The parameters of radium carving on the charger shell are different from those on the carton packaging.

3 Output interface configuration

The charger of byaz 2c1a adopts a very rare horizontal and vertical arrangement, usb-a interface is placed horizontally, and two usb-c interfaces are vertically placed. It looks like a video pop screen website logo. In addition, some netizens laugh to call this arrangement zhoudongyu.

The charger output interface is captured by using a micro lens. Special contacts are visible at the front end of usb-a green tongue base. The two sides of the positive and negative shrapnel are widened to reduce the contact resistance to obtain more current.

4 Volume and power density

The size of the charger can be reduced by using Gan power device. Now, measure the size of the charger with micrometer of 76mm.

The width is 39mm.

The thickness is 34mm. According to the length, width, height and power, the power density of the charger is 0.64w / cm ³ The weight is 147.3g.

4 Compare with ordinary charger

  1. Comparison of multi port charger

The biaz Gan charger is designed with a bar column, which has a very close structure, and is smaller than the traditional multi port charger.

 

  1. Bar column design advantages

The most common scenario of charger is to use with the patch panel. The patch panel will be placed near the wall. The common charger has occupied a lot of space in front of it. The bar column design of the biz charger will not interfere with the space in front of it, and the desktop will be more tidy.

5 Basic parameter test

1USB-C1

Use power-z kt001 USB tester to read PDO message of usb-c1 interface. Usb-c1 interface has five fixed voltage ranges of 5v3a / 9v3a / 12v3a / 15v3a / 20v3.25a, and a set of PPS voltage 3.3-16v3a.

The fast charging protocol polling of usb-c1 does not support any common fast charging protocol.

2USB-C2

There are five fixed voltage ranges of 20v1.5a, and two sets of PPS voltage 3.3-11v3a / 3.3-16v2a.

The fast charging protocol polling of usb-c2 does not support any common fast charging protocol.

  1. Usb-a and usb-c are different. Usb-a output port support protocol is very rich, with apple2.4a, qc2.0, qc3.0, AFC, FCP and SCP, covering most of the brand fast charging protocols in the market. In addition, MTK PE fast charging is also supported in the later part of the measurement.

For usb-c1 and usb-c2, there is no common fast charging protocol. The small coder consulted the manufacturer. The manufacturer feedback that the current version is not the final version, and the subsequent version will be changed.

6 Compatibility simple test

1USB-C1

 

The iPhone 11 Pro Max supports the USB PD and apple2.4a fast charging protocol. Usb-c1 is used to charge the iPhone 11 Pro max with a power of 9.22v 2.51a 23.25w. The USB PD is successfully handshaked for fast charging and reaches the maximum fast charging power stage of USB PD.

 Apple Charger Cable

Xiaomi 9 supports USB Pd / QC / 27W chargeturbo fast charging protocol. It uses usb-c1 to charge Xiaomi 9, with power of 9.56v 2.52a 24.15w. It successfully handshakes chargeturbo to charge quickly and reaches the maximum stage of chargeturbo fast charging power.

 

Charging head network Summary:

 

The end of the evaluation of the biaz 2c1c 65W Gan charger is over. The power density reaches 0.64w / cm after using Gan power device ³ Compared with the traditional multi port charger, the bar column design will not occupy much space on the desktop patch board, and it is easier to go out and carry than the ordinary charger.

 

iPhone 12 charger

It has a high-power output of up to 65W and a multi port configuration with two usb-c and one usb-a, which can provide power for notebook, tablet, mobile phone and other digital devices at the same time, and take care of multi device users. Usb-c1 supports five complete voltage ranges of 5v3a / 9v3a / 12v3a / 15v3a / 20v3.25a max, and also has a set of PPS voltage 3.3-16v3a. Usb-c2 supports 5v3a / 9v3a / 12v2.5a / 15v2a / 20v1.5a max, with two additional PPS voltage 3.3-11v3a / 3.3-16v2a. Usb-a supports 4.5v5a / 5v4.5a / 9v2a / 12v2a output.

 

Both usb-c have PPS fast charging protocol in terms of fast charging protocol, which can provide fast charging for standard USB PD devices. The measured power of iphone11 Pro Max reaches 23W, supports 27W chargeturbo of Xiaomi and supports Meizu mtkpe. Common QC, AFC, FCP protocols are not supported. Usb-a interface fast charging protocol detects all green, and supports apple2.4a, QC, AFC, FCP, SCP and PE.

 

In terms of multi port strategy, usb-c1 supports 65W output at maximum when single interface output, which can provide high power charging for notebook. When usb-c1 + usb-c2 or usb-c1 + usb-a is output, 45W + 18W is available, and power is 45W + 5v3a when three ports 2c1a are output simultaneously. Users can flexibly match the choice between high power and multi equipment according to their own needs.

 

The voltage power is very stable in one hour full load test. The maximum heat treatment of the three surfaces of the shell is 66.4 degrees, 75.2 degrees and 70.8 degrees, and the overall heating is relatively uniform.

 

The above is the full content of the open box evaluation of the biaz 2c1c65w Gan charger. It is suitable for the user group with multiple equipment charging requirements for the volume requirements. Later, we will disassemble the charger, and see the Gan design. Interested partners should not miss it.
