A good replacement for the clunky switch would be a set of MOSFETs and some latch circuit.

WOW, very smart idea to use this Single Cell Lithium Battery Boost Power!

2nd like the powerbank is gonna be very handy

Sorin, You can find push button switches that are rated to 15A ro 120A. Would be very flush to your case. I found in Chinese online store: 10A 15A 20A waterproof high current metal button switch

This channel done so well since you began. Well done Sorin.👍🇮🇪 I built your design (well the one you use here) of a load. Had no resistors so I made my own out of the wire from an old electric blanket but you can guess what happened. Yeah they got very warm. I have power resistors I found inside an old TV in it now.. Works great 👍😊

Always happy when another Sorin video is released!!

Nice workmanship! I love your cat too!

Finally a legend just posted! Sorry for being Late!

Thanks sorin for your awesome videos as always 👍🏼

Why don't you use an 18 watt powerbank module, which has everything you want!

I love your Videos. Although very easy and simple the main issue for me is the tools and components (Not deliverable to My location From Aliexpress) 😢. I have made DIY flashlight And power supplies using your awesome ideas... Love from India 🇮🇳

Nice power bank👍. Ugly button.

Hi Sorin, missed you. nice to see you a new video I can get some ideas with. I hope you yould also make a video for a 12v powerbank that can be charged just by using a mobile phone charger. as I saw once in an online shop that there is a (12V) 3S LiPo charging module that can be charged with a mobile phone charger. I can't get any info about the type of chip or board it is so I can tell you what board it is... Thanks again for another great video...

Thanks for this video my friend, I am sure that now when newest sodium ion batteries a power bank project can be more interesting. For the switch replacement a circuit with a push button instead or even a touch sensor with 3 secs delay in any of both cases the circuit must be made so only can be started is a load is connected to the power bank

Hello Sorin. Very nice video once again! Wouldn't be nice to add a tactile switch to activate the battery capacity meter? So it would be off, and when you with to know how the batteries are doing you would just press the tactile switch.

Gran video, como siempre te superas, saludos

Finally wait is over ❤☺️

Precise Thermometer = His Finger 😂.

nice video bro, complete details. easy step by step.

Thank you for the nice video!

love these videos. 1S battery config is very DIY friendly. to make better thermal performance, I have found that by layering about 5-10 layers of copper foil tape on the enclosure and then covering that with thin black teflon tape (for max emissivity and insulation) helps draw heat to the outside of the case better. also, black plastic enclosures loose heat much more quickly due to radiative cooling, but if it is going to be placed in sunlight/dash of a car the black color is a negative. I think I will copy this but maybe do an all in one usb-c board (more expensive) and use old ipad 3 replacment batteries which you can cut up into 3 pieces. theyre very thin and have about the same storage as these high spec 18650s. i think theyre around 2-3$ each cell depending on volume/shipping. I think you could fit about 5-6 of them in the same enclosure with an all in one board (~12wh each cell!). also debating doing a series version and using an active cell balancer instead of a BMS. thankyou for uploading

hay Sorin_DIY can make a rechageble AC plz

You can use a latching MOSFET switch that is turned on and off with just an SMD pushbutton. It will handle the 10A like a boss

My Tps61088A circuit was constantly burning. I had to put an aluminum plate on the back surface. Because the adhesive starts to separate from the surface when it gets too hot. I think you should pay attention too.

For the big switch you could design a small circuit with a mosfet that has a latch button that uses a small button and an led for indication

Hi 1st

Please make more videos. And as always loved your videos ❤❤

Wires are little overbuilt 18 awg would have been fine aswell a switch that can handle 5 amps would have worked aswell, but im not a fan of 1s3p batteries in general would go for 3s instead cause its safer, and it is more efficient aswell

For your big switch, replace with a small switch that controls a MOSFET circuit. The MOSFET resistance can be very small and thus be minimum power loss.

Nice design! I notice that it will stay on, when powering low power devices. Power banks usually turn off. And - it can charge while powering another device normal power banks can’t do that either!

You could have use Mosfet in combination with small switch

Excelente 👏

I'm trying to build a 12V battery pack for my astrophotography setup (still figuring out all the parts I need). I was worried about soldering the fuses directly inline. Thanks for the video!

Babe, new Sorin video dropped.

Super tare! Stii ce ai putea face de acum incolo pentru videourile tale... Sa compari la sfarsitul clipului cat te-o costat piesele, cat timp ti-o luat sa faci proiectul, cat costa acelasi device cumparat din compert si pro's n con's si daca overall merita sau o fost un proiect mai mult pentru distractie. cred ca ar da un plus videoclipurilor tale. keep it up! bravo! :)

Very Nice project as usual, but I can't find schematic !

👏 Legend 👏

Found it!!

WOW 👍❤️

Hi sorin next time build superfast power bank pd version

Very nice.

you gotta fix the Echo in that room man. Please and thanks

Cool

Nice

Very nice. Really like this one. Just one question. Would it be possible to make one with USB C PD? Fast charging over USB A no longer works with newer smartphones.

Got to love a good ol' big and ugly switch. Not great in a pocket though.

Push button start switches for cars should fit your bill. Easy to find on flea-bay, and cheap too! So nice to know I am not the only one with over strength hillbilly friends! LOL

Please be careful, that switch is 10amp rated for AC not DC. Consider a mosfet logic switch (Similar to the battery protection board) for your power switch.

Where is the cat?

When u connect ur phone to charge it the voltage goes to 9volts. IS 9V safe for phones?

Use that one

Can you make rechargeable Fan

Why not use a tiny micro switch, with a MOSFET, or two, IRFz44n would probably work, using a logic level gate, just solder it to the battery, negative with a 400ohm resistor from gate to negative, and another 100ohmvfrom gate to switch to positive, and mount the MOSFET tab,(to220 psckage) to the largest heat sink that fits. If it runs too HOT🥵, use another MOSFET, possibly mount them to a aluminum bar, about 6 mm x12-15 mm, and long as possible, then mount small ic heat sinks to the bar with thermal adhesive or screws and thermal grease. It may require different fets with logic level gates, that will turn on with 3.3v maybe use a diode and capacitor to power on the fet, from the 5-12v from the boost converter. Using the battery to power on enough to make 5-12 v, the turn on fully using diodes to prevent reverse current. A smaller package get soldered to PCB is available capable of 15a, 400watts I have a bag full of them, can't recall what the gate voltage is. This tiny switch idea could be a money maker for someone, have jlcpcb , PCB way, or who ever make them and sell on ebay and amazon. Possibly have them make tiny switches also. They offer so many services and so fast as well. Doing metal 3D printing, plastic 3D printed, they can do anything. Having a small pin in a spring with a latch mounted to a pcb, with two pads to solder the switch to and the wires on both sides of the PCB. Then the switch mounts by drilling a hole for the 2mm pin/button, and glue the PCB to the case,or use tiny screws, However , you'd better off using micro switches available.

My question would be does the circuit cut out when the current draw is too low. Most battery banks I can find will turn off after a few minutes, and a few that turn off after 2 hours. Im trying to find one that will stay on with low current draw until the batteries are discharged to the appropriate level, which could take days or weeks.

Hello Sorin I need some advice if you have time to answer. I've built the exact same power bank but with 7 18650 batteries. After trying to charge it for days, it's now completely off, probably dead. Did I make something wrong or idn't I understand the principles of battery charging? Thanks for your help.

SORIN. HERE IS A QUESTION , DOES 1.5amps 9 V hurt the battery , I got an old iphone 5s which original charger is 5v 1A = 5w

Can I just add more battery in parallel to increase the total capacity in this??

Is it possible to build powerbank with NiMH batteries?

Thank you very much for this tutorial Sorin! 👍 Hey.. I have 10 * new high quality 21700 batteries (Vapcell F60 6000mAh) and I want to build a PD3.1 compatible (28V @ 5A) power bank (welding is no problem). But I do not have the required knowledge, so I was wondering if you by any chance could help me out with this? ..at least with the BOM (Bill Of Materials) and provide me with links to the needed components (AliExpress is fine). I wish I had your skills. 🙂

Hello sorin, can i use Type-C USB 3A Polymer Ternary Li-ion Lithium Quick Fast Charging Board for input and want to add 6-8 cells in parallel is 1s bms enough or should i need to add more bms

Hey man i need sum help and questions pls respond to me you are the only one that can answer my question and help 😢 if its possible.

Helo Mr.sorin can we add two output ?

God enlightens you. Could you please remove the power bank box and bring it from where? Thank you

why dont you use slider switch?

Hillbilly Friend!😂

Build electric screwdriver

😀😀😀🔧🔨😍😍😍😎😎👍👍👍

You should consider a 3D printer.

Fast charging for phone is so stupid, boost the voltage at the charger then lower the voltage at the phone. So dumb.

why is your face getting older?😢😢😢

power bank? again? cmon man

good to know you have favored money givers wow lmao
