Hello, looked at the video, also decided to test the small-sized PB on the current and the screw, briefly gave 3a, keeps 5,02V, excellent, it will definitely not be in the operation of this regime. With respect.

All healthy, I went to Ali to buy a building for 8 cans of 18650 and Cheto did not understand where the prices of 750r (without QC) and 950r (QC) did not understand. Separately, the board Q.C 3.0 costs 150-250r from power. I just do not understand what sense if you can take the Redmi Power Bank for 20,000 ready for 1300r ready, which clearly has efficiency of returns and other parameters higher than this China garbage collected from a ram and sticks. I may not look ... In general, I thought a fee separately buy, but where to take the case? In general, I do not understand the pricing is over. Burnt ... What options what options, add to the cap chtoli the options taking into account the efficiency and voltage to which discharges the bank and prices, this will help many applicants.

* tagir140 These are ready-made solutions for those who have a bunch of free lithium batteries. And yes, this solution with batteries (if you buy them) will be more expensive.
But on the choice: you want to buy finished chalk, you want to collect from the details.
For each of these options there are many supporters)
Here is my top boards with QC:

2) https://aliexpress.com/item/-/4000014777280.html

3) https://aliexpress.com/item/-/1005001490060147.html

On the first 2 boards (on the second board only in version with Type-C)
There is also pass-through charging. At least in those boards that came to me, she is present.

And this is if the most compact fee is needed and the fast charge is not needed:

Recently thought about creating a chalomb for his MacBook about 2019. There are many cans in stock, looking for a fee that can support PD4.0. Help, please, with search. In the forehead, the Chinese do not answer anything concrete, they say, go, read the description in which there is nothing about the protocols.

From the found, but for me it is not clear whether for my goals is suitable:

PD double-sided module quick charging laptop buck-boost mobile power DIY printed circuit board NANXIN SC8802 Max 60 W

Bidirectional fast charging QC3.0 / PD65W, Mobile Charging "DIY", set to raise and pressing treasures, printed circuit board 20 V

PD3.0 PD2.0 100 W USB PD Type-C to DC Scam Spoof Quick Charge Trigger Detector, Module Power Controller for Laptop

YZ917 Bidirectional PD Mobile Power DIY Car Charger 60W Full Protocol PCB

QC4.0 QC3.0 TYPE-C 100W Suitable for quick charging SCP / FCP

And this seems to be what you need and price the norm

There are also automobile charging, promise to 65W to issue PD
Help, brothers

Depending on what. Ordinary Chinese banks, with a small capacity, I think 2000-2200 mAh.

* Nomatss. , there is a whole suolanta of Qc-triggers, QC charging))
Most do not treat payments at all. Is that the second link, but here is the price
In my opinion, to give more than 2000 rubles per fee only - it is too much. For this price, you can find the finished panibank and even at 20.000 mAh.

I bought many boards for plunger, but so far this is the most adequate:
https://aliexpress.com/item/-/4000869375300.html

QC4.0 support is present in the specifications, but I can not check, but I can confirm the presence of QC 2.0-3.0.
There was a chalktank on its basis and small tests:

Hello, I would add that home-made PB is also created under your claims, which are simply not available in nature. Decision of course expensive, but it is worth it, because Some new properties of the board are found, which did not suspect before. In particular, I modified the charge from the cigarette lighter. The source scheme on 500mA transistors. Forced to 2a, it works, but long-term work on this mode leads to overheating of the output transistor. I installed the radiator, you can now charge 1a and briefly up to 2A from the cigarette lighter. Simulated the charge process of a small-sized PB from this bitterness. PB discharged to a cut-off for experience. At first, the current was 1,3a at a voltage of 4.85V. The tension of the county as heated began to decrease slightly and stopped at 4.71. The charge current began to smoothly decrease far from synchronously with a decrease in voltage and at the end reached 0.71a and remained so almost until the end of the PB charge, then at the end of the charge fell as usual. It means that some kind of software PB monitors extremely low voltage developed by a specific source (in this case by the county) and adjusts the charge current into the balance with this minimum voltage. On the usual network of 5V, the charge current is installed immediately, 1,5A, on the samsung - 1,9a, and remains constant to a decrease before the charge ending in the usual manner. On the PB display, the voltage and current are also displayed. Accurate control over a successively USB test. With respect.

Guys please tell me how you can call 12 volts as possible on Paverbank with a quick charging, whatever the trigger



Rep: (98)
Antianton23 @ 03.01.21, 22:58*
As possible on the Paverbank with a quick charge call 12 volts

The consumer must have a compatible fast charging protocol. Forcibly to force the PB to give 12 volts without a trigger will not work.

Hello, in Datasheet on IP5322 found: "IP5322 Synchronized Switch CHARGING SYSTEM SUPPLY UP TO 5.0A CHARGING CURRENT. IN CONTROL OF IC AND
Battery Temperature and Input Voltage Loop, Intelligently Adjust Charging Current. "This is how it happens in practice. Regards.



Rep: (159)
* AntiAnton23 You can buy a boost module, connect it to the battery outputs, set up at the output 12 V, but ...
It will still have to place somewhere on the housing)
