In August last year, Baseus released the 1A2C 65W PD GaN charger, which has a slender and compact size on the basis of high-power and multi-interface output, and is highly sought after by users. While the iron is hot, Baseus has successively launched 45W, 120W and other multi-port GaN chargers, covering different user levels. After a year, Baseus has upgraded its most popular 65W GaN charger and launched the second generation Baseus 65W GaN2 Pro GaN charger.
Let’s take a look at whether this charger is “Pro” or not.
1. The appearance of the charger
Baseus 65W GaN2 Pro Gallium Nitride charger adopts a long square design with rounded corners on the four sides of the waist, which makes it easy to hold.
The charger uses a PC plastic shell, the surface of the fuselage has a matte texture, which is not easy to get fingerprints. The pins are also treated with piano paint, which makes the overall body have a contrasting color design.
The word “65W” is printed on the side, indicating that the charger supports up to 65W fast charging.
There are some introductions below:
Shenzhen Shishang Chuangzhan Technology Co., Ltd.
Manufacturer: Shenzhen Xiwei Technology Co., Ltd.
Made in China
The logo of GaN² Pro is particularly eye-catching, indicating its Pro identity
The charger has 2 USB-C, 1 USB-A, a total of 3 output ports, each port has a name silkscreen underneath, and a lightning logo above the three ports.
The USB-A tongue is orange, reminding the user that the charger is compatible with a special fast charging protocol, and we will test it later.
The charger also has a working indicator light. After power on, the indicator light will be icy blue light source, very beautiful.
The charger adopts foldable pins, which is very convenient for storage and carrying.
The technical parameters of the bottom screen printing charger are as follows:

Six, temperature rise test
Thanks to the successful mass production and commercialization of gallium nitride power devices, the miniaturization of high-power chargers has been realized, allowing consumers to enjoy this new era of technology. Many readers are very concerned about the heat generated by gallium nitride chargers, so we have added warm Rise test, but first of all, we must understand a few small knowledge about temperature rise test.
Charger heat is related to power density, efficiency value, internal design, ambient temperature, etc. Products with low power density are large and have enough space to separate the component layout, surface temperature will be lower, but the volume is often very large. For products with high power density, vertical plug-in component stacking is often used internally to make the charger as small as possible for users to carry. In theory, the temperature will be hotter than products with lower power density.
In addition, single-port chargers and multi-port chargers have different heat generation due to different circuit designs. Single-port chargers are AC to DC direct output mode, and multi-port chargers are AC to DC to DC, and the heat generation is relative after the secondary voltage drop. The single-port charger will be higher.
As a reference, in the one-hour full load test, the full load temperature of low-power density GaN chargers is generally between 60-70 degrees, while the high-power density single-port GaN chargers are generally around 70 degrees. The temperature of multi-port GaN chargers generally exceeds 70 degrees.
The temperature rise of Baseus’s new generation of 65W GaN charger was tested. The test condition was to conduct the test at a constant output of 20V 3.25A 65W for one hour in a thermostat with a temperature of about 25℃. Before starting the test, the maximum temperature is 29.9°C.
One hour later, the current maximum temperature is 74.7℃, which is relatively uniform overall, and the temperature has risen by 44.8℃.
Looking at the other side, the current maximum temperature is 74.9°C, and the temperature has risen by about 45°C.
Summary of temperature rise test
The one-hour full-load temperature rise link is used to test the heating of the charger under extreme use. Users rarely encounter such long-term full-load conditions in daily use. The power of digital devices such as mobile phones, tablets, and power banks is not large, and the temperature rise will be more moderate, while the charging of notebooks will reduce the power as the power is gradually saturated, and the heat will also decrease.
The current national standard requires that the surface temperature of the charger is not higher than 95 degrees. The maximum test temperature of Baseus’s new generation of 65W GaN charger is still much lower than the national standard. These temperatures are in line with safe use standards.
Seven, load test
1. Maximum output power
Use EB programmable electronic load to test the maximum output power of Baseus 65W GaN 2Pro charger, with 0.1A as the current step amplitude and 10 seconds as the time interval, the final recorded maximum output is 19.52V 3.60A 70.3W.
2. Full load stability
The stability test is carried out according to the rated power 20V 3.25A full load, the test time is one hour, the voltage value is horizontal and straight during the test, and there is no obvious fluctuation, and the full load is also very stable for a long time.
Eight, charging test
Baseus 65W GaN 2 Pro charger supports a maximum power output of 65W, with two USB-C output ports and one USB-A output port. When the USB-C1 and any interface are output at the same time, it is a fast charge output, so the editor simulates the daily use to test the charging process of the charger while outputting the notebook and a mobile phone.
Use USB-C1 to charge MacBook Pro 13. At the beginning, after a wave of current fluctuations, the 20V 2.25A charging gear was shaken. About 44 minutes ago, the voltage, current, and power platform were in a stable input state; then the power and current began to appear stepped After 1 hour and 15 minutes, the current is in the 1.5A input gear, and the power is about 20W; after 1 hour and 44 minutes, the power decreases with the gradual decrease of the current until the end of charging, the intermediate current rises briefly, and the whole process is consumed It takes about 2 hours and 23 minutes, and the highest power is 20.12V 2.19A 44.12W.
Next, let’s take a look at the USB-C2 charging the iPhone 11 Pro. After a short shock of booting, we shook hands with the 9V 2A input gear. After the three data platforms maintained for about 17 minutes, the current began to drop, and the voltage dropped after 52 minutes. To the 5V slow charging state, the power and current will gradually decrease after 1 hour and 10 minutes until the end of the charge. The whole process takes about 2 hours, and the highest power is 9.12V 1.99A 18.18W.

Summary of charging head network
Baseus 65W GaN GaN 2 Pro charger is the second-generation 65W multi-port GaN product of Baseus. Its appearance follows the family ID design. Both the inside and outside have been redesigned. The compact size is equipped with a new heat dissipation process and BPSII charging technology. And the volume is further reduced.
As a classic 2C1A 65W charger, the old version of the two PD interface output power configuration is 65W, 30W is a large and small power solution, the user may not get the best charging performance if the wrong interface is inserted. The two PD output ports of Baseus GaN2 Pro gallium nitride charger are replaced with mainstream power blind plug solutions. Type-C1 and Type-C2 can be inserted into one of them to obtain a maximum of 65W PD fast charge output. Users do not need to learn to use it at will The experience is better.
The volume has also been upgraded. Baseus GaN2 Pro GaN charger has a measurement size of 70mm * 36mm * 32mm. Compared with the old version, the length has been reduced from 75mm to 70mm, and the power density has been increased to 0.80W/cm³, reaching the current mainstream level.
The charger also has a rich fast charging protocol. The Baseus GaN2 Pro GaN charger is the same. It has 4.5V5A / 5V4.5A / 9V3A / 12V3A / 15V3A / 20V3.25A and other output voltage files, and supports PD3.0, PD2 .0, 5A PPS, QC3.0, QC2.0, SCP, FCP, AFC, PE, APPLE2.4 and other common fast charging protocols on the market.
In general, this is a very sincere upgrade. The family appearance, powerful performance, unparalleled compatibility, and small size are enough to become my favorite.
