[@Asu01]

This is soo relatable. The amount of times I decided to cancel building my own circuit because someone in China already made them pre-made and even cheaper, is just astonishing. I find designing and building your own is only worth if the application is very specific or you just want to learn something. Other than those, just get them pre-made. I think you should be a little bit more steady during soldering, those crystallized solder joints are painful to watch..

[@rizaldisony1243]

Or maybe you can make it more powerful than pre-made pcb like episode of diy or buy bms

[@EgonSorensen]

Please don't tell him about flux ;) - often the boards designed in China are under-designed in regards to cooling, components cut to save cost, schematics and bom missing, errors in layout - fixed in other revisions/sellers - and you can't be sure if it has the right/'original' components mounted or not. It is a gamble, for what it is worth

[@44R0Ndin]

He's steady enough while soldering, lead free solder tends to make all the joints look slightly crystallized. That and tin whiskers are why I still use leaded solder. EDIT: I only use leaded solder for electronics, if I'm doing plumbing I use lead-free plumbing solder. I know about the harmful effects of lead, and I use a fume extractor as well as wash my hands after I've touched leaded solder.

[@Kalvinjj]

@@EgonSorensen My experience with Chinese module boards is that they often enough just follow the datasheet typical applications to the letter, a totally no-brainer approach. It probably costs them more to cheap it out removing components and testing (or having someone that knows electronics to that point) than if they just have a quick turn-around with minimal develpment cost, down to 1h board done with auto-router. What they definitely do often enough tho is terrible power supplies or crap component quality, specially filter capacitors. Things probably start to become ugly when they start going with some very no-name ICs, and even that is usually down to the IC being straight out made for crap products and they just follow as told on the manual.

@@44R0Ndin I have absolutely no idea why you need to solder something when Plumbing I thought Plumbing was just sticking a bunch of pipes together and sometimes using some glue to attach some pieces with joints

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

[@jantube358]

I guess they are expensive because you need more cells and a BMS

[@mevk1]

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?

[@ericklein5097]

There are now several available but none of them work beyond 60W. I have another coming in that I ordered last night but my experience has been that no buck boost IC can stay cool enough to handle more than 3A at 20V

@Mikolaj Kraszewski He is designing consumer product, which will require a hell lot of natural curve (or at least, fillets, like the one sit next to his 3D printed charger) for just the look and the feel.

A good CAD is not just a functional and dimensionally correct but also need to look good and feel good in the hand

@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.

Batteries are connected in parallel. No BMS required. Overcharge/overdischarge protection already in the powerbank board. If you want just match batteries, you can simply charge it to the equal voltage separately, then just connect with each other in parallel.

@@kokokoshka-s7c what you could add tho is one of those individual cell protection boards, for the parallel connection they would make sense to avoid overcurrent on the single cell, in case they aren't perfectly matched.
