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?

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
Your descriptions of your journey is great. Love to show your notes and and diagrams to students. It is a great example of documenting your process. You don’t need fancy tools for documenting your ideas. Well done.
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.
And for those of us that dont have a 3D Printer, DIY Powerbanks on Amazon worked for me! USB Cable quality matters, when testing this can be important. And YAY we have the same USB Tester, wooo hooo!
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)
@KeeganDitty of course, I knew that already. But just look at how intelligently he uses his visual space, subliminal and all. One bright cookie, methinks!!!
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.
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…
Very interesting video, thank you! Are you sure it can output 3.1 A @ 5 V? Because there is a visible voltage drop to 4 V in video, when applying load of 3.1 A.
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.
now that PD 3.1 is out i really think you should build a USB C Ebike battery you can charge with USB C. No one seems interested in this but charging your phone your bike everything with one usb 3.1 charger is basically the dream. One cable to rule them all.
I was just looking for this type of pcb to make my own qc 2.0/3.0 power bank your video appear exactly at the good moment!! Thank you!👍👍👍👍Your the best!
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
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.

@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.
hi, thanks for such another great video. i have a question about at 7:56, is there any difference if you charge power bank with 5 v 2 A or 12 V 1 A how efficience change? for example i try this with my phone whenever I charge my Phone with 5 V 1.5A till %70 at night battery level down about %66, but whenever I charge with 9 V 1.8 A till %70 I saw %52 at morning.. is Fast charging really fill battery or just shows placebo effect us 🤔
This is a lot of efforts, well done. I might be wrong but this is not USB-C PD but Quick Charge 3.0...someone should please correct me if I'm wrong. Also, it is now possible to buy a ready-made QC 3.0 power bank case that can take up to 8x 18650 batteries.
I just bought a tablet that gives you a message stating it refuses to charge off of a standard USB so I can't use my battery pack :( the tablet only supports pd charging. The battery is powerful enough to charge the switch while it is playing a game like Splatoon and also is big enough to charge it 4 times so it should in theory be able to charge my tablet I just need to convert the circuitry to pd.
