When I saw the video thumbnail I thought it was clickbait. I thought, "no way. this guy is going to have to.. uhh, he's doing it.. wow. finally someone who deserves my subscription!" Thanks for sharing!
@@horriblyblue6203 dang it.. okay man, you're right... It's such a cool/fun project I wanted to spread some positive mojo about the video. I rewatched it.. hilariously over engineered! You gotta love it!
well done... very creative and encouraging... now you got me thinking to make one myself.. thank you for the parts list, most RUclipsrs don't go extra step like you done. thank you
It's cheaper to just buy a rechargeable 9V, they're only a few dollars. Also you wont have a massive drop in amperage like this one does. I use 9V batteries in Guitar pedals and this one wont put out the correct amperage to run them....
Nice, now place this "9v LiIon" cell in your fire alarm... ... and replace or charge it every 2 weeks. Those boost/step-up boards draw quite some milliamps. Found out the hard way.
Yeah, even without losses from the board, the LiPo used is only 650mAh vs ~550mAh for an alkaline 9V, but he's boosting voltage by 2.5x, so he's ending up with under 50% the original capacity (2.4Wh vs 5Wh). Call it 40% with what the board eats up. Honestly I don't know why he didn't get 3 smaller LiPo's and wire them in series and skip the board altogether, aside from not being able to use USB to top it up. Although then you'd have to toss a resister in to drop the voltage by the extra 2.1V. Hmmm. That's not a good plan either, I suppose, since you're just losing those 2.1V as thermal energy... and we're right back where we started. Well that was a weird rollercoaster of feeling sort of smart to feeling sort of stupid.
Quite a few electronics are sealed this way. While it does make it impossible to work on, these components almost never need repair. The epoxy will not only hold things in place but insulate the wires and protect from oxidizing.
@@cowsagainstcapitalism347 won't the rechargeable battery die after a certain number of charges? Maybe in a year or two with regular use. Better if it was designed so that the rechargeable battery could be easily swapped out when it dies.
Warning: do NOT epoxy or otherwise fully constrain the lipo battery itself! They need to be able to expand as gasses build up due to cell deterioration from (mis)use. Constraining it might cause the cell to burst instead, creating a fire hazard, especially if it happens while charging or full.
Micro USB is cool in the case, I just got high - very neat and beautiful! But stepup dc-dc will drain the battery, slowly but surely, at least it is protected from over-discharge. The switch will not help in any way - what, unscrew the battery compartment every time before and after use? And the question is also how the inevitable dc-dc ripples will affect the accuracy of the device. For me, a much better and simpler solution is a 2S li-ion battery (7.4v), its voltage is enough.
Just watch it again. There are electrical parts which shift it to a higher voltage. Just tell your local police officer you don't believe in it and his wife is good at sucking dicks. He will show you a device which helps you to believe in it. Hopefully it is the yellow one
A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input (supply) to its output (load).
That is pretty nifty but way too much work for me compared to the maybe three 9v battery's I might buy in a whole year 🤔 Watching this video is all the time I'm willing to put out for such a thing 😉 Good times for the builder tho 🙌👍
Каждый раз на время бездействия нужно откручивать батарейный отсек, извлекать аккумулятор и отключать преобразовать. В противном случае аккумулятор будет разряжён. Так себе удовольствие.
Hi there, I'm wondering why you wrote such a comment. This project is totally OK. The pcb is a LiPo charger and an buck-boost converter that wit indeed charge safely a LiPo battery and deliver precicely 9 volts at it's output. If you have any evidence to the contrary feel free to comment.
this comment is way to pretentious/stupid to not point that out :D Mabye try constructive criticism and dont demand something you want "!!!" :D Also: everything is super visible. When you need text or spoken language or instructions to solder a cable on a PCB... i got bad news for you :(
Next time make the video exactly the same as you did. Many people like 'no talking' instructional videos. Some people think what they desire is what everyone wants. See Piaget's theory of egocentricism. Sadly a reflection of childrearing and our societal norms.
Have fun replacing your phone after this whole contraption sets itself on fire due to voltage mismatch. Just buy a purpose built charger that was designed and rated for the load expected. Channels like this are just BS "life hacks" for people that think soldering irons are just hot glue guns for boys.

It is a clickbait as he isn't adding USB charging port to 9V battery. He is building LiOn battery from scratch im 9V battery case...
@@horriblyblue6203 it does the job

But......☺️. So concealed one may mistake it for a regular battery and toss it away.😢
just one word... incredible 👌👍
Awesome. I'm not sure why you put clear epoxy in there--I would've left it out just in case, but this is still a cool project!

@@Gorguruga yes indeed - those pillow type ones will die after a while, some can even expand due to heating.
cool little random fire box !

beautifully crafted and executed idea - learned a lot from this. And this might be the real duracelll at least lifetimewise.
Very nice
Thanks for sharing
I like how at the end you just put a bunch of glue in the battery
Bro, give me the link for copying tape and sponge, please.
So good👍
Quando for colocar para carregar tem que desligar a chave ?
ideo should be played on april the 1st i wonder how many people fell for it.
How many hours can it work on a full charge?
Duracell Engineering: Scribbles rapidly in their ideas notebook!
Nice!👍
I would have opted to use a USB-C port. But nonetheless great job.
Awesome!!
if its a 3.7v battery how did you get 9v out of it doesnt make sense??
Just watch it again. There are electrical parts which shift it to a higher voltage.

Funny
A company makes those commercially
Ah yes, let’s make a rechargeable 9V battery by making it 3.7V
Or you could watch the video and see that he dropped an adjustable voltage boosting board in there...
exactly and then it somehow outputs 9v through the multimeter lol
@@notchos Or you could watch the video and see that he dropped an adjustable voltage boosting board in there...
@@notchos exactly, and there aree people that still fall for videos like this... absolutely disappointing
How 3.7 li-po can give 9 volts? 🤔
You need a regulable step-up board. It could buy from aliexpress from 3€
But this "9v" batteries have 9,7-10v as nominal...
Good idea with strange decisions.
Impressive
you are aware that they sell rechargeable 9 volts my score is 10/10.... 10 points for cleverness and 10 points for stupidity
Lol.. sonjust buy a rechargable battery 🔋🤣.
Good
There's your AAAA batteries lmao
This is a Genius modify... Has anyone $$ priced it out??
About 6 dollars plus a 9volt and some glue
Check adfruit for parts
@@aliciaellis2832 Or just buy a battery like this from Amazon. Lot of these USB chargeable batteries available online.
That is pretty nifty but way too much work for me compared to the maybe three 9v battery's I might buy in a whole year 🤔 Watching this video is all the time I'm willing to put out for such a thing 😉 Good times for the builder tho 🙌👍
Guitar players use dozens of volts, we use them in pre amps, Passive Pickups and effect pedals.

It is clickbait. That's a 4v lipo. Utterly useless. The charger is a 4v usb charger. And then he fake shows 9.01v at the end.. Fake human lies
A tiny one too. No useful capacity
