can it meet the needs of multiple simultaneous fast charging? Let’s check out Baseus 120W GaN charger review-fast charging without overheat.

The side is the introduction of key features:

  • Three ports can be used at the same time.
  • Gallium nitride + silicon carbide is used.
  • The output power is automatically and dynamically allocated.

Pull up and down to take out the inner box, which contains the charger, charging cable, a storage bag, product manual, warranty card and Baseus emoji stickers.

Appearance

Baseus 120W GaN charger is wrapped in frosted plastic paper, and there is an adhesive sticker on the output surface, corresponding to the identification interface, which protects the outer surface from scratches. The flat shape is easier to carry than the competitors.

The eye-catching 120W GaN word is lasered on the front panel, indicating that this product is a high-power product using gallium nitride. The lower part is the three output interfaces of 2C1A. The Type-C port is the mainstream choice that can output high power. The USB Type-A port of the orange tongue at the bottom indicates that it supports fast charging and has wide compatibility.

The three charging ports can simultaneously charge many devices including notebooks, tablets, mobile phones, cameras, drones, and watches. The double Type-C port adopts a blind plug design, so you don’t need to consider which plug is efficient when you use it, just plug it in at will.

On the back corresponding to the charging panel, there are the 220V pins. The remaining part is densely printed with the specific performance parameters of the product.

Baseus 120W GaN charger has a foldable storage design. So the charging pins are convenient to carry after storage. Put it in the luggage backpack to avoid scratching with other items.

Compared with the first generation 65W GaN charger, it uses the same family design. The interface panel still uses a stepped package design. Compared with the old model, the original light blue indicator is removed from the top of the side corner and replaced by Baseus Logo.

Size

After the measurement, the product size is approximately 94mmx55mmx30mm. It may be bigger than the general chargers, but as a high power output charger, it is acceptable.

Compared with the previous generation at the same time, the new 120W GaN charger has a long flat and narrow shape design. And the thickness is basically the same as the narrowest surface.

The height and width are larger than the old model. However, the flat and narrow shape has its outstanding advantages: On the one hand, it reduces the space occupied by the wall plug or the strip; On the other hand, it is convenient for storage when carrying.

Weight

Baseus 120W GaN charger weighs 217g. As a 120W product, this is an acceptable weight and it will not add too much load to travel.

Cable

The overall feel of the cable is moderately soft and hard. The measured wire diameter of the charging cable is about 3.5mm, and the length includes the total length of 109cm.

Tested by Power-Z kt002, the charging cable has an E-Marker chip that can transmit 5A current. So that it can deliver 100W of power with a capacity of 20v@5A. The measured cable resistance is about 105 milliohms, which is a low-resistance, high-quality cable that can efficiently charge the device.

Performance

Supported protocol

USB-A port

Use POWER-Z KT002 to test the USB-A port fast charge protocol. We can see that the USB-A port supports APPLE2.4A, QC2.0, QC3.0, Samsung AFC, Huawei FCP, SCP, PE+ fast charge protocol.

USB Type-C port

KT002 tests the C1 port, and the tester shows that the port supports QC4+, PD3.0 and PPS105W in addition to the fast charge protocol supported by the USB-A port.

PDO

By reading the message of the Type-C port, it has a complete PDO voltage. The five fixed voltages are: 5V / 9V / 12V / 15V @3A, 20V@5A, PPS support: 3.3-21V@5A. It means Baseus 120W GaN charger can charge almost all the devices.

Heat test

I used two constant loads to simulate high-power output. Because the temperature of the load meter is also very high, I am afraid of high temperature downtime, so I lowered the output power. The above picture is 40W and adjusted to 30W output.

The second channel is set to 70W, so the total is reduced from 110W to 100W, and the output continues for 50 minutes.

This is the temperature of the two load meters, which is more than 82° of 30W, which is a bit hot.

Although there is no 120W full power test, but the heat generation is somewhat unexpected. The high-power-density product is designed with dense internal stacking to reduce the size as much as possible. From the previous test of a variety of 65W GaN chargers, the actual test results are not ideal. The surface temperature is mostly around 70 degrees.

However, the highest temperature of Baseus 120W GaN charger is 66.3°, and the highest value at C1 port is 76.1°, which is lower than I expected. Of course, the lack of full load may also be a major reason. But the overall performance is still good.

The verdict

Baseus 120W GaN charger is compatible with a wide range of protocols, and solves the contradiction between fast charging requirements and multiple charging. At the same time, it supports the maximum output power of 120W, the single port supports up to 100W fast charging, and the dual Type-C ports support blind insertion and dynamic power adjustment strategies. The performance is sufficient for most usage scenarios.

Of course, it also has disadvantages, such as the high price, and big size. But it is still great for those who has the demand of a portable multi-ports fast charger.
