With 20V PD laptops getting more and more, PLEASE do a video about a DIY 45W/65W PD power bank. Commercial PD powerbanks for those (in my case a Thinkpad L390Y) are still rather expensive. And in my opinion this new capability of also charging laptops is the true advantage of USB Type C. Fast charge for phones is nice, but not needed. Having a power bank for your laptop is just a new, really useful class of mobile charging
I agree. Not sure why there are no DIY versions? Patents, proprietary laptops making a universal BMS impossible - no clue - anyone? Also wondering if laptop batteries are 10.6V why can't power banks with usb-c power delivery also be 10.6V or 3S2P battery packs, help?

Very smart decision GreatScott. That is an excellent board you found. I put together a simple 5 volt portable power bank using an attiny85, a 2S bms, buck converter all connected via a custom jlcpcb board. It was a lot of work. You are much smarter than me.
According to the design, the connecters on the board is made with a little space in front of the plugs. It means that you could easily have some material in the front to hide the pcb screws and the pcb itself and still connect the plugs as they are supposed to.
I was so impressed with this powerbank bord I BoughtOne and build a power bank is it been using it for awhile now absolutely fantastic thanks for the recommendation and also very cheap from AliExpress
Nice, I would love to see a similar project with, 12V IN and 12V-24V regulated output (maybe USB as well) and several cell in Series (with a proper BMS and protections)
To hear you spent 3 hours searching for the right IC makes me feel better about myself. I spend like 2-3 hours for just about each IC I use in a project. And I spend another 3 hours just to find the right passive components at times…
Nice video as always ! I recommend to use recess in your 3d printed housing, so the parts will connect better with fitting into each other, then you will get the joinig surface smooth, and and also stronger.

@GreatScott Really a nice small project. A small power bank story. I visited Fare East via Beijing and had one simple 1 cell power bank with including LED torch (from ebay) and a 3 cell powerbank made by FSP in my board case. At airport you have to put all electronic device out of the case for scanning. Because the nice 1 cell powerbank with torch had no label with voltage and energy information on it the security people take it away. I explained them that this small powerbank will only have 30% of the FSP and that there should be no risk. But there was no chance to get it back. So if you fly (to Beijing) do not forget to put a label with voltage and Wh on it! Otherwise security people will maybe confiscate it.
Wouldn't it be more efficient and more robust to run the 18650's in series, with a BMS to balance their charge, and use a switchable buck to produce the 3 USB-C charging voltages? I hate running 18650's in parallel ever since the Great Workbench Fire of aught-18.
I am following you for a long time and i like your Electronic Basics series of videos which helped me a lot, try to make that kind of video and new electronics concepts.
Hey, thanks for the info about that PCB, was exactly what I was looking for! But the next step: adding an integrated solar panel?? Show us the way master! 👍

This is perfect! I hate buying battery packs & not knowing what is inside. There is no need to balance the cells? How about DIY battery packs for power tools? Is there a similar board?
I have a 24V bixpower with all the BMS in built. But I'd like an easy way to add one usb c PD for 20V use, a second one for 12V, then a couple of 5V USB A. The above kind of pcb would be perfect if it only could take 20-30V input! Feels weird having a separate 24V to 3.7V converter first and don't know how I could get 20V 60w usb c PD out of it then?
It is no issue to mix and match cells as long as they go in parallel. As for different voltage levels, equalise the cells with a lamp or resistor between them. Not a problem :)
Nice video, and great explanation as always! Keep up the good work! PS: finally you hide those screws into the housing! Its much more polished looking :)

Just wondering. Didn’t you attach „temperature meter“ to switch off charging procedure, when 18650 gets too hot?

I don't see any Programmable Power Delivery support, which is nice if you want specific voltages, such as 8V for a camera.
I have to say It is ok to use diffrent type with diffrent capacity battery in parallel.just make sure they have same voltage level when connct them together

How about a circuit that actually support the 100w (20v 5a) that a type C connector is allowed to support.

can deliver 3.1A, but at 3.98 volts?
