HACKED! : Powerbank gets a Fast Charge Feature
video description
ChiPhy IC for example. It would be very interesting to go more deeply to It. I imagine e. g. powering stepper motor with my powerbank. Thank you for your great content!

Hi GreatScott! Sorry for bothering you but I really have a question here and I need your help.
I'm trying to boost my LDO voltage of 3. 3V 60mA to 5V 3A using a switch boost converter before entering a BMS IC to charge a battery storage.
Since I want to get That 3A, I would need to amplify the current of 3. 3V 60mA to 3. 3V 5A before entering the switch boost converter. So, would using an opamp with emitter follower help solve that?
Thank you in advance, bro.

I always find it very interesting see different people do electronic hacks. Wish I could do but don't have the expertise or the equipment so I'm forced to go buy a new battery Bank. Enjoy watching the video and see how things are put together even if I don't fully understand.

Very handy video, I am currently building a couple of power banks as well as two variable bench power supplies, I am building in CC & CV into both but I have one of those battery charging stations that you showed on order, just waiting for delivery.

I re celled a dell battery. got new cells and when I connected it to the battery pcb. It refused to output power. Tried jumpstarting the BMS no go. Checked the pcb for any shorts. No go. Can you input anything. Thanks

Have a google for B0829YCVV1 which is a 10'000mAh power bank that supports USB C PD 18w charging and also outputs QC3. 0 at about 18w.
I have 2 of them and the fast charge is pretty good: -)

What Is the advantage of using 3x2 in series with 7 volts instead of 6 in parallel? With the voltage booster?
Please somebody reply me because I only see a loss of 50% of the powerbank capacity

Could you show how to cut down the charging time from being hours to minutes when it comes to recharging huge battery packs that you assembled on your own and the different approaches of one?

Can you use bjt for limited current charging, by simply limiting collector current and apply battery to v+ and collector pin. Then voltage across battery terminal increases gradually

Instead of that switch why don't you use a mosfet and attiny85 to toggle between two modes. as you are a genius in programming. i would like to see one like that.
