DIY USB 18650 Li-ion Battery Charger 

Excellent basic idea, but I see a MAJOR "bug" in the implementation: A USB port isn't likely to last very long before being tweaked out of shape and becoming useless from supporting the weight of the battery. Granted, the battery doesn't weigh much, but that relatively small weight is acting on a (comparatively speaking) VERY long lever, effectively multiplying the force the socket "feels". How much does it increase the force? Impossible to say without getting some exact measurements and doing the math, but I wouldn't be surprised if it's somewhere in the range of 5-10 times the weight of the battery. Even worse, that force will be "felt" by the socket for hours at a time as the battery charges. As it stands, I don't expect *ANY* USB socket to be able to survive it for more than a few charging cycles before it gets distorted to the point where it stops connecting properly to anything you try to plug into it. I'd have to go dig up the USB specification stuff to be absolutely certain, but I seem to recall reading that a USB socket is only designed to withstand a very few ounces - think less than half a pound, if it's even that high - of force in any direction other than "straight in" or "straight out". This little idea needs some way to take the downward force exerted by the weight of the battery off the USB socket - Perhaps a sort of "kickstand" at the far end of the charger unit to support it, or a short piece of cable between the USB plug and the charger unit. Either way, it needs SOME method of taking the force off the USB socket, which is, mechanically-speaking, not very strong at all, and very likely to fail quite rapidly if this thing is plugged into it with any regularity.

Boss you are one thing, you have so much intelligence in your head

Very neat assembled thank you god bless you

Great to hear

Great job. Amazing

Superb job

Very good idea 👍👌

Which type of black glue you used and hexoblade for cutting?

Oh man it's perfect👍 Really great work sir

Fantástico trabalho, parabéns

Very nice video sirji

3 pin charging led can work (bi)? If yes then how I can connect with one leg neg of led. Because in tp4056 have 4 points of led 2 negative sides and 2 positive sides? Answer please

I made something similar using an old vape pen that already had all the components I needed. Only mine can charge both the flat top and the button top 18650s. :D

Very good👌

Very unique :-)

The charging module and battery both getting hot, what should I do?

Mantap bossku 👍

Good job... Men. This solar Box what is it name pls.

Easy and amazing

Amazing

What is the simple circuit of the li ion chartering terminal? Just hsving thst in there makes the video simply an assembly of a pre-made battery charger, not exactly one made yourself, but of course you can still be creative, I'm wondering what junk electronics I can salvage to build the charger

Será que pode ensinar como fazer um carregador para pack de baterias 18650, mas com indicador de quando a carga está completa? Um abraço obrigado

what is that potting compund called?

I like your style to do these videos, so quiet...shh shh. Be careful, somebody can heard your next new great ideas! Keep your style, I subscribe

very nice. except that a ready made charger costs less than the glue you need to make your own and does not require the need of 3rd hand, drill, soldering tools, dremel and so on.

Very good video he

Very nice

very good

Nice bro ✊ 💝💝💝💝🇲🇦🇲🇦🇲🇦🇲🇦🇲🇦🇲🇦🇲🇦🇲🇦❤

super🇮🇳👍👍 Kuki

He sure is a handy man. Nice job, but battery charger are so cheap that it might end up costing you more on parts if you don't have some of the mechanical parts with you already

Can such a power bank be made for Cell recharge with regular ordinary or rechargeable battery for journey?

Nice vido

digital maltimitar banaye

Via. USB Port to kothao pai na

Sir mere ko eisa battery charger banake milega kya please sir

👍👏

I want one bro

Genius. How long does it take to charge them?

👍👍👍👍👍👍👍👍👍

1:26 If you're refining PVC with rotary tools or any other way, in which the PVC can heat up a lot due to frictional heat, make sure to wear a mask and do it in open air because nasty chloride gets set free when PVC is melted.

How much current required by Li ion cell. ? . BMS rating ?

what if you will make a double battery charger? are you going to use 2pcs 18650 Li-ion Charger (TP4056)?????

He'llo sir

Is the aa battery charger

Wow

Mere bhi banana hai

Price

What kind of wood is that? 4:10

time are precious nowadays.....why not make a paralelle charger

👍👍👍👍 🇦🇿
