When you use it , you maybe have these doubts or meet some problems.

Follow us to answer the question what your doubts and solved the problems that your meet.

1.When the product is in single-port use, it supports Switch full-state charging (including TV mode)；

When the two ports are used at the same time, if the Switch is in TV mode (the base is connected to the video), charging is not supported.

The Reason are as follows:

When the Switch is in TV mode, the system protocol needs to recognize the power ≥ 39W (15V/2.6A) to support charging.And For dual port output, the output protocol is 35+5/20+20/27+12/25+15, none of which can meet the requirements.

2.When the two ports charge the mobile phone/ipad device at the same time, you maybe will meet these problems.

A: For Samsung S21/S22/NOTE 20+Iphone 8 and iphon8 above version, the output protocol is 27W+12W；This situation cannot provide PD20W+PD20W.

B:After 2017 ipad+Iphone 8 and iphone8 above version, the output protocol is 27W+12W;This situation cannot provide PD20W+PD20W.

The Reason are as follows:

The firmware will give priority to providing maximum power charging to the device inserted first, and the output protocol has 20+20/27+12/25+15 output interference at the same time,and it will causes insert the phone of iPhone 8 and iPhone 8 above version,only can provide 12W (5V/2.4A) charging.

If the problem you meet is that the Apple mobile phones charge slowly, you can plug in the Apple mobile phone first, and then plug in the Samsung mobile phone/iPad, which can provide PD20+PD20 charging.

3.Windows+Windows notebook charging;There are the following states

A: First insert the notebook to support PD35W (20V/1.75A), then insert the notebook to support PD5W (5V/1A) charging.

B: Plug in the laptop first to support PD35W (20V/1.75A) charging, then plug in the laptop does not support charging or plug in the laptop first does not support charging, then plug in the laptop to support PD35WPD35W (20V/1.75A) charging.

C: Both Windows notebooks do not support charging.

The Reason are as follows:

a.The output firmware will give priority to providing maximum power charging to the device that is inserted first, resulting in an output allocation of 35+5W.

b.The early windows notebook system can only recognize PD20V, but cannot recognize handshake PD 5V, 9V, 12V, 15V, resulting in failure to charge.

c.In the early period of DELL, some models of Lenovo notebook systems need to determine that the PD power is ≥ 45W before they can support charging.

4.Windows notebook+Apple notebook charging;There are the following states:

A: Insert the Apple notebook first, and then insert the Windows notebook, the output distribution is PD20W+PD20W

B: Insert the Apple notebook first, and then insert the Windows notebook, the output distribution is PD35W+PD5W, Windows does not support charging

C: Insert the Windows notebook first, and then insert the Apple notebook, the output distribution is PD35W+PD5W

5: The concept of Apple mobile phone fast charging means that when the Apple mobile phone is at zero power, it can be charged from 0% to more than 50% in the first 30 minutes.It can be charged to more than 80% in 60 minutes;And when the power of the Apple mobile phone (iphone 8 and iPhone 8 above version) is about 80%, the Apple mobile phone does not support PD 9V charging.It can only support about 5V/1A charging, so it takes a long time to fully charge 80%-100%.

6: When using a third-party C-lighting data cable with MFI certification, there is a certain probability that the voltage cannot be boosted to 9V for charging.

The reason is that the third party has an MFI-certified C-lighting data cable, and there is a difference between the MFI chip and Apple's original chip, which causes the Apple mobile phone and the charger to be disconnected.

The protocol handshake failed, and the voltage cannot be boosted to 9V for charging.

Solution: Please plug and unplug the C head or lighting head of the C-Lighting data cable to rule out the abnormality.

7: Samsung S20/21/22 and Note 20 support PPS 25W protocol super fast charging

In theory, Samsung S10/Note 10 also supports PPS 25W super fast charging, but after the system upgrade of these two mobile phones, it appears that they do not support PPS25W; they can only charge around PPS18W.

8: This product does not support Samsung S8/S8+/S9/S9+/note 8/note 9 PD 9V charging, only supports 5V/3A charging.

The reason is that the Samsung mobile phone power management system requires that the PD protocol 5V is a non-standard PD protocol (not 5V/3A), and the mobile phone can support PD 9V charging.

Due to the low acceptance of non-standard PD protocols in the Japanese market, in order to avoid customer complaints, the 5V of this product adopts the standard PD protocol (5V/3A)

Noted: The above Samsung mobile phones use 5V/3A charging, and the mobile phones also display fast charging, and the full charging time is consistent with the 9V/1.63A full charging time.

9: When the dual ports are charging at the same time, some devices may automatically reconnect after a power outage.

Noted: When the mainstream devices on the market, such as iphone, ipad, Samsung and other devices are used at the same time, there will be no reconnection after power failure.

For automatic reconnection after power failure, it is a normal phenomenon that the agreement re-shake.

10: The charging power of the device is low, and the power does not reach the standard PD40W/PPS25W/PD20W/12W.

The reasons are as follows：

A: The nominal power on the charger is calculated based on the standard voltage * nominal current, as follows

PD40W=20V*2A; PPS 25W=9V*2.77A; PD20W=9V*2.22A 12W=5V*2.4A

B: When actually charging the device, the charging voltage is far lower than the standard 20V/15V/12V/9V/5V due to problems such as data line power consumption and terminal contact;At the same time, the charging current is lower than the rated value due to problems such as the high power of the device or aging of the battery cell due to long service life;

Based on the above problems, the charging power is lower than the nominal value.

11: When this product outputs 5V, the LED light color is green, when any port output is 9V/12V/15V/20V, the LED light turns blue.

12: When this product is charging a DELL or LENOVO notebook, the notebook battery symbol will display an exclamation mark, and the system will send a slow charging notification.

The reason is that the DELL or LENOVO notebook system needs to shake hands to identify the PD charger ≥ 65W protocol, it will be judged as normal charging; This product have no security risk and can be used normally.

13: When the product is charging a notebook, except Macbook Air (30W charging before 2022) on the market can meet full-speed charging, the rest of the notebooks that can support PD charging can only store power (if you use it while charging, Due to the charging rate is lower than the discharging rate, causing the notebook to shut down).

14: The C port does not support charging for gaming notebooks above 15.6 inches (except for Apple notebooks) on the market.

The reason is that after the gamebook is started, the power consumption reaches more than 100W, and the PD Charger (including PD3.1 140W) currently on sale cannot meet the usage requirements, and the system does not open the PD charging permission.

15: Some brand terminal devices on the market (such as the first/second generation Airpods, first/second generation IQOO electronic cigarettes, audio, TWS and other products) have a C-port charging interface, but they do not support PD charger charging.

Reason: When the PD charger is not plugged into the device, it is in a dormant state and requires hardware/firmware activation to charge.

The above devices (such as the first/second generation Airpods, the first/second generation IQOO e-cigarettes, audio, TWS, etc.) were not designed.

Consider the PD charging problem (the original charging is USBA), which does not include firmware/hardware activation, so charging is not supported.

Solution: If you have a C-USBA (as shown below) transfer, you can insert the C-USBA into the PD charger to activate it, and then connect the USBA data cable to charge the device.

16: Samsung series mobile phones have higher requirements for C-C data line loss. When the data line loss is large, it will fail to charge or switch back and forth between slow charging and fast charging repeatedly.

Solution: Replace the C-C data cable  

17: Samsung's early mobile phones/tablets are equipped with QC2.0/3.0 chargers, and the wiring is a USBA cable, so the original cable does not support PD charger charging, and needs to be replaced with a C-C data cable for charging.

18: Apple mobile phones before 2017, the original assembly line is USBA-lighting, so the original line does not support PD charging and needs C-lighting charging.

Before 2015, Apple notebooks had a Magsafe interface, and it was necessary to purchase a third-party C-magsafe data cable to support charging.

19.The terminal device is disconnected after it is fully charged. The judgment authority is in the terminal device system and has nothing to do with the charger;

If it has not been disconnected after being fully charged, the reason is that the self-consumption of the terminal device is too large, resulting in the charging current being always greater than the shutdown current set by the terminal device system. This phenomenon is normal and there is no potential safety hazard.
