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 charger needs to be Pro: Baseus 65W GaN 2 Pro charger evaluation 43

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.

The charger needs to be Pro: Baseus 65W GaN 2 Pro charger evaluation 44

One hour later, the current maximum temperature is 74.7℃, which is relatively uniform overall, and the temperature has risen by 44.8℃.

The charger needs to be Pro: Baseus 65W GaN 2 Pro charger evaluation 45

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

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.
