In this project I will show you how to create a Laptop PowerBank. It mainly consists of a Li-Ion battery pack and one buck and boost converter. This way the PowerBank can get charged up through the Laptop power supply and aftewards charge up the Laptop directly to give it an additional run time of 3 hours. Let's get started!

Step 1: Watch the Video!

The video gives you all the information for a basic overview of the project. During the next steps, I will present you more detailed information.

Step 2: Order Your Components!

Step 3: 3D Print the Enclosure!

Here you can find the 123D files as well as the .stl files for my enclosure. But make sure that you also print the corrected lid file which is 5mm longer.

Step 4: Do the Wiring!

Here you can find the wiring schematic along with tons of reference pictures of my laptop powerbank. Feel free to use them to create your own powerbank.

Step 5: Success!

You did it! You just created your own Laptop PowerBank!

    Since I am not a EE, I am looking for one who can create a PCB for my powerbank with nand chip on it for prototyping. I know I can order such pcb's from China for powerbanks but I need an extra function on my device for storage. the measurement of such pcb would be around 150mm/200mm by 1000mm (see pic as a format), double or triple layers. I have a small budget can pay you but let me know your rate.

    a better solution would be to increase the laptop battery

    That's a great project. I'm happy to see you included all the safety measures in it.
    I had the same problem of less working time out of my old laptop battery. So I got a new battery and now if the battery dies, I can hibernate the laptop(it auto hibernate when battery level drops), switch out the battery and continue working. Much simpler method but yours is much cooler :)

    Have a look on AliExpress, you can save a few bucks at least. I did a quick search for an 8s 24v BMS, and saw a few listed over there.
