  Hello Friends

  My uncle bought this laptop:

  Dell Inspiron Plus 16" Touchscreen Laptop - Intel Core Ultra 9 185H - 1920 x 1200 - Windows 11 - 32GB RAM - 2TB SSD

  Even when the laptop itself has the classic Power Jack (the cylinder) the Laptop Charger is USB Type C.

  Therefore

   

  Laptop Charger -----> (USB Type C) Laptop Yes

  Laptop Charger -----> (Power Jack) Laptop No

   

  The laptop charger has the following data

   

  Dell 100.0w AC Adapter

  Dell Output 5.0v --- 3.0A/15.0W,

              9.0v --- 3.0A/27.0w,

             15.0v --- 3.0A/45.0w,

             20.0v --- 5.0A/100.0w or

             12.0-20.0v---5.0A max./100w max

  INPUT 100-240v~1.7A 50-60Hz

  Model No Dell LA100PM220

   

  Thus practically is this one:

   

  Dell Laptop Charger 100W Watt USB Type C Thunderbolt 3 AC Power Adapter DA100PM220 LA100PM220 HA100PM220

   

  Because I am not an expert: we are assuming the Laptop must receive from the Charger 100W (Correct me if we are wrong)

   

  Now, the reason of this post. Because my uncle needs the USB-C port free for other uses, the option exists to buy this Docking Station:

   

  USB C Docking Station Dual HDMI Monitor,USB C to Dual HDMI Adapter with 2 HDMI Ports,PD Charging,SD/TF,USB A&C 3.0 Ports,USB C Hub HDMI for Dell XPS/HP/Lenovo/Surface/Yoga etc

   

  It has a lot of buys and a well amount of nice customer reviews

   

  The main concern and reason of this post

   

  Question;

  • Does this Docking Station really have an output  of 100w?

   

  First: If you see the 5th Figure of the Docking Station link, theoretically applies the following sequence:

   

  Dell Laptop Charger (100w) ----> Docking (100w) ----> Laptop

   

  Thus theoretically, is it safe buy the docking station to be used for the laptop?

   

  Second: but in the Docking Station link it says:

   

  • [Speedy charging 100W] This dual hdmi adapter for 2 monitors with a USB-C power delivery port(near the SD/TF) can charge your laptop anytime; hdmi hub for multiple monitors input 100W, output 87W. Please Note: Power charger & charging cable is not included in the package. Note:The second USB C port is only for data transfer.

   

  As you can see it does mention of 87w. So I'm confused if the output is 100w or 87w ?

   

  Third: About the italic part, there fits the original Dell Laptop Charger

  Fourth: the other reason to buy this docking station is use in parallel 2 Monitors through HDMI

   

  Therefore the expected functions and goals by the Docking are:

   

  1. Serve as a bridge between the Dell Laptop Charger to the Laptop to deliver 100w as output
  2. Connect 2 HDMI monitors at the same time

   

  But we need an explicit confirmation for the first point

   

  Thanks for your understanding

  Hi @Manuel Jordan ，
  
  

  The PD charging port on the Hub supports a maximum charging power of 100W. Since the Hub itself needs power to work, a portion of the power will be deducted, about 13-15W, and then transmitted to the computer.

  So when the charger provides 100W power to the Hub, after deducting a portion of the power of 13W, the actual power transmitted to the laptop is about 87W.

  Hi @Manuel Jordan 

  1. The hub's PD port supports connecting up to 100W of PD power, because the hub will withhold about 15W of power, computer will be able to receive about 85W of power if a 100W PDpower supply is connected.Rest assured that the connection "PD power supply ---->hub ---->laptop" is safe.

  2. The power supply you linked is an AC power supply, which is not compatible with our hub, which are only compatible with PD power supplies that support the PD protocol.Do you have any other power supplies that support the PD protocol?If you're not sure if power supply supports PD protocol, please let me know the model number of your power supply or take a picture of the label on the power supply and send it to me, I'll confirm if it supports the PD protocol.

  3. After check, your laptop is compatible with the hub, so it supports connecting wo monitors through two HDMI ports.

  Hello Selore

  Huge thanks for the replies. I appreciate your quick and polite information

   

  The PD charging port on the Hub supports a maximum charging power of 100W. Since the Hub itself needs power to work, a portion of the power will be deducted, about 13-15W, and then transmitted to the computer.

  So when the charger provides 100W power to the Hub, after deducting a portion of the power of 13W, the actual power transmitted to the laptop is about 87W.

  Ok, it is absolutely clear

  1. The hub's PD port supports connecting up to 100W of PD power, because the hub will withhold about 15W of power, computer will be able to receive about 85W of power if a 100W PDpower supply is connected

  Ok, it is a reconfirmation of the previous reply. Ok is clear the relation about: input (100w) ---> internal consumption (15w) ---> output (85w)

  Rest assured that the connection "PD power supply ---->hub ---->laptop" is safe.

  It is the main concern, because if the laptop expects an input of 100w.

  • Question1:How is safe for the laptop if it receives 85w instead of 100w?

  Furthermore if the laptop can work in peace with 85w.

  Question2: Why from the beginning the original Dell Laptop charger is not built to bring an output of 85w?

  2. The power supply you linked is an AC power supply, which is not compatible with our hub, which are only compatible with PD power supplies that support the PD protocol

   

  Question3: Pls, could you expand the idea?

  The AC Power supply has the USB-C connector and according with the Figure of your product the input is through a USB-C port. Therefore theoretically the connection is possible 

  Do you have any other power supplies that support the PD protocol?

  No, but as a reminder the goal is to accomplish the following goals with the Docking station:

  • To use it as a bridge between the original Dell Laptop charger and the laptop itself
  • To use the 2 HDMI ports to connect and use at real time two monitors at parallel

  If you're not sure if power supply supports PD protocol, please let me know the model number of your power supply or take a picture of the label on the power supply and send it to me, I'll confirm if it supports the PD protocol.

  Understood, it is as follows:

  

   I'll confirm if it supports the PD protocol.

  Huge thanks in advance

  3. After check, your laptop is compatible with the hub, so it supports connecting wo monitors through two HDMI ports.

  Sounds great, remember my concern about the difference 15w

  Pls, answer the 3 questions

  Thanks in advance

  Hi @Manuel Jordan

  1. If your computer power is 85W, then charging the computer through our docking station will consume 15W, leaving only 70W of power to the computer, and it is definitely safe, please feel free to use it.

  2. Regarding your statement that the Dell laptop charger does not provide 85W output, this depends on your charger, and we have no way of knowing.

  3. According to your picture, the charger in your picture is PD protocol. If you use this charger to connect our docking station, it can charge the computer.
  
  4. Your computer is compatible with our docking station, so you can use the 2 HDMI of this docking station to connect two monitors.
