Hello everyone, this concludes this version of the power bank (which is open-source) I am currently planning to start a campaign, but it will most likely take 2-3 months(create a company, website, contact manufactures etc.). If you have any suggestions or advice, please comment below as I do read all of them. I will post major updates in the community tab. The next project should be a lot simpler. I thank all of you for your support!
Suggestion - Make potentiometer digitally selectable maybe with arduino...by this way we can avoid accidentally rotating the voltage knob and frying the charging device. Awesome work dude. Appreciate your time and dedication to the project.
I think it would be incredibly smart to sell a kit version of this since I believe a lot of your audience is DIY-inclined. With the offer of an electronics project and a cheaper price tag, I think you'll be able to sell even more than with just a complete product.
Definitely agreed I wanted to learn more about circuitry and electronics and building my own DIY project I feel like this would definitely help me learn more
I hope there is a "DIY Kit" level to back on whatever crowdsourcing site you use. A full set of the electronics ready to be assembled would be a fun gift. With or without the 3d printed parts.
This is next level stuff right here. Your powerbank projects are some of the coolest on the whole web. Your videos are awesome! I'd like to point out a couple of things... I'm not a hardware designer, but here's my two cents anyways: 1. I just finished watching part 1, one of the first things I noticed is that the print quality, while definetely acceptable for a DIY project, is definetely *_not_* acceptable for a final product. I suggest refining the exclosure print quality a lot before you start producing these on a larger scale. From what I see, it appears that you've already improved the case print quality quite a bit compared to the previous video, so that's definetely a step in the right direction. 2. There's a lot of assembly tricks that feel hacky throughout the whole build process. These might really slow you down during manufacturing (even for low volume production) and, most importantly, reduce the overall quality of the product. Examples: melting the plastic between the Neopixel LED ring cover and the top case part (that just feels...wrong), the battery locking mechanism with zipties (which, honestly, is cool, but still kinda hacky), the 3D-printed knob + tiny nickel strip for the trimpot on the DC-DC module (maybe try bigger potentiometers with high-quality knobs?), and all components that need glue in one way or another (it just looks messy). Of course, since you made this powerbank, I'm sure there are specific reasons behind all of these design choices, but bear in mind that consumers don't like to see non-professional building techniques. They degrade the overall build quality of a product. 3. Finally, try to get in touch with people in the maker and hobbyist electronics community to review your circuit design and building/manufacturing/components sourcing process for this product before you start a funding campaign. That should be relatively straightforward, since your design is open-source, and there's a lot of really smart people on the interwebs. I'm sure a lot of folks like the idea of this powerbank (cause, honestly, there's nothing quite like it out there) and will be willing to pay for it (which is quite a big deal), so you need to have the *_best_* version of this product ready in time for shipping. I don't have any money to invest in a powerbank at the moment, but I'd like to wish you all the best in your crowdfunding endeavours. Cheers, mate! You just earned a subscriber ;-)
Wow, thank you very much for the extended comment; My first 3D print looks bad because it was printed on my home printer as I am forced to go back home as my school closes, then I made myself to invest in another Prusia i3 Mk3s so the next prints look a lot better. I have to admit that many of the things you see are kind of hacky because of several reasons; I want my audience to build it, so some common materials are used and low level solutions are done to make the build easier. Like building the circuit that comes with digital control of the output voltage would add another layer of complexity on to the project. In the commercial version, there would be many improvements, like the pull tab is a single piece made from PP; output voltage would be digitally controlled, and the circuit will be fully integrated. I am currently working with a couple viewers who reached out to me, and several other professionals who I contacted, so the product would be as polished as it can be before production. Thanks for all your feedback, I'll post updates in the community tab.
Dude someone could write a master thesis or even PhD over this. Incredible!. It is for real the most complex, beautiful and teaching DIY build I've ever seen in this platform
Hey, i just discovered your project and it is amazing! I'll definetly be one of the backers for the crowdfunding campaign. Great work! I'm looking forward to any updates
Hi. I have a suggestion. Please do something with trimmer potentiometer, because it has extremely low effective turns available, and could possibly break any time. Trimmers are designed to be set to needed value, not to use them as normal potentiometers. Otherwise, your work is really impressive. Good luck with mass production!
The dedication you put into making it clean and fit perfectly is impressive. I found your video as I'm currently looking for making my how powerbank, but in a waterproof case, with ip67 connections for camping and such. I'm blown by the quality of what you made.
I love that you made it With modular packs the sky is the limit I hope you're able to finish your 2nd one and I'm 100% ready to buy it and I hope I don't miss your crowd funding campaign
Great video. I can not wait to see the comercial "version", I would definetely buy one, when it becomes available. I really like that you build custom things. Bigger companies won't do that kind of stuff. (And sorry for my English. I am from Slovakia 😅🇸🇰)
Really nice! I really do hope that everything will be successful. This needs more audience, I'm sure that there would be a lot of people who needs this without them noticing. At least if I had company, I would invest a lot of money in to this. Also really nice thing that you have sponsor, I'm really happy about that
These are some pretty cool construction techniques! At 8:25 it's a bit confusing: You say to use 2 10nF capacitors, the image shows 2 100nF capacitors and the text shows a 10uF and a 10nF cap. It probably doesnt matter at all what you use, but 100nF for both would be more typical and shoud work without a problem. The one on the input of the regulator is probably not necessary anyway. Also, I would suggest trying to use the same type of screws wherever possible. If M3 will fit, dont use smaller ones for example.
Best thing of your powerbank is multiple serial cell Most powerbank has 1s cell. It limit charging speed even large capacity and support Quick Charge or USB-PD Your powerbank use many chips. Its hard to make own version. But it make many IO and great throughput.
That is so SICK!!! it needs to be sold to the public!! You could be a millionaire buddy!! Get a company to print ya stuff off and you could be making some seriously big money!! I’d PURCHASE THAT INSTANTLY!! It’s so awesome!! 👍😉⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ 👍👍👍👍👍THUMBS UP👍👍👍👍👍
This soo cool cant wait till it comes to production. Also i am curious about what design you would do if you made something bigger like a solar generator 😲🤯 if you were to design something like that, that thing would probably have so much capabilities because it seems like you like to have your finished products to be very be modular. Just an idea and also something i would buy 😁 .
Can I make a suggestion for the AC inverter module? The included inverter only has a US outlet, and other outlet designs are larger, so instead, what about having an IEC C13 connector as it's standard around the world. Granted, you'll need an extra wire to adapt that to whichever plug you have, but it'll allow one module (or two if you do separate versions for 220-240V and 120V) to be used globally and it'll remain as compact.
Maybe, as the DC-AC module needs DC as well, it could be made to lock onto the DC-DC module. Though that would require some sort of voltage adjustments, that could be handled with communicating via a similar side connector, making it easy to add modules that need a specific input voltage. Or the DC-DC converter could be moved into the main module, with the side connector having such a voltage setting system.
180W gaming laptop consumes around 110W while gaming, 180W wall adapter is for the worst-case scenario. My laptop comes with a 230W adapter, but it draws 120W while gaming and 90W while CPU Rendering.
Super awesome! I wish you the best of luck with this project! I will most likely chip in in the crowdfunding myself if the final pricing matches my budget. But please make sure ti double (tripple) check with a senior professional electrical engineer before mass producing it !
Bingo, that the idea with the next version! For this version, I initially planned the current to be around 20A so Pogo pins won't be sufficient but as the design evolved, specification changed so I think Pogo pins are the way to go now.
Sir, I suggest use ip5358 for fast charging ic if you decide to make mass production. It support all phone fast charging type with limitation 22.5w. Hope for your future project. Cheers!
Holy crap! MAKE THIS HAPPEN PLEASE! And for the love of God, make a version that doesn't include batteries (to purchase them separately) Why you ask? By doing that your product would reach more places with less trouble, believe me; I can't get any power bank shipped to my country because of this. Please, consider my request.
About the DC-to-AC module: British plugs and Europeans are bigger than the North American ones and I also saw that these converters for 230V are also bigger But does it still work with maybe more module lenth snd the plug attached to the top and not the side or does it need to be doubled in height anyway?
I’m curious if you have considered designing a charging dock for the battery packs themselves so that if you have say 3 of them, 2 can be charged on the dock while 1 is being used in the battery pack. I’m very late commenting on this but I watched this video a while ago and that was one of my first thoughts after, “I want to make this”. Now I just have to pony up the money for a safe spot welder. Love the work you put into this and will definitely keep an eye out for the version you crowdfund!
Ayyy I’m in the video as a comment!!! Amazing stuff you do man, i really enjoyed the other powerbank but sadly i had just bought another before the video came out. Keep doing what you do!! This is really innovative
oh~man! I just want to search for what Li battery 18650 can do? and then I saw your project，its really full of passion and detail，So cool ! I want to follow your project step and do for myself ..Thanks !!!
I just remembered about this video and check back in to see if I can buy one I'm so keen. I have got enough intelligence to build one as IV made a 18650 power wall but I'm just to lazy
Yo if you really start a company i'd really like to support you! Just so you know! I'm becoming an electronics engineer. But this is going to take another 3 years. But if you got this company running then i'd really enjoy working with you! ^^ Keep it up!
How can I buy this kit? Also i wanted to buy the first model you made that has everything all in one Really amazing . If I had a kid I would definitely buy this so that my child could learn more about circuitry and electronics

Here’s a idea what about using Gallium nitride components to reduce the heat dispassion and to increases the efficiency of the device over all?
Suggestion - Make potentiometer digitally selectable maybe with arduino...by this way we can avoid accidentally rotating the voltage knob and frying the charging device. Awesome work dude. Appreciate your time and dedication to the project.
I will most likey make the voltage digitally controlled in the next version; Thanks for the feedback!

Hi. I have a suggestion. Please do something with trimmer potentiometer, because it has extremely low effective turns available, and could possibly break any time. Trimmers are designed to be set to needed value, not to use them as normal potentiometers. Otherwise, your work is really impressive. Good luck with mass production!

The Most Awesome Build You Created!!!
Keep it up!!!❤️
Never waited so much for a vidoe series to continue
Awesome!
i literally love your projects & how professional they are
Am completely overawed at your detail and carry through. I will await your crowd funding , and buying one
You should sell these as kits without the batteries installed, could help avoid any potential liability problems

I cant imagine the number of problems you would have ran into while designing this
That is partially why this took over 5 months to make. Too long...
As a maker myself I could imagine the pain
very nice invention
If its even possible, mostly cause no one else seems to do it
A 180W dc to dc converter for gaming laptops
the batteries in series make an output of 18.5v and the batteries are 9.8A and 18.5v * 9.8 = 181.3 so I dont think it would be quite enough
180W gaming laptop consumes around 110W while gaming, 180W wall adapter is for the worst-case scenario. My laptop comes with a 230W adapter, but it draws 120W while gaming and 90W while CPU Rendering.

Very beautiful and power full power bank I love it 👍👍👍

The batteries are charged via the CC-CV converter
Here’s a idea what about using Gallium nitride components to reduce the heat dispassion and to increases the efficiency of the device over all?
I also noticed you also solder wires to the Atmega238p can give the reason....
What about a DIY kit of the project until the launch of commercial product, or even after that to cut the labour cost.
Please reply.
dude this battery is amazing, with some external converter this is juste amazing, good job ! 👌👍

Don't worry u will succeed in ur Kickstarter. fosure
Does the expansion slot allow for power to go back into it? I would love to be able to have an XT30 to hook up to a solar power system.
Where is the howto guide to buy it, not gonna waste time building it LOL. This is really great work and very informative.
I would like to preorder one☺
i need 2 of them
I need this model can be charged using solar panel too. SO i can bring this for camping.
dis some Taikonaut level stuff.
Love this however I do not have a 3d printer yet so I can not build one yet.
I'm gonna try to build this! Hopefully by the time I give up I can just buy yours! Haha

About the DC-to-AC module:
British plugs and Europeans are bigger than the North American ones
and I also saw that these converters for 230V are also bigger
But does it still work with maybe more module lenth snd the plug attached to the top and not the side or does it need to be doubled in height anyway?
I'll see if I can fit a international plug on there.
